Problems solved by technology

[0003] In the prior art, the fixing equipment of the hemodialysis catheter is mostly designed according to the fixed position, so that the hemodialysis catheter can only be fixed at the corresponding position, and the placement position of the hemodialysis catheter can be placed in the internal jugular vein, femoral vein, etc. according to the actual situation. It is difficult to fix the corresponding position according to the actual needs of the hemodialysis catheter fixing device designed specifically for a certain position, which causes inconvenience to the medical staff; after the hemodialysis catheter is connected to the patient's body surface, The hemodialysis catheter is likely to be squeezed and deformed due to the patient's physical activities, and the internal space for material circulation is reduced, which has an adverse effect on the flow rate of the dialysate in the hemodialysis operation, and the hemodialysis catheter is easily exposed to the external environment. The patient's negligence caused the hemodialysis catheter to be damaged and ruptured, making it easy for external dirt to enter the patient's body from the ruptured position of the hemodialysis catheter, affecting the patient's health; The frictional force between the body surfaces is large and the position will not move due to sliding, so that the contact surface between the connecting belt of the fixed device and the patient's body surface is large. When the external ambient temperature is high, the air circulation in the area covered by the connecting belt Not smooth, and the heat generated by itself is difficult to dissipate due to the coverage of the connecting belt, which is easy to cause discomfort to the patient

Embodiment 1

[0040] see Figure 1-5 As shown, a children's hemodialysis catheter fixing device includes a dialysis tube bifurcation block 1 and a venoarterial tube 3, and both sides of the front surface of the dialysis tube bifurcation block 1 are connected with a venoarterial tube 3;

[0041] One side of the outer wall of the dialysis tube bifurcation block 1 is provided with a connecting mechanism 2, and the connecting mechanism 2 includes a storage box 23, and one side of the outer wall of the storage box 23 is connected with a rubber band 21, and the width of the rubber band 21 is smaller than the width of the storage box 23 , so that the rubber band 21 can be stored in the inside of the storage box 23 in a roll shape, and the middle position of the rear surface of the storage box 23 is rotatably connected with a support shaft 213, and one end of the rubber band 21 is connected to the outer side wall of the support shaft 213, so that The support shaft 213 can roll up the rubber band 21...

Embodiment 2

[0047] see Figure 6-7As shown, the front surface of the storage box 23 is provided with a protective mechanism 4, the protective mechanism 4 includes a second support plate 42, the four corners of the outer wall of the second support plate 42 are connected with limit rods 43, and the four limit rods 43 are movable. The activity of plate 47 is restricted, and movable plate 47 is kept level with second support plate 42 all the time in the process of moving position, and second support plate 42 center position is rotationally connected with second screw rod 44, and the outer wall of second screw rod 44 slides A movable plate 47 is connected, and the movable plate 47 slides on the second screw rod 44 through the sliding part inside. The second screw rod 44 is connected with a second gear 45 near the end of the interlocking chamber 210, and the front surface of the interlocking chamber 210 corresponds to the first gear. A screw rod 28 is connected to a first gear 46 through a conn...

Embodiment 3

[0052] see Figure 8-10 As shown, the outer wall of the second support plate 42 is provided with an anti-sweat mechanism 5, and the anti-sweat mechanism 5 includes a second connecting pipe 54, and a second telescopic hose is connected to the position corresponding to the second connecting pipe 54 on the outer wall of the second supporting plate 42. 51, the other end of the second telescopic hose 51 is connected to the movable plate 47, and can shrink and stretch following the reciprocating motion of the movable plate 47 on the second screw 44, so that the second telescopic hose 51 can stretch The outside air is transmitted to the inside of the connecting pipe 55 through the second connecting pipe 54, and flows from the inside of the connecting pipe 55 to the inside of each air bag 52. There are several air bags 52 evenly distributed on one side of the outer wall of the rubber band 21, and the outer side of the rubber band 21 The other side of the wall is connected with a conne...

Abstract

The invention relates to the technical field of hemodialysis catheters, in particular to a fixing device for a catheter used in hemodialysis of a child. The invention aims to solve the problems that the fixing position of fixing equipment of a hemodialysis catheter is limited, a hemodialysis catheter is prone to deformation after being fixed, dialysate transmission is affected, and discomfort is easily caused due to the fact that the covering area of a connecting belt is large in the prior art. The fixing device for the catheter used in hemodialysis of the child comprises a dialysis tube bifurcation block and static artery tubes, wherein the static artery tubes are connected to the two sides of the front surface of the dialysis tube bifurcation block, and a connecting mechanism is arranged on one side of the outer side wall of the dialysis tube bifurcation block. According to the fixing device, after being tightened, a rubber band belt is driven by a supporting frame to be tightened again to fix a position, so the hemodialysis catheter can be fixed to a certain position without being limited by the hemodialysis catheter fixing device; length adjustment is conducted through a telescopic sleeve under ventilation control to protect the hemodialysis catheter, so the hemodialysis catheter is prevented from being damaged; and heat dissipation of a area covered by the rubber band is not affected by air generated after an air bag on the rubber band expands.

Description

technical field [0001] The invention relates to hemodialysis catheter technology, in particular to a children's hemodialysis catheter fixing device. Background technique [0002] Hemodialysis refers to the drainage of blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers. The principle of convection is to exchange substances, remove metabolic wastes in the body, maintain electrolyte and acid-base balance, remove excess water in the body at the same time, and return the purified blood to the process. [0003] In the prior art, the fixing equipment of the hemodialysis catheter is mostly designed according to the fixed position, so that the hemodialysis catheter can only be fixed at the corresponding position, and the placement position of the hemodialysis catheter can be placed in the internal jugular vein, femoral vein, etc. according to the actual situation. It is difficult to fix the corresponding position according to the ac...
