Description

Special applicator for femoral vein catheterization

technical field

The utility model relates to the technical field of medical auxiliary products, in particular to a special applicator for femoral vein catheterization.

Background technique

Intravenous catheterization is a commonly used treatment method in clinical work. It is widely used in the nursing work of the ward, because the infusion needs to be carried out every day. In order to reduce the pain of the patient's daily puncture of the vein, a trocar can be placed in the vein, and even considering that the patient needs long-term infusion, the infusion can be placed in the vena cava catheter. Central venous catheterization is a kind of special puncture tube that is punctured through the skin and placed in the central venous cavity. At present, subclavian vein and internal jugular vein are mostly used in clinical practice. Medical approach to central venous pressure. Due to the advantages of long retention time, wide variety of infusions, and simple methods, central venous catheterization is a practical and reliable means of monitoring and treatment such as rapid infusion, monitoring, and nutritional support in the emergency rescue process. Femoral vein puncture catheterization is a commonly used method of deep vein catheterization in clinical practice. The veins on the back of the hand and arms used for infusion are superficial veins. The superficial veins are relatively thin, and the infusion volume and speed should not be too fast or too large. The femoral vein is a deep vein, and the femoral vein is relatively thick. Therefore, a catheter can be placed in the femoral vein, and the central venous pressure can be measured or a relatively large amount of fluid can be infused through the femoral vein. Femoral vein catheterization is generally suitable for patients with long-term infusion. If the peripheral veins have hardened and collapsed and are not easy to puncture, femoral vein catheterization can be indwelled for infusion. It is especially suitable for patients who need long-term total parenteral nutrition therapy. In addition, some patients with major trauma or major surgery need a large amount of fluid infusion or monitoring of central venous pressure in a short period of time, and femoral vein catheterization is required.

At present, when medical staff perform clinical care (CVC application replacement), the patient's puncture point often oozes blood, and the joint needs to be fixed with 3M adhesive tape, and sometimes it is pasted everywhere, which is neither beautiful nor easy to fall off. In addition, existing applicators are prone to crimping and falling off.

Utility model content

The purpose of this utility model is to provide a special applicator for femoral vein catheterization, which can reduce the situation of bleeding and seepage at the puncture point of patients. The case where the applicator is curled to prevent the applicator from falling off during use.

Embodiments of the utility model are achieved in that:

The embodiment of the present application provides a special applicator for femoral vein catheterization, which includes an applicator main body. The upper part is provided with a fixing area corresponding to the venous catheter, and a fixing device is arranged in the fixing area.

When the utility model is in use, the material of the applicator body is 3M sterile self-adhesive applicator, which has a self-adhesive function and is suitable for medical use; when the medical staff uses it, they first need to find the patient's puncture point and the position of the joint , then press the tablet and the fixing device to correspond to the puncture point and the joint, then attach the main body of the applicator, and finally press the tablet so that the tablet can inhibit the bleeding and exudation of the patient's puncture point (sterile cotton can be placed under the tablet) , and secure the connectors with fixtures.

Infusion dressings mainly include gauze dressings and transparent dressings. Transparent dressings are also called film dressings, which are made by coating one side of an ordinary medical film with pressure-sensitive adhesive. Most of the materials for making films are some transparent polymer elastomers, such as polyethylene, polypropylene, polyurethane, polylactic acid, etc. Among them, the film made of polyurethane material is soft, transparent, elastic and breathable, and is an excellent material for preparing medical dressings. Film-type dressings have almost no absorbent properties, and their control of exudates depends on their transmission of water vapor, and the transmission speed depends on their molecular structure and film thickness. An ideal transparent dressing would breathe at a rate comparable to that of normal human skin.

The utility model can reduce the bleeding and seepage of the patient's puncture point by setting the anti-seepage area and the tablet, and the fixing area and the fixing device can fix the joint (single-lumen catheter, double-lumen catheter) without using 3M adhesive tape is used for fixing, which reduces the expenditure of the department, is beautiful and not easy to fall, and has good practicability.

The ventilation holes can improve the breathability of the main body of the application, reduce the discomfort of the skin around the puncture point of the patient, and improve the use experience of the patient.

In some embodiments of the present utility model, air holes are provided in the anti-seepage area. Since the anti-seepage area is equipped with a pressing tablet, which is used to reduce the bleeding and seepage of the patient's puncture point, the skin of the patient in the anti-seepage area is more prone to discomfort, and setting air holes in the anti-seepage area can reduce the risk of bleeding. Patient discomfort.

In some embodiments of the present utility model, the material of the pressing sheet is rubber. Tablet pressing is to reduce the bleeding and exudation of the patient's puncture point through the effect of pressure. Therefore, the material should not be too soft, and the harder material will easily cause discomfort to the patient. Therefore, the rubber should be moderately soft and hard. Medical rubber can be divided into two categories: in vitro and in vivo. The rubber used is NR, IIR, PU and silicone rubber. According to the product structure, it can be produced by molding, injection molding or extrusion molding and continuous vulcanization. Products are widely used in medical and health institutions and the pharmaceutical industry.

In some embodiments of the present utility model, the above-mentioned anti-seepage area and the pressing sheet are arranged in the middle of the applicator main body. The main body of the applicator is mainly used to fix the venous catheter, and the anti-seepage area and the pressing sheet need to be set at the puncture point of the patient. The tube has the effect of uniform fixing.

In some embodiments of the present utility model, there are two fixing devices.

In some embodiments of the present invention, the above two fixing devices are respectively arranged on the extending side of the fixing area.

The two fixing devices can play a good fixing effect on both the single-lumen catheter and the double-lumen catheter.

In some embodiments of the present utility model, the above-mentioned fixing device is one of fixing clips, Velcro or straps. The fixing clip can use the medical catheter fixing clip, which is made of ABS+silicone; the Velcro can use the infusion tube fixing sticker; the strap can use the infusion tube strap; the material of the Velcro and the strap are both polyester. All three are commercially available products, and their specific structures will not be repeated here.

Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

(1) The utility model can reduce the bleeding and seepage of the patient's puncture point by setting the anti-seepage area and the tablet, and the fixing area and the fixing device can fix the joint (single-lumen catheter, double-lumen catheter) , no need to use 3M adhesive tape for fixing, which reduces the expenditure of the department, is beautiful and not easy to fall, and has good practicability.

(2) The applicator body of the utility model is set in a circular structure, which can reduce the curling of the applicator and prevent the applicator from falling off during use.
