Description

Technical Field

[0001] The utility model relates to the technical field of blood oxygen sensors, specifically a biological blood oxygen sensor. Background Technique

[0002] Biological blood oxygen refers to the oxygen content in biological blood. The normal range of blood oxygen is usually between 95% - 100%. Blood oxygen saturation is an important indicator to measure whether the human body is hypoxic. If the blood oxygen saturation is lower than 95%, it usually indicates that the body is hypoxic and it is necessary to go to the hospital in time for medical treatment. After clarifying the cause, oxygen inhalation measures should be taken for treatment.

[0003] A blood oxygen sensor is a sensor used to measure the oxygen content in biological blood. Blood oxygen sensors are usually used in medical devices such as monitors and ventilators to monitor the blood oxygen saturation of patients. The working principle of blood oxygen sensors is usually based on the optical principle, and the blood oxygen saturation is calculated by measuring the ratio of oxyhemoglobin and reduced hemoglobin in the blood.

[0004] The prior art patent document with publication number CN214342318U provides a silica gel finger clip type blood oxygen saturation sensor. This sensor is provided with a monitoring mechanism on the adjustment plate, and a pressure sensor arranged in the monitoring mechanism facilitates the monitoring of whether the sensor falls off during blood oxygen measurement. When the pressure sensor cannot detect pressure, it indicates that the sensor has fallen off, solving the problem that the existing finger clip type blood oxygen saturation sensor has no detection and falling off device.

[0005] In the above prior art, although this sensor is provided with a pressure sensor in the monitoring mechanism to facilitate the monitoring of whether the sensor falls off during blood oxygen measurement, solving the problem that the existing finger clip type blood oxygen saturation sensor has no detection and falling off device, however, when this sensor clamps the patient's finger, it uses the spring between the mounting plate and the adjustment plate to apply elastic extrusion. Sometimes the spring tension is too large, and the long-term clamping with excessive pressure will cause discomfort to the patient's finger and cannot apply different pressures according to the different sizes of the patient's fingers. Therefore, we need a biological blood oxygen sensor. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a biological blood oxygen sensor to solve the problem that when this sensor clamps the patient's finger, it uses the spring between the mounting plate and the adjustment plate to apply elastic extrusion.

A movable plate 407 is rotatably connected to the top of the connecting shaft 406, and a connecting block 408 is hinged to the top of the movable plate 407;

[0028] The mounting assembly 8 includes a clamping groove 801. A clamping block 802 is snap-fitted to the inner wall of the clamping groove 801, and a positioning groove 803 is snap-fitted to the inner wall of the clamping block 802.

A pull rod 806 is sleeved on the inner wall of the spring 805.

[0029] Through the above technical solution, the adjusting plate 3 can be rotated under the action of the rotating shaft 401 and the connecting rod 402. Starting the motor 403 can make the moving block 405 move and drive the movable plate 407 on the connecting shaft 406 to rotate at the same time. The rotation of the movable plate 407 can make the adjusting plate 3 at the top of the connecting block 408 rotate up and down, and then the adjusting plate 3 can clamp and fix the finger according to the thickness of the patient's finger, which is more practical than the traditional elastic clamping method, so as to avoid discomfort to the patient's finger caused by excessive pressure.

[0030] Specifically, a sensor body 5 is mounted on the bottom of the adjusting plate 3, and a power cord 6 is fixedly connected to one side of the mounting plate 1.

[0031] Through the above technical solution, it is convenient for the sensor body 5 on the top of the adjusting plate 3 to be attached to the patient's finger to detect the blood oxygen concentration of the patient. The power cord 6 can provide power support for the entire sensor.

[0032] Specifically, the connecting plate 2 and the connecting rod 402 form a rotating structure through the rotating shaft 401, and the top end of the connecting rod 402 is connected to the bottom of the adjusting plate 3.

[0033] Through the above technical solution, it is convenient for the connecting plate 2 to drive the connecting rod 402 to rotate through the rotating shaft 401, and the rotation of the connecting rod 402 can drive the adjusting plate 3 at the top to rotate, achieving the effect that the adjusting plate 3 can rotate through the connecting rod 402.

[0034] Specifically, the motor 403 and the moving block 405 form a moving structure through the lead screw 404, and the external thread of the lead screw 404 matches the internal thread of the moving block 405.

[0035] Through the above technical solution, it is convenient for starting the motor 403 to drive the lead screw 404 to rotate and at the same time drive the moving block 405 to move. One end of the lead screw 404 passes through the inner wall of the moving block 405 to rotate, achieving the effect that the moving block 405 moves.

[0036] Specifically, the moving block 405 and the movable plate 407 form a rotating structure through the connecting shaft 406, and the number of movable plates 407 is two. The movable plates 407 are arranged between the connecting shaft 406 and the connecting block 408.

[0037] Through the above technical solution, it is convenient for the moving block 405 to drive the movable plate 407 to rotate through the connecting shaft 406 during the moving process. While the movable plate 407 rotates, the adjusting plate 3 on the top of the connecting block 408 also rotates synchronously. Then, one side of the adjusting plate 3 will rotate up and down, enabling the sensor body 5 at the bottom of the adjusting plate 3 to clamp the patient's finger, and the patient can choose an appropriate clamping force according to their own needs.

[0038] Specifically, the mounting plate 1 and the clamping block 802 form a clamping structure through the clamping groove 801, and the shape and size of the clamping groove 801 match the shape and size of the clamping block 802.

[0039] Through the above technical solution, it is convenient for the rubber pad 7 to extend into the clamping groove 801 through the clamping block 802 to be connected with the mounting plate 1, enabling the rubber pad 7 to be replaced to avoid damage to the rubber pad 7 after long-term use.

[0040] Specifically, the clamping block 802 and the positioning rod 804 form a clamping structure through the positioning groove 803, and the shape and size of the positioning groove 803 match the shape and size of the positioning rod 804. One end of the pull rod 806 passes through the spring 805 to be connected with one side of the positioning rod 804.

[0041] Through the above technical solution, it is convenient for the positioning rod 804 to extend into the positioning groove 803 under the elastic pressure of the spring 805 to limit and fix the position of the clamping block 802, and then fix the position of the rubber pad 7 to prevent the rubber pad 7 from falling off during use. And pulling the pull rod 806 by hand can drive the positioning rod 804 to move outwards, and then the positioning rod 804 is disengaged from the positioning groove 803, releasing the limit fixation of the clamping block 802, which is convenient for disassembly.

[0042] Working principle: When using this biological blood oxygen sensor, first, when clamping and detecting the patient's finger, place the patient's finger on the rubber pad 7 first, and then start the motor 403. The motor 403 drives the lead screw 404 to rotate, and the lead screw 404 drives the moving block 405 to move. The moving block 405 drives the movable plate 407 on the connecting shaft 406 to rotate. While the movable plate 407 rotates, it causes the adjusting plate 3 at the top of the connecting block 408 to rotate. The adjusting plate 3 rotates through the rotating shaft 401 at the bottom of the connecting rod 402. Then one side of the adjusting plate 3 rotates downward, making the sensor body 5 contact the patient's finger. The patient can choose an appropriate clamping force according to their own needs. When replacing the rubber pad 7, first pull the pull rod 806 by hand to drive the positioning rod 804 to move outwards, and then the positioning rod 804 is disengaged from the positioning groove 803, releasing the limit fixation of the clamping block 802. Then pull out the rubber pad 7 upwards, insert the clamping block 802 at the bottom of the new rubber pad 7 into the card slot 801 for connection, and release the pull rod 806. The positioning rod 804 can extend into the positioning groove 803 under the elastic pressure of the spring 805 to limit and fix the position of the clamping block 802, and then fix the position of the rubber pad 7 to prevent the rubber pad 7 from falling off during use. This completes all the work. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit. The scope is defined by the appended claims and their equivalents.
