[0039] In order to make the purpose, scheme and advantages of the technical solutions of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely below in combination with the drawings of the specific embodiments of the present application.
[0040] Embodiment: Please refer to Figures 1 to 8 :
[0041] As Figure 1 shown, the present application proposes a simple cerebrospinal fluid pressure measuring method in high-altitude areas, which is as follows:
[0042] S1, the pressure measuring tube is only communicated with the atmosphere, the cerebrospinal fluid is led out, and the cerebrospinal fluid pressure P0 at this time is obtained;When in a high-altitude area, since the air pressure is lower than the standard atmospheric pressure, the cerebrospinal fluid pressure measured by the pressure measuring tube communicated with the atmosphere will be higher than the cerebrospinal fluid pressure measured under the standard atmospheric pressure, this step is to safely lead out the cerebrospinal fluid of the patient in a normal environment;
[0043] S2, the air pressure in the air pressure compensation assembly is increased to a standard atmospheric pressure;In step S1, the pressure measuring tube is only communicated with the atmosphere, at this time, the pipeline in the air pressure compensation assembly is in a sealed state, after the air pressure in the air pressure compensation assembly is increased to a standard atmospheric pressure by external intervention in this state, the air pressure in the air pressure compensation assembly can be stably maintained;
[0044] S3, the connection between the pressure measuring tube and the atmosphere is disconnected, the pressure measuring tube is only communicated with the air pressure compensation assembly, and the cerebrospinal fluid pressure P1 at this time is obtained;After the pressure measuring tube is communicated with the air pressure compensation assembly, the pressure measuring tube-air pressure compensation assembly forms a sealed loop, at this time, the cerebrospinal fluid is in a standard atmospheric pressure environment, and the cerebrospinal fluid pressure value under a standard atmospheric pressure can be measured, and the difference ΔP between the cerebrospinal fluid pressure P0 measured in step S1 under a low air pressure environment and the standard cerebrospinal fluid pressure P1 measured in this step can also be applied to other scenes.
[0045] Based on the above method, as shown in Figure 2 The application provides a simple cerebrospinal fluid pressure measuring device in a high-altitude area, which comprises the pressure measuring tube 1 and the air pressure compensation assembly, the pressure measuring tube 1 and the air pressure compensation assembly are connected through a three-way pipeline, and the three-way pipeline controls the communication between the pressure measuring tube 1 and the atmosphere or the air pressure compensation assembly;In an embodiment, the three-way pipeline is made of flexible material, the connection between the pressure measuring tube 1 and the atmosphere or the air pressure compensation assembly can be controlled by extrusion, the three-way pipeline not only plays a communication role, but also needs to seal the air pressure compensation assembly when adjusting the air pressure in the air pressure compensation assembly.
[0046] As shown in Figure 3 And Figure 4 The three-way pipeline is a three-way valve 2, which comprises a valve body 201 and a valve ball 202;The valve ball 202 is installed on the nodes of the three pipeline directions in the valve body 201;An L-shaped connecting channel 203 is formed in the valve ball 202;When the valve ball 202 rotates, the connecting channel 203 rotates with it, and any one set of perpendicular pipeline directions is connected;In this embodiment, the three-way pipeline uses the three-way valve 2, which can quickly adjust the communication direction of the pressure measuring tube 1, and directly seal the air pressure compensation assembly when the pressure measuring tube 1 is communicated with the atmosphere, which is more efficient and convenient.
[0047] As shown in Figure 5As shown, a control knob 204 is fixedly connected to the outside of the valve ball 202. The control knob 204 rotates relative to the valve body 201. The control knob 204 improves the convenience of adjusting the three-way valve 2.
[0048] Among them, such as Figure 5 As shown, the control knob 204 is L-shaped, and the bending shape of the control knob 204 corresponds to the shape of the connecting channel 203. Since the three-way valve 2 needs to connect the pressure measuring tube 1 to the atmosphere and the pressure compensation component respectively, and close the other when the pressure measuring tube 1 is connected to one of them, its operation is relatively cumbersome. After designing the shape of the control knob 204 in this embodiment, the connection direction of the connecting channel 203 can be clearly shown by the control knob 204, which is convenient for the operator to observe and prevents incorrect operation.
[0049] Among them, such as Figure 2 and 4 As shown, the air pressure compensation component includes a connecting pipe 3 and an air injection handle 7; one end of the connecting pipe 3 is connected to a tee pipe, and the other end is connected to the air injection handle 7; in this embodiment, the air injection handle 7 can use any external air pressure source, and the air injection handle 7 can make the inside of the connecting pipe 3 reach a standard atmosphere or any air pressure environment with an accurate value.
[0050] Among them, such as Figure 4 As shown, the connecting pipe 3 includes a main pipe 301 and a branch pipe 302; the air injection handle 7 is connected to the end of the branch pipe 302, and the end of the main pipe 301 is connected to an air reservoir 4; by designing branch pipes, the air pressure compensation component can add more safety or convenience accessories, such as the air reservoir 4 in this embodiment. Using the air reservoir 4 can significantly increase the pressure threshold that the connecting pipe 3 can withstand, avoiding the connection pipe 3 being unable to withstand high pressure when the air pressure compensation component requires higher pressure.
[0051] Among them, such as Figure 6 As shown, a pressure gauge 5 is connected to the connecting pipe 3. As mentioned above, if it is inconvenient to use an external pressure source that can stably provide air pressure in a certain medical environment, the air injection handle 7 can be made of air blower, air bag, syringe, etc. In this case, it is necessary to use the pressure gauge 5 to ensure the stability of the air pressure in the connecting pipe 3.
[0052] Among them, such as Figure 7 As shown, a one-way valve 6 is connected to the connecting pipe 3. As mentioned above, if it is inconvenient to use an external air pressure source that can stably provide air pressure in a certain medical environment, the air injection handle 7 can be an air blower, air bag, syringe, etc. Due to the instability of the air pressure source, the air pressure value in the connecting pipe 3 may exceed the required value, so the pressure can be regulated by the one-way valve 6. In one embodiment, the one-way valve 6 is a metering valve. When the air pressure in the connecting pipe 3 exceeds the threshold of the one-way valve 6, the one-way valve 6 automatically reduces the pressure.
[0053] The high-altitude simple cerebrospinal fluid pressure measuring kit comprises the cerebrospinal fluid pressure measuring device and a puncture needle, and the puncture needle is detachably connected with the one end of the measuring tube 1 away from the three-way pipeline.
[0054] The specific use mode and role of the embodiment are as follows: in the present application, the puncture needle is used for puncture in a non-standard atmospheric pressure environment, and the puncture needle is connected with the cerebrospinal fluid pressure measuring device after the puncture is successful; at this time, the measuring tube 1 is in communication with the atmosphere, and the cerebrospinal fluid is led out; at the same time, the air pressure in the air pressure compensation assembly is adjusted to a standard atmospheric pressure or a required atmospheric pressure value through the air injection handle 7 or an external air pressure source; the measuring tube 1 and the air pressure compensation assembly are communicated, so that the cerebrospinal fluid is in a standard atmospheric pressure environment, and the pressure value of the cerebrospinal fluid in the standard atmospheric pressure or the required atmospheric pressure is measured;
[0055] By using the method and the device, the cerebrospinal fluid pressure under the standard atmospheric pressure can be conveniently and quickly measured in different altitudes, and the intracranial pressure is reflected, and the problems that the measurement results of the cerebrospinal fluid pressure in different altitudes are affected by the atmospheric pressure, the measurement value in the high-altitude area is inaccurate, and the values in different altitudes cannot be standardized are effectively solved.
[0056] The above merely describes exemplary embodiments of the present application, but is not intended to limit the protection scope of the present application, and the protection scope of the present application is defined by the appended claims.
