Description

TECHNICAL FIELD

[0001] The utility model relates to medical appliance field, concretely relates to a dialysis puncture needle fixing device. BACKGROUND

[0002] In the modern medical field, hemodialysis is an important treatment method for helping patients with kidney failure and the like to maintain life. The dialysis puncture needle plays a key role in the whole dialysis process. The dialysis puncture needle is generally composed of a needle tube, a needle seat, a protective sleeve, an infusion tube and the like. The infusion tube is usually relatively thick to ensure sufficient blood flow during dialysis. When blood dialysis is performed, two blood paths are established, one of which leads the blood in the patient's body out of the body and is transported to the dialysis machine. The blood is filtered, purified and the like in the dialysis machine to remove metabolic waste and excess water in the body. The other tube returns the cleaned blood after dialysis to the patient's body to maintain normal blood circulation and physiological functions of the body.

[0003] If the patient has an arteriovenous fistula, the puncture is usually performed on the arm with the fistula, and both puncture needles are on the arm, one of which connects the arterial end to lead the blood out of the body, and the other of which connects the venous end to return the purified blood.

[0004] With the continuous development of medical technology, the fixing requirements for the dialysis puncture needle are also increasing. In the early stage, the fixing method of the dialysis puncture needle was relatively simple, usually only relying on medical tape for pasting and fixing. However, this fixing method has many disadvantages. On the one hand, the adhesion of the medical tape is limited, and the thick needle tube for dialysis is prone to looseness or even falling off during patient activity or dialysis. Once the puncture needle loosens or falls off, not only will the dialysis treatment be interrupted, affecting the treatment effect, but also may cause the patient to bleed, seriously threatening the life safety of the patient.

[0005] On the other hand, the skin conditions of different patients are different, some patients may be allergic to the tape, causing skin redness, itching and other adverse reactions, bringing additional pain to the patient. Moreover, frequent replacement of the tape will also increase the work burden of medical staff and waste medical resources.

[0006] In addition, the conventional fixing mode is difficult to ensure the angle stability of the puncture needle. In the dialysis process, a slight change in the angle of the puncture needle can affect the blood flow, thereby affecting the dialysis effect. At the same time, improper fixation can also cause uneven pressure on the puncture site, increase the discomfort of the patient, and even cause local tissue damage. The existing fixing mode, for example, the dialysis tube positioning restraint belt for nephrology department disclosed in the publication No. CN214911388U and the publication date is November 30, 2021, the inner wall of the restraint belt is movably connected with a sponge pad, the right end of the restraint belt is fixedly connected with an insert piece, the left end of the restraint belt is provided with an insert slot, the insert piece is inserted into the insert slot, the lower surface of the insert piece is provided with an engagement groove, one side of the insert slot is provided with an engagement tooth, the engagement tooth is engaged with the engagement groove, the middle part of the engagement tooth is hingedly connected with the restraint belt, and the bottom of the engagement tooth is fixedly connected with a compression spring. The utility model discloses a restraint belt, when the dialysis tube is installed, the restraint belt is wound around the arm, the dialysis tube is sleeved in the restraint belt, the dialysis tube is clamped in the semicircular groove on the inner wall of the restraint belt, then the insert piece is inserted into the insert slot, the engagement groove is clamped with the engagement tooth, and the installation is completed, so that the dialysis tube can be fixed. The overall fixing device is complex, the use cost is high, and the failure is easy. Utility model content

[0028] The technical solutions in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments, not all the embodiments.

[0029] In the description of the utility model, it needs to be understood that the terms "front", "back", "left", "right", "up", "down", "top", "bottom", "inner", "outer" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model.

[0030] Reference Figures 1-5 The utility model provides a kind of dialysis puncture needle fixing device, it is mainly composed of restraint belt 10 and clamping interface 20, restraint belt 10 both ends are equipped with adhesive part 11.

[0031] In specific implementation, restraint belt 10 adopts medical polyester fiber material. It is soft in texture, can be closely attached to patient's arm, brings comfortable feeling, especially suitable for patient who can have allergic reaction to silicone and glue and the like. The surface of this material is smooth, liquid is not easy to adhere, it is extremely convenient to clean, even if there is a small amount of stain, it can be removed by gently wiping with wet cloth, which greatly reduces the cleaning difficulty and time cost, so that the device can be reused.

[0032] In specific implementation, clamping interface 20 is in two groups, first clamping interface 21 is arranged on one side of restraint belt 10, and second clamping interface 22 is arranged on the other side of restraint belt 10. Clamping interface 20 is designed as a groove, and when two grooves are embedded and clamped, dialysis puncture needle can be fixed firmly. The width of first clamping interface 21 and second clamping interface 22 is half of the width of restraint belt 10, and when the width of restraint belt 10 is 2 centimeters, the width of clamping interface 20 is 1 centimeter. Such design not only ensures the rationality of the layout of clamping interface 20 on restraint belt 10, but also ensures that the width of restraint belt 10 will not increase when two clamping interfaces 20 are embedded and clamped together, avoiding that the whole device is too bulky to hinder treatment.

[0033] In specific implementation, the edge of clamping interface 20 is thickened to increase its hardness, which can provide stable supporting force and ensure that it will not be easily deformed when fixing dialysis puncture needle. At the same time, the thickened edge makes clamping more stable, which can effectively prevent the sliding of puncture needle after being fixed.

[0034] In specific implementation, the distance between the first and second clamping interfaces 21 and 22 is the circumference of the dialysis puncture needle infusion tube. Taking a common dialysis puncture needle infusion tube with a diameter of 0.8 cm as an example, according to the circumference formula of a circle C = πd (C is the circumference, d is the diameter, and π is 3.14), the circumference of the infusion tube is about 2.512 cm. Therefore, the distance between the clamping interfaces 20 is set to about 2.5 cm, which can ensure that the infusion tube of the puncture needle can be tightly fixed in the clamping interface 20 and will not loosen or slip off.

[0035] In specific implementation, the restraint belt 10 is used to fix one side of the puncture needle infusion tube, and a convex structure is formed on the inner surface thereof through a special processing process. These textures and convexes can increase the friction between the restraint belt 10 and the infusion tube, effectively preventing the infusion tube from moving in the restraint belt 10.

[0036] In specific implementation, the adhesive part 11 of the restraint belt 10 adopts a magic tape, which is divided into a hook surface and a fuzzy surface and is oppositely arranged on the upper surface and the lower surface. The hook surface adopts a small and tough hook structure, and the fuzzy surface is made of soft fiber material. The length of the magic tape is reasonably designed according to the length of the restraint belt 10 to ensure that it can meet the use of patients with different arm thicknesses. For example, for adult arms, the length of the restraint belt 10 can be designed to be about 30 cm, and the length of the magic tape is 10 cm. In this way, during use, the actual thickness of the patient's arm can be flexibly adjusted to ensure the firmness of the fixing device

[0037] In specific operation, when fixing a single infusion tube, first, the dialysis puncture needle is inserted into the appropriate position of the patient's arm, and then the infusion tube is arranged to keep it in a natural state to avoid excessive bending or twisting. Then, the restraint belt 10 is taken, the side with the convex structure is placed towards the infusion tube, the infusion tube is placed between the two clamping interfaces 20, and it is ensured that it is parallel to the width direction of the restraint belt 10, and then it is wound. Subsequently, the first and second clamping interfaces 21 and 22 are clamped, and after the clamping is determined to be stable, the restraint belt 10 is wrapped around the patient's arm, so that the magic tapes at both ends can contact each other. Finally, according to the thickness of the patient's arm, the position of the restraint belt 10 is adjusted to ensure that the infusion tube is in the appropriate position and will not loosen or slip off.

[0038] When fixing two infusion tubes (which is suitable for patients with arteriovenous fistula), the steps are the same as those for fixing a single infusion tube. The two infusion tubes are arranged and placed between each set of clamping interfaces 20, respectively, and then wound and clamped to keep a certain distance between the two infusion tubes to avoid mutual entanglement. Then, the position of the restraint belt 10 is adjusted to ensure that the two infusion tubes are in the appropriate position and the patient's arm is comfortable, and the magic tapes at both ends can contact each other to be fixed.

[0039] When the position that needs to be fixed, such as needle seat, cannot be fixed by winding, the side with the convex structure can be directly wound towards the position that needs to be fixed and the arm, and finally fixed by magic tape at both ends.

[0040] The preferred embodiments of the present application are described above, but the present application is not limited to the above, and various modifications and changes can be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
