Description

Technical Field

[0001] This utility model relates to the field of tourniquet technology, and in particular to a radial artery pressure tourniquet. Background Art

[0002] Blood gas analysis is a primary diagnostic tool for assessing a patient's internal environment in clinical practice, and its application is particularly frequent in intensive care units. To gain valuable time in patient resuscitation, nursing staff need to master various arterial puncture techniques, and the radial artery, due to its favorable location, ease of palpation, and high success rate, has become the preferred puncture site in clinical practice.

[0003] Traditionally, radial artery hemostasis involved wrapping a bandage around the puncture site. After removing the sheath, a folded sterile gauze was applied 1-2 cm above the puncture site for a certain period before wrapping the bandage again. While this method achieved hemostasis, it often required 5-10 minutes of pressure after arterial blood collection. This prolonged pressure increased the workload for medical staff, and the instability of human hand strength made it difficult to control the appropriate pressure for extended periods, resulting in a time-consuming, laborious, and ineffective procedure. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, including: a pressure block, wherein the pressure block has a groove inside; a limiting member, wherein the limiting member is disposed above the pressure block; and a fixing strap, wherein the fixing strap has an opening adapted to the limiting member.

[0005] As a further description of the above technical solution: the limiting member includes a limiting rod and a protrusion, one end of the limiting rod is connected to the pressure block, and the other end of the limiting rod is connected to the protrusion.

[0006] As a further description of the above technical solution: the fixing strip has multiple openings at equal intervals.

[0007] As a further description of the above technical solution: multiple holes and slots are provided, and a partition is formed between adjacent holes and slots.

[0008] As a further description of the above technical solution: the pressure block includes a first block and a second block, the first block is provided with a limiting post, and the second block has a limiting groove adapted to the limiting post.

[0009] As a further description of the above technical solution: a first side plate is formed on both sides of the pressure block.

[0010] As a further description of the above technical solution: the limiting post is adapted to the opening.

[0011] As a further description of the above technical solution: the pressure block is hemispherical.

[0012] As a further description of the above technical solution: at least two limiting members are provided, and the limiting members are inclinedly arranged on the pressure block.

[0013] As a further description of the above technical solution: the fixing belt is made of rubber elastic belt, and the spacing between adjacent openings is 1.5-2.0cm.

[0014] The above technical solution has the following advantages or beneficial effects:

[0015] This invention presses the bottom of a pressure block onto a gauze ball, then attaches one end of a fixing strap to the pressure block through an opening, and wraps the other end of the fixing strap around the patient's wrist. The opening above a limiting member is then inserted into the limiting member, allowing for automatic pressure application and fixation of the gauze ball using the pressure block and the fixing strap securing it. This eliminates the need for manual pressing, significantly saving nursing manpower and improving nursing efficiency. Part of the gauze ball enters the groove, increasing friction between the pressure block and the gauze ball and preventing misalignment during pressure application. Multiple equally spaced openings on the fixing strap facilitate easy adjustment of the tightness. Attached Figure Description

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In the description of this utility model, it should be noted that the terms "vertical", "up", "down", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Example 1:

[0027] like Figure 1-4 As shown, the radial artery pressure tourniquet of this utility model includes: a pressure block 1, with a groove 5 inside the pressure block 1; a limiting member 2, which is disposed above the pressure block 1; and a fixing band 3, with an opening 4 on the fixing band 3 that is adapted to the limiting member 2.

[0028] In this embodiment, after the patient completes radial artery puncture and removes the blood gas needle tip, the medical staff immediately place a gauze ball at the puncture point and press the bottom of the pressure block 1 onto the gauze ball. Then, one end of the fixing strap 3 is fastened to the pressure block 1 through the opening 4, and the other end of the fixing strap 3 is wrapped around the patient's wrist. The opening 4 passing through the limiter 2 is then embedded into the limiter 2, so that the gauze ball is pressurized by the pressure block 1 and fixed by the fixing strap 3. This achieves automatic pressure and fixation without manual pressing, greatly saving nursing manpower and improving nursing efficiency.

[0029] Among them, some of the gauze wads will enter the groove 5, which can increase the friction between the pressure block 1 and the gauze wads and prevent the gauze wads from being misaligned during pressure application. Multiple openings 4 are provided at equal intervals on the fixing belt 3 to facilitate the adjustment of tightness.

[0030] Specifically, the pressure block 1 and the fixing belt 3 are set independently, which facilitates assembly and disassembly. When some parts are damaged, only the damaged parts need to be replaced, without the need for overall replacement, thus saving costs.

[0031] like Figure 1 and Figure 2 As shown, specifically, the limiting member 2 includes a limiting rod 201 and a protrusion 202. One end of the limiting rod 201 is connected to the pressure block 1, and the other end of the limiting rod 201 is connected to the protrusion 202. Multiple openings 4 are equally spaced on the fixing band 3. The limiting rod 201 can pass through the openings 4 on the fixing band 3 to limit the fixing band 3. The protrusion 202 can prevent the fixing band 3, which is sleeved on the limiting rod 201, from popping out.

[0032] like Figure 1 and Figure 4 As shown, specifically, multiple slots 5 are provided, and a partition 6 is formed between adjacent slots 5; when the pressure block 1 squeezes the gauze ball, some of the gauze ball will enter the inside of the slot 5. The partition 6 can block the gauze ball that will enter the slot 5, so as to prevent the gauze ball from being misaligned during squeezing.

[0033] like Figure 2 and Figure 3 As shown, specifically, the pressure block 1 has a first side plate 9 formed on both sides; the first side plate 9 facilitates the taking and putting away of the pressure block 1.

[0034] like Figure 1 and Figure 2 As shown, specifically, the pressure block 1 is hemispherical, and at least two limiting members 2 are provided. The limiting members 2 are inclinedly arranged on the pressure block 1, the fixing band 3 is made of rubber elastic band, and the distance between adjacent openings 4 is 1.5-2.0cm.

[0035] Example 2:

[0036] The pressure block 1 includes a first block 101 and a second block 102. A limiting post 103 is provided on the first block 101, and a limiting groove 104 adapted to the limiting post 103 is provided inside the second block 102. The limiting post 103 is adapted to the opening 4.

[0037] In this embodiment, by fitting the opening 4 on the fixing strap 3 onto the limiting post 103, and then covering the limiting groove 104 on the second block 102 onto the limiting post 103, the fixing strap 3 can be prevented from falling off.

[0038] Working principle: After the radial artery puncture needle tip is removed, medical staff immediately place a gauze ball at the puncture point and press the bottom of the pressure block 1 onto the gauze ball. Then, one end of the fixing strap 3 is fastened to the pressure block 1 through the opening 4, and the other end of the fixing strap 3 is wrapped around the patient's wrist. The opening 4 above the limiting member 2 is then inserted into the limiting member 2, so that the gauze ball is pressurized by the pressure block 1 and fixed by the fixing strap 3. This achieves automatic pressure and fixation without manual pressing, greatly saving nursing manpower and improving nursing efficiency.

[0039] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
