[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 6 As shown, an embodiment of the utility model provides a medical catheter pressure protection device, comprising: a support plate 1, the cross-section of the support plate 1 is semicircular, and the inner diameter of the support plate 1 is larger than the outer diameter of the catheter, a pair of force unloading plates 2, respectively fixedly installed on both sides of the support plate 1, for sharing the pressure exerted on the support plate 1, a dressing 3, arranged between the force unloading plate 2 and the patient's skin, for protecting the support plate 1 and the skin below the force unloading plate 2, and a corresponding number of clamping members as the force unloading plate 2, which are arranged on a side of the pair of force unloading plates 2 away from the support plate 1, for locking the dressing 3 relative to the force unloading plate 2.

[0027] The working principle and beneficial effects of the above technical solution are as follows: first, the dressing 3 is placed below the wound on the back of the patient when the patient is standing, and the position of the catheter is adjusted to be placed in the middle of the upper surface of the dressing. Then, the plate body of the device is covered above the dressing, and the tube body part of the catheter placed under the abdominal belt is embedded under the support plate 1. After adjusting the position of the plate body of the force unloading plate 2, the two sides of the dressing 3 that are not pressed by the plate body are turned up, and the clamping piece is moved to clamp the dressing 3 in cooperation with the edge of the force unloading plate 2, and a medical tape is affixed to the everted part for fixing. At this time, the part of the catheter originally pressed by the abdominal belt is protected by the dressing 3 and the support plate 1 and will not be compressed, and the abdominal belt can be worn again. This embodiment adopts the technical means of cooperating with the support plate 1 and the force unloading plate 2. There is no need to pass the catheter through the gap of the abdominal belt. It is only necessary to prevent various catheters including the drainage tube from being compressed by the support plate 1. The force unloading plate 2 shares the pressure on the support plate 1 after wearing the abdominal belt. To a certain extent, the deficiencies in the prior art are overcome, thereby eliminating the corresponding safety hazards.

[0028] In one embodiment, the clamping member includes a pair of rotating shafts 4 , each rotating shaft 4 is rotatably connected to a corresponding unloading plate 2 , and one end of the rotating shaft 4 extending outside the unloading plate 2 is fixedly connected to a clamping plate 5 .

[0029] The working principle and beneficial effects of the above technical solution are as follows: except for the dressing 3 which is a disposable consumable, the rest of the device can be reused. When in use, the two sides of the dressing 3 that are not pressed by the force unloading plate 2 are flipped up, and then the two clamps 5 are rotated to press the dressing, so that the dressing can be fixed relative to the force unloading plate 2, and then the flipped edges of the dressing 3 are turned back, and medical tape is pasted on it for further fixation. The entire device can be fixed near the patient's wound without sticking to the force unloading plate 2, so as to avoid the colloid on the tape from adhering to the force unloading plate 2, thereby reducing the difficulty of cleaning. The dressing 3 is a disposable consumable and can be discarded after use.

[0030] In one embodiment: an embedded rod 6 is fixedly connected to the upper surface of each clamping plate 5 away from the rotating shaft 4, and a U-shaped clamp 7 is fixedly connected to the upper surface of the force unloading plate 2, and the positions of the embedded rod 6 and the U-shaped clamp 7 correspond to each other.

[0031] The working principle and beneficial effects of the above technical solution are as follows: when the splint 5 rotates to a position almost parallel to the unloading plate 2, the embedded rod 6 contacts and squeezes the corresponding U-shaped clip 7 until it is embedded in the elastic U-shaped clip 7, and the splint 5 just moves to a state parallel to the unloading plate 2, clamping the dressing 3.

[0032] In one embodiment: a moving tube 8 is sleeved on one end of each rotating shaft 4 close to the supporting plate 1, a spiral groove 9 is opened on the moving tube 8, an extrusion rod 10 is fixedly connected to each rotating shaft 4, and the extrusion rod 10 is passed through the corresponding spiral groove 9, a connecting plate 11 is fixedly connected to one end of the two moving tubes 8 close to each other, a guide groove 12 for the connecting plate 11 to move is opened on the unloading plate 2, and a clamping block 13 is fixedly connected to one end of each connecting plate 11 away from the moving tube 8.

[0033] The working principle and beneficial effects of the above technical solution are as follows: the rotation of the rotating shaft 4 drives the extrusion rod 10 thereon to rotate synchronously, the extrusion rod 10 squeezes the corresponding spiral groove, and the guide groove 12 restricts the moving trajectory of the connecting plate 11, so that the two moving tubes 8 approach or move away from each other, and with the cooperation of the connecting plate 11, the two clamping blocks 13 approach or move away synchronously.

[0034] In a specific embodiment, each clamping block 13 is configured to be semicircular and is made of rubber.

[0035] The working principle and beneficial effects of the above technical solution are as follows: the semi-circular clamping block 13 can better fit the outer surface of the catheter, and while tightly clamping it, it does not cause excessive deformation to ensure the normal flow of the liquid therein, and at the same time, setting it to rubber material can increase the friction between it and the catheter, further improving its clamping effect.

[0036] In one embodiment, a side of each clamping plate 5 away from the force unloading plate 2 is subjected to arc transition treatment.

[0037] The working principle and beneficial effects of the above technical solution are as follows: by making one side of the splint 5 into an arc transition, a gap can be formed between the splint 5 and the skin, and when removing the device, the splint can be lifted up quickly and conveniently.

[0038] In one embodiment, each unloading plate 2 is provided with a plurality of heat dissipation holes 14 which are arranged at equal distances.

[0039] The working principle and beneficial effects of the above technical solution are as follows: the provision of the heat dissipation holes 14 can enhance air convection in the gap between the cooperation plate 2 and the skin, avoid sweating, and reduce the weight of the device.

[0040] Working principle and usage process:

[0041] First, place the dressing 3 under the wound on the patient's back when the patient is standing, and adjust the position of the catheter to place it in the middle of the upper surface of the dressing 3. Then, cover the dressing 3 with the plate part of the device, place one end of the clamping block 13 close to the wound, and clamp the catheter at the wound between the two clamping blocks 13. The catheter body part under the abdominal belt is embedded under the support plate 1. After adjusting the position of the force unloading plate 2, turn up the two sides of the dressing 3 that are not pressed by the plate, and then rotate the two clamping plates 5 to press the dressing, fix it by buckling the embedded rod 6 and the U-shaped clamp 7, and then turn the dressing 3 outward, and stick the medical mask on the everted part. It is fixed with adhesive tape, and the two clamping blocks 13 are driven to approach each other during the rotation of the rotating rod, and the catheter tube body at the wound position is tightly clamped to effectively prevent it from shaking. Finally, the abdominal belt is worn, and the belt body located on the back presses the entire device downward, and the catheter is led out from the bottom of the device without being subjected to force. The pressure of the abdominal belt on the device is distributed at various positions of the device, and the dressing can absorb sweat and buffer, which can effectively reduce the possibility of indentation. The heat dissipation holes can improve the heat dissipation effect and avoid sweating. At the same time, the embedded rod 6 and the U-shaped clip 7 that are more prominent relative to the main body of the device can increase the friction between the abdominal belt and the abdominal belt, thereby further improving the stability of the device.
