Description

Technical Field

[0001] This utility model relates to the field of compression hemostat technology, specifically an improved compression hemostat. Background Technology

[0002] The groin area is a common site for arterial puncture in clinical practice. After interventional procedures, angiography, and arterial catheterization, local pressure is usually applied to the puncture site to prevent postoperative bleeding. For example... Figure 3 The diagram illustrates a commonly used compression hemostat, which uses a nut to move a threaded rod, thereby achieving pressure hemostasis via a base plate and a pressure plate.

[0003] However, in practical applications, we have found that the above-mentioned compression hemostat also has certain shortcomings, such as: The pressure plate of the aforementioned compression hemostat is designed at a right angle and is usually made of acrylic material. During prolonged compression, it is not only uncomfortable but also prone to causing skin abrasions and pressure sores. In addition, the threaded rod of the aforementioned pressure hemostat is not equipped with a visual indicator, making it difficult to determine whether pressure has been applied or the number of rotations has been completed during operation, which affects the accuracy of hemostasis and nursing efficiency.

[0013] 2. This improved compression hemostat, by setting a transparent insert in the threaded rod and having an indicator inside it, can visually reflect its status when the pressure is adjusted by rotating the nut, thus solving the problem that the compression status is not visible in the existing structure.

[0014] 3. This improved compression hemostat has a simple structure and can be directly installed on existing compression hemostats without requiring any changes to the existing ones. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the overall structure of the present invention; Figure 2 This is a cross-sectional view of the insert portion of this utility model; Figure 3 This is a schematic diagram of a compression hemostat in the prior art.

[0016] In the diagram: 1. Main plate; 2. Nut; 3. Threaded rod; 4. Base plate; 5. Pressure plate; 6. Circular pressure pad; 7. Sink; 8. Cavity; 9. Insert post; 10. Pressure cap; 11. Soft sleeve; 12. Indicator. Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to the following: Figure 3 , Figure 3 The diagram illustrates a pressure hemostat in the prior art, comprising a main body plate 1 and a nut 2 rotatably mounted on the main body plate 1. A threaded rod 3 is screwed onto the inner wall of the nut 2, and a base plate 4 is fixedly connected to the bottom end of the threaded rod 3. A pressure plate 5 is provided at the bottom of the base plate 4. In use, the threaded rod 3 can be moved by rotating the nut 2, thereby achieving pressure hemostasis by the base plate 4 and the pressure plate 5. A flat groove structure is formed on the outer wall of the threaded rod 3 to restrict the rotation of the threaded rod 3. Since this structure is existing technology in Changshu, it will not be described in detail in this embodiment.

[0019] The main improvement of the improved compression hemostat proposed in this embodiment lies in the addition of a circular silicone pressure pad 6, such as... Figure 1 As shown, the top of the circular pressure pad 6 is provided with a groove 7 corresponding to the pressure plate 5 and the bottom plate 4; The groove 7 design allows the circular pressure pad 6 to be fitted into the bottom of the pressure plate 5 and the base plate 4. By setting the circular pressure pad 6 at the bottom of the pressure plate 5 and the base plate 4, the pressure damage to the skin caused by the sharp edges of traditional hemostats is avoided, effectively improving the comfort and safety of patients during long-term wear. At the same time, the circular pressure pad 6 is made of silicone, which can provide better cushioning and fit to the pressure point area.

[0020] In this embodiment, the four corners of the main body plate 1 are also chamfered to further avoid pressure damage during prolonged pressure.

[0021] Example 2: Please see Figure 1 and Figure 2 Based on Embodiment 1, another major improvement of this utility model is the addition of a visual indication device, specifically, as follows: Figure 1 As shown, the transparent insert 9 is movably inserted into the cavity 8 opened on the threaded rod 3, and an indicator 12 is provided inside; The indicator 12 can be a hollow glass column filled with an indicator liquid (such as red ink) or an indicator light that can light up. In this way, when the insert 9 is inserted, the position of the hollow glass column or the indicator light can be observed to intuitively reflect its status when the pressure is adjusted by rotating the nut 2, thus solving the problem that the pressure state is not visible in the existing structure. To facilitate the insertion of the insert post 9, such as Figure 1 As shown, a pressure cap 10 is fixedly installed on the top of the insertion post 9.

[0022] In this embodiment, the insert 9 is made of acrylic material, which allows color or light to pass through.

[0023] When indicator light is selected as indicator 12, those skilled in the art can set electronic, control board and other structures in the plug 9 as needed. The specific circuit is a mature existing technology, so it will not be described in detail in this embodiment.

[0024] like Figure 2 As shown, the diameter of the insertion post 9 gradually decreases from top to bottom, and the outer wall is covered with a soft sleeve 11 made of transparent material; The diameter of the insertion post 9 gradually decreases from top to bottom to accommodate cavities 8 of different sizes, thus improving applicability. By wrapping it with a soft sleeve 11, it is easy to fix the insertion post 9 in the cavity 8, which can be achieved by utilizing the elastic deformation of the soft sleeve 11. In this embodiment, the soft sleeve 11 is preferably made of transparent silicone.

[0025] The core competitiveness of this utility model lies in its simple structure, which can be directly installed on existing compression hemostats without requiring any changes to the existing compression hemostats themselves.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
