Description

Catheter safety fixer

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a pipe safety fixing ware.

Background

A catheter access needs to be established in advance before dialysis treatment of a patient, the tail end of the catheter access needs to be fixed after dialysis is finished, and the traditional bandaging and fixing method is clinically adopted at present, namely, an exposed catheter is wrapped by sterile gauze and then fixed in a wound mode by using paper adhesive tapes, and then the exposed catheter is fixed on the skin in a transverse mode by using three paper adhesive tapes. Different wrapping modes are needed for different types and different exposed lengths of dialysis catheters, the operation method is tedious, time-consuming and overlong, the tightness is not well controlled during wrapping, the catheters are easy to separate and are not attractive due to over-loose wrapping, and the catheters are easy to touch and open due to over-tight wrapping. In addition, the paper tape is too narrow and is not firmly adhered to the skin, so that the catheter is not firmly fixed, the risk of catheter slippage is easy to occur, and even allergy of a patient can be caused.

A prior art stationary bag arrangement for a peritoneal dialysis catheter as proposed in CN203169684U, said stationary bag arrangement comprising: the fixing bag is respectively connected with two fixing belts arranged at two ends of the fixing bag body; the fixing bag comprises a bag-shaped body and an upper cover, wherein one end of the upper cover is connected with the bag-shaped body, the bag-shaped body is used for placing the dialysis tube, and the upper cover is used for fixing the dialysis tube. The patient can be fixed (frenulum or bonding) in the belly through the fixed band according to the size of oneself with the fixed bag device that is used for peritoneal dialysis pipe, accomplishes peritoneal dialysis back, directly puts into the fixed bag with peritoneal dialysis pipe, plays fixed, save the effect. But the device does not set up bag internal fixation structure, and in the use, the skew of pipe angle can produce the friction with fixed bag, and the time leads to the pipe cap of pipe to drop easily for a long time to stifled pipe or hemorrhage phenomenon appear.

In the prior art, CN209422725U proposes a hemodialysis catheter variable fixing bag, which is suitable for hemodialysis patients using hemodialysis catheters as blood vessels, and includes hemodialysis long-term catheters and temporary catheters, belonging to disposable sterile articles. The catheter fixing bag comprises: the long application is used for fixing the upper end of the catheter bag and plays a role in fixing and sealing the catheter bag; the variable non-woven fabric bag is used for protecting the exposed catheter in a closed manner, and the non-woven fabric is soft and comfortable in texture and good in water resistance, so that discomfort caused by long-time contact with the skin can be avoided; the application paste adhered to the lower part of the fixed bag is adhered to the skin, and the exposed catheter is protected and fixed again. This fixed bag adopts applying ointment or plaster to fix with skin, uses for a long time and can lead to it to paste insecurely and then lead to the pipe fixed insecurely with skin, the phenomenon of the pipe slippage easily appears, still may lead to the patient to be allergic even.

In the prior art, a special treatment towel for hemodialysis catheters, as proposed in CN210785658U, solves the problem that the existing hemodialysis treatment towel cannot protect catheters, and comprises a treatment towel, wherein a first fixing bandage and a second fixing bandage are sewn at two ends of the treatment towel respectively, a binding belt is sewn in the middle of the treatment towel, a first winding ring is sewn at the other end of the first fixing bandage, a fixing belt is sewn on one side surface of the binding belt, a receiving belt is further wound on the outer side of the binding belt, a second winding ring is sewn at one end of the receiving belt, the treatment towel is fixed at a hemodialysis cannula by attaching a first sub-magic tape and a first main magic tape after the second fixing bandage is wound around the first winding ring sewn by the first fixing bandage, after a patient performs dialysis cannula, the receiving belt clamps a pipeline in the binding belt through the second winding ring, and then effectively fixes the cannula through the second main magic tape and the second sub-magic tape, preventing the occurrence of displacement. The adjustable range of the bandage of the treatment towel is small, and the bandage is inconvenient to use when the body type difference of patients is large.

Meanwhile, the tail end of the catheter of a patient using the intubation at present is arranged outside the body, so that the intubator is not beautiful, and is inconvenient to bathe and move. The tail end pipe head is blocked by the pipe cap and the clamp, if the pipe cap falls off and the clamp is accidentally opened, the phenomenon of pipe blockage or bleeding can occur, and even the life risk of a patient can be caused.

Furthermore, on the one hand, due to the differences in understanding to the person skilled in the art; on the other hand, since the inventor studied a lot of documents and patents when making the present invention, but the space did not list all details and contents in detail, however, this is by no means the present invention does not possess these prior art features, but on the contrary the present invention has possessed all features of the prior art, and the applicant reserves the right to increase the related prior art in the background art.
