In the related art, the pressure of the liquid in the infusion tube is generally measured by a pressure measuring device of the medical line. The pressure measuring device of the traditional medical pipeline indirectly measures the pressure of liquid by detecting the expansion contact force of the soft pipe wall. But the measurement results have errors due to the thickness and elasticity of the tube wall.
In view of this, referring to fig. 1 and 2, the present invention provides an embodiment of a pressure measurement device for a medical line, which is generally used to measure the pressure of a liquid in a medical line. For example, the medical tubing may measure the pressure in the infusion tube. In the following embodiments, the pressure of a fluid in a medical line will be described mainly by way of example, and other cases where a pressure measuring device for a medical line is required will be described with reference to the embodiments.
Referring to fig. 1 and 2, in an embodiment of a pressure measuring apparatus for a medical line according to the present invention, the pressure measuring apparatus for a medical line includes a main line 100 and a pressure sensor 200, wherein the main line 100 is provided with a pressure measuring line 110 communicating with the main line 100; the pressure sensor 200 is mounted at an end of the pressure measuring line 110 remote from the main line 100.
In particular, in the present embodiment, the main pipe 100 and the pressure measuring pipe 110 are integrally formed, which is advantageous in enhancing the sealing property of the connection of the main pipe 100 and the pressure measuring pipe 110, and in addition, the integral formation of the main pipe 100 and the pressure measuring pipe 110 is advantageous in enhancing the strength of the main pipe 100 and the pressure measuring pipe 110. Of course, in other embodiments, main line 100 and pressure line 110 may be manufactured separately and then assembled together, thereby increasing the portability of the pressure measurement device of the medical line.
It can be appreciated that, since the main pipeline 100 is connected with the pressure measuring pipeline 110, when the liquid flows through the main pipeline 100, the liquid will squeeze the air to the pressure measuring pipeline 110, and the air in the pressure measuring pipeline 110 will transfer the pressure to the pressure sensor 200 after being squeezed, so that the pressure sensor 200 can measure the pressure of the air, that is, the pressure sensor 200 can measure the pressure of the liquid in the main pipeline 100, and thus, the pressure sensor 200 can measure the pressure of the liquid in the main pipeline 100 by taking the air as a medium, thereby improving the accuracy of measuring the pressure of the liquid in the main pipeline 100. It should be noted that the pressure of the liquid in the main line 100 measured by the pressure sensor 200 is the pressure of the liquid in the junction of the main line 100 and the pressure measuring line 110.
Secondly, a section of air column is formed between the liquid at the joint of the main pipeline 100 and the pressure measuring pipeline 110 and the pressure sensor 200, and the air column is positioned between the pressure measuring pipelines 110, so that the air column can not only play a role in conducting force, but also avoid the pollution of the liquid by the pressure sensor 200, and has the function of isolating the liquid, thereby improving the precision of measuring the liquid pressure on the premise of not influencing the liquid conveying.
In general, the main line 100 is a medical infusion line and a catheter line, the main line 100 is connected to a patient, so that the pressure of the liquid in the main line 100 is not too high, and since the liquid in the main line 100 presses the air in the pressure measuring line 110, only a small portion of the liquid in the main line 100 flows into the pressure measuring line 110, so that the pressure sensor 200 can measure the pressure of the air, and at the same time, the pressure sensor 200 is not damaged after contacting the liquid.
In addition, since the pressure sensor 200 measures the pressure at the junction of the main line 100 and the pressure measuring line 110 by measuring the pressure in the pressure measuring line 110, the junction of the pressure sensor 200 and the pressure measuring line 110 needs to maintain good sealability.
According to the technical scheme, the pressure measuring device is provided with a main pipeline 100 and a pressure sensor 200, wherein the main pipeline 100 is provided with a pressure measuring pipeline 110 communicated with the main pipeline 100, and the pressure sensor 200 is arranged at one end, far away from the main pipeline 100, of the pressure measuring pipeline 110; thus, when the liquid flows through the main pipeline 100, the liquid presses the air to the pressure measuring pipeline 110, and the air in the pressure measuring pipeline 110 is pressed to transmit the pressure to the pressure sensor 200, so that the pressure sensor 200 can measure the pressure of the air, that is, the pressure sensor 200 can measure the pressure of the liquid in the junction of the main pipeline 100 and the pressure measuring pipeline 110, so that the pressure sensor 200 can measure the pressure of the liquid in the main pipeline 100 by taking the air as a medium, thereby improving the accuracy of measuring the pressure of the liquid in the main pipeline 100.
In one embodiment, the diameter of the pressure line 110 is smaller than the diameter of the main line 100. Specifically, the diameter of the pressure measuring pipeline 110 is smaller than that of the main pipeline 100, which is beneficial to saving the accommodation space. In addition, the diameter of the pressure measuring pipeline 110 is smaller than that of the main pipeline 100, which is beneficial to shortening the distance between the liquid in the main pipeline 100 and the pressure sensor 200, so that the fluctuation of air in the pressure measuring pipeline 110 is increased, and the accuracy of the pressure measuring device of the medical pipeline is further improved.
In one embodiment, the pressure measuring line 110 is configured to be curved. Specifically, the pressure measurement pipeline 110 is provided in a curved manner, so that the pressure sensor 200 is prevented from being corroded by the liquid, and the pressure sensor 200 is prevented from being corroded by the liquid, so that a protective barrier is provided for the pressure sensor 200, and the pressure sensor 200 is further facilitated to be included.
As for the degree of bending of the pressure measurement line 110, the pressure measurement line 110 may be provided in a wavy shape. For example, the end of the pressure measuring line 110 near the main line 100 is provided in a curved shape; or one end of the pressure measuring pipeline 110, which is close to the pressure sensor 200, is arranged in a bending way; alternatively, the pressure measuring line 110 may be curved as a whole, and is specifically selected according to practical situations, which is not limited herein.
In one embodiment, the pressure measuring pipeline 110 is provided with a water storage container 300, and the water storage container 300 is positioned between the junction of the main pipeline 100 and the pressure measuring pipeline 110 and the pressure sensor 200. Specifically, the pressure measuring pipeline 110 is provided with a water storage container 300, and the water storage container 300 can be an external device, or a water receiving tank can be arranged at a position, close to the pressure sensor 200, of the pressure measuring pipeline 110. It should be noted that, when the water storage container 300 is an external device, the tightness between the water storage container 300 and the pressure measuring pipeline 110 should be ensured.
In an embodiment, the pressure measurement device of the medical pipeline further includes an empty pipe detection module 600, where the empty pipe detection module 600 is disposed on the pressure measurement pipeline 110 and is electrically connected to the control module 500, so as to be used for detecting the medium in the pressure measurement pipeline 110. Further, in an embodiment, the empty pipe detection module 600 is any one of an ultrasonic sensor, a photoelectric sensor or a capacitive sensor. Specifically, the empty pipe detection module 600 is disposed on the pressure measurement pipeline 110, and can detect whether there is a liquid in contact with the pressure sensor 200, thereby protecting the pressure sensor 200.
In one embodiment, the empty pipe detection module 600 is located at the junction of the main pipe 100 and the pressure measuring pipe 110 and between the water storage container 300. Specifically, the empty pipe detection module 600 may alert the user that there is liquid coming into contact with the pressure sensor 200, thereby providing a barrier to protect the pressure sensor 200.
In an embodiment, the pressure measuring device of the medical pipeline further comprises a driving pump 400, the driving pump 400 is disposed on the main pipeline 100, and the connection between the main pipeline 100 and the pressure measuring pipeline 110 is located at the output side of the pump. Specifically, the physician may adjust the operation of the drive pump 400 based on the data measured by the pressure sensor 200.
In an embodiment, the pressure measurement device of the medical line further includes a control module 500, and the control module 500 is electrically connected to the pressure sensor 200 and the driving pump 400, so that the control module 500 controls the operation of the control valve 800 according to the signal transmitted by the pressure sensor 200.
In particular, the types of the driving pump 400 are numerous, and for example, the driving pump 400 may be an infusion pump, a nutrition pump, or a peristaltic pump, and is specifically selected according to the actual situation, which is not limited herein.
When the pressure measuring device using the medical line is operated, since the driving pump 400 includes a motor, the flow rate of the output end of the main line 100 is controlled by the motor. The pressure sensor 200 is installed at one end of the pressure measuring pipeline 110 far away from the main pipeline 100, and can measure the pressure of the liquid at the connection part of the pressure measuring pipeline 110 and the main pipeline 100, and then the pressure sensor 200 can transmit the measured data to the control module 500, so that the control module 500 obtains the measured value, wherein the control module 500 is set with a predetermined value, and the control module 500 can control the driving pump 400 to work according to the set predetermined value.
In one embodiment, the pressure detection of the medical tubing further comprises an alarm module 700, the alarm module 700 being electrically connected to the control module 500. Specifically, since the predetermined value is set in the control module 500, the control module 500 can compare the measured value with the predetermined value, and if the measured value is not within the predetermined value, the control module 500 controls the alarm module 700 to alarm, thereby reminding the doctor or nurse to perform the operation. In addition, the control module 500 may further determine that there is a liquid in contact with the pressure sensor 200 according to the working condition of the empty pipe detection module 600, and if the empty pipe detection module 600 detects that there is a liquid, the control module 500 will control the alarm module 700 to alarm, so that the worker processes the liquid, and further protects the pressure sensor 200.
Intravenous infusion is one of the most commonly used clinical treatments, and is a common drug delivery treatment technique for the care profession. Clinically, the infusion rate should be matched with the appropriate infusion rate according to the condition of patients. Infusion is too fast, which may lead to poisoning and more severe to oedema and heart failure; too slow infusion may result in insufficient dosage or excessive infusion time, affecting treatment and adding unnecessary burden to the patient and care staff, so the pressure measuring device of the medical line reduces more burden to the patient and care staff.
Secondly, the common infusion apparatus can not automatically alarm on accidental faults such as bubbles, blockage and the like in the infusion process and the infusion completion, and can not technically cut off an infusion passage, so that adverse effects are generated, and further, blood diversion or other effects are avoided. The pressure measuring device of the medical pipeline can accurately control the flow rate and the flow rate of the liquid medicine conveyed by the infusion pump and can alarm abnormal conditions in the infusion process, thereby being beneficial to reducing the working strength of medical care, improving the safety, the accuracy and the working efficiency and further improving the nursing level.

The venous pressure is the pressure of the fluid in the junction of main line 100 and pressure measurement line 110, and the pressure of the fluid column between the junction of main line 100 and pressure measurement line 110 and the infusion needle. The liquid column pressure is the pressure from the connection of the main pipeline 100 and the pressure measuring pipeline 110 to the liquid column height between the infusion needle, and the height from the connection of the main pipeline 100 and the pressure measuring pipeline 110 to the liquid column between the infusion needle is H1.
In an embodiment, the pressure measurement device of the medical pipeline further includes a control valve 800, the control valve 800 is disposed on the main pipeline 100, and a connection between the pressure measurement pipeline 110 and the main pipeline 100 is located at an input end of the main pipeline 100.

The pressure sensor 200 is installed at one end of the pressure measuring pipeline 110 far away from the main pipeline 100, and can measure the pressure of the liquid at the connection position of the pressure measuring pipeline 110 and the main pipeline 100, and then the pressure sensor 200 can transmit the measured data to the control module 500, so that the control module 500 obtains the measured value, wherein the control module 500 is set with a predetermined value, and the control module 500 can control the control valve 800 to operate according to the set predetermined value.
