For example, the outpatient general practitioner blood pressure monitor with application number CN200620119480.4 has several control buttons and a display on the front of the main unit. Inside the unit are a circuit board, printer, air pump, and blood pressure monitoring station. The circuit board contains a microprocessor and connected ECG, blood oxygen, and blood pressure monitoring modules. The air pump, controlled by the blood pressure monitoring module, is connected to the blood pressure monitoring station's airbag via a hose. The blood pressure monitoring module is connected to the air pump and the airbag via a pressure sensor. The ECG monitoring module is connected to an external ECG lead clip via an ECG connector, and the blood oxygen monitoring module is connected to an external blood oxygen probe via a blood oxygen monitoring connector. During blood pressure measurement, the hand is inserted into the inner ring of the circular airbag for subsequent measurement. However, the circular airbag is difficult to disassemble, and after prolonged exposure, it inevitably accumulates dirt, requiring frequent disinfection, which is inconvenient and needs improvement.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] Example 1:

[0028] This application discloses a blood oxygen and blood pressure monitoring device with a detachable wristband. (Refer to...) Figure 1 , Figure 2 and Figure 3 The blood oxygen and blood pressure monitoring device includes a housing 1, a wristband 2, and an air pump (not shown in the figure). The air pump is located inside the housing 1. A cavity 11 is formed on the upward-facing side of the housing 1. An inflation tube 3, which is a silicone flexible tube, is mounted on the wristband 2. The inflation tube 3 is fixed to the side of the wristband 2 facing the skin of the person being tested and communicates with an air bladder inside the wristband 2. A flexible tube 4 is connected to the inflation tube 3, and an inflation connector 41 is connected to the end of the flexible tube 4 away from the inflation tube 3. An air vent 5 is provided on the housing 1. 5 is located on the bottom wall of cavity 11. Air vent 5 is connected to the air outlet pipe of the air pump. A connecting pipe 8 is installed at air vent 5, and an inflation connector 41 is inserted outside the connecting pipe 8. Two rubber sealing rings 9 are installed between the inner wall of the inflation connector 41 and the outer wall of the connecting pipe 8. During testing, the patient wraps the wristband 2 around their wrist and secures it tightly. Air is released by the air pump, and the gas enters the airbag through air vent 5, inflation connector 41, hose 4, and inflation pipe 3, thus pressurizing the wristband 2 for subsequent testing. When not in use, the inflation connector 41 can be pulled out from air vent 5, and the hose 4 and wristband 2 can be neatly placed inside cavity 11 for storage. The rubber sealing rings 9 deform under the pressure of the inflation connector 41 and connecting pipe 8, thereby sealing the gap between the inner wall of the inflation connector 41 and the outer wall of the connecting pipe 8, ensuring a tight seal.

[0029] Reference Figure 1 and Figure 2A dust cover 6 is movably disposed at the opening of the cavity 11. A protruding edge 111 for placing the dust cover 6 is provided on the inner side wall of the cavity 11. A groove 12 for inserting the dust cover 6 is provided inside the outer shell 1, so that the dust cover 6 can enter the groove 12 through the protruding edge 111. An operating member 7 is provided on the dust cover 6 for operating the dust cover 6 to expose or close the cavity 11. The operating member 7 is a protrusion provided on the dust cover 6. The dust cover 6 is operated by moving the protrusion.

[0030] The implementation principle of the blood oxygen and blood pressure detection device with a detachable wristband 2 in this embodiment is as follows: During testing, the patient wraps the wristband 2 around their wrist and secures it tightly. Gas is released through an air pump, and the gas vent 5, inflation connector 41, hose 4, and inflation tube 3 enter the air bladder, thereby pressurizing the wristband 2 for subsequent testing. When not in use, the inflation connector 41 can be pulled out from the vent 5, and the hose 4 and wristband 2 can be neatly placed inside the cavity 11 for storage.

[0031] Example 2:

[0032] The difference between this embodiment and Embodiment 1 is that: (Refer to...) Figure 4 The operating element 7 is a through hole opened on the dust cover 6. The dust cover 6 can be operated by inserting a finger into the through hole.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
