Description

Hemodialysis catheter sheath

Technical Field

The utility model relates to the field of medical supplies, especially, relate to a hemodialysis pipe sheath.

Background

The hemodialysis catheter is also called a double-lumen venous catheter and is used for leading out blood of a human body and returning the blood to the human body after dialysis. When the hemodialysis catheter is used, the front part is placed into a human vein, and the back part is exposed out of the human body. Hemodialysis pipe needs to be kept for a long time, when not dialyzing, in order to avoid bacteria invading human body and prevent complication, at present, a gauze piece is often adopted to cover the hemodialysis pipe entering the human body, and is rolled into a cylinder to cover the hemodialysis pipe, and then the gauze piece and the gauze cylinder are stuck on the human body through adhesive tapes. During dialysis, the gauze cylinder is detached, and the hemodialysis catheter is connected with dialysis equipment to perform hemodialysis.

The disadvantages of the conventional methods are: 1. the operation of rolling the gauze into a cylinder is troublesome; 2. the hemodialysis frequency is usually three times a week, the whole gauze cylinder needs to be detached every time, the gauze cylinder needs to be sleeved and pasted after dialysis, or the gauze cylinder needs to be manufactured and pasted again, so that the hemodialysis machine is troublesome, and patients feel uncomfortable due to frequent tearing and pasting of the adhesive tape; 3. after the gauze cylinder is sleeved on the hemodialysis catheter, whether the arteriovenous end of the catheter is in a clamped state or not cannot be observed.

In addition, chinese patent ZL201920109895.0 discloses a central venous double-lumen catheter fixing device, which is actually a hemodialysis catheter sheath, and the device includes a sealed bag body, the bag body has a front side and a back side, the front side and the back side are sealed at the edges to form a sealed cavity, the front side of the bag body is provided with scale marks, the upper part of the back side of the bag body is provided with an opening, and the opening is used for receiving a catheter. After the guide pipe extending out of the human body is placed in the sealed bag body, the guide pipe is prevented from contacting with the outside, and the sterile environment is ensured, so that the sanitation and the safety are ensured. When the device is used, the conventional operation of rolling gauze into a cylinder is omitted; however, in hemodialysis, the whole device needs to be removed, and then the device is adhered back after the dialysis is finished, or a new device needs to be replaced and adhered back, so that the adhesive tape needs to be torn and adhered frequently, the operation is troublesome, and the patient is uncomfortable.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: provides a hemodialysis catheter sheath which is easy to operate when in use.

The technical scheme adopted for solving the problems is as follows: hemodialysis pipe sheath includes the sheath main part, still including hiding piece and flexible pad, and the sheath main part includes flexible cover, adapter sleeve and protecting cover, and the adapter sleeve is connected with the flexible cover rear end, and the protecting cover can be dismantled with the adapter sleeve and be connected, hides the piece and is located the flexible cover front end outside and is connected with the flexible cover, and the flexible pad is located protecting cover inboard and is connected with the flexible cover.

Further, the method comprises the following steps: the inner surface edges of the covering sheet and the flexible pad are provided with adhesive, and the adhesive is covered with a protective layer.

Further, the method comprises the following steps: the adhesive and the protective layer are intermittently arranged.

Further, the method comprises the following steps: the protecting cover is in threaded connection with the flexible sleeve.

Further, the method comprises the following steps: the cover sheet and the flexible pad are both made of gauze.

Further, the method comprises the following steps: the flexible sleeve is made of transparent flexible plastic.

Further, the method comprises the following steps: the flexible sleeve comprises a flexible sleeve inner layer made of gauze and a flexible sleeve outer layer made of transparent flexible plastic.

The utility model has the advantages that: 1. as shown in fig. 5, the sheath body is sleeved on the hemodialysis catheter, the joint and the flow stopping clamp at the rear end of the catheter are positioned in the protective cover, the covering sheet covers the position where the catheter enters the human body, and then the covering sheet and the flexible pad are adhered to the human body. During dialysis, only need pull down the protecting cover, the joint of pipe and only flow the clamp and expose promptly to can be connected with dialysis equipment and carry out hemodialysis, the dialysis is accomplished the back and only needs to adorn the protecting cover back can. Therefore, the utility model has the advantages of simple operation and no discomfort for patients due to tearing and pasting the adhesive tape, and does not need to be integrally disassembled and assembled back in the using process.

2. Because there is not whole dismouting when using, the utility model discloses usable time is longer.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 to 4: hemodialysis pipe sheath includes sheath main part 1, still includes and covers piece 2 and flexible pad 3, and sheath main part 1 includes flexible cover 11, adapter sleeve 12 and protecting cover 13, and adapter sleeve 12 is connected with 11 rear ends of flexible cover, and protecting cover 13 can be dismantled with adapter sleeve 12 and be connected, covers piece 2 and is located the 11 front end outsides of flexible cover and is connected with flexible cover 11, and flexible pad 3 is located protecting cover 13 inboard and is connected with flexible cover 11.

When in use, the sheath body 1 is sleeved on the hemodialysis catheter 5, the joint and the flow stopping clamp at the rear end of the catheter are positioned in the protective cover 13, the shielding sheet 2 covers the position where the catheter enters a human body, and then the shielding sheet 2 and the flexible pad 3 are adhered to the human body. During dialysis, only need pull down protecting cover 13, the joint of pipe and only flow clamp expose promptly to can be connected with dialysis equipment with the joint and carry out hemodialysis, only need after the dialysis is accomplished with protecting cover 13 dress back can.
