Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a dorsalis pedis artery hemostat. Background Technology

[0002] Currently, gauze is commonly used in clinical practice for hemostasis after dorsalis pedis artery puncture. However, this method is inconvenient, the hemostatic pressure is uncontrollable, and the hemostatic efficiency is low. While commercially available hemostatic devices for the dorsalis pedis artery offer an improvement over gauze, they are not specifically designed for the characteristics of this artery. These devices often consist of an adhesive bandage and a fixed pressure block, similar to a combination of a pad and gauze, but they have several drawbacks: poor patient experience and comfort; inconsistent hemostatic effect; and uncontrollable pressure.

[0003] For example, Chinese patent CN117257386 A discloses a hemostatic device for dorsalis pedis artery puncture. This dorsalis pedis artery hemostatic device uses a fixing plate to fix the dorsum of the foot, and then uses two hemostatic rods for hemostasis. This device uses the hemostatic rods to apply pressure for hemostasis, and the height is adjustable in the vertical direction, achieving a certain degree of pressure control. However, its design still has shortcomings in use. It needs to wrap around almost the entire foot to achieve fixation and provide support for the hemostatic rods. If a soft material is used, it cannot provide sufficient support for the hemostatic rods; if a hard material is used, patient comfort is reduced. Furthermore, patients' foot shapes and sizes vary, making it impossible to achieve a perfect fit. Postoperatively, whether the hemostatic device is too large or too small, it will affect patient comfort and walking. Additionally, the design of the hemostatic rods is problematic: a short rod makes it inconvenient for medical staff to use, while a long rod restricts patient movement in complex spaces when covered with warm clothing postoperatively. The pressure adjustment in this design is achieved through the height of the hemostatic rod. However, the pressure is poorly visualized during use, requiring medical personnel to estimate the height value, making adjustment difficult. Although the device includes a pressure sensor, this results in an overly complex hemostatic device structure, a high risk of failure, an inability to achieve stable and effective hemostasis, and a significant increase in operating costs.

[0004] Therefore, there is a need for a foot dorsalis artery hemostat that is easy to operate, can achieve controllable pressure, and has high hemostasis efficiency. Utility Model Content

[0005] To address the existing problems, this utility model provides a dorsalis pedis artery hemostat.

[0006] To achieve the objectives of this utility model, the technical solution adopted is as follows:

[0007] A dorsalis pedis artery hemostat includes a main board, an air bladder, Velcro straps, an extension tube, a protective tube, and a connector. The main board has an air bladder with an interface. A protective tube is fixed at the interface. One end of the extension tube is connected to the protective tube, and the other end of the extension tube is connected to the connector. Velcro straps are provided at both ends of the main board and are located on both sides of the air bladder. The main board also has a first transverse slide rail, a second transverse slide rail, a first vertical slide rail, and a second vertical slide rail. The two sides of the air bladder are connected to the first vertical slide rail and the second vertical slide rail, respectively. One end of both the first and second vertical slide rails is connected to the first transverse slide rail, and the other end of both the first and second vertical slide rails is connected to the second transverse slide rail.

[0008] Based on the above technical solution, it further includes a first airbag connecting block and a second airbag connecting block. One side of the motherboard is slidably connected to the first vertical slide rail through the first airbag connecting block, and the other side of the motherboard is slidably connected to the second vertical slide rail through the second airbag connecting block. The first vertical slide rail and the second vertical slide rail are arranged in parallel.

[0009] Based on the above technical solution, further, the first vertical slide rail and the second vertical slide rail are respectively provided at both ends with a first horizontal slide rail and a second horizontal slide rail, and the first horizontal slide rail and the second horizontal slide rail are arranged in parallel.

[0010] Based on the above technical solution, further, one end of the first vertical slide rail and one end of the second vertical slide rail are both perpendicular to the first horizontal slide rail, and the other end of the first vertical slide rail and the other end of the second vertical slide rail are both perpendicular to the second horizontal slide rail.

[0011] Based on the above technical solution, it further includes a first slide rail connecting block and a second slide rail connecting block. One end of the first vertical slide rail and one end of the second vertical slide rail are respectively connected to the first horizontal slide rail through a first slide rail connecting block. The other end of the first vertical slide rail and the other end of the second vertical slide rail are respectively connected to the second horizontal slide rail through a second slide rail connecting block.

[0012] Based on the above technical solution, furthermore, the first transverse slide rail, the second transverse slide rail, the first vertical guide rail, and the second vertical slide rail are all provided with a number of protrusions.

[0013] Furthermore, based on the above technical solution, the airbag is provided with a central ring.

[0014] Furthermore, based on the above technical solution, the connector is a pinless connector.

[0015] Compared with the prior art, the beneficial effects of this utility model are specifically reflected in:

[0016] (1) The airbag in this utility model adopts a movable design. Depending on the wearer, the position of the airbag can be moved by adjusting each horizontal and vertical slide rail. Each slide rail has a protrusion inside, and the corresponding connecting block is set in the moving space formed by multiple protrusions to limit and stabilize it. After adjusting the position of the airbag, it can be effectively fixed, achieving stepless adjustment within a range. Whether worn on the left or right foot, the airbag part can fit the puncture point on the dorsum of the foot. At the same time, it can avoid the uneven pressure caused by the differences in the dorsum of the foot of different wearers, thus achieving the effect of controllable pressure and high hemostasis efficiency.

[0017] (2) The main board of this utility model is made of transparent and flexible material. When fixed to the dorsum of the foot, it can be bent arbitrarily to fit the dorsum of the foot and achieve good fixation performance. At the same time, the bleeding at the pressure point can be directly observed. Gas is inflated until the bleeding point stops, thus achieving the required compression. The hemostat can be removed by simply peeling off the Velcro, making the installation and removal operation relatively simple. The hemostat of this utility model uses an air bladder to inflate gas for effective compression, which is easy to adjust and can reduce the workload of medical staff during hemostasis.

[0023] The present invention will be further described and illustrated below with reference to the accompanying drawings and specific embodiments. The technical features of each embodiment of the present invention can be combined accordingly, provided that there is no mutual conflict.

[0024] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below. Technical features in various embodiments of this utility model can be combined appropriately without conflict.

[0025] In the description of this utility model, it should be understood that when an element is considered to be "connected" to another element, it can be directly connected to the other element or indirectly connected, i.e., there is an intermediate element. Conversely, when an element is said to be "directly" connected to another element, there is no intermediate element.

[0026] Example

[0027] Combination Figures 1-4 As shown, this embodiment provides a dorsalis pedis artery hemostat, including a main board 4, an air bladder 5, a Velcro strap 6, an extension tube 2, a protective tube 3, and a connector. The air bladder 5 has an interface, and the protective tube 3 is fixed at the interface. One end of the extension tube 2 is connected to the protective tube 3, and the other end of the extension tube 2 is connected to the connector. It should be noted that the connection method can be a fixed connection or a movable connection, depending on the actual situation. The fixed connection method can use adhesive bonding, etc., while the movable connection method can be a threaded connection. For example, one end of the extension tube 2 has an external thread structure, and the inner wall of the protective tube 3 has an internal thread structure. The protective tube 3 and the extension tube 2 are threaded together by the interlocking thread structure between the external and internal threads. Furthermore, the other end of the extension tube 2 can also have an external thread structure, and the connector has an internal thread structure. The extension tube 2 and the connector are also movably connected by a threaded connection. The connector can be a needleless connector 1.

[0028] Specifically, the motherboard 4 is equipped with an airbag 5, which is preferably located in the middle of the motherboard 4; both ends of the motherboard 4 are provided with Velcro 6, and the airbag 5 is located between the Velcro 6 at both ends. The motherboard 4 can be a combination of rectangular and semi-circular structures, and Velcro 6 is provided at both ends of the motherboard 4. It should be noted that the number of Velcro 6 at each end can be one or more, and can be reasonably set according to the actual situation.

[0029] In this embodiment, the pressure of the air bladder 5 can be varied according to the amount of gas inside it. Medical personnel can inflate the air bladder 5 with an appropriate amount of gas based on their experience. The pressure can be intuitively felt through the amount of gas injected, thus avoiding the uncontrollable pressure situation when using bandages for hemostasis. The foot dorsum hemostat in this embodiment differs from existing common foot dorsum hemostats, which use a fixed pad and binding for compression. The foot dorsum hemostat in this embodiment uses the air bladder 5 to inflate for effective compression, which is easy to adjust and reduces the operational difficulty for medical personnel during hemostasis.

[0030] In this embodiment, the motherboard 4 is further provided with two horizontal slide rails and two vertical slide rails, namely a first horizontal slide rail 7, a second horizontal slide rail 8, a first vertical slide rail 9, and a second vertical slide rail 10. The first vertical slide rail 9 and the second vertical slide rail 10 are located on both sides of the motherboard 4 and are arranged parallel to each other. A first airbag connecting block 13 and a second airbag connecting block 14 are respectively connected to both sides of the motherboard 4. One side of the motherboard 4 is slidably connected to the first vertical slide rail 9 via the first airbag connecting block 13, and the other side of the motherboard 4 is slidably connected to the second vertical slide rail 10 via the second airbag connecting block 14. Further, referring to… Figure 1 As shown, a first horizontal slide rail 7 and a second horizontal slide rail 8 are respectively provided at both ends of the first vertical slide rail 9 and the second vertical slide rail 10, and the first horizontal slide rail 7 and the second horizontal slide rail 8 are arranged in parallel. One end of the first vertical slide rail 9 and one end of the second vertical slide rail 10 are perpendicular to the first horizontal slide rail 7, and the other end of the first vertical slide rail 9 and the other end of the second vertical slide rail 10 are perpendicular to the second horizontal slide rail 8. Specifically, one end of the first vertical slide rail 9 and one end of the second vertical slide rail 10 are respectively connected to the first horizontal slide rail 7 through a first slide rail connecting block 11, and the other end of the first vertical slide rail 9 and the other end of the second vertical slide rail 10 are respectively connected to the second horizontal slide rail 8 through a second slide rail connecting block 12.

[0031] In some embodiments, the first transverse slide rail 7, the second transverse slide rail 8, the first vertical guide rail, and the second vertical slide rail 10 are each provided with a plurality of protrusions 15. Preferably, the plurality of protrusions 15 on the first transverse slide rail 7, the second transverse slide rail 8, the first vertical guide rail, and the second vertical slide rail 10 are all located internally, and the plurality of protrusions 15 are distributed on the upper and lower sides to form two rows of protrusions 15. There is a movable space between these two rows of protrusions 15, and the first airbag connecting block 13, the second airbag connecting block 14, the first slide rail connecting block 11, and the second slide rail connecting block 12 move within their respective movable spaces. It should be noted that the first airbag connecting block 13 and the second airbag connecting block 14 can be integrally formed and connected with the airbag 5.

[0032] Specifically, the airbag 5 adopts a movable design structure. Depending on the wearer, the position of the airbag 5 can be moved by adjusting the various horizontal and vertical slide rails. The protrusions 15 inside each horizontal and vertical slide rail act as limiters, effectively fixing the airbag 5 after adjustment. This allows for stepless adjustment within a certain range, ensuring that the airbag 5 conforms to the puncture point on the dorsum of the foot, whether used on the wearer's left or right foot. Simultaneously, it avoids uneven pressure concentration and incomplete compression due to differences in the dorsum of the foot among different patients.

[0033] In this embodiment, the dorsalis pedis artery hemostat can be worn in just two simple steps, which is convenient and can effectively reduce the workload of medical staff. First, fix the main board 4 to the foot. According to the location of the required compression point and the shape of the instep, adjust the position of the air bladder 5 by adjusting the various horizontal and vertical slide rails. Align the center ring 16 on the air bladder 5 with the compression point, and use multiple Velcro straps 6 to wrap and fix the main board 4 to the foot. Then, inflate the air bladder 5 with gas to stop the bleeding. Using a screw-in syringe, evacuate the air and fit it to the instep. Connect the needleless connector 1 and inflate the air bladder 5 with gas. The main board 4 is made of transparent and soft material, which can be folded at will, and the bleeding at the compression point can be directly observed. Inflate with gas until the bleeding point stops, and the compression requirement is achieved. Remove the screw-in syringe. The hemostat can be removed afterward by simply peeling off the Velcro straps 6. Moreover, the wearer can wear it directly after surgery without affecting the patient's walking, lying down, or other activities.

[0034] The above are merely embodiments of this utility model, described in a relatively specific and detailed manner, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
