Description

Technical Field

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

[0002] 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 determine 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 equipment have certain radiation hazards to the surrounding people, the machine room must take corresponding shielding measures. In addition, because the price of the above equipment is relatively expensive, ranging from hundreds of thousands to tens of millions, the fire safety of the machine room often uses heptachloropropane as a fire extinguishing agent. Heptachloropropane has a good fire extinguishing effect and strong ability to prevent re-ignition. It is colorless and odorless, low pollution, low residue, and dust-free. It is convenient to take care of the fire items after the disaster, and is more suitable for fire safety in important places such as libraries, archives, and important machine rooms.

[0003] With the vigorous development of fire fighting technology, fire fighting facilities are becoming more and more coordinated. Once the fire alarm is triggered in the machine room, the heptachloropropane fire extinguishing agent will spontaneously spray out and quickly fill the entire fire fighting area. In the case of a medical diagnostic X-ray machine room, if the personnel in the machine room do not escape in time when the fire alarm is triggered, the heptachloropropane under high pressure may cause suffocation and death of the personnel in the machine room.

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. In the description of the present invention, it should be noted that the term "or" is usually used in the sense of including "and / or", unless the content clearly indicates otherwise.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a magnetic connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the description of the present invention, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. In the description of the present invention, the meaning of "multiple" is at least two, such as two, three or more, etc., unless otherwise clearly and specifically limited.

[0023] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[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 determine 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 equipment have certain radiation hazards to the surrounding people, the machine room must take corresponding shielding measures. In addition, because the price of the above equipment is relatively expensive, ranging from hundreds of thousands to tens of millions, the fire safety of the machine room often uses heptachloropropane as a fire extinguishing agent. With the vigorous development of fire fighting technology, fire fighting facilities are becoming more and more coordinated. Once the fire alarm is triggered in the machine room, the heptachloropropane fire extinguishing agent will spontaneously spray out and quickly fill the entire fire extinguishing area. In the case of a fire alarm in the medical diagnostic X-ray machine room, if the personnel in the machine room do not escape in time, the heptachloropropane under high pressure may cause the personnel in the machine room to suffocate and die.

[0025] The present invention provides a radiation protection ventilation and pressure relief device. Figure 1 FIG. 1 is a schematic structural diagram of a radiation protection pressure relief device provided by an embodiment of the present invention; Figure 2 The figure shows a schematic diagram of a structure in which a pressure relief port provided by an embodiment of the present invention is not covered with lead sheet; Figure 3FIG. 1 is a schematic diagram of a structure of a pressure relief port covered with lead sheet provided in an embodiment of the present invention. Figure 1-3 As shown, the radiation protection ventilation and pressure relief device includes: a radiation room 1; a control room 7, which is located on one side of the radiation room 1; a pressure relief port 2, which is opened on the wall of the radiation room 1 on one side adjacent to the control room 7; a window frame 3, which is fixedly connected around the pressure relief port 2; a window baffle 4; and a buckle 5, which is installed on both sides of the window frame 3 and is used to fix the window baffle 4 on the window frame 3.

[0026] 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 patients. The X-rays emitted by the equipment pose certain radiation hazards to the surrounding people, so its radiation room 1 must take corresponding shielding measures. When examining human tissues, the medical diagnostic X-ray equipment is controlled by the control room to perform corresponding inspections. When an emergency such as a fire occurs, the fire alarm will be automatically triggered in the room, and the heptachloropropane fire extinguishing agent will spontaneously spray out and quickly fill the entire fire extinguishing area. In the case where the fire alarm is triggered in the medical diagnostic X-ray room, in order to prevent the X-rays emitted by the equipment from causing certain radiation hazards to the surrounding people, a closed space is formed around the room. If the personnel in the room fail to escape in time in the closed space, the heptachloropropane under high pressure may cause suffocation and death to the personnel in the room. By opening a pressure relief vent 2 on the wall of the ray room 1 on the side adjacent to the control room 7 and installing a window baffle 4 on the pressure relief vent 2, when an emergency such as a fire occurs, the pressure relief vent 2 can allow air to circulate inside and outside, and the personnel in the room will not be suffocated or killed because of being in the closed space.

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

[0028] Preferably, the window baffle 4 is covered on the lead sheet 4. The window baffle 4 is used to protect against radiation hazards. Covering the window baffle 4 on the lead sheet 6 can prevent a gap from being generated between the lead sheet 6 and the window baffle 4, thereby better protecting against radiation.

[0029] Preferably, the pressure relief port 2 is opened above the wall of the radiation room 7 adjacent to the control room 7. The pressure relief port 2 is arranged above the wall of the radiation room 7 to prevent heptachloropropane from escaping from the bottom and falling below the concentration of fire extinguishing.

[0030] Preferably, the buckle 5 includes: a fixing member 51 , and the fixing member 51 is fixedly connected to two sides of the window frame 3 .

[0031] In a preferred embodiment, the fixing member 51 is fixedly connected to both sides of the window frame 3 to facilitate placing the window baffle 4 on the pressure relief port 2. When the pressure relief port 2 is covered, the window baffle is fixed to the window frame 3 by the fixing member 51.

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

[0033] In a preferred embodiment, the connecting member 52 is first rotated to place the window frame 3 on the pressure relief port 2, and then the connecting member 52 is rotated to fix the window baffle 4 at the position of the pressure relief port 2. When the window baffle 4 needs to be removed, the window baffle can be removed by rotating the connecting member 52, which is convenient for taking and placing.

[0034] Preferably, the window baffle 4 is made of lead, the atomic number of lead (Pb) is 82, and the density is 11.34 g / cm 3 , melting point is 327.4℃, Brinell hardness is 4.0, compressive strength is 154kgf / cm 2 , elongation is 45%, it is corrosion-resistant and has strong attenuation characteristics of X-rays and gamma rays. It is easy to process and shape, and is a good protective material.

[0035] In some preferred embodiments, lead sheet is selected as the window baffle 4. The lead sheet not only has the function of radiation protection, but also can be conveniently fixed on or removed from the pressure relief port 2, and can save costs.

[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, a lead plate is selected as the window frame 3 . The thickness of the lead plate is thicker than that of the lead plate, which can further provide radiation protection around the pressure relief port 2 .

[0038] In the second aspect of the present invention, the present invention provides an application of a radiation-proof ventilation and pressure relief device in a medical diagnostic X-ray machine room. The application of the radiation-proof ventilation and pressure relief device in a medical diagnostic X-ray machine room can not only ensure the integrity of the radiation protection shielding of the machine room, but also prevent heptachloropropane from causing harm to the personnel in the machine room if the personnel in the machine room fail to escape in time.

[0039] The present invention provides a radiation-proof ventilation and pressure relief device, which opens a pressure relief port 2 on a wall on one side of a radiation room 1, fixes a window frame 3 around the pressure relief port 2, selects a lead plate as the window frame 3, and arranges a rotatable buckle 5 structure on both sides of the window frame 3. During daily work, the lead sheet is fixed on the pressure relief port 2 through a connector 52 on the buckle 5 to cover the pressure relief port 2, thereby preventing X-ray leakage from irradiating surrounding personnel. When the lead sheet covers the pressure relief port 2, it overlaps with lead sheets 6 protruding around the lead plate. The lead sheet has a certain flexibility. When the room is on fire, heptachloropropane quickly fills the entire room, and the strong pressure can force the lead sheet to bend or fall, thereby achieving the purpose of pressure relief and preventing people who fail to escape in time from suffocating.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
