Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and more specifically, to a dialysis tube fixing device for nephrology nursing. Background Art

[0002] There are millions of capillaries in each kidney of the human body, which can form millions of capillary balls, called glomeruli, whose function is to filter blood, excrete waste and excess water in the body, and transport them to the bladder for storage through the ureters. In the early stages of glomerular function loss, it is difficult for the human body to detect it. Even when only 20% of the normal glomerular function is lost, the human body can still maintain normal life. However, once the kidneys cannot work properly, the waste of human metabolism cannot be filtered and excreted, and it will accumulate in the body, causing renal failure.

[0003] There are two types of renal failure, acute renal failure and chronic renal failure. Acute renal failure can be treated by short-term dialysis while waiting for kidney recovery, while chronic renal failure is usually caused by direct kidney disease and requires dialysis or kidney transplantation to maintain life. Hemodialysis refers to the process of drawing the patient's blood out of the body. The blood and the dialysate in the dialyzer purify the patient's blood through diffusion, convection, adsorption and ultrafiltration principles to remove metabolic products in the body and correct water, electrolyte and acid-base balance.

[0004] During hemodialysis, two needles are inserted into the arm to allow blood to flow from one dialysis tube into the dialyzer, and then flow back into the body through another dialysis tube after filtration. When patients undergo long-term hemodialysis, bulges will appear on their arms, which are called aneurysms. This is a common phenomenon in fistulas of dialysis patients, and the main reason is poor proximal reflux or repeated fixed-point punctures.

[0005] It is common for patients with long-term hemodialysis to have thousands of needle punctures in their arms. Therefore, the same position is often punctured, including the bulge. As part of the dialysis tube, the infusion needle often has its needle handle suspended when puncturing the bulge. The current treatment method is to use tape to initially stick the needle handle to the arm, then use medical cotton balls to pad the bottom of the needle handle, and then use tape to stick the medical cotton balls to the skin from the bottom of the needle handle toward the infusion needle, and finally use several pieces of tape for final fixation.

[0006] When using the above method, the cotton ball will produce a large deformation when slightly exerted. Therefore, if the patient moves his arm or the needle handle is touched, the infusion needle will easily tilt up and cause damage to the blood vessels and bleeding, and re-puncture is necessary, affecting hemodialysis. Summary of the invention

[0007] The present invention provides a dialysis tube fixing device for nephrology nursing, and aims to solve the problem that: when a medical cotton ball is used to pad the bottom of a needle holding handle, the cotton ball will produce a large deformation when a slight force is applied. If the patient moves his arm or the needle holding handle is touched, the infusion needle is very likely to tilt up, causing damage to the blood vessels and bleeding.

[0013] In a preferred embodiment, a pressing assembly and a limiting assembly are provided inside the upper cavity, the pressing assembly is used to push the pressure rod downward so that the adhesive layer at the bottom of the pressure rod adheres to the skin, and the limiting assembly is used to limit the pressure rod.

[0014] In a preferred embodiment, the lower pressing assembly includes a lower pressing plate 1, which is fixedly connected to the outer side of the pressing rod, a side opening is opened on one side of the upper cavity, one end of the lower pressing plate 1 extends from the side opening to the outer side of the mounting frame, a guide column is vertically fixedly installed inside the upper cavity, the lower pressing plate 1 is vertically sleeved on the guide column, and an elastic component 1 is sleeved on the outer side of the guide column, and the two ends of the elastic component 1 are respectively pressed with the bottom of the upper cavity and the lower surface of the lower pressing plate 1.

At this time, the limiting part can press against the upper end of the pressure rod to limit the pressure rod, so that the pressure rod can no longer move upward, thereby allowing the adhesive layer to stably stick to the skin without being affected by the elasticity of the elastic component 1 and reducing the adhesion.

[0021] By setting the limiting component 2, when the lower pressing plate 1 is pressed down to tear off the release layer, the limiting column will not limit the pressing rod, and the pressing rod can be reset upward. When it is necessary to make the adhesive layer at the bottom of the pressing rod stick to the skin, the lower pressing plate 2 and the lower pressing plate 1 are pressed down at the same time. At this time, the limiting column can limit the pressing rod so that the pressing rod can no longer move upward. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Refer to the instruction manual Figure 1-Figure 8A dialysis tube fixing device for nephrology nursing includes a mounting frame 1, one side of the mounting frame 1 is provided with a connecting plate 11, a receiving bag 2 is fixedly installed on the side of the connecting plate 11 away from the mounting frame 1, the receiving bag 2 is used to wrap around the aneurysm 100 and to support the infusion needle; the interior of the receiving bag 2 is used to accommodate a hydraulic material, and a water injection port 12 is opened at the upper end of the mounting frame 1, and the water injection port 12 is connected to the interior of the receiving bag 2, so that water is injected into the interior of the receiving bag 2 through the water injection port 12 to mix the water with the hydraulic material.

[0033] Furthermore, the hydraulic material is gypsum powder, and after water is injected into the containing bag 2, the ratio of water to gypsum powder is 0.5-0.6.

[0034] It should be noted that the more gypsum powder is used, the faster it solidifies. When the ratio of water to gypsum powder is 0.5-0.6, the gypsum solidification time is about 6 minutes. In addition, in addition to gypsum powder, medical bone cement can also be used, but gypsum powder is more economical.

[0035] Furthermore, if Figure 2 and Figure 3 As shown, a socket 21 is fixedly connected to one side of the interior of the containing bag 2, and the socket 21 is communicated with the water injection port 12. A water port 22 is provided at one end of the socket 21 close to the interior of the containing bag 2. Water pipes 23 are fixedly connected to both sides of the socket 21. The two water pipes 23 extend to the two ends of the containing bag 2, and a one-way valve 3 is installed inside the water injection port 12 close to one end of the socket 21.

[0036] It should be noted that when water is injected into the containing bag 2 from the water injection port 12, the water flows from the water port 22 to the middle of the containing bag 2 through the one-way valve 3, and then flows from the two water pipes 23 to the two ends of the containing bag 2, thereby mixing with the gypsum powder in the containing bag 2. Through the setting of the one-way valve 3, after the water is injected, the water will no longer flow out of the containing bag 2, thereby preventing contamination of other medical devices; through the setting of the water port 22 and the water pipe 23, water can enter the middle and both ends of the containing bag 2, thereby accelerating the mixing of water and gypsum powder.

[0037] Furthermore, both ends of the containing bag 2 are fixedly connected with adhesive tapes 24 , and the bottom surface of the adhesive tapes 24 is adhered with release paper 25 .

[0038] In this embodiment, the implementation method is as follows: Figure 8As shown, the patient's arm 9 has an aneurysm 100. When an infusion needle is needed for puncture, first use a syringe to inject water into the interior of the bag 2 from the water injection port 12. After the water injection is completed, knead the bag 2 to fully mix the water and the gypsum powder. Then place the device at the edge of the aneurysm 100 and change the shape of the bag 2. The purpose is to use the bag 2 to support the needle handle 120 of the infusion needle. When changing the shape of the bag 2, the two ends of the bag 2 should wrap around the aneurysm 100, such as Figure 8 As shown, according to the position where the infusion needle is to be punctured, determine where the needle handle 120 will be located in the receiving bag 2, and adjust the position and height of the receiving bag 2 supporting the needle handle 120 by squeezing the receiving bag 2, tear off the release paper 25, and stick the adhesive tape 24 on the skin to fix the receiving bag 2. Wait for a while to allow the gypsum powder to initially solidify (the fluidity becomes worse, and there is no obvious deformation when lightly pressed). Then, as shown in FIG. Figure 8 As shown, the infusion needle 110 of the infusion needle is inserted into the blood vessel, the needle holding handle 120 of the infusion needle is placed on the surface of the receiving bag 2, and then fixed with medical tape.

[0039] In the above technical solution, a containing bag 2 is provided, a hydraulic material is provided in the containing bag 2, the hydraulic material is mixed with water before puncture, and the containing bag 2 is wrapped around the aneurysm 100 when the hydraulic material has not solidified. The containing bag 2 is squeezed, and the position and height of the containing bag 2 for supporting the needle holding handle 120 are adjusted. The needle holding handle 120 is supported by the containing bag 2 and will not be deformed after solidification. Even if the needle holding handle 120 is accidentally touched, the infusion needle 110 will not be lifted, thereby improving the safety during the dialysis process.

[0040] Refer to the instruction manual Figure 1-Figure 7 The fixing effect of sticking adhesive tapes 24 at both ends of the accommodation bag 2 is not strong, and if the adhesive position is directly set at the middle position of the bottom of the accommodation bag 2, the position will change because the accommodation bag 2 needs to be constantly adjusted when it is placed around the aneurysm 100, which is not conducive to gluing. Therefore, the following technical solution is proposed.

[0041] Specifically, a lower cavity 14 is opened at the bottom of the mounting frame 1, an upper cavity 13 is opened inside the mounting frame 1 at a position above the lower cavity 14, a pressure rod 4 is slidably connected inside the mounting frame 1, the upper end of the pressure rod 4 is located inside the upper cavity 13, and the lower end of the pressure rod 4 is located inside the lower cavity 14, and the bottom of the pressure rod 4 has an adhesive layer and is provided with a release layer 41.

[0042] Furthermore, a pressing assembly 5 and a limiting assembly are provided inside the upper cavity 13 . The pressing assembly 5 is used to push the pressing rod 4 to move downward so that the adhesive layer at the bottom of the pressing rod 4 adheres to the skin, and the limiting assembly is used to limit the pressing rod 4 .

[0043] Furthermore, the pressing assembly 5 includes a pressing plate 51, which is fixedly connected to the outer side of the pressing rod 4. A side opening 15 is provided on one side of the upper cavity 13. One end of the pressing plate 51 extends from the side opening 15 to the outer side of the mounting frame 1. A guide column 52 is vertically fixedly installed inside the upper cavity 13. The pressing plate 51 is vertically sleeved on the guide column 52. An elastic component 53 is sleeved on the outer side of the guide column 52. The two ends of the elastic component 53 are respectively pressed against the bottom of the upper cavity 13 and the lower surface of the pressing plate 51.

[0044] It should be noted that before using the receiving bag 2, the release layer 41 is torn off, and after adjusting the position and shape of the receiving bag 2, the lower pressing plate 1 51 can be pressed downward, and the lower pressing plate 1 51 drives the pressing rod 4 to move downward, so that the adhesive layer at the bottom of the pressing rod 4 adheres to the skin, thereby completing the adhesion and fixation of the receiving bag 2. Among them, the elastic component 1 53 is a compression spring.

[0045] In this embodiment, if Figure 3-Figure 6 As shown, the limit assembly is a limit assembly 6, which includes two spring sheets 61. The upper ends of the two spring sheets 61 are fixedly connected to the mounting frame 1, and the bottom of the spring sheet 61 is a limit portion 62. The limit portion 62 is a free end. The limit portion 62 is used to press on the upper end of the pressure rod 4 to limit the pressure rod 4 from moving upward. The two spring sheets 61 have steps 63 on the opposite sides, and a pressure plate 64 is pressed between the two steps 63. The upper end of the pressure rod 4 is used to push the pressure plate 64 upward to separate the pressure plate 64 from the two steps 63.

[0046] It should be noted that, in the unused state, the pressing plate 64 is pressed at the position of the two steps 63, so that the two spring sheets 61 are deformed to both sides. Before placing the accommodation bag 2 around the aneurysm 100, the release layer 41 needs to be torn off. At this time, the lower pressing plate 1 51 is pressed down, and the lower pressing plate 1 51 drives the bottom of the pressure rod 4 to move out of the lower cavity 14. At this time, the release layer 41 can be torn off. When the lower pressing plate 1 51 is released, the lower pressing plate 1 51 is reset upward under the action of the elastic component 1 53, and the bottom of the pressure rod 4 moves back to the inside of the lower cavity 14. The purpose is that when the position and shape of the accommodation bag 2 are adjusted, the adhesive layer will not stick to the skin. When the position and shape of the accommodating bag 2 are adjusted, the lower pressure plate 51 is first pushed upward to make the upper end of the pressure rod 4 push the pressure plate 64 upward. The pressure plate 64 moves upward and disengages from the two steps 63. At this time, the two spring pieces 61 recover their deformation toward the middle, and then the lower pressure plate 51 is pushed downward again. The lower pressure plate 51 drives the pressure rod 4 so that the adhesive layer at the bottom of the pressure rod 4 sticks to the skin. At this time, the upper end of the pressure rod 4 moves to the bottom of the spring piece 61, and the limiting portion 62 presses on the upper end of the pressure rod 4. The pressure rod 4 can no longer be pushed upward by the elastic component 53.

[0047] The above technical solution sets a limit component 6. When the lower pressure plate 51 is pressed to tear off the release layer 41, the limit part 62 will not limit the pressure rod 4, and the pressure rod 4 can be reset upward, so that when the position and shape of the accommodating bag 2 are adjusted, the adhesive layer will not stick to the skin; when the adhesive layer needs to stick to the skin, the pressure plate 64 is first pushed upward to reset the spring piece 61, and then the lower pressure plate 51 is pushed downward. At this time, the limit part 62 can be pressed against the upper end of the pressure rod 4 to limit the pressure rod 4, so that the pressure rod 4 can no longer move upward, so that the adhesive layer can be stably adhered to the skin, and the adhesive force will not be reduced due to the elasticity of the elastic component 53.

[0048] In this embodiment, another structure of the limit assembly is provided, specifically, as Figure 7 As shown, the limit component is the limit component 2 7, the top of the upper cavity 13 is provided with a socket 16, and side holes 17 are provided on both sides of the bottom of the socket 16. The limit component 2 7 includes a limit column 71, and the limit column 71 is vertically movably inserted into the inside of the socket 16. Both sides of the upper end of the limit column 71 are provided with clamping columns 72, and an elastic component 2 73 is pressed between the two clamping columns 72. A lower pressure plate 2 74 is fixedly connected to one side of the bottom of the limit column 71, and the lower pressure plate 2 74 extends from the side opening 15 to the outside of the mounting frame 1.

[0049] It should be noted that, in the unused state, the lower end of the limiting column 71 is in contact with the upper end of the pressure rod 4, and the clamping column 72 is located above the side hole 17. Before placing the accommodation bag 2 around the aneurysm 100, the release layer 41 needs to be torn off. At this time, the lower pressing plate 51 is pressed down, and the lower pressing plate 51 drives the bottom of the pressure rod 4 to move out of the lower cavity 14. When the lower pressing plate 51 is released, the lower pressing plate 51 is reset upward under the action of the elastic component 53, and the bottom of the pressure rod 4 moves back to the inside of the lower cavity 14. When the position and shape of the accommodating bag 2 are adjusted, the lower pressure plate 2 74 and the lower pressure plate 1 51 are pushed downward at the same time, and the lower pressure plate 1 51 drives the pressure rod 4 so that the adhesive layer at the bottom of the pressure rod 4 sticks to the skin. At this time, the lower pressure plate 2 74 also drives the limiting column 71 to move downward, and under the action of the elastic component 2 73, the clamping column 72 is clamped into the side hole 17, so that the limiting column 71 can no longer move, and the limiting column 71 is fitted together with the limiting component 2 7, and the pressure rod 4 can no longer move upward, wherein the elastic component 2 73 is a compression spring.

[0050] The above technical solution is provided with a limit assembly 2 7. When the lower pressing plate 1 51 is pressed down to tear off the release layer 41, the limit column 71 will not limit the pressing rod 4, and the pressing rod 4 can be reset upward. When it is necessary to make the adhesive layer at the bottom of the pressing rod 4 stick to the skin, the lower pressing plate 2 74 and the lower pressing plate 1 51 are pressed down at the same time. At this time, the limit column 71 can limit the pressing rod 4 so that the pressing rod 4 can no longer move upward.

[0051] Furthermore, a handle 8 is hinged at one end of the lower pressure plate 51 away from the mounting frame 1, and the length of the lower pressure plate 2 74 extending outside the mounting frame 1 is smaller than the length of the lower pressure plate 51 extending outside the mounting frame 1. When the handle 8 is rotated in the direction of the lower pressure plate 2 74, the handle 8 presses on the upper surface of the lower pressure plate 2 74.

[0052] It should be noted that when only the lower pressure plate 51 is pushed downward, the handle 8 can be directly pressed down. When it is necessary to push the lower pressure plate 51 and the lower pressure plate 2 74 downward at the same time, the handle 8 can be rotated in the direction of the lower pressure plate 2 74 so that the handle 8 is pressed on the lower pressure plate 2 74. Then, the handle 8 can be pressed down to push the lower pressure plate 51 and the lower pressure plate 2 74 downward at the same time.

[0053] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
