Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a lower limb X-ray angiography squeezer. Background Art

[0002] Angiography is an interventional detection method, in which a developer is injected into a blood vessel. Since X-rays cannot penetrate the developer, angiography utilizes this property to diagnose vascular lesions through the image displayed by the developer under X-rays. When performing venous angiography on the patient's lower limbs, due to the long limbs and different physical conditions of different patients, the blood flow rate of some patients is very slow, causing the developer to fail to reach the position where it needs to be developed in time. At this time, artificial squeezing has to be used to apply pressure to make the developer flow back so as to scan the imaging of the developing equipment. It is found in clinical practice that only when squeezing with instantaneous high pressure can the developer be reliably refluxed. The strength and timing of artificial squeezing often cannot meet the requirements, and multiple squeezing is often required, which inevitably exposes the developer to too much X-rays. CN 106512127 B discloses a contrast squeezer. Although it solves the technical problems described in the above-mentioned prior art, it still has some problems such as the illegal use and reuse of disposable squeezing bands that are not original inferior products. Summary of the invention

[0003] The purpose of the present invention is to provide a lower limb X-ray angiography squeezer, which can instantly squeeze the part of the patient that needs to be developed, so that the developer can flow back normally, ensuring the timeliness and accuracy of angiography, while avoiding the illegal use and reuse of disposable squeezing bands that are non-original and inferior products.

[0004] The technical solution adopted by the present invention to solve the technical problem is: A lower limb X-ray radiography squeezer, comprising: a squeezer host control circuit board formed by a single chip, a host wireless communication module connected to the periphery, a disposable squeeze band used to be attached to a patient's body, and an airbag pressure sensor connected to the squeeze band; an air pump motor connected to an air pump, an outlet of the air pump connected to a gas storage bottle, a gas storage pressure sensor connected to the gas storage bottle connected to the host control circuit board, an outlet of the gas storage bottle connected to an inflation port of the squeeze band through an inflation solenoid valve, a deflation solenoid valve connected to an outlet of the inflation solenoid valve, and the deflation solenoid valve, the inflation solenoid valve and the inflation pump motor connected to the host control circuit board; a host wireless communication module and a remote control wireless communication module, which together constitute wireless communication between the host and the remote control, and the remote control performs pressure gear selection and extrusion control and working status display on the device host; The main engine control circuit board is provided with an RFID reading and writing module, which adopts radio frequency wireless communication to carry out contactless communication with the radio frequency electronic tag buried in the extrusion strap, and uses the single-chip microcomputer to identify and read and write the unique ID of the radio frequency electronic tag of the disposable extrusion strap, the number of uses and the usage time set in the radio frequency electronic tag. The extrusion strap device prompts the extrusion strap that cannot be identified and the extrusion bag that has reached the end of its life, and cannot enter the extrusion working state.

[0005] The beneficial effects of the present invention are: The MCU and RFID read / write module can be used to identify and read / write monitor the unique ID of the RFID tag, the number of uses and the use time set in the RFID tag. If the disposable RFID tag cannot be identified, the strapping device will prompt that the life of the disposable RFID tag and the inflation bag has ended, and the RFID tag cannot enter the extrusion working state. This can avoid the risk of injury to patients caused by the explosion of the RFID tag airbag due to illegal use of counterfeit, non-original and inferior RFID tags, repeated fatigue use beyond the number of times, and overtime fatigue use, as well as the risk of infectious diseases caused by repeated use. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The present invention is further described below in conjunction with the accompanying drawings and embodiments: Figure 1 It is a principle block diagram of the present invention. DETAILED DESCRIPTION

[0007] like Figure 1 As shown, the present invention provides a lower limb X-ray angiography squeezer, comprising: a squeezer host control circuit board 2 composed of a single chip, a host wireless communication module 12 is connected to the periphery of the host control circuit board, and is used for tying a disposable squeezing band 10 attached to the patient's body, and an airbag pressure sensor 3 connected to the squeezing band is connected to the host control circuit board; an air pump motor 5 is connected to an air pump 6, and an air pump outlet is connected to a gas storage bottle 7, and a gas storage pressure sensor 4 connected to the gas storage bottle is connected to the host control circuit board, and the gas storage bottle outlet is connected to the inflation port of the squeezing band 10 through an inflation solenoid valve 8, and a deflation solenoid valve (pressure relief valve) 9 is connected to the outlet of the inflation solenoid valve 8, and the deflation solenoid valve 9, the inflation solenoid valve 8 and the inflation pump motor 5 are connected to the single chip microcomputer; a remote control wireless communication module 14 is provided in the wireless remote control, and the remote control wireless communication module and the host wireless communication module form wireless communication, and the remote control performs pressure gear selection and squeezing control and working status display on the device host.

[0008] The present invention also includes an RFID reading and writing module on the host control circuit board, which communicates with the electronic tag 11 buried in the disposable squeeze band 10, and identifies and reads and writes the unique ID of the radio frequency electronic tag of the squeeze band, the number of uses and the usage time set in the radio frequency electronic tag through the single-chip microcomputer and the RFID reading and writing module. The squeeze band device prompts that the squeeze band that cannot be identified and the squeeze band at the end of the life of the inflation bag cannot enter the squeeze working state, thereby avoiding the risk of injury to the patient caused by the explosion of the squeeze band airbag due to illegal use of counterfeit non-original inferior squeeze bands, repeated fatigue use beyond the number of times and overtime fatigue use, and the risk of infectious disease transmission due to repeated use.

[0009] The working process of this embodiment is as follows: 1. The host and the remote control are successfully powered on and connected. The disposable squeezing strap is placed close to the host reader, the ID is identified, the first use time is written, and the number of squeezing times and the first use time are read. After that, the compressor starts to automatically pre-inflate the squeezing strap; if the number of squeezing times is 0 or the current use time and the first use time exceed 8 hours, the device cannot enter the squeezing working state.

[0010] Second, there are 5 gear buttons designed on the remote control. Doctors can select the corresponding gears 1 to 5 according to clinical needs to squeeze the gastrocnemius muscle of the patient's lower limbs. The squeezing operation is divided into inflation process and deflation process; The remote control controls the squeezing strap to inflate or deflate once, and the squeezing times decrease by one. When the squeezing times reaches zero, the remote control prompts "The life of the inflatable bag has ended".
