Description

Technical Field

[0001] This utility model relates to the field of medical devices, and more specifically, to a radial artery compressor with direct visual pressure feedback. Background Technology

[0002] Radial artery blood sampling, also known as radial artery blood gas analysis or radial artery blood collection, is a medical procedure used to draw a blood sample from the radial artery to assess the body's oxygen levels and acid-base balance.

[0003] The radial artery is a branch (or terminal branch) of the brachial artery. It runs along the radial side of the forearm to the palm, where it merges with the ulnar artery and branches out to the fingers.

[0004] After drawing blood from the radial artery, a pressure hemostat is often used to stop the bleeding.

[0005] Chinese utility model patent CN205379332U discloses an arc-shaped radial artery compressor. It includes an arc-shaped pressure block, a threaded rod, a support device, and a wristband. The arc-shaped pressure block is connected to the threaded rod, which passes through the support device. The wristband is connected to both ends of the support device. The surface of the arc-shaped pressure block has an anti-pressure ulcer drug coating, and the inner side of the wristband contains an adhesive layer. This arc-shaped radial artery compressor features a curved compression point, conforming to human ergonomics. The anti-pressure ulcer drug coating effectively prevents pressure sores, and the adhesive layer ensures the wristband stays firmly on the wrist, preventing displacement of the compressor. It also effectively reduces the area of ​​the compression point, increasing patient comfort and reducing complications caused by large-area compression.

[0006] This invention solves a problem encountered in clinical practice and has great application prospects.

[0007] In the above structure, pressure is applied directly by rotating the threaded rod. However, the operator cannot receive timely feedback on the pressure applied by the threaded rod to the patient, requiring multiple adjustments. For beginners, it is necessary to accumulate experience through repeated attempts before the pressure block can apply the appropriate amount of pressure to the patient. Utility Model Content

[0008] The purpose of this invention is to provide a radial artery compressor with direct visual pressure feedback. This invention uses a compressed air bladder to push a pressure indicator upwards. Medical personnel can judge the pressure exerted by the air bladder on the radial artery by the distance the pressure indicator rises, and then apply pressure to stop bleeding.

[0009] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0010] To address the technical problems mentioned in the background section above, some embodiments of this application provide a direct-view pressure feedback radial artery compressor, including:

[0011] Fixing plate;

[0012] A strap is attached to one end of the fixation plate to secure it to the patient's arm.

[0013] Direct-view pressure feedback radial artery compressors also include:

[0014] The pressure-applying component is movably mounted on the fixed plate;

[0015] The drive unit, mounted on the fixed plate, is used to drive the movement of the pressure-applying component;

[0016] The airbag is located on the pressure-applying component, at the lower end of the pressure-applying component, and abuts against the patient's arm;

[0017] The pressure indicator is slidably mounted on the pressure-applying component.

[0018] The pressure-applying component has an air hole that communicates with the airbag; the pressure indicator is slidably positioned inside the air hole.

[0019] Furthermore, the drive group includes:

[0020] A rotating component, rotatably mounted on a fixed plate;

[0021] A limiting element is provided on the rotating component;

[0022] Anti-rotation component, fixed to the fixed plate, used as an anti-rotation pressure component;

[0023] The rotating component has a first through hole; the limiting component is located inside the first through hole; the limiting component has a threaded hole; the pressure applying component is threaded into the threaded hole; the anti-rotation component has a second through hole; the inner wall of the second through hole has an anti-rotation surface; the anti-rotation surface abuts against the side wall of the pressure applying component.

[0024] Furthermore, the side wall of the pressure-applying component has a driving surface and an abutting surface; the driving surface is an arc surface; the abutting surface is a horizontal surface; the driving surface has a threaded groove that is threadedly connected to the threaded hole.

[0025] Furthermore, the pressure indicator includes:

[0026] The sliding part is slidably disposed inside the air hole;

[0027] An indicator is provided on the sliding part;

[0028] The indicator section is divided into three zones from top to bottom: too loose, fit, and too tight.

[0029] Furthermore, the cross-section of the indicator is larger than the cross-section of the sliding part.

[0030] Furthermore, a spring is fitted onto the indicator part; the lower end of the spring abuts against the upper end face of the sliding part.

[0031] The air hole has an abutment ring on its inner wall, located above the spring; the upper end of the spring abuts against the abutment ring; and the indicator part passes through the abutment ring and protrudes outside the air hole.

[0032] Furthermore, different colors are applied to the loose, fitted, and tight areas respectively.

[0033] Furthermore, the end of the fixing plate away from the strap has a winding hole.

[0034] Furthermore, the straps are equipped with Velcro.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. By compressing air into the airbag, the pressure indicator is pushed upward, allowing medical staff to judge the pressure of the airbag on the patient's radial artery by the upward movement of the pressure indicator (the movement of the indicator rod), enabling medical staff to quickly become familiar with the use of the compression device.

[0037] 2. By setting up three zones on the indicator from top to bottom—a loose zone, a suitable zone, and a tight zone—and coloring these three zones with three different colors, medical staff can easily observe the distance the indicator has moved upward, making the indication more accurate.

[0060] It should also be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0061] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are used only to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0062] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0063] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0064] Reference Figure 1-8 A direct-view pressure feedback radial artery compressor includes: a fixation plate 101, a strap 102, a pressure applicator 103, a drive assembly 104, an airbag 105, and a pressure indicator 106. The middle section of the fixation plate 101 is arc-shaped to cover the surface of the arm. The strap 102 is fixed to one end of the fixation plate 101, and the end of the fixation plate 101 away from the strap 102 has a winding hole 101a. Velcro 107 is sewn onto the strap 102. The pressure member 103 is movably mounted on the fixed plate 101; the drive assembly 104 is mounted on the fixed plate 101 and is used to drive the pressure member 103 to move up and down; the airbag 105 is fixed to the lower end of the pressure member 103; an air hole 103a communicating with the airbag 105 is provided on the pressure member 103, and a pressure indicator 106 is provided in the air hole 103a (the pressure indicator 106 can be a conventional simple pressure gauge, such as a simple pressure gauge on an infusion pressure bag).

[0065] The airbag 105 and pressure-applying component 103 can be made of transparent material to facilitate observation of bleeding.

[0066] The fixation plate 101 is pressed onto the radial artery on the patient's arm. Then, the bandage 102 is wrapped around the arm and inserted into the wrapping hole 101a. The bandage 102 is then folded over and secured with Velcro 107, fixing the fixation plate 101 and the bandage 102 to the arm. Then, the driving assembly 104 drives the pressure applying component 103 to move downward. The pressure applying component 103 drives the airbag 105 to move downward. The airbag 105 compresses the radial artery on the patient's arm to stop bleeding. When the pressure applying component 103 moves downward and compresses the airbag 105, the air inside the airbag 105 enters the air hole 103a, pushing the pressure indicator 106 upward. Medical staff can judge the pressure of the airbag 105 on the patient's radial artery by how much the pressure indicator 106 moves upward.

[0067] Gauze or cotton can be placed between the airbag 105 and the patient's skin.

[0068] The drive assembly 104 includes: a rotating component 104a, a limiting component 104b, and an anti-rotation component 104c; the rotating component 104a is rotatably mounted on the fixed plate 101, and a first through hole 104d is formed on the rotating component 104a; the limiting component 104b is located inside the first through hole 104d, and a threaded hole 104e is formed on the limiting component 104b, and a pressure applying component 103 is threadedly connected to the threaded hole 104e; the anti-rotation component 104c is fixed on the fixed plate 101, and a second through hole 104f is formed on the anti-rotation component 104c, and an anti-rotation surface 104g is formed on the inner wall of the second through hole 104f, the anti-rotation surface 104g being a plane.

[0069] The side wall of the pressure-applying member 103 has a driving surface 104h and an abutting surface 104i. The driving surface 104h is an arc surface, and the abutting surface 104i is a plane. The driving surface 104h has a threaded groove that is threadedly connected to the threaded hole 104e. The abutting surface 104i is in contact with the anti-rotation surface 104g.

[0070] The pressure indicator 106 includes: a sliding part 104j and an indicator part 104k; the sliding part 104j is disc-shaped and slides up and down within the air hole 103a; the indicator part 104k is rod-shaped and integrally formed on the sliding part 104j. The diameter of the indicator part 104k is smaller than the diameter of the sliding part 104j. The indicator part 104k is divided into an overly loose area 104p, an adapting area 104q, and an overly tight area 104u from top to bottom. The overly loose area 104p, the adapting area 104q, and the overly tight area 104u can be painted with three different colors for differentiation (the specific positions of the overly loose area 104p, the adapting area 104q, and the overly tight area 104u can be determined through multiple experiments).

[0071] An abutment ring 108 is fixed inside the vent 103a. The abutment ring 108 is located above the sliding part 104j. The indicator part 104k passes through the abutment ring 108. A spring 109 is sleeved on the indicator part 104k. The upper and lower ends of the spring 109 abut against the abutment ring 108 and the sliding part 104j, respectively.

[0072] When the pressure-applying component 103 is moved downward, the rotating component 104a is rotated, which drives the limiting component 104b to rotate synchronously. The anti-rotation surface 104g is in close contact with the abutment surface 104i, restricting the rotation of the pressure-applying component 103. When the limiting component 104b rotates, it drives the pressure-applying component 103 to move downward through the threaded hole 104e and the thread on the driving surface 104h, which in turn drives the airbag 105 to move downward, applying pressure to the radial artery to achieve the effect of hemostasis.

[0073] When the pressure-applying component 103 moves downward and squeezes the airbag 105, the air inside the airbag 105 enters the air hole 103a, pushing the pressure indicator 106 upward and compressing the spring 109. When the pressure indicator 106 moves upward and exposes the loose area 104p, it means that the airbag 105 is not applying enough pressure to the radial artery. When it exposes the suitable area 104q, it means that the airbag 105 is applying appropriate pressure to the radial artery. When it exposes the tight area 104u, it means that the airbag 105 is applying too much pressure to the radial artery and needs adjustment.

[0074] When the pressure-applying component 103 needs to move upward, the reverse rotating component 104a is reversed, causing the pressure-applying component 103 to move upward. The spring 109 is released and reset, causing the pressure indicator 106 to move downward. The pressure indicator 106 compresses the air in the air hole 103a back into the airbag 105.

[0075] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
