Scalp Vein Set  - Scalp Vein Set Assembly Machine

With the development of society, the structure and function of blood circulation in the human body have gradually become clear, and the methods and appliances for administering drugs through intravenous routes have also been continuously developed.

For most acute and severe patients and some patients who need special treatment, intravenous medication is often a fast and effective choice. In the impression of many patients or their family members, an intravenous infusion needle is a slender steel needle connected to an infusion tube. In fact, there are many types of intravenous needles available for clinical use.

At present, the clinically common and more commonly used ones are mainly the following: scalp vein set, venous indwelling needle, central venous catheter (CVC), peripherally inserted central catheter (PICC) ), infusion port (POR, implantable venous access port), etc.

The scope of application and main features of intravenous infusion needles.

1. Scalp vein set

This is the most familiar and widely used intravenous infusion device for ordinary patients. Scope of application: ①Single treatment, intravenous infusion with short duration (usually <4h). ②It is often used for a single collection of venous blood samples.

Advantages: It can be removed after the treatment, without affecting daily life.

shortcoming:

①When used in patients with poor vascular conditions or unconsciousness and unable to cooperate well, the extravasation of the liquid medicine is prone to occur, which may lead to chemical phlebitis, and even cause serious complications such as local skin swelling, blisters, and necrosis disease.

②In the process of infusion therapy, patients are required to limit the movement of the needle limbs as much as possible, so that the comfort is significantly reduced.

2. Indwelling needle

Also known as intravenous trocar, it has been used more and more clinically in recent years, gradually showing the trend of breaking the “long-term monopoly of the top spot” with steel needles on the venous scalp.

Scope of application:

①In the case of a large amount of intravenous infusion and a long course of treatment (several hours to several days).

②It is especially suitable for the elderly, children and restless patients.

③Infusion of biological and blood products is required.

advantage:

①The operation process is simple, because the needle tube can be indwelled in the patient's vein during the treatment interval, which avoids the damage caused by repeated puncture of the blood vessel in a short time.

② It can effectively reduce the risk of drug extravasation.

③The patient's comfort level is higher, which increases the willingness to cooperate with treatment.

shortcoming:

① Although the indwelling time is longer than that of scalp steel needles, it should generally not exceed 3 days (72h).

②A small number of patients with poor vascular conditions will have phlebitis.

Precautions:

①The intravenous indwelling needle should not be routinely used for blood collection (except for short-term applications). ②Avoid binding the blood pressure monitor cuff and tourniquet at the proximal end of the limb where the indwelling needle is placed.

②It is not recommended for the continuous infusion of the following liquid medicines: parenteral nutrition (fatty milk, amino acids, etc.), with a pH lower than 5 or higher than 9.

3. Central venous catheter (CVC)

In CVC, catheters are inserted into the upper and inferior vena cava with larger diameters mainly through the internal jugular, subclavian, and femoral veins and kept for a certain period of time.

Scope of application:

①A large amount of liquid is required to be refilled quickly.

②The course of infusion therapy is 2 to 4 weeks.

③It is necessary to infuse liquids with vascular irritation, especially liquids with large molecular weight, hypertonic or viscous, such as fat emulsion, amino acids, mannitol, etc., and liquids with pH<5 or >9.

④When peripheral vein puncture is difficult.

⑤ Access to vascular interventional therapy.

Advantages: Compared with intravenous indwelling needles and scalp steel needles, the time that CVC can be indwelled in the vein is greatly increased, and the patient's vein irritation is relatively small.

Disadvantages: CVC has higher requirements for the operator, and there is a risk of complications such as pneumothorax (intubation in the subclavian vein), catheter infection, and venous thrombosis (intubation in the femoral vein).

Precautions:

①In order to effectively prevent infection, change the patch 1-2 times a week, and take care of the skin at the puncture site. If there is redness, swelling, or exudation, deal with it in time.

②The CVC catheter must be removed before the patient is discharged from the hospital, and the catheter cannot be taken out of the hospital.

4. Peripheral vein implantation of central venous catheter (PICC)

PICC is like an intravenous indwelling needle, the catheter is inserted from the peripheral vein, but the catheter can always enter the superior vena cava.

Scope of application: It requires medium and long-term intravenous infusion treatment, and can be used for infusion of various drugs, especially some chemotherapeutics and other drugs that can stimulate the veins. 

However, it cannot be used for high-pressure injection pumps to inject contrast media (except for high-pressure resistant catheters).

Main advantages and disadvantages: The general PICC catheter can be kept for about 1 year if it is properly maintained, and it is also convenient for patients to keep them when they are discharged from the hospital and use them in community treatment.

Precautions:

①In order to ensure the smooth flow of the catheter, the patient needs to go to the hospital every week to be maintained by a professionally qualified nurse. The maintenance content usually includes: checking the catheter for slippage and blockage, cleaning the local skin of the puncture site, and replacing the film.

②Patients should keep the local skin clean and dry at ordinary times, and seek professional help if the film is curled or loose.

③When dressing, wear the tube side sleeve first, then the tube-free side sleeve; when undressing, first take off the tube-free side sleeve and then the tube side sleeve; avoid hooking the tube out.

④Can I take a shower if I have a PICC?

The answer is yes, but baths and baths should be avoided; before showering, wrap plastic wrap around the puncture site for 2-3 times, and fix the upper and lower edges with adhesive tape; check for water ingress after showering, and change it if necessary. medicine.

⑤The arm on the side of the tube should avoid extracting heavy objects, exerting too much force or moving in a large amount.

⑥A particularly important point: If the catheter has slippage, do not push the catheter directly back into the blood vessel by yourself, but go to the hospital in time to be handled by professional nursing staff.

5. Infusion port

The infusion port is an infusion device directly implanted under the skin, which can be left for several years and has little impact on patients' lives. The infusion port is mainly suitable for patients who need long-term intravenous infusion of drugs. It is suitable for infusion of various drugs, especially chemotherapy drugs, parenteral nutrition solutions, hypertonic liquids and other special types of drugs. It is also suitable for peripheral puncture particularly difficult. patient.

After the wound of the implantation operation in the infusion port has healed, the patient can live as usual. It should be noted that: go to the hospital for care and maintenance once a month; avoid external impact on the implanted infusion port; care during the infusion port insertion period must follow the guidance of professionals; if the skin at the infusion port appears red, swollen, and hot , Pain and other conditions must go to the hospital for treatment in time.

Regardless of the development of technology and tools, the goals of medical staff and patients are always the same: to choose the most suitable treatment methods and equipment for patients, to ensure effectiveness, security, and comfort.

Scalp Vein Set Assembly Machine configuration difference

The configuration of the Scalp Vein Set Assembly Machine is absolutely different. What we are talking about here is not only the electrical configuration, but also some common wearing parts.

For an automated assembly equipment, both low-end configuration and high-end configuration can make the equipment operate normally, but the difference between high-end and low-end lies in the failure rate during later use. It is undeniable that high-end configuration equipment In the later use process, the performance is better and the failure rate is lower. However, the price of high-end configuration is naturally higher.
