Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a radial artery hemostasis compression band with pressure indicator. Background Technology

[0002] In the medical field, after radial artery puncture, effective compression of the radial artery is necessary to prevent bleeding at the puncture site. Traditional compression hemostasis methods often suffer from the problem of inaccurate pressure control. Insufficient pressure fails to achieve good hemostasis; excessive pressure may lead to poor local blood circulation, causing adverse consequences such as pain, swelling, and even tissue necrosis. Therefore, developing a radial artery hemostatic compression band that can accurately indicate the compression pressure is of significant clinical importance.

[0003] The methods described in this section are not necessarily methods that had been previously conceived or adopted. Unless otherwise specified, no method described in this section should be assumed to be prior art simply because it is included in this section. Similarly, unless otherwise specified, the issues mentioned in this section should not be considered to be accepted in any prior art. Utility Model Content

[0004] The present invention aims to provide a radial artery hemostasis compression band with pressure indication, which effectively solves the problem of inaccurate pressure control during radial artery compression hemostasis in the prior art. Through innovative structural design, it improves the accuracy and safety of hemostasis operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A radial artery hemostatic compression band with pressure indication includes a support plate, a compression airbag, and a pressure indicator. The support plate has straps at both ends for binding to the wrist. The compression airbag is located inside the support plate to compress the radial artery. The pressure indicator includes a transparent cylinder, a piston, and an elastic element. The transparent cylinder has a piston cavity, and the piston is slidably and sealingly connected within the transparent cylinder, dividing the space within the piston cavity into a first cavity and a second cavity. The first cavity communicates with the compression airbag, and the second cavity communicates with the outside atmosphere. The elastic element is located within the piston cavity to push the piston towards the first cavity. The outer side of the transparent cylinder has pressure scale markings corresponding to the piston.

[0007] Furthermore, the piston chamber extends through the right end of the transparent cylinder, and an adjusting member is threadedly connected inside the piston chamber. The elastic member is assembled inside the piston chamber and located between the adjusting member and the piston.

[0008] Furthermore, the adjusting member has a vent hole that extends through both the inside and outside.

[0009] Furthermore, the vent holes are cross-shaped.

[0010] Furthermore, the elastic element is a helical spring.

[0011] Furthermore, it also includes an inflation connector, which is connected to the compression airbag.

[0012] Furthermore, the inflation connector includes a connecting pipe and a one-way air inlet valve disposed within the connecting pipe.

[0013] Furthermore, the connecting pipe is fixedly connected to the support plate.

[0014] Furthermore, the transparent cylinder is fixed to the support plate.

[0015] Furthermore, the straps are detachably connected to both ends of the support plate.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] Ease of use: The support plate is secured to the wrist with two-section Velcro straps at both ends, making it simple and convenient to use. Medical staff can complete the installation and removal in a short time, and can also adjust the tightness of the straps at any time according to the patient's needs, improving the patient's comfort.

[0018] Accurate hemostasis: The pressure indicator can accurately monitor the compression pressure through the pressure scale markings on the piston, elastic element and transparent cylinder. Medical staff can adjust it in time according to the actual situation, effectively improving the hemostasis effect and reducing complications caused by improper pressure.

[0019] The components are rationally designed: the adjusting part has a cross-shaped vent hole, which not only facilitates gas flow to ensure accurate and stable pressure indication, but also makes it easy to use a cross-shaped tool to flexibly adjust the pressure indication sensitivity, while avoiding misoperation; the inflation connector is equipped with a one-way air inlet valve to ensure stable inflation; the elastic part uses a helical spring to meet the pushing requirements of the piston.

[0020] Cost control and performance assurance: The adjustment part can be completely unscrewed, which facilitates the maintenance and replacement of internal components and the deflation and reset of the compression balloon. It also facilitates the storage, preservation and recycling of the hemostatic compression band, reducing medical costs and ensuring reliable and stable performance. Attached Figure Description

[0027] Support plate 1, compression airbag 2, pressure indicator 3, transparent cylinder 31, piston chamber 311, first chamber 311a, second chamber 311b, pressure scale mark 312, piston 32, elastic element 33, coil spring 331, adjusting element 34, vent hole 341, inflation connector 4, connecting pipe 41, one-way air inlet valve 42. Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] Reference Figures 1-4 As shown, the radial artery hemostasis compression band with pressure indicator of this utility model includes a support plate 1, a compression airbag 2, and a pressure indicator 3.

[0030] In this embodiment, the support plate 1 has straps (not shown in the figure) connected to both ends for binding to the wrist. The straps can be a two-section structure, with each section connected to one end of the support plate 1. The two sections are connected by Velcro, with the hook and loop sides of the Velcro fitting tightly together. This makes the operation simple and convenient, allowing medical staff to complete installation and removal quickly. Furthermore, the Velcro connection method allows for flexible adjustment of the strap tightness according to the patient's comfort and needs, ensuring the hemostatic compression band is stably fixed on the wrist. This ensures both effective hemostasis and improved patient comfort, making it highly practical.

[0031] In this embodiment, the compression airbag 2 is adhered to the inner side of the support plate 1. After the hemostatic compression band is worn on the patient's wrist, it can compress the radial artery to achieve the function of compression hemostasis. The compression airbag 2 can be made of medical-grade high-elasticity rubber material. This material has good flexibility and pressure resistance, and while providing stable compression force, it will not cause damage to the patient's skin due to excessively hard material.

[0032] In this embodiment, the pressure indicator 3 includes a transparent cylinder 31, a piston 32, and an elastic element 33. The transparent cylinder 31 has a piston chamber 311, and the piston 32 is slidably connected inside the transparent cylinder 31 to divide the space inside the piston chamber 311 into a first chamber 311a and a second chamber 311b. The first chamber 311a communicates with the compression airbag 2, and the second chamber 311b communicates with the outside atmosphere. The elastic element 33 is disposed inside the piston chamber 311 and is used to push the piston 32 toward the first chamber 311a. When the pressure inside the compression airbag 2 changes, the pressure inside the first chamber 311a changes accordingly, and the piston 32 moves under the action of the pressure difference and the elastic element 33. The outside of the transparent cylinder 31 has a pressure scale mark 312 corresponding to the piston 32. By observing the position of the piston 32 and the scale mark, the pressure inside the compression airbag 2 can be directly determined, thereby achieving accurate monitoring of the radial artery compression pressure.

[0033] Furthermore, the piston chamber 311 extends through the right end of the transparent cylinder 31, and an adjusting member 34 is threadedly connected to the piston chamber 311. The elastic member 33 is assembled inside the piston chamber 311 and located between the adjusting member 34 and the piston 32. By rotating the adjusting member 34, the force exerted by the elastic member 33 on the piston 32 can be changed, thereby adjusting the sensitivity of the pressure indication according to actual needs.

[0034] The regulating element 34 has a through-hole 341, which facilitates the flow of gas inside and outside the regulating element 34 and ensures the accuracy and stability of the pressure indication.

[0035] The vent 341 of the adjusting element 34 is cross-shaped. This unique design not only facilitates the flow of gas within and outside the adjusting element 34, ensuring the accuracy and stability of the pressure indication, but also allows medical personnel to easily use common cross-shaped tools, such as Phillips screwdrivers, to insert into the vent 341 and rotate the adjusting element 34 to flexibly adjust the pressure indication sensitivity. Furthermore, this design prevents accidental operation of the adjusting element 34. In complex clinical environments, ordinary raised knob designs are prone to accidental rotation due to external objects, leading to deviations in pressure indication sensitivity and affecting the accuracy of radial artery compression pressure monitoring. The cross-shaped vent significantly reduces the possibility of accidental adjustment of the adjusting element 34, further ensuring the reliability of the pressure indication function of the hemostatic compression band, providing stable and accurate pressure monitoring support for medical personnel, and ensuring the safety of patients during the compression hemostasis process after radial artery puncture.

[0036] Furthermore, the elastic element 33 can be a helical spring 331, which has good elasticity and stability and can meet the pushing requirements of the piston 32.

[0037] In this embodiment, the hemostatic compression band also includes an inflation connector 4, which communicates with the compression airbag 2 and is used to inflate the compression airbag 2. The inflation connector 4 includes a connecting pipe 41 and a one-way air inlet valve 42 disposed within the connecting pipe 41. The one-way air inlet valve 42 ensures that gas can only enter the compression airbag 2 in one direction, preventing gas backflow. The connecting pipe 41 is fixedly connected to the support plate 1, ensuring a stable structure. The transparent cylinder 31 is fixedly connected to the support plate 1 for easy observation of the pressure scale. The bandage is detachably connected to both ends of the support plate 1 for adjustment and replacement.

[0038] Instructions for use: Adjust the length of the bandage according to the patient's wrist size, and accurately fix the hemostatic compression bandage at the radial artery of the patient's wrist. Inflate the compression bladder 2 through the inflation connector 4, while closely observing the pressure scale mark 312 corresponding to the piston 32 on the pressure indicator 3. Stop inflation when the appropriate pressure value is reached. During the hemostasis process, the sensitivity of the pressure indicator can be adjusted by rotating the adjusting component 34 as needed. After hemostasis is achieved, untie the bandage and carefully remove the hemostatic compression bandage. Use complete.

[0039] It is worth mentioning that the adjusting component 34 is connected to the transparent cylinder 31 by a thread, which allows the adjusting component 34 to be completely unscrewed from the transparent cylinder 31. When maintenance, replacement, or deflation of the compression bag 2 is required for the internal components of the hemostatic compression band, medical personnel can use a suitable tool, such as a Phillips screwdriver, to insert into the Phillips-shaped vent hole 341 of the adjusting component 34 and slowly rotate the adjusting component 34 along the thread direction to unscrew it. With the adjusting component 34 completely unscrewed, the internal structure of the piston chamber 311 is exposed. At this time, the piston 32 and the elastic element 33 can be removed from the piston chamber 311 in sequence. After the piston 32 is removed, the obstruction between the first chamber 311a and the second chamber 311b, which were originally separated by the piston 32, disappears. Since the first chamber 311a is connected to the compression bag 2 and the second chamber 311b is connected to the outside atmosphere, the compression bag 2 is directly connected to the outside atmosphere through the piston chamber 311 on the transparent cylinder 31. In this connected state, the gas in the compression bag 2 can be naturally discharged. As the gas is expelled, the compression cuff 2 gradually contracts and returns to its original position. This design is significant because, in clinical use, after radial artery compression hemostasis is achieved, the tourniquet needs to be processed for future use. This method of retracting and resetting the compression cuff 2 not only facilitates the storage and preservation of the tourniquet but also provides the necessary conditions for its subsequent reuse, reducing medical costs and improving the utilization rate of medical resources. Simultaneously, this easy-to-disassemble and maintain structural design also allows for timely inspection and replacement of vulnerable components inside the tourniquet, ensuring its reliable and stable performance.

[0040] In summary, this utility model of a radial artery hemostatic compression band with pressure indicator includes a support plate 1, a compression bladder 2, and a pressure indicator 3. The support plate 1 is secured to the wrist at both ends with two-section Velcro straps for easy installation, removal, and adjustment of tightness. The compression bladder 2, made of medical-grade high-elasticity rubber, is bonded to the inside of the support plate 1 to achieve compression hemostasis. The pressure indicator 3 accurately monitors the compression pressure via a piston 32, an elastic element 33, and pressure scale markings 312 on a transparent cylinder 31. The pressure indicator sensitivity can be adjusted by rotating an adjusting piece 34 with a cross-shaped vent hole 341 to avoid misoperation. The hemostatic compression band also features an inflation connector 4 with a one-way air inlet valve 42 to ensure stable inflation. Its use is convenient; the adjusting piece 34 can be completely unscrewed for easy maintenance and replacement of internal components and deflation and repositioning of the compression bladder 2. This facilitates the storage, preservation, and reuse of the hemostatic compression band, reducing medical costs and promoting its widespread use.
