Description

Technical Field

[0001] The utility model 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 testing method that involves injecting a contrast agent into blood vessels. Because X-rays cannot penetrate contrast agent, angiography exploits this property, diagnosing vascular lesions through the images produced by the contrast agent under X-rays. When performing venous angiography on a patient's lower limbs, due to the long limbs and varying physical conditions of different patients, some patients have very slow blood flow, preventing the contrast agent from reaching the required location in a timely manner. In these cases, manual extrusion is necessary to apply pressure to force the contrast agent back into the bloodstream, allowing the imaging equipment to scan the image. Clinically, it has been found that reliable backflow of the contrast agent can only be achieved through instantaneous, high-pressure extrusion. The force and timing of manual extrusion often fall short of requirements, often requiring multiple extrusions, which inevitably result in excessive X-ray exposure. CN 106512127 B discloses an angiography extruder. While addressing the technical issues described in the prior art, it still presents some issues, such as the illegal use and reuse of disposable, substandard extrusion bands, which are not genuine, and are therefore inferior. Utility Model Content

[0003] The purpose of the utility model 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 utility model to solve its technical problems is:

[0005] A lower limb X-ray angiography squeezer comprises: a squeezer host control circuit board formed of a single chip, with a host wireless communication module connected to the periphery, a disposable squeeze band for attaching to a patient's body, and an airbag pressure sensor connected to the squeeze band; an air pump motor connected to an air pump, the air pump outlet connected to a gas cylinder, a gas pressure sensor connected to the gas cylinder connected to the host control circuit board, the gas cylinder outlet connected to the inflation port of the squeeze band via an inflation solenoid valve, a deflation solenoid valve connected to the inflation solenoid valve outlet, the deflation solenoid valve, the inflation solenoid valve, and the air 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 controls pressure gear selection, extrusion control, and operating status display for the device host.

[0006] It is characterized in that an RFID reading and writing module is provided on the host control circuit board, which adopts radio frequency wireless communication to carry out contactless communication with the radio frequency electronic tag buried in the extrusion strap. The single-chip microcomputer identifies and reads and writes 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 cannot be identified and the extrusion strap device at the end of its life of the inflatable bag will prompt and cannot enter the extrusion working state.

[0007] The beneficial effects of the utility model are:

[0008] The microcontroller and RFID reader / writer module identify and read / write the unique ID of the radio frequency tag of the disposable compression strap, as well as the number of uses and usage time set in the radio frequency tag. If the disposable compression strap cannot be identified, the strapping device will indicate that the life of the disposable compression strap and the inflation bag has ended, and the compression operation state cannot be entered. This avoids the risk of compression strap airbag explosion and harm to patients due to illegal use of counterfeit, non-original, and inferior compression straps, repeated fatigue use beyond the number of times, and excessive fatigue use, as well as the risk of infectious diseases caused by repeated use. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0010] Figure 1 It is a principle block diagram of the utility model. DETAILED DESCRIPTION

[0011] like Figure 1 As shown, the utility model 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 to tie 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 cylinder 7, and a gas pressure sensor 4 connected to the gas cylinder is connected to the host control circuit board, and the gas cylinder 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 is provided with a remote control wireless communication module 14, and the remote control wireless communication module establishes wireless communication with the host wireless communication module, and the remote control selects the pressure gear and controls the squeezing, and displays the working status of the device host.

[0012] The present invention also includes an RFID reading and writing module on the host control circuit board, which communicates with the electronic tag 11 embedded in the disposable squeeze band 10. The single-chip microcomputer and the RFID reading and writing module identify and read and write 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, and monitor the use. The squeeze band that cannot be identified and the squeeze band device at the end of the life of the inflation bag will be prompted and cannot enter the squeeze working state, thereby avoiding the risk of injury to the patient caused by the illegal use of counterfeit, non-original and inferior squeeze bands, repeated fatigue use beyond the number of times and overtime fatigue use, and the risk of infectious diseases caused by repeated use.

[0013] The working process of this embodiment is as follows:

[0014] 1. After the host and remote control are successfully powered on and connected, place the disposable squeeze band close to the host reader / writer, identify the ID, write the first use time, and read the number of squeezes and the first use time. After that, the compressor starts to automatically pre-inflate the squeeze band. If the number of squeezes read is 0 or the current use time and the first use time are more than 8 hours apart, the device cannot enter the squeeze working state.

[0015] Second, the remote control is designed with 5 gear buttons. 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 and deflation processes;

[0016] The remote control controls the compression strap to inflate or deflate once, and the number of squeezes is reduced by one. When the number of squeezes reaches zero, the remote control prompts "The life of the air bag has ended."
