[0003] The existing method is to stick the medical sensor to the bottom plate with tape and then contact the patient's skin for monitoring. However, in this method, the sensor is easy to slip off and affect the monitoring effect. Utility Model Content

[0004] In order to solve the technical problem that the adhesive tape adheres to the bottom plate and then contacts the patient's skin for monitoring, but is easily slid off and affects the monitoring effect, the utility model provides a medical pressure sensor.

[0005] The utility model is implemented by the following technical scheme: a medical pressure sensor, comprising a base and a pressure sensor body, wherein the pressure sensor body is arranged inside the base, an opening corresponding to the pressure sensor body is opened on the top of the base, and a telescopic belt is fixedly installed on the upper surface of the base, one end of the telescopic belt passes through one side of the base, and a clamping mechanism is arranged inside the base for quickly fixing the pressure sensor body.

[0006] As a further improvement of the above-mentioned scheme, the clamping mechanism includes a support block fixedly installed inside the base and corresponding to the pressure sensor body, and a second slide groove arranged inside the base, the interior of the second slide groove is slidably connected with a column, the top of the column is fixedly connected with a clamping plate, and a spring is arranged between one side of the clamping plate and the inner wall of the base.

[0007] Through the above technical solution, the pressure sensor body is quickly clamped and fixed by the splint to prevent it from slipping off the patient's arm, thereby ensuring the accuracy of the monitoring results.

[0008] As a further improvement of the above scheme, the front surface of the column is fixedly connected to a connecting rod, one end of the connecting rod is hinged to a push rod, the push rod passes through the front surface of the base, and a push block is fixedly connected to the intersection of the push rods, and the front surface of the base is provided with a third sliding groove for the push rod to slide.

[0009] Through the above technical solution, the push rod is driven by the pressing block to push the column, so that the column drives the clamping plate to move, which is convenient for the maintenance and replacement of the pressure sensor body and improves the work efficiency.

[0010] As a further improvement of the above solution, the pressure sensor body is placed inside the support block, and the clamping plate is arranged corresponding to the pressure sensor body.

[0011] As a further improvement of the above scheme, the telescopic belt passes through one end of the base to open a limiting hole, and a first sliding groove is opened on one side of the base. The internal sliding connection of the first sliding groove is connected to the limiting block, and the lower surface of the limiting block is fixedly connected to a limiting column corresponding to the limiting hole.

[0012] Through the above technical solution, by arranging the limit holes and the limit columns on the telescopic belt, it is convenient for people with different arm thicknesses to use it, and it is practical.

[0013] As a further improvement of the above solution, a silicone layer is provided on the lower surface of the telescopic band.

[0014] Through the above technical solution, the setting of the silicone layer makes it fit the user's arm more closely and improves comfort.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model allows the patient's arm to be passed through the inside of the telescopic belt, and one end of the telescopic belt is pulled to adjust the tightness. After the adjustment is completed, the limit block slides downward inside the first slide groove, so that the limit column is inserted into the limit hole to complete the limit, and monitoring is performed. With the use of the splint and the spring, the pressure sensor body is always in contact with the patient's arm. This design can be used by different patients, thereby ensuring that the pressure sensor is always in contact with the patient's arm, and ensuring the accuracy of the monitoring results.

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example:

[0024] Please combine Figure 1 - Figure 3 A medical pressure sensor of this embodiment includes a base 1 and a pressure sensor body 3. The pressure sensor body 3 is arranged inside the base 1. An opening 2 corresponding to the pressure sensor body 3 is opened on the top of the base 1, and a telescopic belt 4 is fixedly installed on the upper surface of the base 1. One end of the telescopic belt 4 passes through one side of the base 1. A clamping mechanism is arranged inside the base 1 for quickly fixing the pressure sensor body 3.

[0025] Please combine Figure 2 The clamping mechanism includes a support block 9 fixedly installed inside the base 1 and corresponding to the pressure sensor body 3, and a second slide groove 10 arranged inside the base 1. The second slide groove 10 is slidably connected to the inside of the column 11, and a clamping plate 12 is fixedly connected to the top of the column 11. A spring 13 is arranged between one side of the clamping plate 12 and the inner wall of the base 1.

[0026] The pressure sensor body 3 is quickly clamped and fixed by the clamping plate 12 to prevent it from slipping off the patient's arm, thereby ensuring the accuracy of the monitoring results.

[0027] Please combine Figure 3 A connecting rod 14 is fixedly connected to the front surface of the column 11, and a push rod 15 is hinged at one end of the connecting rod 14. The push rod 15 runs through the front surface of the base 1, and a pressing block 16 is fixedly connected to the intersection of the push rod 15. The front surface of the base 1 is provided with a third sliding groove 17 for the push rod 15 to slide.

[0028] The push rod 15 is driven by the pressing block 16 to push the column 11 away, so that the column 11 drives the clamping plate 12 to move, which is convenient for the maintenance and replacement of the pressure sensor body 3 and improves the work efficiency.

[0029] Please combine Figure 2 The pressure sensor body 3 is placed inside the support block 9 , and the clamping plate 12 is arranged corresponding to the pressure sensor body 3 .

[0030] Please combine Figure 1 The telescopic belt 4 passes through one end of the base 1 and is provided with a limiting hole 5. A first slide groove 8 is provided on one side of the base 1. The interior of the first slide groove 8 is slidably connected to a limiting block 6. The lower surface of the limiting block 6 is fixedly connected to a limiting column 7 corresponding to the limiting hole 5.

[0031] The arrangement of the upper limit hole 5 and the limit column 7 on the telescopic belt 4 makes it convenient for people with different arm thicknesses to use the telescopic belt, and is practical.

[0032] Please combine Figure 1 The lower surface of the stretch band 4 is provided with a silicone layer.

[0033] The setting of the silicone layer makes it fit the user's arm better and improves comfort.

[0034] The implementation principle of a medical pressure sensor in the embodiment of the present application is as follows: when working, the patient's arm is worn inside the telescopic belt 4, and one end of the telescopic belt 4 is pulled to adjust the tightness. After the adjustment is completed, the limit block 6 slides downward inside the first slide groove 8, so that the limit column 7 is inserted into the limit hole 5 to complete the limit, and monitoring is performed. With the use of the splint 12 and the spring 13, the pressure sensor body 3 is always in contact with the patient's arm to prevent slipping and affecting the monitoring effect. When the pressure sensor body 3 needs to be replaced, the push block 16 is pressed, so that the push block 16 drives the push rod 15 to move, and then the column 11 is squeezed through the connecting rod 14, so that the column 11 pulls the splint 12 to move, which is convenient for taking and placing the pressure sensor body 3 and speeds up work efficiency.
