Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, in particular to an artery compressor. Background Art

[0002] Arterial blood gas analysis is a commonly used blood test method in clinical practice, and is often used for monitoring respiratory failure and acid-base imbalance, as well as for adjusting mechanical ventilation parameters, analyzing efficacy, and judging prognosis. In clinical practice, arterial blood is usually collected from the femoral artery, brachial artery, and radial artery. After collection, the puncture point needs to be pressed to prevent further bleeding.

[0003] In clinical practice, most patients are asked to stop bleeding by manual pressure. However, arterial pressure is higher than venous pressure. After puncture, the local puncture point needs to be pressed for 5-10 minutes. Patients with abnormal coagulation function need longer time. During the pressing process, patients may experience sore fingers, resulting in insufficient pressure.

[0004] The prior art also provides an artery compressor that can replace manual compression. The pressing block is fixed to the puncture point by a fixing belt to achieve compression on the puncture point, thereby replacing manual compression. However, the artery compressor commonly used in the prior art mentioned above, when fixed, only the pressing block and the fixing belt are in contact with the skin, and the pressing block is slightly suspended due to the fixing belt, and the fixing belt may be easily loosened when fixed, which may cause the pressing block to shift and fail to effectively compress the puncture point.

[0005] Secondly, the above-mentioned arterial compressor is not easy to adjust the compression force. If the pressure is not appropriate, it may cause harm to the patient. For example, too little compression force may cause bleeding in the puncture wound and fail to achieve the effect of compression and hemostasis; too much compression force may cause local pain in the compressed part of the patient, as well as cause skin bruises, blisters, damage or subcutaneous hematoma, slow blood flow, etc., which may cause discomfort to the patient and may even cause the formation of a pseudoaneurysm. Summary of the invention

[0006] The invention provides an artery compressor, and the technical problem to be solved is that the compression force can be adjusted.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] An arterial compressor comprises a compressor body and a fixing belt, wherein the fixing belt is provided with Velcro, and both ends of the compressor body are fixed to the patient's limbs through the fixing belt. The compressor body comprises a bracket, an adjusting rod and a silicone pressing block, wherein the bracket is in a "bow" shape, and a through hole matching the cross-sectional shape of the adjusting rod is provided in the middle part, and the adjusting rod can movably pass through the bracket through the through hole, and the silicone pressing block is provided at one end of the adjusting rod located on the concave side of the bracket, and the pressure of the silicone pressing block on the puncture point can be adjusted by operating the adjusting rod.

[0009] Compared with the prior art, the present invention achieves at least the following beneficial effects: an arterial compressor in the present invention increases the contact points with the patient's skin through a "bow"-shaped bracket, thereby improving the firmness when fixed on the patient's limbs, reducing the possibility of displacement of the compressor main component after fixation, and can operate the adjustment rod according to the patient's feedback to adjust the compression force, thereby reducing the adverse effects caused by inappropriate compression force.

[0020] In view of the defects of the prior art that the compression force is not appropriate during pressing, the compression may not stop bleeding, or may cause harm to the patient. After careful analysis, the inventor found that the main reason for the above problems of the existing compressor is that the compression force cannot be adjusted. Based on the above analysis, the inventor has made structural improvements to the artery compressor.

[0021] like Figure 1-6 As shown, an arterial compressor in the present application includes a compressor body 1, a fixing belt 2 and a sensing adjustment component 3.

[0022] Embodiment 1

[0023] Among them, reference Figure 1-3The two ends of the compressor body 1 are fixed to the patient's limbs through the fixing belts 2. The compressor body 1 includes a bracket 11, an adjusting rod 12 and a silicone pressing block 13. The bracket 11 is in a "bow" shape, and a through hole 111 adapted to the cross-sectional shape of the adjusting rod 12 is arranged in the middle. The adjusting rod 12 can movably pass through the bracket 11 through the through hole 111. The silicone pressing block 13 is arranged at one end of the adjusting rod 12 located on the concave side of the bracket 11. The pressure of the silicone pressing block 13 on the puncture point can be adjusted by manipulating the adjusting rod 12.

[0024] When in use, the "bow"-shaped bracket 11 can enable the silicone pressing block 13 and both ends to contact the skin, increase the contact points with the patient's skin, improve the firmness when fixed on the patient's limbs, and reduce the possibility of displacement of the main part of the compressor after fixation; and the pressure of the silicone pressing block 13 on the puncture point can be adjusted by operating the adjustment rod 12 according to the patient's feedback, thereby reducing the adverse effects caused by inappropriate pressure.

[0025] The bracket 11 also includes a fixed plate 112 and a movable plate 113. The through hole 111 is arranged on the fixed plate 112. The movable plate 113 is located on both sides of the fixed plate 112, and one end can be slidably inserted into the fixed plate 112. The fixed plate 112 is threadedly connected with fastening bolts 114 on both sides. The fastening bolts 114 can abut against the movable plate 113 to relatively fix the movable plate 113 and the fixed plate 112; thus, the length of the bracket 11 can be adjusted as needed to adapt to patients with different arm sizes and different thigh thicknesses.

[0026] In the first embodiment, the compressor body 1 further includes an adjusting nut 15 and a spring 16. The adjusting rod 12 is slidably connected to the through hole 111, and a blocking block 121 is provided at the other end of the adjusting rod 12. The adjusting nut 15 and the spring 16 are both located at one end of the adjusting rod 12 close to the silicone pressing block 13. The adjusting nut 15 is threadedly connected to the adjusting rod 12, and the spring 16 is sleeved on the adjusting rod 12, and the two ends are respectively in contact with the adjusting nut 15 and the bracket 11. By rotating the adjusting nut 15, the adjusting nut 15 can move up and down along the length direction of the adjusting rod 12, thereby changing the compression degree of the spring 16, and then adjusting the pressure of the silicone pressing block 13 according to the patient's feedback.

[0027] At least one plane 122 is provided on the side wall of the adjusting rod 12 along the length direction, and a through hole 111 adapted to the cross-sectional shape of the adjusting rod 12 is provided in the middle of the bracket 11, so that the adjusting rod 12 can be restricted from rotating, thereby avoiding friction on the skin at the puncture point.

[0028] A boss 14 is provided at one end of the adjusting rod 12, and a connecting sleeve 131 which can be sleeved on the boss 14 is provided on the silicone pressing block 13. The silicone pressing block 13 can be detachably connected to the boss 14 at one end of the adjusting rod 12 through the connecting sleeve 131. The silicone pressing block 13 is detachably connected to the boss 14, which can facilitate the disassembly and replacement of the silicone pressing block 13. After a patient uses it, the used silicone pressing block 13 can be discarded, and the remaining parts can be reused after being sterilized, thereby reducing medical costs.

[0029] Among them, the fixing belt 2 is provided with Velcro 21, through which the two ends of the fixing belt 2 can be adhered to each other, and the fixing belt 2 is provided with an elastic part 22, which can increase the firmness of the fixation and further reduce the possibility of displacement of the main part of the compressor after fixation.

[0030] Among them, reference Figure 4 The sensing and adjusting component 3 includes a pressure sensor 31, a display screen 32 and a power supply 33. The power supply 33 is arranged in the display screen 32 for supplying power to the pressure sensor 31 and the display screen 32. The pressure sensor 31 is arranged between the boss 14 and the silicone pressing block 13. The display screen 32 is arranged on the upper side of the bracket 11, and the display screen 32 and the pressure sensor 31 are electrically connected.

[0031] By means of the display screen 32 arranged on the upper side of the bracket 11 and the pressure sensor 31 electrically connected to the display screen 32, the pressure force exerted by the pressing block on the puncture point can be intuitively known, and the pressure force can be further standardized to prevent the pressing block from exerting improper pressure on the puncture wound. The device is easy to use and simple to operate, can improve the compression hemostasis effect, and can reduce the damage to the patient's body.

[0032] The sensing adjustment component 3 also includes a central control module 34 and a drive motor 35. A circuit box is arranged in the display screen 32, wherein the battery and the central control module 34 are arranged in the circuit box. The pressure sensor 31, the display screen 32, the power supply 33 and the drive motor 35 are all electrically connected to the central control module 34, and an input button 36 is also arranged on the display screen 32. One end of the drive motor 35 is engaged with the adjustment nut 15. The central control module 34 receives the pressure value transmitted by the pressure sensor 31 and compares it with the preset value input by the input button 36, thereby controlling the drive motor 35 to drive the adjustment nut 15 to rotate.

[0033] Therefore, during the compression hemostasis process, the pressure sensor 31 can detect the pressure of the pressing block on the puncture point in real time during the entire hemostasis process, and the drive motor 35 drives the adjusting nut 15, so that when the pressure of the pressing block is less than the preset value, the pressure of the pressing block can be increased, and when the pressure of the pressing block is greater than the preset value, the pressure of the pressing block can be reduced, thereby realizing automatic control of the pressure, which can not only ensure the hemostasis effect, but also prevent femoral artery blood flow blockage caused by excessive pressure. Among them, the preset value of the pressure can be input into the central control module 34 by the doctor or nurse through the input button 36 according to specific needs.

[0034] During use, the medical staff aligns the silicone pressing block 13 in the compressor body 1 with the puncture point and adjusts it so that both ends of the bracket 11 are supported on the skin. Then, the compressor body 1 is fixed to the patient's limb using the fixing belt 2. At this time, based on the patient's comfort feedback or a prepared compression force standard manual, the compression force value displayed on the display screen 32 can be used to change the degree of compression of the spring 16 by manually rotating the adjusting nut 15 or by driving the drive motor 35 to adjust the compression force of the silicone pressing block 13 so that the compression force meets the requirements of the manual and the patient's comfort needs.

[0035] Embodiment 2

[0036] refer to Figure 1 The two ends of the compressor body 1 are fixed to the patient's limbs through the fixing belts 2. The compressor body 1 includes a bracket 11, an adjusting rod 12 and a silicone pressing block 13. The bracket 11 is in a "bow" shape, and a through hole 111 adapted to the cross-sectional shape of the adjusting rod 12 is arranged in the middle. The adjusting rod 12 can movably pass through the bracket 11 through the through hole 111. The silicone pressing block 13 is arranged at one end of the adjusting rod 12 located on the concave side of the bracket 11. The pressure of the silicone pressing block 13 on the puncture point can be adjusted by manipulating the adjusting rod 12.

[0037] Different from the above-mentioned embodiment 1, in this embodiment 2, reference Figure 5 and Figure 6 The adjusting rod 12 is threadedly connected to the through hole 111, and a rotating handle 123 is provided at the other end of the adjusting rod 12. By operating the rotating handle 123 to rotate the adjusting rod 12, the length of the adjusting rod 12 inserted into the bracket 11 can be changed, thereby achieving the effect of being able to adjust the pressure force.

[0038] Among them, the driving motor 35 in the sensing and adjusting component 3 can engage with the rotating handle 123. During the compression hemostasis process, the pressure sensor 31 can detect the pressure force of the pressing block on the puncture point in real time during the entire hemostasis process, and the driving motor 35 drives the rotating handle 123. When the pressure force of the pressing block is less than the preset value, the pressure force of the pressing block can be increased, and when the pressure force of the pressing block is greater than the preset value, the pressure force of the pressing block can be reduced, thereby realizing automatic control of the pressure force.

[0039] A boss 14 is provided at one end of the adjusting rod 12, and a connecting sleeve 131 which can be sleeved on the boss 14 is provided on the silicone pressing block 13, and the silicone pressing block 13 can be detachably connected to the boss 14 at one end of the adjusting rod 12 through the connecting sleeve 131. A rotating groove 124 is provided at the connecting end of the adjusting rod 12 and the boss 14, and a T-shaped rotating block 141 is provided on the boss 14, and the boss 14 is rotatably inserted into the rotating groove 124 through the T-shaped rotating block 141 to connect with the adjusting rod 12.

[0040] In order to prevent the pressing block from rotating when the adjusting rod 12 rotates, causing the pressing block to cause friction on the skin at the puncture point, the boss 14 is rotatably inserted into the rotating groove 124 through the T-shaped rotating block 141 and connected to the adjusting rod 12, so that when the rotating handle 123 is rotated to drive the adjusting rod 12 to rotate, the adjusting rod 12 can rotate relative to the boss 14, thereby keeping the boss 14 relatively still.

[0041] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present invention should be within the protection scope of the present invention.
