Description

Technical Field

[0001] This utility model relates to the technical field of compression hemostasis devices, and more specifically to a compression hemostasis device after PICC catheterization. Background Technology

[0002] PICC placement is a central venous catheter inserted through a peripheral vein. It is mainly used for cancer patients who require long-term chemotherapy and is suitable for patients who need long-term infusion, chemotherapy, and nutritional support. The catheter is usually placed in the arm.

[0003] After catheter placement, bleeding may occur at the puncture site. In current technology, hemostasis is generally achieved by applying pressure. The principle is to apply external force to the puncture site to artificially block the bleeding and prevent it from continuing to flow out. After a few minutes, the blood that has flowed out will naturally coagulate. At this point, the pressure will be released and the blood will no longer flow out.

[0004] In practice, doctors or patients usually use gauze, cotton balls or other tools to manually press the puncture site to stop the bleeding. To make it more convenient, hemostatic devices that do not require continuous manual pressure have also emerged, such as a PICC catheter insertion bleeding compression hemostatic device with publication number CN217285951U.

[0005] However, when using pressure to stop bleeding, it is important to pay attention to the force and duration. Insufficient force and short duration will result in poor hemostasis, while excessive force and long duration will lead to poor blood flow at the puncture site, causing discomfort to the patient. The existing pressure hemostasis methods cannot flexibly adjust the force and duration of pressure, resulting in poor effectiveness. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a PICC insertion compression hemostasis device. By gradually reducing the compression force as the blood at the puncture site gradually coagulates during the compression hemostasis process, the device avoids poor blood flow at the puncture site due to prolonged excessive force, thereby improving patient comfort and the effectiveness of the compression hemostasis device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a PICC insertion compression hemostasis device, comprising a U-shaped frame, the U-shaped frame comprising a vertical section and upper and lower horizontal sections, for a total of three sections, an adapter tube fixedly provided on the upper horizontal section of the U-shaped frame, the adapter tube penetrating the upper horizontal section;

[0008] The top of the adapter tube is provided with a detachable cover plate, and a miniature vent tube communicating with the inside of the adapter tube is fixed on the cover plate. An elastic membrane is fixed at the bottom of the adapter tube, and a pressing structure is provided at the bottom of the elastic membrane. A transparent pressurizing cylinder for supplying air to the inside of the adapter tube is provided on one side of the adapter tube.

[0009] Furthermore, the pressing structure includes a pressure plate located at the bottom of the elastic membrane, and a plurality of telescopic rods are fixedly provided at the top of the pressure plate. The telescopic rods are distributed on the outside of the adapter cylinder, and the top of the telescopic rods are fixedly connected to the upper horizontal section of the U-shaped frame.

[0010] Furthermore, an installation groove is provided on the upper horizontal section of the U-shaped frame, and the transparent pressure cylinder is fixedly installed on the inner wall of the installation groove. The surface of the transparent pressure cylinder is provided with graduations.

[0011] The transparent pressure cylinder has a movable plug inside, the outer end of which contacts the inner wall of the transparent pressure cylinder. A spring is fixedly installed on the side of the movable plug away from the adapter cylinder, and an annular protrusion is fixedly installed on the end of the spring away from the movable plug. The annular protrusion is installed on the inner wall of the transparent pressure cylinder.

[0012] Furthermore, a connecting pipe is provided between the transparent pressure cylinder and the adapter cylinder. The two ends of the connecting pipe are fixedly connected to the transparent pressure cylinder and the adapter cylinder respectively and communicate with both of them. A ventilation hose is provided on the side of the moving plug away from the adapter cylinder. The two ends of the ventilation hose are located inside and outside the transparent pressure cylinder respectively.

[0013] Furthermore, both ends of the ventilation hose are fixedly provided with rigid end tubes. The rigid end tube inside the transparent pressure cylinder passes through the movable plug, and the rigid end tube outside the transparent pressure cylinder is fixedly provided with a one-way valve. Two finger rings are fixedly provided at the outer end of the rigid end tube outside the transparent pressure cylinder.

[0014] Furthermore, a support assembly is provided at the top of the lower horizontal section of the U-shaped frame. The support assembly is located directly below the adapter cylinder. The support assembly includes a pad block fixedly installed at the top of the lower horizontal section of the U-shaped frame. A lifting sleeve is threaded onto the top of the pad block, and a soft pad is fixedly installed on the top of the lifting sleeve.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model supplies air to the adapter tube through a transparent pressure cylinder, which generates high pressure inside the adapter tube. The air pressure causes the elastic membrane to expand and push the pressure plate to compress the puncture site for hemostasis. During this process, the air in the adapter tube slowly leaks through the micro ventilation tube, so that the air pressure and the pressure force gradually decrease. In this way, the pressure force can be gradually reduced as the blood at the puncture site gradually coagulates during the compression hemostasis process, avoiding poor blood flow at the puncture site due to prolonged excessive pressure, improving patient comfort, and also improving the effectiveness of the compression hemostasis device.

[0017] 2. The air intake inside the transparent pressure cylinder is controlled by adjusting the position of the movable plug, thereby adjusting the compression hemostasis time as needed. Once the set time is up, the air in the transparent pressure cylinder will be completely expelled, and the compression hemostasis will stop immediately, avoiding excessive compression hemostasis time that could cause poor blood flow.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Refer to the instruction manual appendix Figure 1 -Appendix Figure 6 This utility model provides a PICC insertion compression hemostasis device, including a U-shaped frame 1. The U-shaped frame 1 includes a vertical section and two horizontal sections, upper and lower, for a total of three sections. An adapter tube 3 is fixedly provided on the upper horizontal section of the U-shaped frame 1, and the adapter tube 3 passes through the upper horizontal section.

[0027] The top of the adapter tube 3 is provided with a detachable cover plate 303, and a miniature vent tube 301 communicating with the inside of the adapter tube 3 is fixed on the cover plate 303. An elastic membrane 302 is fixed at the bottom of the adapter tube 3, and a pressing structure is provided at the bottom of the elastic membrane 302. A transparent pressurizing cylinder 2 for supplying air to the inside of the adapter tube 3 is provided on one side of the adapter tube 3.

[0028] The U-shaped frame 1 is placed on the patient's arm, and the pressure structure is aligned with the puncture site. Then, air is supplied into the adapter tube 3 through the transparent pressure tube 2. After the air enters the adapter tube 3, it generates high pressure. The air pressure causes the elastic membrane 302 to bulge downward and squeeze the pressure structure. The pressure structure thus presses downward on the puncture site, thereby achieving hemostasis. At the same time, the air that has entered the adapter tube 3 slowly leaks out through the micro ventilation tube 301. Therefore, during the compression hemostasis process, as the gas leaks out, the air pressure gradually decreases until the air pressure inside the adapter tube 3 is equal to the external air pressure, at which point the compression hemostasis is stopped.

[0029] This allows the pressure to gradually decrease as the blood at the puncture site coagulates during the compression hemostasis process, preventing poor blood flow due to prolonged excessive pressure at the puncture site. This improves patient comfort and the effectiveness of the compression hemostasis device. Furthermore, as the blood coagulates during compression, the required pressure gradually decreases, so the reduction in pressure does not affect the hemostatic effect.

[0030] In order to apply pressure directly to the puncture site, such as Figure 1 , Figure 2 As shown, the pressing structure includes a pressure plate 4 located at the bottom of the elastic membrane 302. A plurality of telescopic rods 5 are fixedly provided at the top of the pressure plate 4. The telescopic rods 5 are distributed on the outside of the adapter cylinder 3. The top of the telescopic rods 5 is fixedly connected to the upper horizontal section of the U-shaped frame 1.

[0031] The elastic membrane 302, which expands under pressure, pushes the pressure plate 4 downward. The pressure plate 4 moves up and down in a straight line under the extension and retraction of the telescopic rod 5. A piece of gauze is placed between the pressure plate 4 and the puncture site. The pressure plate 4 can then press down on the puncture site through the gauze to achieve the effect of compression hemostasis.

[0032] Air is introduced into the adapter tube 3 through the transparent pressurization tube 2, such as... Figure 1 , Figure 4 , Figure 5 As shown, an installation groove 101 is provided on the upper horizontal section of the U-shaped frame 1, and the transparent pressure cylinder 2 is fixedly installed on the inner wall of the installation groove 101. The surface of the transparent pressure cylinder 2 is provided with scale.

[0033] The transparent pressure cylinder 2 is provided with a movable plug 201 inside. The outer end of the movable plug 201 is in contact with the inner wall of the transparent pressure cylinder 2. A spring 202 is fixedly provided on the side of the movable plug 201 away from the adapter cylinder 3. An annular protrusion 203 is fixedly provided on the end of the spring 202 away from the movable plug 201. The annular protrusion 203 is installed on the inner wall of the transparent pressure cylinder 2.

[0034] By pulling the movable plug 201, the movable plug 201 is moved away from the adapter cylinder 3. During this process, external air is drawn into the transparent pressure cylinder 2. When the movable plug 201 moves away from the adapter cylinder 3, it will compress the spring 202. After it is released, the elastic force of the spring 202 will push the movable plug 201 closer to the adapter cylinder 3, injecting air into the adapter cylinder 3 for air supply and pressurizing the air, so that the air inside the adapter cylinder 3 is in a high-pressure state. As the air leaks out, the movable plug 201 gradually moves closer to the adapter cylinder 3 until the air in the transparent pressure cylinder 2 is completely discharged. After the air is completely discharged, the pressure will stop to stop the bleeding.

[0035] To manually control the movement of the moving piston 201, such as Figure 1 , Figure 3 , Figure 4 As shown, a connecting pipe 7 is provided between the transparent pressure cylinder 2 and the adapter cylinder 3. The two ends of the connecting pipe 7 are fixedly connected to the transparent pressure cylinder 2 and the adapter cylinder 3 respectively and communicate with both of them. A ventilation hose 8 is provided on the side of the movable plug 201 away from the adapter cylinder 3. The two ends of the ventilation hose 8 are located inside and outside the transparent pressure cylinder 2 respectively.

[0036] Both ends of the ventilation hose 8 are fixed with rigid end tubes 9. The rigid end tube 9 inside the transparent pressure cylinder 2 passes through the movable plug 201. The rigid end tube 9 outside the transparent pressure cylinder 2 is fixed with a one-way valve, so that air can only be drawn in and cannot be discharged. The air entering the transparent pressure cylinder 2 can only be introduced into the adapter cylinder 3 through the connecting pipe 7. Two finger rings 10 are fixed at the outer end of the rigid end tube 9 outside the transparent pressure cylinder 2.

[0037] The operator inserts their finger into the finger ring 10 and pulls the outer rigid end tube 9, which in turn pulls the ventilation hose 8. This allows the movable plug 201 to be pulled gradually away from the adapter cylinder 3. Simultaneously, external air enters the transparent pressure cylinder 2 along the ventilation hose 8 and the two rigid end tubes 9. This allows air to be drawn in before pressure hemostasis. The farther the movable plug 201 is pulled from the adapter cylinder 3, the more air is drawn in, and the longer it takes to completely expel the air, thus extending the pressure hemostasis time. Therefore, during the process of pulling the movable plug 201 to induce air intake, the pressure hemostasis time is extended. By observing the movement position of the movable plug 201, the inhalation volume can be adjusted, and the compression hemostasis time can be adjusted as needed. Once the set time is reached, the air in the transparent pressure cylinder 2 will be completely expelled, and the compression hemostasis will stop immediately, avoiding excessive compression hemostasis time and causing poor blood flow, thus improving the efficiency of compression hemostasis. The relationship between the exhaust speed of the micro ventilation tube 301 and the movement position of the movable plug 201 is calculated and preset, so it is possible to set the compression hemostasis time by adjusting the position of the movable plug 201.

[0038] The hemostatic device needs to be clamped and secured to the patient's arm, such as Figure 1 , Figure 2 , Figure 6 As shown, the top of the lower horizontal section of the U-shaped frame 1 is provided with a support component 6. The support component 6 is located directly below the adapter cylinder 3. The support component 6 includes a pad 601 fixedly installed at the top of the lower horizontal section of the U-shaped frame 1. The top of the pad 601 is threaded with a lifting sleeve 602. The top of the lifting sleeve 602 is fixedly provided with a soft pad 603.

[0039] When the U-shaped frame 1 is clamped on the patient's arm, the lifting sleeve 602 needs to be rotated first. Under the action of the threads, the lifting sleeve 602 moves up and down, adjusting the overall height of the support component 6 and the distance between the pressure plate 4 and the support component 6, so that the patient's arm is slightly clamped between the support component 6 and the pressure plate 4, and the soft pad 603 is in direct contact with the patient's skin, improving comfort.

[0040] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
