AI Technical Summary
Existing hemostatic devices tend to rotate the pressure block when the adjustment mechanism is turned, making it impossible to use pressure blocks of special specifications and the strap structure cannot be effectively adhered to the torso, resulting in poor hemostatic effect.
A pouch compressor was designed, comprising a rotating sleeve, a telescopic component, a housing, and a bottom cover. The rotation of the telescopic component is restricted by an internal and external thread structure. Combined with a transparent housing and a removable bottom cover, the telescopic component can be raised and lowered directly, ensuring effective contact between the strap and the skin and hemostatic compression.
It achieves stable expansion and contraction of the telescopic component and effective adhesion of the strap, avoiding changes in the compression angle, improving the hemostasis effect and the contact area of the strap, and adapting to the hemostasis needs of different scenarios.

Abstract
Description
Technical Field
[0001] This invention belongs to the medical field, specifically relating to a bag compression device. Background Technology
[0002] Patent CN 219940706 U discloses a hemostatic device that controls the pressure applied to the hemostatic site by rotating an adjusting mechanism to move the pressure block back and forth. However, when the adjusting mechanism is rotated, the pressure block tends to rotate as well, making this device unsuitable for situations requiring a specially sized pressure block at a specific angle to apply pressure to the hemostatic site. Furthermore, this device restricts the installation method and structure of the bandage; if used for hemostasis on the torso, an adhesive bandage is required, and this device cannot ensure effective adhesion between the bandage and the skin near the hemostatic site. Summary of the Invention
[0003] The present invention provides a bag compression device that can effectively solve the problems in the background art.
[0004] The present invention provides a pouch compressor, comprising:
[0005] The lower part has a rotating sleeve with a raised internal thread;
[0006] A telescopic component with a columnar structure and an oval cross-section in the middle and lower parts, and external threads corresponding to the internal threads of the rotating sleeve are provided on the arc-shaped surfaces of the upper and middle side walls of the telescopic component.

[0031] like Figure 1 , 2 As shown, this embodiment includes a rotating sleeve 1, a telescopic component 2, a housing 3, and a bottom cover 4.
[0032] like Figure 3 As shown, the rotating sleeve 1 is sleeve-shaped, and the lower part of the inner sidewall of the rotating sleeve 1 is provided with a raised surface, and the raised surface is provided with an internal thread 1a. In another embodiment, the thread can also be set higher than the inner wall, and the thread can be used as a protrusion. The outer sidewall of the rotating sleeve 1 is also provided with vertical anti-slip texture 1b to facilitate the rotation of the rotating sleeve 1.
[0033] like Figure 4 , 5 As shown, the telescopic component 2 is a cylindrical structure with an oval cross-section in the middle and lower parts. The upper part of the telescopic component 2 has a full-circle external thread 2a, and the arc-shaped surface of the middle sidewall of the telescopic component 2 also has an external thread 2a, which corresponds to the internal thread 1a. The telescopic component 2 is screwed into the rotating sleeve 1 from bottom to top. Because the upper part of the telescopic component 2 has a full-circle external thread 2a, it is very easy to screw the telescopic component 2 into the rotating sleeve 1 at the beginning. Furthermore, because the lower part of the telescopic component 2 has no thread, when it reaches the lower part, the telescopic component 2 cannot rotate further, thus limiting the upward movement of the telescopic component 2. In other embodiments, a thread with a smaller pitch at the lower part of the telescopic component 2 can achieve the same effect.
[0034] In this embodiment, the advantage of providing an internal thread 1a only on the inner wall of the rotating sleeve 1, rather than making the entire inner wall of the rotating sleeve 1 internally threaded, is that it results in lower manufacturing costs. Furthermore, placing the internal thread 1a at the lower part of the inner wall of the rotating sleeve 1 minimizes the height requirement of the rotating sleeve 1. If the internal thread 1a were placed in the middle or upper part of the inner wall of the rotating sleeve 1, the rotating sleeve 1 would need to be made taller to maximize the retraction of the telescopic component 2 within it. This embodiment does not add any components; it cleverly utilizes the threaded structure of the telescopic component 2 to solve the problem of the telescopic component 2 rotating with the rotating sleeve 1, while simultaneously preventing the telescopic component 2 from detaching from the rotating sleeve 1, and also providing space for maximum observation of the pressure point.
[0035] The shell 3 is shaped like a barrel with the opening facing downwards. The shell 3 is fitted onto the rotating sleeve 1 from top to bottom. The inner diameter of the shell 3 is slightly larger than the outer diameter of the rotating sleeve 1, so that the rotating sleeve 1 can rotate freely around its axis.
[0036] The side wall of the housing 3 is provided with a hollow part 3a that can be used to rotate the rotating sleeve 1. There are two hollow parts 3a and they are symmetrically arranged. The index finger and thumb of one hand can rotate the rotating sleeve inside the housing 3 through the two hollow parts 3a.
[0037] Both the housing 3 and the telescopic component 2 are made of transparent material. The upper end of the housing 3 has a blocking part 3b that prevents the rotating sleeve 1 from detaching from the housing 3. In this embodiment, an oval-shaped through hole is opened at the upper end of the housing 3. The narrow side distance of the through hole is slightly smaller than the outer diameter of the rotating sleeve, which can effectively block the part 3b. This structure of the through hole can maximize the exposure of the telescopic component and achieve the widest range of observation.
[0038] The bottom cover 4 is plate-shaped and detachably fixed to the lower end of the housing 3. Specifically, the bottom cover 4 has four pins 4b perpendicular to it, and corresponding insertion holes are provided on the lower part of the housing 3. The pins 4b are inserted into the insertion holes with an interference fit, which allows the bottom cover 4 to be detachably fixed to the housing 3. Furthermore, the insertion holes can be designed as frustum-shaped holes with a smaller diameter at the top and a larger diameter at the bottom, which facilitates the insertion of the pins 4b and also provides a fastening effect. In other embodiments, the number of pins 4b can be determined according to the specific circumstances.
[0039] The bottom cover 4 has an oval hole 4a corresponding to the shape of the middle and lower cross-section of the telescopic member 2. The oval hole 4a can just accommodate the middle and lower part of the telescopic member 2 passing back and forth. Since the upper outer wall of the telescopic member 2 has a full circle of external threads 2a, this full circle of threads can prevent the telescopic member 2 from completely passing through the oval hole 4a downwards. Therefore, in this embodiment, the full circle of external threads 2a on the upper part of the telescopic member 2 also cleverly plays a limiting role. In addition, since the bottom cover 4 and the housing 3 are fixed by interference fit in this embodiment, when the bottom cover 4 and the housing 3 fit tightly, it is impossible to disassemble the housing 4. However, if the rotating sleeve 1 is rotated excessively, the full circle of threads on the upper part of the telescopic member 2 can give the bottom cover 4 a very stable squeezing force, causing the pin 4b to loosen from the insertion hole, creating a gap between the bottom cover 4 and the housing, and the bottom cover 4 can be removed more easily. Therefore, the structure of the telescopic member 2 and the bottom cover 4 in this embodiment is very ingenious.
[0040] Compared to the prior art in the background, this embodiment optimizes the structure of the telescopic member 2. It retains the full-circle external thread 2a at the top of the telescopic member 2, while making the middle and lower parts of the telescopic member 2 into an oval cross-section. Simultaneously, the thread at the bottom of the telescopic member 2 is removed. With the cooperation of the bottom cover 4 with the oval hole 4a, the telescopic member 2 can be prevented from rotating during vertical extension and retraction, and when the rotating sleeve 1 is rotated, the telescopic member 2 cannot completely disengage from the rotating sleeve 1 during axial movement. Preferably, this embodiment provides a short column 2b with an oval cross-section on the lower end face of the telescopic member 2. The cross-sectional dimension of the short column 2b is smaller than that of the telescopic member 2, and the straight surface of the side wall of the short column 2b is parallel to the straight surface of the side wall of the telescopic member 2. A bottom plate 2c with a dimension larger than the cross-section of the short column 2b is provided on the bottom surface of the short column 2b. Thus, an annular groove is formed between the short column 2b, the bottom plate 2c, and the telescopic member 2. This annular groove is used to install the soft pad 5.
[0041] This embodiment includes a soft pad 5, with a slot 5a of convex cross-section corresponding to the annular groove. The soft pad 5 is detachably mounted on the short post 2b via the slot 5a. This mounting structure facilitates the replacement of soft pads 5 of various shapes to adapt to different scenario requirements. Furthermore, since the cross-section of the short post 2b is oval, and the slot 5a corresponds to the shape of the short post 2b, the soft pad 5 cannot rotate freely, ensuring that the angle of the soft pad 5 when pressing on the hemostatic site does not change.
[0042] Furthermore, the telescopic component 2 is hollow and penetrates the base plate 2c. When the base plate 2c is inserted into the slot 5a, the gas in the slot 5a can be discharged through the hole on the base plate 2c. At the same time, the situation at the center of the pressure can be seen through the hollow telescopic component 2, which is convenient for timely observation and adjustment.
[0043] Preferably, it also includes a bandage 6. The pin 4b passes through the bandage 6 and is inserted into the socket to fix the bandage 6 to the housing 3. This installation structure allows the bandage 6 to only have a hole the size of the cross-sectional area of the telescopic member 2, maximizing the contact area between the bandage 6 and the skin at the hemostatic compression point. Especially when the bandage 6 is an adhesive structure, it can greatly improve the adhesion.
[0044] This embodiment also provides an assembly method, including the following steps:
[0045] S1: Rotate the rotating sleeve 1 from top to bottom to enclose the telescopic component 2;
[0046] S2: Fit the rotating sleeve 1 onto the housing 3 from top to bottom;
[0047] S3: Pass the pin 4b on the bottom cover 4 through the strap 6 and insert it into the hole to fix it.
[0048] It should be noted that the terms "upper," "lower," "top," and "bottom" used in this application are only for intuitively expressing the technical solution and for ease of understanding, and do not represent a limitation on the scope of protection.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
