Description

Technical Field

[0001] This application relates to the field of hemostat technology, and more specifically, to an arterial compression hemostat that integrates visualization and pressure monitoring. Background Technology

[0002] Existing visual compression hemostatic devices typically employ an adhesive skin with a transparent silicone compression block in the center for easy visual observation of the hemostasis process. The outer periphery (or ends) of the adhesive skin is an adhesive layer. The device is directly attached to the patient's arm via this adhesive layer (similar to applying a plaster), allowing the central silicone compression block to apply pressure to the blood vessel for hemostasis.

[0003] The aforementioned visual compression hemostat has several drawbacks during use. Because the adhesive skin is fixed in place, the tightness of the compression silicone block cannot be adjusted after it is applied to the blood vessel. Furthermore, it is difficult to remove and feels uncomfortable on the patient. Additionally, the central compression silicone block is a single piece, making its firmness difficult to adjust and inconvenient to use.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] The purpose of this application is to provide an arterial compression hemostat that integrates visual and pressure monitoring, solving the problems of inconvenience caused by the inability to adjust the tightness, disassembly, and adjustment of the softness and hardness of existing visual compression hemostats during use.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] This application provides an arterial compression hemostat integrating visualization and pressure monitoring, comprising:

[0008] Straps with mounting ports;

[0009] The hemostatic airbag is located inside the installation port and connected to the strap. The hemostatic airbag is connected to an inflation / deflation tube, which is connected to an external inflation / deflation device to inflate or deflate the hemostatic airbag.

[0010] The hemostatic airbag is a transparent airbag, and the strap is equipped with Velcro. The strap is used to wrap around the patient's arm and is secured with Velcro.

[0011] Optionally, the bandage extends along a first direction, and the hemostatic airbag is disposed between the two ends of the bandage in the first direction.

[0012] Optionally, a pull ring is provided at one end of the first direction of the strap, and a first side of Velcro is provided at the other end of the first direction of the strap. A second side of Velcro is provided on the strap and between the first side and the hemostatic airbag. The first side of the strap passes through the pull ring and turns to adhere to the second side.

[0013] Optionally, the hemostatic airbag includes: a sealing plate, the sealing plate being connected to the edge of the installation port of the strap;

[0014] Airbag component, the airbag component is set on the sealing enclosure.

[0015] Optionally, the airbag component has a long side and a wide side in the horizontal direction, and the ratio of the length of the wide side to the length of the long side of the airbag component is 0.7-1.3.

[0016] Optionally, an air supply switch is provided inside the inflation / deflation tube, which connects the inflation / deflation tube to the hemostatic cuff when the inflation / inhalation device is connected to the inflation / deflation tube.

[0017] Alternatively, the gas supply switch can block the gas supply pipe when the gas supply device is disconnected from the gas supply pipe.

[0018] Optionally, the gas supply switch includes: a blocking member, which is movably disposed inside the gas filling and discharging pipe, and the blocking member is provided with a gas supply channel. The gas supply channel moves to different positions in the gas filling and discharging pipe by moving the blocking member, so as to open or close the gas supply switch.

[0019] Elastic components, elastic component connecting and sealing components;

[0020] The sealing element moves by being pushed by the air-inhaling device or returns to its original position by being pushed by the elastic element.

[0021] Optionally, the inflation / deflation tube includes: a tube opening section, a first tube body section, and a second tube body section connected in sequence, wherein the inner diameter of the tube opening section is smaller than the inner diameter of the first tube body section, and the inner diameter of the first tube body section is smaller than the inner diameter of the second tube body section.

[0022] The plugging component is installed inside the first pipe section and is attached to the inner wall of the first pipe section. The first end of the gas transmission channel is opened on the surface of the plugging component facing the pipe opening section, and the last end is opened on the outer wall of the plugging component.

[0023] The sealing element is moved by the air intake device so that the tail end of the air delivery channel is pushed from the first pipe section into the second pipe section.

[0024] Optionally, the sealing element includes: a sealing post, which is movably disposed within the first tube section;

[0027] Optionally, the inflation / inhalation device is a syringe, which is connected to an inflation / deflation tube to inflate or inhale the hemostatic cuff.

[0028] The beneficial effects of the arterial compression hemostat integrating visualization and pressure monitoring provided in this application are at least as follows: By using a strap with Velcro, which is wrapped around the patient's arm and secured with Velcro, the tightness of the hemostat can be adjusted during application. After use, the strap can be removed by tearing off the Velcro, making disassembly of the hemostat easier and avoiding discomfort caused by it sticking to the patient. Furthermore, a transparent hemostatic cuff is used, allowing visualization during use and facilitating observation of the hemostasis status by medical personnel. The hemostatic cuff is connected to an external inflation / deflation device via an inflation / deflation tube for inflation or deflation. This adjustable inflation and deflation mechanism allows for control of the hemostatic cuff's inflation level, thus regulating its firmness. Higher inflation indicates greater cuff pressure; if medical personnel deem the pressure too high, they can deflate the cuff to reduce it. Conversely, lower inflation indicates less pressure; if medical personnel deem the pressure too low, they can inflate the cuff to increase it. Therefore, medical personnel can monitor and control the hemostatic pressure during use, making this arterial compression hemostat more convenient to use. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality of" means two or more, unless otherwise explicitly defined.

[0038] Existing visual compression hemostats suffer from several drawbacks during use, including the inability to adjust tightness, difficulty in disassembly, and limited flexibility in terms of pressure. Furthermore, the central silicone block has a semi-circular convex cross-section and an overall elliptical shape, resulting in a small compression surface area. This necessitates precise alignment of the silicone block with the wound, making it difficult for medical personnel to use. To address these issues, this solution proposes the following implementation method:

[0039] like Figure 1 , Figure 4As shown, this embodiment proposes an arterial compression hemostat integrating visualization and pressure monitoring, comprising: a bandage 100 and a hemostatic airbag 200. The bandage 100 has an installation port that penetrates both the front and back surfaces of the bandage 100. The hemostatic airbag 200 is located within the installation port and connected to the bandage 100. The hemostatic airbag 200 is a transparent airbag, allowing medical personnel to see the hemostatic site through it, thus achieving the function of visual observation of hemostasis. The hemostatic cuff 200 is connected to an inflation / deflation tube 230, which is connected to an external inflation / deflation device 10 to inflate or deflate the hemostatic cuff 200. Medical personnel can judge whether the pressure of the hemostatic cuff 200 is appropriate based on observation and experience. The external inflation / deflation device 10 can then inflate and deflate the hemostatic cuff 200 to apply appropriate pressure to the wound for hemostasis, thus achieving the pressure monitoring function of the hemostatic cuff 200. Furthermore, the bandage 100 is equipped with Velcro 110, which is used to wrap around the patient's arm and secure it using the Velcro 110. The tightness of the bandage 100 can be adjusted by attaching the Velcro 110 at different positions.

[0040] like Figure 1 , Figure 2 As shown, this embodiment of an arterial compression hemostat integrates visualization and pressure monitoring. It uses a strap 100 with Velcro 110 to wrap around the patient's arm and secure it with the Velcro 110, allowing for adjustment of tightness during application. After use, the strap 100 is removed by tearing off the Velcro 110, making disassembly easier and avoiding discomfort caused by adhesion to the patient. A transparent hemostatic airbag 200 is used, allowing visualization during use and facilitating observation of hemostasis by medical personnel. The hemostatic airbag 200 is connected to an external inflation / deflation device 10 via an inflation / deflation tube 230 for inflation and deflation. This adjustable inflation and deflation mechanism allows for the control of the inflation volume of the hemostatic cuff 200, thereby regulating its pressure. Higher inflation indicates greater pressure; if medical personnel deem the pressure too high, they can deflate the cuff to reduce it. Conversely, lower inflation indicates less pressure; if medical personnel deem the pressure too low, they can inflate the cuff to increase it. Therefore, medical personnel can monitor and control the pressure during use, making the arterial compression hemostat more convenient to use.

[0041] like Figure 1As shown, further, the bandage 100 in this embodiment can be elongated, specifically, the bandage 100 extends along a first direction, which is the length direction, and the perpendicular direction of the first direction is the width direction. Therefore, the length of the bandage 100 is much greater than its width, for example, the length of the bandage 100 is more than 10 times its width. This allows the bandage 100 to be long enough to wrap or bind around the patient's arm. The hemostatic airbag 200 is positioned between the two ends of the bandage 100 in the first direction; for example, the hemostatic airbag 200 can be positioned in the middle of the bandage 100.

[0042] like Figure 1 As shown, further, in this embodiment, one end of the strap 100 in the first direction is provided with a pull ring 120, and the other end of the strap 100 in the first direction is provided with a first surface 111 of a Velcro 110. A second surface 112 of the Velcro 110 is provided on the strap 100 and located between the first surface 111 and the hemostatic airbag 200. The first surface 111 can be a rough surface, and the second surface 112 can be a hook surface. The first surface 111 of the strap 100 passes through the pull ring 120 and turns to be bonded to the second surface 112. In the specific structure, by providing the pull ring 120, the strap 100 can be flipped after passing through the pull ring 120 and then bonded by the Velcro 110, which facilitates the binding and fixing of the strap 100. In addition, the second surface 112 also extends a certain length along the first direction, so that the first surface 111 and the second surface 112 are bonded at different positions, thereby allowing the binding position of the strap 100 to be adjusted.

[0043] like Figure 1 , Figure 2 As shown, the hemostatic airbag 200 of this embodiment further includes a sealing plate 210 and an airbag component 220. The sealing plate 210 is made of plastic or metal and mainly serves a fixing function. In the specific process, a through hole is formed in the middle of the sealing plate 210, the outer edge of the sealing plate 210 is pressed and fixed with the edge of the mounting opening of the strap 100, the inner edge of the sealing plate 210 is pressed and fixed with the airbag component 220, and a side hole is opened on one circumferential side of the sealing plate 210, through which the inflation / deflation tube 230 passes and connects with the airbag component 220. The sealing plate 210 allows for a more stable fixation between the airbag component 220 and the strap 100, and confines the airbag component 220 to the center of the sealing plate 210. When the airbag component 220 inflates, it only expands and contracts in the center of the sealing plate 210, which is also the hemostatic area. This ensures that the force of the hemostatic airbag 200 is concentrated in the hemostatic area, resulting in better hemostatic performance. The sealing plate 210 can be circular or square, and can be specifically designed according to requirements.

[0044] like Figure 1As shown, two locking plates 211 are provided on one side of the sealing panel 210 (the side facing away from the patient when in use), and the locking plates 211 form a locking position between them. The clamp of the inflation / deflation tube 230 is limited in the locking position by the locking plates 211 on both sides.

[0045] like Figure 1 As shown, further, the airbag component 220 of this embodiment has a long side and a wide side in the horizontal direction, and the ratio of the length of the wide side to the length of the long side of the airbag component 220 is 0.7-1.3. In a specific structure, the sealing plate 210 can be set as a square structure, with rounded corners at the four corners of the square. The through hole in the middle of the sealing plate 210 is also set as a square structure, so that the airbag component 220 is also square. By making the ratio of the length of the wide side to the length of the long side of the airbag component 220 close to 1:1, the entire airbag component 220 has a flat structure. The airbag component 220 is relatively flat after inflation, thereby making the surface area of ​​the compression surface for hemostasis larger, which facilitates hemostasis operations by medical personnel.

[0046] like Figure 1 , Figure 3 , Figure 4 As shown, in this embodiment, an air supply switch 300 is provided inside the inflation / deflation tube 230. When the inflation / inhalation device 10 is connected to the inflation / deflation tube 230, the air supply switch 300 connects the inflation / deflation tube 230 to the hemostatic balloon 200. Alternatively, when the inflation / inhalation device 10 is disconnected from the inflation / deflation tube 230, the air supply switch 300 blocks the inflation / deflation tube 230. The inflation volume of the hemostatic cuff 200 can be adjusted by inflating and deflating it, thereby regulating its rigidity. When inflation or deflation is required, the external inflation / inflation device 10 is inserted into the inflation / deflation tube 230. During insertion, the gas supply switch 300 is activated, opening the channel and connecting the hemostatic cuff 200 to the external inflation / inflation device 10. This allows medical personnel to perform aspiration or deflation operations, enabling monitoring and control of the hemostatic pressure, making the arterial compression hemostat more convenient to use. Once the inflation volume of the hemostatic cuff 200 is adjusted to the predetermined level, medical personnel can directly remove the inflation / inflation device 10, causing the gas supply switch 300 to return to its original position and re-seal the inflation / deflation tube 230, preventing gas leakage from the hemostatic cuff 200.

[0047] like Figure 3 , Figure 4As shown, the gas supply switch 300 in this embodiment further includes a sealing member 310 and an elastic member 330. The sealing member 310 is movably disposed within the inflation / deflation pipe 230, and a gas supply channel 320 is provided on the sealing member 310. The gas supply channel 320 moves to different positions in the inflation / deflation pipe 230 by moving the sealing member 310, thereby opening or closing it. The elastic member 330 is connected to the sealing member 310, and the sealing member 310 moves by being pushed by the inflation / inhalation device 10 or returns to its original position by being pushed by the elastic member 330. In the specific process, the external inflation / inhalation device 10 is inserted into the inflation / deflation tube 230. During insertion, the inflation / inhalation device 10 pushes the sealing member 310, causing it to move inward and compress the elastic member 330. Simultaneously, the gas delivery channel 320 moves with it, moving from a blocked position to an open position. This connects the hemostatic cuff 200 to the external inflation / inhalation device 10, allowing medical personnel to perform aspiration or deflation. Once the hemostatic cuff 200 is inflated to the predetermined level, the medical personnel can directly remove the inflation / inhalation device 10. The sealing member 310 returns to its original position due to the push of the elastic member 330, causing the gas delivery channel 320 to move back to its blocked position, thus re-sealing the inflation / deflation tube 230. This simple structure achieves both opening and sealing functions, making it highly practical.

[0048] like Figure 3 , Figure 4 As shown, further, the inflation / deflation pipe 230 of this embodiment specifically includes: a pipe opening section 231, a first pipe body section 232, and a second pipe body section 233 connected in sequence. The inner diameter of the pipe opening section 231 is smaller than the inner diameter of the first pipe body section 232, and the inner diameter of the first pipe body section 232 is smaller than the inner diameter of the second pipe body section 233. The sealing member 310 is disposed inside the first pipe body section 232 and is attached to the inner wall of the first pipe body section 232. The head end of the gas delivery channel 320 is opened on the surface of the sealing member 310 facing the pipe opening section 231, and the tail end is opened on the outer wall of the sealing member 310. The sealing member 310 is moved by the inflation / deflation device 10, so that the tail end of the gas delivery channel 320 is pushed from the first pipe body section 232 into the second pipe body section 233. After the sealing member 310 is pushed from the first tube section 232 into the second tube section 233, one end of the air supply channel 320 connects with the inflation / inhalation device 10, and the other end connects with the inner cavity of the second tube section 233, thus connecting with the airbag component 220 through the second tube section 233. Inflation and deflation can then be performed through the inflation / inhalation device 10. When the inflation / inhalation device 10 is pulled out, due to the elastic force, the sealing member 310 is pushed back into the first tube section 232, and the other end of the air supply channel 320 is pushed into the first tube section 232, sealing the air supply channel 320 through the inner wall of the first tube section 232.

[0049] like Figure 3 , Figure 4 As shown, the sealing component 310 in this embodiment further includes a sealing post 311 and a pushing platform 312. The sealing post 311 is movably disposed within the first pipe section 232, and the pushing platform 312 is disposed at one end of the sealing post 311 facing the pipe opening section 231. The head end of the gas delivery channel 320 is opened on the surface of the pushing platform 312 facing the pipe opening section 231. By providing the pushing platform 312, when the air intake device 10 is inserted from the pipe opening section 231, it can directly contact the pushing platform 312 and push the pushing platform 312 inward, thereby making the pushing process of the sealing component 310 more convenient.

[0050] like Figure 1 , Figure 4 As shown, in this embodiment, the inflation / inflation device 10 is a syringe. The syringe is connected to the inflation / deflation tube 230 to inflate or inhale the hemostatic cuff 200. Syringes are frequently used tools in medical work, and the inflation / deflation tube 230 can use a standard interface compatible with the syringe. This eliminates the need for a separately designed matching inflation / inflation device 10, making this arterial compression hemostat highly versatile.

[0051] In summary, this application provides an arterial compression hemostat integrating visual and pressure monitoring. By using a strap with Velcro, the tightness of the hemostat can be adjusted during application. A hemostatic bladder is incorporated, with an inflation / deflation tube next to it that connects to a syringe, forming a connector. This allows the syringe to inflate or depress the bladder, adjusting its firmness. The relatively flat shape of the bladder provides a larger compression surface, facilitating hemostasis.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
