Description

Technical Field

[0001] The present disclosure relates to the technical field of detection equipment, and in particular to a medical socks detection device. Background Art

[0002] Medical hosiery, also known as compression stockings or medical elastic stockings, is a type of garment designed to promote venous blood return. Typically made of elastic materials such as Lycra and nylon, they apply graduated pressure to the legs, extending from the ankle upwards. This helps reduce pressure on the leg veins, preventing and treating conditions like varicose veins.

[0003] The prior art CN209372278U discloses a compression stocking tester, including a mold column, a column, a driving mechanism, and several pressure sensors. The mold column is provided with a accommodating cavity, and the outer wall of the mold column is provided with several pressure testing points along its length direction. The pressure testing points are connected to the accommodating cavity. The column is provided in the accommodating cavity, and the pressure sensors are provided on the column corresponding to the pressure testing points. The driving mechanism is fixed in the accommodating cavity, and the driving mechanism is connected to the column. The driving mechanism drives the column to move so that the pressure sensor passes through the pressure testing point. The technical data of the pressure socks at different positions on the surface of the mold column can be accurately obtained through the pressure sensor, thereby realizing accurate measurement of the compression socks.

[0004] The above patent still has the following defects:

[0005] Because the aforementioned patent uses a driving mechanism to drive the pressure sensor to transmit the pressure test point, so that the pressure sensor contacts the compression stocking / medical stocking and detects the pressure of the compression stocking / medical stocking, the driving mechanism usually has a minimum stroke limit, which makes it impossible to use the minimum range of the pressure sensor, and the pressure sensor cannot accurately measure the pressure of the compression stocking / medical stocking.

[0006] At the same time, since the above-mentioned compression stocking tester drives the pressure sensor through the pressure test point through the driving component to obtain the pressure of the contact part between the pressure test point and the compression stocking, the measured area of ​​the point is only based on the range that the sensing end of the pressure sensor can cover, and it is impossible to measure the pressure of a larger area near the pressure measurement point.

[0007] In summary, the above patents cannot accurately detect the pressure of compression stockings / medical stockings and a single pressure test point can only measure the pressure in the area of ​​the sensing end of the pressure sensor. Utility Model Content

[0008] In order to solve the problems existing in the above-mentioned prior art, the present disclosure aims to provide a medical socks detection device to solve the technical problem that the prior art cannot accurately detect the pressure of compression socks / medical socks.

[0009] The medical socks testing device disclosed herein comprises a mold column and a plurality of pressure sensing components. The mold column is provided with a receiving cavity inside, and the outer wall of the mold column is provided with a plurality of pressure testing points, and the plurality of pressure testing points are connected to the receiving cavity.

[0010] The pressure sensing assembly includes a pressure sensor and an airbag. The pressure sensor includes a sensing end and a transmission line. The sensing end is arranged in the airbag. Several pressure sensing assemblies are correspondingly arranged at the pressure test points and connected to the mold column.

[0012] The connecting member is formed with a connecting seat adapted to the pressure sensing assembly at the portion where it is connected to the pressure sensing assembly. The connecting seat is annular, and connecting structures are symmetrically formed on both sides of the connecting seat. The connecting structure includes two support plates and a locking hook.

[0013] The two support plates are arranged on both sides of the locking hook; an accommodating hole facing the support plate is formed at one end of the locking hook close to the connecting seat, the accommodating hole passes through the locking hook, a torsion spring is arranged in the accommodating hole, and the end of the torsion spring is connected to the support plate;

[0014] The end of the locking hook away from the connecting seat is a hook portion; the mold column is provided with a locking plate extending along the direction of the accommodating cavity at the pressure test point, and a locking groove adapted to the locking hook is formed on the locking plate;

[0015] The torsion spring is configured to ensure that the locking hook always has a movement tendency to engage with the locking groove.

[0016] Preferably, the medical socks detection device further comprises a base, the base comprising a base body and a connecting portion, the base body and the connecting portion are connected, and the top of the connecting portion is connected to the mold column.

[0017] Preferably, a ventilation hole is provided at one location on the side surface of the connecting portion, and a plurality of through holes communicating with the accommodating cavity are provided at another location on the side surface of the connecting portion, and the transmission line extends outside the mold column through the through holes.

[0021] Preferably, the number of the pressure test points is seven.

[0022] The advantages of the medical socks detection device disclosed in the present invention are:

[0023] The present disclosure utilizes the coordination of the airbag and the pressure sensor, eliminating the need for a drive assembly to drive the pressure sensor through the pressure test point. This reduces the number of drive assembly components required, thereby avoiding the limitation of the minimum stroke of the drive assembly and enabling the use of the minimum range of the pressure sensor to more accurately measure the pressure of the medical socks.

[0024] At the same time, the present disclosure cooperates with the airbag and the pressure sensor so that after the airbag is inflated, the pressure sensor can sense the change in the air pressure inside the airbag, thereby enabling the pressure sensor to detect the pressure at any point within the coverage area of ​​the airbag.

DETAILED DESCRIPTION

[0031] like Figure 1 As shown, a medical socks testing device disclosed herein includes a mold column 1 and a plurality of pressure sensing components 2. A receiving cavity is provided inside the mold column 1, and a plurality of pressure testing points are provided on the outer wall of the mold column 1. The plurality of pressure testing points are connected to the receiving cavity.

[0032] The pressure sensing assembly 2 includes a pressure sensor and an airbag. The pressure sensor includes a sensing end and a transmission line. The sensing end is arranged in the airbag. Several pressure sensing assemblies 2 are correspondingly arranged at pressure test points and connected to the mold column 1.

[0033] In one embodiment of the present disclosure, the mold column 1 is designed to resemble the lower limbs of the human body, and can be divided into a thigh, calf, and foot. Pressure testing points are provided on each of the thigh, calf, and foot. Specifically, several pressure testing points are spaced apart on one side of the leg, and at least one pressure testing point is provided on the side of the foot away from the leg.

[0034] The mold column 1 can be opened on the side where the pressure test point is not set, and a baffle can be detachably installed to prevent the internal accommodating cavity from being exposed. At the same time, when the interior of the accommodating cavity needs to be inspected, the baffle can be opened for inspection.

[0035] For example, the pressure sensor disclosed herein may be a pressure sensor of model LE-080 or model XCQ-062 manufactured by Kulite.

[0036] Furthermore, the medical socks detection device further includes a connector 3 , and the pressure sensing assembly 2 is detachably connected to the mold column 1 via the connector 3 .

[0037] Specifically, if Figure 2 and Figure 3 As shown, in one embodiment of the present disclosure, a connecting member 3 is formed with a connecting seat 31 adapted to the pressure sensing assembly 2 at the portion where the connecting member 3 is connected to the pressure sensing assembly 2. The connecting seat 31 is annular, and connecting mechanisms 32 are symmetrically formed on both sides of the connecting seat 31. The connecting mechanism 32 includes two support plates 321 and a locking hook 322.

[0038] Two support plates 321 are provided on both sides of the locking hook 322; an end of the locking hook 322 close to the connecting seat 31 is formed with a receiving hole facing the support plate 321, the receiving hole passes through the locking hook 322, and a torsion spring is provided in the receiving hole, the end of the torsion spring is connected to the support plate 321;

[0039] The end of the locking hook 322 away from the connecting seat 31 is a hook portion; the mold column 1 is provided with a locking plate extending in the direction toward the accommodating cavity at the pressure test point, and a locking groove is formed on the locking plate to match the locking hook 322;

[0040] The torsion spring is configured to ensure that the locking hook 322 always has a movement tendency to engage with the locking groove.

[0041] In order to facilitate the connection between the connection line and the external testing equipment, an opening is made at the bottom of the mold column 1.

[0042] The coordination process of the above structure is as follows:

[0043] The airbag of the pressure sensing assembly 2 is installed on the connecting seat 31 of the mounting connector 3. The connecting seat 31 is annular, and the airbag abuts against the ring of the connecting seat 31. The transmission line of the pressure sensor passes through the hollow part of the connecting seat 31 and enters the mold column 1. The connector 3 is placed on the pressure test point and inserted toward the accommodating cavity. When the locking hook 322 is engaged with the locking groove, it means that the pressure sensing assembly 2 and the connector 3 are successfully installed on the mold column 1. When the pressure sensing assembly 2 needs to be removed, open the baffle of the mold column 1, press the locking hook 322 toward the center of the connecting seat 31 in the accommodating cavity so that the hook part of the locking hook 322 is out of the locking groove, and then push the connector 3 away from the mold column 1 to remove the pressure sensing assembly 2.

[0044] Furthermore, in order to ensure the stability of the detection device, the medical sock detection device also includes a base 4, which includes a base body 41 and a connecting part 42, the base body 41 and the connecting part 42 are connected, and the top of the connecting part 42 is connected to the mold column 1.

[0045] Specifically, the connecting portion 42 and the mold column 1 can be connected through matching threads, or holes can be opened at corresponding positions and connected through conventional screws and nuts. The specific connection method can be selected according to actual conditions.

[0046] Furthermore, because the transmission lines inside the accommodating cavity generate heat during data transmission, although the bottom of the mold column 1 is open, since the mold column 1 must be mounted on the base 4 during operation, the opening is covered by the base 4, preventing effective heat dissipation. To prevent overheating inside the accommodating cavity, a vent hole 421 is provided at one location on the side of the connecting portion 42; and several through-holes 422 are provided at another location on the side of the connecting portion 42, connecting to the accommodating cavity. The transmission lines extend through these through-holes 422 to the outside of the mold column 1.

[0047] More specifically, a cooling fan may be provided near the vent hole 421 to speed up the heat dissipation.

[0048] Furthermore, since the medical sock testing device described herein measures pressure through the coordination of an airbag and a pressure sensor, inflation of the airbag requires corresponding components. Therefore, the device also includes an inflation assembly, which includes an inflation pump, a valve body, an air tube, and an inflation branch pipe. One end of the air tube is connected to the airbag, while the other end extends through through-hole 422 to the outside of mold column 1, where it connects to the inflation branch pipe via the valve body. The inflation branch pipe is then connected to the inflation pump.

[0049] Specifically, the airbag is connected to the valve body via an air tube, which is connected to the inflation branch pipe, which is connected to the inflation pump. When the inflation pump is activated, gas enters the airbag through the inflation branch pipe, filling the airbag. A pressure sensor detects the air pressure inside the airbag, ultimately measuring the pressure of the medical sock.

[0050] After the test is completed, the trachea is pulled out. Since the airbag is connected to the trachea, the gas in the airbag is discharged directly from the trachea, and there is no need to set up accessories such as an exhaust pump to deflate the air.

[0051] Furthermore, in order to more quickly control the inflation component and the pressure sensing component 2 , the medical socks detection device further includes a controller, which is electrically connected to the inflation component and the pressure sensing component 2 .

[0052] Specifically, the controller may be a conventional controller such as a PLC (Programmable Logic Controller) or an MCU (Microcontroller), and the specific controller may be selected according to the actual situation.

[0053] In one embodiment of the present disclosure, a PLC (programmable logic controller) is selected. The PLC (programmable logic controller) has a USB port and an Ethernet port, which can be connected to a smart terminal, so that the control instructions can be adjusted in real time. The smart terminal can also receive measurement data in real time and process it in real time.

[0054] Furthermore, in order to facilitate the installation of the trachea and the placement of the inflation component, the medical socks detection device also includes a shell 5, and the inflation component and the controller are both arranged in the shell 5; at least one button 51 is provided on the outside of the shell 5, and at least one button 51 is electrically connected to the controller.

[0055] Specifically, a plurality of connection ports are provided on one side of the shell 5, and one end of the valve body connected to the air pipe passes through the connection port and is exposed outside the shell 5, so that the air pipe can be connected to the valve body from the connection port. The number of connection ports can be adapted according to the number of pressure test points set on the mold column 1. For example, if there are a total of 7 pressure test points, 7 connection ports can be opened. In order to avoid failure of one or several of the connection ports and make them unusable, 10 connection ports can be opened, three of which are used as spares. Even if a connection port fails, the spare connection port can be connected to continue testing.

[0056] At least one case is also provided on the outside of the housing 5. In one embodiment of the present disclosure, Figure 4 As shown, a button 51 is provided on the front, and the button 51 is electrically connected to the controller and is used to turn on or off the controller.

[0057] At the same time, a number of USB interfaces are opened on the back of the housing 5, and the USB ports of the PLC (Programmable Logic Controller) are exposed therefrom, making it convenient for the staff to connect the PLC (Programmable Logic Controller) and the mobile terminal.

[0058] Furthermore, there are seven pressure test points. Three pressure test points are set at intervals on the thigh, three pressure test points are set at intervals on the calf, and one pressure test point is set on the foot. The three pressure test points on the thigh and the three pressure test points on the calf are set on the same side; the one pressure test point on the foot is set at the heel.

[0059] like Figure 4 As shown, the test steps are described using a computer as an intelligent terminal as an example. The computer is installed with the corresponding detection software. The test steps are as follows:

[0060] (1) Connect the air pipe to the valve body, press the button 51 on the housing 5 to turn on the controller, and connect the controller to the computer via a USB data cable;

[0061] (2) Open the detection software. After entering the software, the inflation component will automatically inflate the airbag to calibrate the pressure and reduce the detection error;

[0062] (3) Put the medical socks on the mold column 1, and do not pull any part of the compression socks hard;

[0063] (4) After the medical socks are put on, click the "Start" button on the software, and the inflation component inflates the airbag. At the same time, the pressure sensor detects the internal pressure of the airbag in real time and transmits the pressure data to the software;

[0064] (5) When the airbag just pushes up the medical socks and the pressure value measured by the pressure sensor remains unchanged after 2 to 3 seconds, it is confirmed to be the pressure of the medical socks. During the whole process, the data of the pressure sensor can be automatically displayed on the computer software.
