Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a non-invasive portable intra-abdominal pressure detection device. Background Art

[0002] The intra-abdominal pressure of the human body is directly related to the functioning of various abdominal organs. Therefore, intra-abdominal pressure is an important indicator that can guide the diagnosis and treatment of critically ill patients. To alleviate the patient's pain, a device for detecting abdominal pressure outside the patient's body will be used under certain conditions.

[0003] For example, Chinese patent CN221730552U discloses an abdominal pressure detector, which is installed on the patient's abdomen through a belt, inflates the air bag through an air pump and a trachea, and then detects the abdominal pressure through an abdominal pressure sensor inside the belt.

[0004] However, the detector is installed on the user's abdomen via a strap. During the installation process, it is difficult to ensure that the strap is consistently tight to the user's abdomen. Therefore, even if the same amount of gas is injected into the airbag, it is difficult to ensure that the pressure exerted by the airbag on the user's abdomen is consistent, affecting the accuracy of the detection.

[0005] Based on this, the present invention designs a non-invasive portable intra-abdominal pressure detection device to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a non-invasive portable intra-abdominal pressure detection device.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A non-invasive portable intra-abdominal pressure detection device comprises a sleeve, a tension sensor and a binding assembly with a coarse adjustment function;

[0009] The outer end of the sleeve is connected to the cylinder in a limited sliding manner, and the cylinder and the sleeve are fixedly connected to the two ends of the return spring respectively; the binding assembly is equipped with an adjustment mechanism for finely adjusting the tension of the binding assembly, and the sleeve is installed on the binding assembly through a mounting structure;

[0010] Two sets of tension sensors for detecting the tension value of the binding assembly are symmetrically installed on both sides of the sleeve;

[0011] The adjusting mechanism comprises a guide assembly and an adjusting assembly. The guide assembly is mounted on the binding assembly, and the adjusting assembly is mounted on the guide assembly and the binding assembly.

[0012] Furthermore, the binding assembly includes a first elastic band, a second elastic band, a hook and a hanging ring. One end of the first elastic band is fixedly connected to one end of the tension sensor through a pull ring, and a group of hooks is fixedly installed on the other end of the first elastic band; each group of hooks is composed of a plurality of metal hooks uniformly distributed at equal intervals; one end of the second elastic band is fixedly connected to the other end of the tension sensor through a pull ring, and a plurality of groups of hanging rings are fixedly installed on the other end of the second elastic band at equal intervals; the hooks are snap-connected.

[0013] Furthermore, the guide assembly includes a mounting frame, a mounting plate and a guide wheel. The mounting plate is fixedly mounted on the outside of the mounting frame, and the guide wheel is symmetrically mounted on the inside of the mounting frame. The second elastic band is in contact with the inside of the guide wheel.

[0014] Furthermore, the adjustment assembly includes a movable wheel, an adjustment frame, a screw, a knob and a guide rod. The adjustment frame is located in the mounting frame, and the movable wheel is rotatably installed on the inner side of the adjustment frame, and the movable wheel is located between the two guide wheels; the second elastic band passes around one guide wheel and then passes around from the side of the movable wheel close to the adjustment frame, and then contacts the other guide wheel; a screw is rotatably installed on the middle part of the outer side of the adjustment frame, the screw is threadedly connected to the mounting plate, and the screw is fixedly connected to the knob after passing through the mounting plate; the guide rods are symmetrically fixedly installed on the outer side of the adjustment frame, and the guide rods are limitedly slidably connected to the mounting plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The sleeve and the cylinder are installed in a fixing assembly installed on the binding assembly through a connecting assembly, and then the binding assembly is tied to the user's abdomen and roughly adjusted so that the binding assembly is basically in contact with the user's pressing position, so that the device is installed on the user's abdomen through the binding assembly, and the inner end of the sleeve is in contact with the user's pressing position; the elastic force of the binding assembly is detected by a tension sensor; the value of the tension sensor is observed, and the adjustment mechanism is operated to accurately adjust the binding assembly so that the elastic force of the binding assembly is in a standard state; then the cylinder is pressed, and the return spring between the cylinder and the sleeve is compressed by 2 cm, thereby controlling the pressing force applied during detection and improving the accuracy of detection;

[0016] 2. The sleeve presses against the user's abdomen under the elastic force of the return spring, and then releases the cylinder; the user's intra-abdominal pressure rebounds, thereby driving the sleeve to rebound, and the sleeve drives the binding assembly to rebound. The rebound force of the binding assembly is detected by the tension sensor, thereby detecting the rebound force of the sleeve, and then detecting the user's intra-abdominal pressure; and after one test, there is no need to remove the binding assembly from the user's abdomen. The position of the sleeve and the cylinder can be quickly adjusted by the connecting assembly and the fixing assembly to perform another test, so that the device can quickly perform tests in multiple positions, improving the detection accuracy;

[0017] 3. The detection device is small in size, and the binding components can be rolled up or folded, making it easy to store and carry. BRIEF DESCRIPTION OF THE DRAWINGS
