Description

A CVC fixed protective cover

technical field

The utility model relates to a protective cover, in particular to a CVC fixed protective cover.

Background technique

The subclavian vein catheter (CVC) is widely used in stem cell transplantation, plays a very important role in the treatment of stem cell transplant patients, and is the life channel of stem cell transplant patients. Due to the short catheter of CVC, it is easy to detach the tube. The puncture site is under the clavicle, close to the respiratory tract, and is susceptible to external bacterial infection. During the indwelling process, care should be taken in all aspects. In addition, whether the catheter can be safely and effectively fixed is directly related to whether various treatments can be carried out well. Maintaining the normal function of the catheter, reducing the occurrence of complications, and increasing the comfort of the patient are the focus of catheter care and the key to hematopoietic stem cell transplantation. Patients with stem cell transplantation are immunocompromised, and catheter care should be taken to reduce or avoid infection. Fixing the CVC can make the patient more comfortable and improve the patient's quality of life. At present, in clinical practice, most of the catheters and infusion joints are covered with gauze dressings or transparent plasters. The infusion joints connected to the catheters are wrapped in gauze and tied to the patient’s clothes. Because the position is fixed, it cannot be adjusted according to individual differences, and the CVC plaster is easy to warp. , the maintenance frequency increases, the nursing workload increases, and the patient's cost increases, and because of the need to continuously maintain the CVC application, the patient's gown cannot be fully buckled, which is not conducive to keeping the patient warm.

Contents of the invention

The utility model aims at the above-mentioned disadvantages, and provides a CVC fixed protective cover. The protective cover is provided with a sleeve body. When the CVC catheter is fixed, the end of the CVC catheter located outside the patient's body is directly inserted into the placement cavity from the catheter insertion port, and then Choose the position to be fixed according to individual differences, and then stick the sleeve body on the patient's body with tape. The sleeve body can better protect and fix the CVC catheter, which is very convenient.

The purpose of the invention of the utility model is achieved through the following technical solutions: a CVC fixed protective sleeve, including a sleeve body made of soft materials, a placement cavity for placing a CVC catheter is provided in the sleeve body, and a sleeve body is opened and placed at the upper end. The catheter extending into the cavity is connected to the mouth, and the lower end of the sleeve is provided with an infusion set for connecting the infusion set to the CVC catheter. The infusion set is connected to the placement cavity. cover.

When fixing the CVC catheter, the end of the CVC catheter located outside the patient’s body extends directly into the placement cavity from the catheter entrance, and the sleeve can be fixed on the chest wall of the patient along the direction of the catheter, and the position of the sleeve can be adjusted according to individual differences. Just stick the sleeve on the patient’s body with adhesive tape. In order to avoid the patient’s allergy to the adhesive tape, you can use anti-allergic tape. No need for infusion or when the infusion is over, the cover will close the infusion set at the lower end of the sleeve to prevent other objects from coming in. The mouth of the infusion set touches the CVC catheter, which can protect the CVC catheter very well; when infusion is needed, open the cover, insert the connection end of the infusion set from the mouth of the infusion set into the placement cavity in the sleeve, and place the infusion set The connecting end can be connected with the CVC catheter. When the utility model is used, the CVC application sticks to the CVC puncture above the sleeve body, and the sleeve body connects the exposed part of the catheter other than the CVC application with the infusion joint, and the nurse hardly affects the CVC application when operating the CVC catheter. Fixed, so the CVC application is not easy to lift, can reduce the number of maintenance, reduce the cost of patients, and reduce the workload of nurses, and the utility model can better protect and fix the CVC catheter when the sleeve is infused or not .

Preferably, the sleeve has a cylindrical structure when it is not deformed, and the combination of the catheter insertion opening, the placement cavity, and the infusion set insertion opening forms a through hole in the middle of the sleeve of the cylindrical structure.

Preferably, the cover body is made of non-woven fabric, and there are more than two rubber strips for pasting adhesive tapes on the outer surface of the cover, and the rubber strips are parallel to each other. Non-woven fabric is a kind of skin-friendly material, and the cover body is made of non-woven fabric, which can make the patient more comfortable. Because the cover body is made of non-woven fabric, if the tape is directly pasted on the cover body, when the tape is replaced after a period of use, tearing off the tape will cause damage to the cover body, and there is a rubber strip on the cover body, and the tape is pasted on the The cover body is fixed on the rubber strip, which will not cause damage to the non-woven fabric part of the cover body, and can prolong the service life of the cover body.

Preferably, the sleeve is hinged to the cover, and a Velcro that cooperates with each other is provided between the outer side of the sleeve and the cover.

Preferably, the hair surface of the Velcro is fixedly installed on the cover, and the hook surface of the Velcro is fixedly installed on the outer surface of the casing.

As a preference, two rubber clamping strips corresponding to each other are fixedly connected to the inner side of the sleeve, and two connecting buckles for connecting the two rubber clamping strips are arranged between the two rubber clamping strips. When the rubber clamping strips are connected together through the connecting buckles, the position between the two connecting buckles forms a clamping area for clamping the CVC conduit. In normal times, there is no need to connect the two rubber clamping strips together through the connecting buckle. When the CVC catheter needs to be further fixed due to the patient's condition, the two rubber clamping strips are connected together through the connecting buckle. The clamping area between the rubber clamping strips provides a more effective fixation of the CVC catheter.

Preferably, the connecting buckle includes a male button and a female button that cooperate with each other, and the male button can be embedded in the female button, and the male button and the female button on the same connecting button are respectively arranged on two rubber clamping strips.

Compared with the prior art, the utility model has the following beneficial effects: the utility model uses a sleeve with a cylindrical structure to fully wrap and fix the part of the CVC catheter outside the CVC application, avoiding the end of the CVC catheter from being exposed to the outside, reducing Possibility of infection, the sleeve is made of non-woven skin-friendly material, which can make the patient more comfortable when using the utility model. The sleeve can be fixed on the chest wall of the patient along the direction of the catheter through CVC application, and can be adjusted according to individual differences position, so that the CVC is fixed more firmly, and the CVC application is not easy to lift, which can reduce the number of maintenance, reduce the cost of patients, and reduce the workload of nurses.
