Description

An external fixator for internal jugular vein catheterization

technical field

The utility model relates to the field of medical appliances, in particular to a structure of an external fixator for internal jugular vein catheterization.

Background technique

Deep venous catheterization is a commonly used surgical treatment technique in intensive care. In the treatment of critically ill patients, it has fast infusion speed, quick onset of effect, and obvious effect. Difficult puncture and pain caused by repeated punctures, especially in the field of cardiothoracic surgery, internal jugular vein catheterization is widely used. The catheter is a special silicone tube that is punctured through the skin and left in the superior vena cava. After the catheter is placed, in order to prevent the catheter from protruding, it is first sutured on the skin of the patient's neck, and then fixed with a sterile transparent film. However, due to the needs of treatment for critically ill and major surgery patients, the end of the deep venous catheter often needs to be connected with multiple pipes, three-way pipes, "T"-shaped pipes and other devices. The more pipes are connected, the greater the pressure on the neck skin. It is easier to cause the suture thread to tear off the neck skin, and even the catheter is pulled out and endangers the life of the patient. ②Because after major surgery, patients are often weak and sweat a lot, and the pressure at the end of the catheter causes the adhesive tape and transparent film to curl up, not stick firmly, and fall off, resulting in frequent exposure of the puncture point and increasing the risk of infection for patients. Clinically, it is often the case that the film is curled and peeled off, and the nursing staff will frequently replace the film, and use other adhesive plasters to stick it on the face and neck. On the one hand, frequent replacement of the sterile film increases the economic burden of the patient. On the other hand, the adhesive tape will cause the patient The hair and beard of the patient's hair and beard stick together, which increases the pain of the patient and affects the appearance when it is removed; ③ some patients will have skin allergies to the existing fixing materials such as adhesive plasters and sticking films. Especially for infants and young children, the skin of the neck is tender and sensitive, especially when the external temperature rises, the skin of the neck of the child will appear itchy or even ulcerated, and the pulling of the end of the catheter on the skin of the child is more likely to cause neck pain. Skin tearing off. And these three deficiencies are still the problems existing in internal jugular vein catheter fixation at present.

Utility model content

The purpose of the utility model is to provide an internal jugular vein catheter external fixer with simple structure and convenient use.

In order to achieve the above purpose, the utility model provides an external fixator for internal jugular vein catheter, which includes a fixing belt that can be sleeved on the patient's ear, and a fixing clip that is arranged on the fixing belt. The catheter end of the tube is connected.

Preferably, the fixing strap is provided with an adjusting clip that can be adjusted according to the size of the patient's ear, and the adjusting clip divides the fixing strap into a first part that fits around the patient's ear and a second part that is used to fix the fixing clip. part.

Preferably, the fixing clips include several, and the several fixing clips are arranged side by side on the second part of the fixing belt.

Preferably, the fixing clip is provided with an opening and a clamping part communicating with the opening, and the width of the clamping part is smaller than that of the opening.

Preferably, the fixing belt is made of soft material, flat and has no edges and corners.

The external fixer for internal jugular vein catheter of the utility model can firmly fix the internal jugular vein catheter, avoiding the prolapse phenomenon of the catheter caused by the dragging of the catheter end to the neck skin of the patient; at the same time, avoiding the dragging of the catheter end to the neck skin, It can effectively increase the firmness of adhesive tape and transparent film, prevent film curling, ensure safe infusion, facilitate nursing observation, and is comfortable and beautiful.

Description of drawings

Fig. 1 is a schematic structural view of an external fixator for internal jugular vein catheterization according to the present invention.

Detailed ways

Please refer to FIG. 1 , the internal jugular vein catheter external fixator includes a fixing belt 1 , a fixing clip 2 , and an adjusting clip 4 . The fixing belt 1 is a soft, flat and non-angular fixing belt, which can be adjusted according to the size of the patient's ear through the adjusting clip 4 . The adjusting clip 4 divides the fixing strap 1 into a first part 11 which is sheathed on the patient's ear and a second part 12 for fixing the fixing clip 2 . The fixing clips 2 include several, and the several fixing clips 2 are arranged side by side on the second part 12 of the fixing belt 1 . The fixing clip 2 is fixedly connected with the catheter end 31 of the internal jugular vein catheter 3 . The fixing clip 2 is provided with an opening 21 and a clamping portion 22 communicating with the opening 21 , the width of the clamping portion 22 is smaller than that of the opening 21 . The fixing clip 2 pushes the fixing strap 1 inwardly to the narrowest part of the clamping portion 22 through the opening 21 , thereby fixing the fixing clip 2 on the fixing strap 1 . Several fixing clips 2 on the fixing band 1 can be placed, that is, catheter ends 31 of several internal jugular vein catheters 3 can be connected. When the infusion starts, the catheter end 31 is positioned at the opening 21 of the fixing clip 2 to keep the fluid path unobstructed. When the infusion is completed, push the catheter end 31 to the clamping portion 22 of the fixing clip 2 to close the liquid path. At this time, the pressure of the internal jugular vein catheter 3 and the catheter end 31 is almost all concentrated on the fixing belt 1, which can greatly reduce the pressure on the suture line of the patient's neck vein catheter, and avoid the dragging of the catheter end to the patient's neck skin. Causing the catheter to prolapse.

Although the embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the above specific embodiments, which are only illustrative and instructive, rather than restrictive. Under the enlightenment of this specification, those skilled in the art can also make many forms without departing from the protection scope of the claims of the present invention, and these all belong to the list of the protection of the present invention.
