Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical auxiliary devices, in particular to an arterial pressure compressor. BACKGROUND

[0002] Arterial blood gas analysis is a commonly used blood test method in clinical practice, which is often used for monitoring respiratory failure, acid-base imbalance, and adjusting mechanical ventilation parameters, analyzing treatment efficacy and predicting prognosis. Clinically, the femoral artery, brachial artery and radial artery are often selected for arterial blood collection. After collection, the puncture site needs to be pressed to prevent continuous bleeding.

[0003] In clinical practice, patients are often asked to press the puncture site manually to stop bleeding. However, the arterial pressure is higher than the venous pressure. After puncture, the puncture site needs to be pressed for 5-10 minutes. Patients with abnormal coagulation function need more time. During the pressing process, the patient may experience finger pain, which may result in insufficient compression force.

[0004] The prior art also provides an arterial pressure compressor that can replace manual pressing. The pressing block is fixed to the puncture site by a fixing belt to press the puncture site, thereby replacing manual pressing. However, the arterial pressure compressor commonly used in the prior art only contacts the skin with the pressing block and the fixing belt during fixation. The pressing block is slightly suspended by the fixing belt, and the fixing belt may loosen during fixation, which may cause the pressing block to shift and fail to effectively compress the puncture site.

[0005] Secondly, the arterial pressure compressor in the above is not convenient for adjusting the compression force. If the pressure is not appropriate, it may cause harm to the patient. For example, if the compression force is too small, it may cause bleeding at the puncture site, which may not achieve the effect of compression and hemostasis. If the compression force is too large, it may cause local pain at the compression site, and may cause skin bruising, blistering, damage or subcutaneous hematoma, slow blood flow, and other conditions, which may cause discomfort to the patient, and may even cause the formation of a false aneurysm. SUMMARY

[0006] The present application provides an arterial pressure compressor that can adjust the compression force.

[0007] To solve the above technical problems, the present application adopts the following technical solutions:

[0008] An artery compressor comprises a compressor main body and a fixing belt, the fixing belt is provided with a magic tape, the compressor main body is fixed on a patient's limb through the fixing belt at both ends, the compressor main body comprises a bracket, an adjusting rod and a silica gel pressing block, the bracket is in the shape of an arch, and a through hole matched with the cross-sectional shape of the adjusting rod is arranged in the middle part of the bracket, the adjusting rod is movably arranged through the bracket, and the silica gel pressing block is arranged at one end of the adjusting rod on the concave side of the bracket, and the compression force of the silica gel pressing block on the puncture point can be adjusted by operating the adjusting rod.

[0009] Compared with the prior art, the artery compressor of the present application has at least the following beneficial effects: the bracket in the shape of an arch increases the contact points with the patient's skin, thereby improving the firmness when fixed on the patient's limb, reducing the possibility of displacement of the compressor main body after fixation, and being able to adjust the compression force according to the feedback of the patient by operating the adjusting rod, thereby reducing the adverse effects caused by improper compression force.

Figure 4 The sensing adjusting assembly 3 comprises a pressure sensor 31, a display screen 32 and a power supply 33. The power supply 33 is arranged in the display screen 32 and is used 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 silica gel pressing block 13. The display screen 32 is arranged on the upper side of the support 11, and the display screen 32 and the pressure sensor 31 are electrically connected.

[0031] The display screen 32 arranged on the upper side of the support 11 and the pressure sensor 31 electrically connected with the display screen 32 can directly and intuitively obtain the pressing force of the pressing block on the puncture point, further standardize the pressing force, prevent the pressing block from causing improper pressing force on the puncture wound, and improve the compression hemostasis effect and reduce the harm to the patient's body.

[0032] The sensing adjusting assembly 3 further comprises a central control module 34 and a driving motor 35. The display screen 32 is provided with a circuit box. 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 driving motor 35 are electrically connected with the central control module 34. The display screen 32 is further provided with an input button 36. One end of the driving motor 35 is engaged with the adjusting nut 15. The central control module 34 compares the pressure value returned by the pressure sensor 31 with the preset value input by the input button 36, and then controls the driving motor 35 to drive the adjusting nut 15 to rotate.

[0033] Therefore, in the compression hemostasis process, the compression force of the pressing block on the puncture point can be detected in real time throughout the hemostasis process through the pressure sensor 31, and the compression force of the pressing block can be increased when the compression force of the pressing block is less than the preset value and can be reduced when the compression force of the pressing block is greater than the preset value by driving the adjusting nut 15 driven by the driving motor 35, so as to realize automatic control of the compression force, which can not only ensure the hemostasis effect, but also prevent excessive compression force from causing femoral artery blood flow blockage. The preset value of the compression force can be input into the central control module 34 by the doctor or nurse through the input button 36 according to the specific needs.

[0034] In use, the medical staff aligns the silicone pressing block 13 in the compressor body 1 with the puncture point position, adjusts so that the both ends of the support 11 are supported on the skin, and then fixes the compressor body 1 on the patient's limb by using the fixing belt 2. At this time, the compression force value displayed in the display screen 32 can be used to adjust the compression force of the silicone pressing block 13 by manually rotating or driving the adjusting nut 15 driven by the driving motor 35 to change the compression degree of the spring 16, so as to adjust the compression force of the silicone pressing block 13 to meet the requirements of the manual and the comfort needs of the patient.

The compressor body 1 includes the support 11, the adjusting rod 12 and the silicone pressing block 13. The support 11 is in the shape of "arch" and has a through hole 111 in the middle part which is matched with the cross-sectional shape of the adjusting rod 12. The adjusting rod 12 can pass through the support 11 through the through hole 111. The silicone pressing block 13 is arranged at one end of the adjusting rod 12 which is located on the concave side of the support 11. The compression force of the silicone pressing block 13 on the puncture point can be adjusted by operating the adjusting rod 12.

[0037] Different from the above-mentioned embodiment one, in this embodiment two, reference Figure 5 and Figure 6 The adjusting rod 12 is threadedly connected with the through hole 111, and the other end of the adjusting rod 12 is provided with a rotating handle 123. The length of the adjusting rod 12 inserted into the support 11 can be changed by rotating the rotating handle 123 to drive the adjusting rod 12 to rotate, so as to realize the effect of adjusting the compression force.

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

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

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

[0041] It should be understood that all the above embodiments are exemplary but not limiting, and various modifications or variations of the specific embodiments described above made by those skilled in the art under the concept of the present application shall be within the protection scope of the present application.
