Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ventilation devices, in particular to a radiation-proof ventilation and pressure relief device and application thereof. BACKGROUND

[0002] Medical diagnostic X-ray equipment is equipment that uses X-rays as the basis for detection and diagnosis, and controls X-rays for radiological examination of human tissues, which can help doctors determine the specific condition of patients. Common medical diagnostic X-ray equipment includes CT, DSA, DR, digital gastrointestinal machine, and breast molybdenum target machine. Since the X-rays emitted by the above-mentioned equipment pose a certain radiation hazard to the surrounding population, the machine room must take appropriate shielding measures. Since the above-mentioned equipment is relatively expensive, ranging from tens of thousands to several million yuan, the fire safety of the machine room often uses heptafluoro-propane as a fire extinguishing agent. Heptafluoro-propane has good fire extinguishing effect and strong resistance to rekindling. It is colorless, odorless, low-pollution, low-residue, and dust-free, making it convenient to handle post-disaster items, and more suitable for use in important places such as libraries, archives, and important machine rooms.

[0003] With the rapid development of fire safety technology, fire safety facilities are increasingly becoming more and more integrated. Once the fire alarm is triggered in the machine room, the heptafluoro-propane extinguishing agent will spontaneously spray and quickly fill the entire fire extinguishing area. In the case of a triggered fire alarm in a medical diagnostic X-ray machine room, if the personnel inside the machine room do not escape in time, the heptafluoro-propane under strong pressure may cause suffocation and death of the personnel inside the machine room.

[0023] Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Medical diagnostic X-ray equipment is a device that uses X-rays as a basis for detection and diagnosis, and controls X-rays for radiological examination of human tissues, which can help doctors judge the specific condition of patients. Common medical diagnostic X-ray equipment includes CT, DSA, DR, digital gastrointestinal machine, breast molybdenum target machine, etc. Because the X-rays emitted by the above-mentioned equipment have certain radiation hazards to the surrounding population, the machine room must take appropriate shielding measures. Because the above-mentioned equipment is relatively expensive, ranging from tens of thousands to several million, the fire safety of the machine room often uses heptafluoro-propane as a fire extinguishing agent. With the vigorous development of fire safety technology, fire safety facilities are becoming more and more linked. Once the fire alarm is triggered in the machine room, the heptafluoro-propane extinguishing agent will spontaneously spray out and quickly fill the entire fire extinguishing area. If the personnel in the machine room do not escape in time under the condition of triggering the fire alarm of the medical diagnostic X-ray machine room, the heptafluoro-propane under strong pressure may cause suffocation and death of the personnel in the machine room.

[0025] The present application provides a radiation-proof ventilation and pressure relief device, Fig. 1 The present application provides a radiation-proof ventilation and pressure relief device, Fig. 2 The present application provides a radiation-proof ventilation and pressure relief device, Fig. 3A structure diagram of a lead covering pressure relief port is shown in an embodiment of the present application, as shown in the figure Figs. 1-3 As shown, the radiation-proof ventilation and pressure relief device comprises: a ray machine room 1; a control room 7 located on one side of the ray machine room 1; a pressure relief port 2 opened on the wall of the ray machine room 1 adjacent to the control room 7; a window frame 3 fixedly connected around the pressure relief port 2; a window baffle 4; and a buckle 5 installed on both sides of the window frame 3 for fixing the window baffle 4 on the window frame 3.

[0026] The medical diagnostic X-ray equipment uses X-rays as the basis for detection and diagnosis, and controls X-rays for radiological examination of human tissues. It can help doctors determine the specific condition of the patient. The X-rays emitted by the equipment pose a certain radiation hazard to the surrounding population, so the ray machine room 1 must take appropriate shielding measures. When the human tissue is being examined, the medical diagnostic X-ray equipment is controlled by the control room for corresponding examination. When an emergency such as a fire occurs, the heptachloropropane extinguishing agent will spontaneously spray and quickly fill the entire fire extinguishing area. Under the condition of triggering the fire alarm, the ray machine room 1 will form a closed space around the room to prevent the X-rays emitted by the equipment from causing a certain radiation hazard to the surrounding population. If the personnel in the room do not escape in time, the heptachloropropane under high pressure may cause suffocation and death of the personnel in the room. By opening the pressure relief port 2 on the wall of the ray machine room 1 adjacent to the control room 7, and installing the window baffle 4 on the pressure relief port 2, when an emergency such as a fire occurs, the pressure relief port 2 can circulate air inside and outside, and will not cause suffocation or death of the personnel in the room due to the closed space.

[0027] Preferably, the pressure relief device further comprises: a lead page 6 arranged on the window frame 3.

[0028] Preferably, the window baffle 4 is covered on the lead page 4, and the window baffle 4 is used for protecting against radiation hazards. Covering the window baffle 4 on the lead page 6 can prevent gaps between the lead page 6 and the window baffle 4, and can better play a protective effect against radiation.

[0029] Preferably, the pressure relief port 2 is opened above the wall of the ray machine room 7 adjacent to the control room 7. By arranging the pressure relief port 2 above the wall of the ray machine room 7, the heptachloropropane is prevented from flowing from the bottom and being below the concentration of fire extinguishing.

[0030] Preferably, the buckle 5 comprises: a fixing piece 51 fixedly connected on both sides of the window frame 3.

[0031] In a preferred embodiment, the fixing member 51 is fixedly connected to the two sides of the window frame 3, and the window shutter 4 is placed on the pressure relief port 2, and the window shutter is fixed on the window frame 3 by the fixing member 51 when covering the pressure relief port 2.

[0032] Preferably, the buckle 5 further comprises a connecting member 52 movably connected to the fixing member 51, and the lead sheet is installed on or removed from the pressure relief port 2 by rotating the connecting member 52.

[0033] In a preferred embodiment, the connecting member 52 is rotated first, and then the window frame 3 is placed on the pressure relief port 2, and then the connecting member 52 is rotated to fix the window shutter 4 on the position of the pressure relief port 2, and when the window shutter 4 needs to be removed, the connecting member 52 is rotated to remove the window shutter 4, which is convenient for taking and placing.

[0034] Preferably, the material of the window shutter 4 is lead, and the atomic number of lead (pb) is 82, the density is 11.34 g / cm³, the melting point is 327.4℃, the Brinell hardness is 4.0, the compressive strength is 154 kgf / cm², the elongation is 45%, and it has the characteristics of corrosion resistance and strong attenuation of X-ray and γ-ray, and is easy to process into a good protective material.

[0035] In some preferred embodiments, the lead sheet is selected as the window shutter 4, which not only has the effect of preventing radiation, but also can be conveniently fixed on or removed from the pressure relief port 2, and can save cost.

[0036] Preferably, the width of the window frame 3 is 5-10 cm, and the material of the window frame 3 is lead.

[0037] In some preferred embodiments, the lead plate is selected as the window frame 3, and the thickness of the lead plate is thicker than that of the lead sheet, which can further prevent radiation around the pressure relief port 2.

[0038] In the second aspect of the present application, the present application provides the application of the radiation-proof ventilation and pressure relief device in a medical diagnostic X-ray machine room, which can not only ensure the integrity of the radiation protection shielding of the machine room, but also avoid the harm to the personnel in the machine room caused by heptachloropropane in the case of not timely escape.

[0039] The application provides a radiation-proof ventilation and pressure relief device, which comprises a pressure relief opening 2 formed on one side of a wall of a radiology room 1, a window frame 3 fixed around the pressure relief opening 2, and lead plates selected as the window frame 3. Rotatable buckles 5 are arranged on both sides of the window frame 3. During daily work, the lead sheets are fixed on the pressure relief opening 2 through connecting pieces 52 of the buckles 5 to cover the pressure relief opening 2 and prevent X-ray leakage from irradiating the surrounding people. The lead sheets overlap with lead leaves 6 protruding around the lead plates when the lead sheets cover the pressure relief opening 2. The lead sheets have a certain flexibility. When the radiology room catches fire, heptachloropropane rapidly fills the entire room. The strong pressure can force the lead sheets to bend or fall, so as to achieve the purpose of pressure relief and prevent people who do not escape in time from suffocation.

[0040] The above merely describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
