Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a pressurized hemostasis device after arteriovenous puncture. Background Art
[0002] In clinical nursing, medical staff often need to draw blood from patients' arteries or veins or administer infusions. However, during the puncture process, the needle or catheter penetrates the blood vessel wall, causing blood to flow out of the puncture site. Therefore, after the blood is drawn or the needle is removed after the infusion, the patient needs to stop the bleeding. Applying pressure to the puncture site can reduce bleeding and help the puncture site close faster.
[0003] For patients who are awake and able to care for themselves, a cotton swab is used to apply pressure to the puncture site for 5-15 minutes. However, patients sometimes fail to apply enough pressure or apply pressure for a sufficient period of time, which can cause bleeding at the puncture site, leading to local cyanosis and making the next puncture more difficult for medical staff. Furthermore, the arm is often not positioned comfortably when applying pressure to stop bleeding.
[0004] For unconscious patients, medical staff or other monitoring personnel are required to assist with compressions after the procedure. However, due to busy schedules, to save time, medical staff will place an alcohol swab at the puncture site and wrap it with adhesive tape to apply pressure to stop bleeding. This practice not only results in insufficient pressure, affecting the hemostatic effect, but also cannot be reused, increasing costs. Furthermore, the wrapped adhesive tape reduces patient comfort and can cause skin damage in patients with sensitive skin during the process of removing the tape after hemostasis.
[0005] Therefore, it is urgent to develop a reusable pressurized hemostasis device to effectively perform pressurized hemostasis on patients after arteriovenous puncture. Utility Model Content
[0006] The purpose of the utility model is to provide a reusable post-arteriovenous puncture pressure hemostasis device in order to overcome the defects of the prior art such as insufficient pressing and low comfort.
[0007] The purpose of the utility model can be achieved through the following technical solutions:
[0008] A reusable post-arteriovenous puncture pressurized hemostasis device comprises a cuff body and a compression airbag disposed on the cuff body. The compression airbag extends through the thickness of the cuff body and is provided with a first inflation valve. The compression airbag is configured to transform from a compressed configuration to an expanded configuration after inflation and compress the puncture point.
[0009] An inflatable cushion for placing the arm is provided on the back of the cuff body, and a second inflation valve for introducing gas into the inflatable cushion is provided on the inflatable cushion;
[0010] The cuff body is provided with an adhesive component, which specifically includes an adhesive fleece surface provided on the front of the cuff body and an adhesive hook surface provided on the back of the cuff body; the adhesive fleece surface and adhesive hook surface are respectively provided at opposite ends of the two sides of the cuff body, and are used to enclose the cuff body into a ring structure.
[0011] Furthermore, the cuff body is made of elastic stretch fabric.
[0012] Furthermore, the compression airbag is located on the front side of the cuff body and is covered with a plastic shell on the outside of the airbag portion. The plastic shell is fixed to the front side of the cuff body.
[0013] Furthermore, the volume of the compression airbag portion located on the back side of the cuff body in the expanded configuration is larger than that of the airbag portion on the front side of the cuff body.
[0014] Furthermore, the compression airbag is a transparent polyurethane airbag.
[0015] Furthermore, the inflatable pillow is an elongated structure as a whole, and forms a downwardly concave arc surface after being inflated.
[0016] Furthermore, the first inflation valve and the second inflation valve can both be connected to an inflation balloon, so that rapid inflation can be achieved through a handheld inflation balloon in the hospital.
[0017] Furthermore, after the cuff body forms a ring-shaped structure, the compression airbag and the inflatable pillow are arranged opposite to each other.
[0018] Furthermore, the area of the pasting fleece surface is larger than the area of the pasting hook surface.
[0019] Furthermore, the adhesive component is made of Velcro, and the adhesive fleece surface and the adhesive hook surface are respectively the fleece surface and the hook surface of the Velcro.
[0020] Furthermore, a timing assembly is provided on the front of the cuff body, and the timing assembly includes a time display screen and an adjustment button, both of which are connected to a processor inside the timing assembly.

[0023] (2) The utility model cleverly limits the volume of the airbag on the front of the cuff body through the plastic shell, so that the gas compressing the airbag can effectively compress the puncture point.
[0024] (3) The pressurized hemostatic device of the present invention uses a transparent compression airbag that can penetrate the thickness of the cuff body, so that medical staff can better observe the effect of compression hemostasis.
[0025] (4) The adhesive component of the present invention can be made of conventional Velcro, which is convenient for pasting and fixing, and combined with the elasticity of the cuff body, the compression position can be adjusted according to the thickness of the patient's arm.
[0026] (5) A timing component can be provided on the cuff body of the present invention to time the compression time, which can effectively remind patients and medical staff to prevent poor hemostasis effect caused by insufficient compression time. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example 1:
[0041] A reusable pressure hemostasis device after arteriovenous puncture, comprising a cuff body 1 and a compression air bag 2 arranged on the cuff body 1. Figure 1-3 As shown, the compression airbag 2 runs through the thickness direction of the cuff body 1 and is provided with a first inflation valve 21. After inflation, the compression airbag 2 can be transformed from a compressed configuration to an expanded configuration and compress the puncture point.
[0042] The back of the cuff body 1 is equipped with an inflatable cushion 3 for resting the arm. The cushion 3 is equipped with a second inflation valve 31 that allows air to flow into the cushion 3. The cuff body 1 is also equipped with an adhesive assembly 4, which specifically includes a fleece adhesive surface 41 on the front of the cuff body 1 and a hook adhesive surface 42 on the back of the cuff body 1. The fleece adhesive surface 41 and the hook adhesive surface 42 are respectively provided at opposite ends of the cuff body 1, forming a ring-shaped structure around the cuff body 1.
[0043] During use, the medical professional first inflates the inflatable pillow 3 through the second inflation valve 31, then places the patient's arm on the inflatable pillow 3, overlaps the two ends of the cuff body 1, and adjusts the position appropriately so that the compression bag 2 is directly aligned with the puncture point on the patient's arm. A sterile dressing is then applied to the puncture point. The medical professional then inflates the compression bag 2 through the first inflation valve 21, causing the compression bag 2 to compress the puncture point and stop bleeding.
[0044] Example 2:
[0045] A reusable post-arteriovenous puncture pressurized hemostasis device comprises a cuff body 1 and a compression airbag 2 disposed on the cuff body 1. The difference from Example 1 is that the cuff body 1 of this embodiment is made of elastic stretch fabric. The compression airbag 2 of this embodiment is covered with a plastic shell 22 located on the front of the cuff body 1. The plastic shell 22 is fixed to the front of the cuff body 1 and serves to limit the position of the inflated compression airbag 2, allowing the introduced gas to be delivered to the airbag portion of the compression airbag 2 located on the back of the cuff body 1.
[0046] The airbag portion on the back of the cuff body 1 is larger in volume than the airbag portion on the front of the cuff body 1 in the inflated configuration, allowing the compression airbag 2 to effectively expand toward the puncture point, thereby compressing and stopping bleeding. The compression airbag 2 in this embodiment is a transparent polyurethane airbag with a thin wall and good airtightness.
[0047] The back of the cuff body 1 is equipped with an inflatable cushion 3 for resting the arm. A second inflation valve 31 is installed on the cushion 3 to allow air to enter the cushion 3. The cushion 3 is an elongated structure that, when inflated, forms a downwardly concave curved surface to conform to the curve of the arm and enhance patient comfort. When the cuff body 1 is formed into a ring, the compression bladder 2 and the inflatable cushion 3 are positioned opposite each other, allowing the patient's arm to rest squarely on the cushion 3 and the compression bladder 2 to precisely compress the puncture point.
[0048] In this embodiment, the first inflation valve 21 of the compression airbag 2 and the second inflation valve 31 of the inflatable pillow 3 can both be connected to the inflatable balls. The compression airbag 2 and the inflatable pillow 3 can be inflated through the inflatable balls commonly used in the hospital. After inflation, the inflation valve openings are quickly sealed to prevent air leakage.
[0049] Example 3:
[0050] A reusable post-arteriovenous puncture pressure hemostasis device comprises a cuff body 1 and a compression airbag 2 mounted on the cuff body 1. An inflatable pillow 3 is provided on the back of the cuff body 1 for arm support. The cuff body 1 is provided with an adhesive assembly 4, which specifically comprises a fleece adhesive surface 41 on the front of the cuff body 1 and a hook adhesive surface 42 on the back of the cuff body 1. The fleece adhesive surface 41 and the hook adhesive surface 42 are located at opposite ends of the cuff body 1, respectively, to form the cuff body 1 into a ring-shaped structure.
[0051] In this embodiment, the adhesive component 4 is made of Velcro, and the adhesive surface 41 and the adhesive hook surface 42 are respectively the Velcro surface and the hook surface. In this embodiment, the adhesive surface 41 has an area larger than the adhesive hook surface 42, so that the adhesive position can be adjusted according to the thickness of the patient's arm.
[0052] Example 4:
[0053] A reusable post-arteriovenous puncture pressure hemostasis device comprises a cuff body 1 and a compression airbag 2 mounted on the cuff body 1. An inflatable pillow 3 is provided on the back of the cuff body 1 for arm support. The cuff body 1 is provided with an adhesive assembly 4, which specifically comprises a fleece adhesive surface 41 on the front of the cuff body 1 and a hook adhesive surface 42 on the back of the cuff body 1. The fleece adhesive surface 41 and the hook adhesive surface 42 are located at opposite ends of the cuff body 1, respectively, to form the cuff body 1 into a ring-shaped structure.
[0054] like Figure 4 As shown, the front of the cuff body 1 of this embodiment is provided with a timing assembly 5. This timing assembly 5 includes a time display 51 and an adjustment button 52, both of which are connected to a processor within the timing assembly 5. The entire timing assembly is powered by an internal battery. The timing assembly 5 of this embodiment is similar to conventional timers with electronic displays in structure, connection relationships, and usage. It can perform a timing function and measure compression time, and will not be further described here.
[0055] The above description of the embodiments is intended to facilitate understanding and use of the utility model by those skilled in the art. Those skilled in the art will readily be able to make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the utility model is not limited to the above-described embodiments.
