Description
Technical Field
[0001] The utility model relates to the technical field of gas terminal boxes, in particular to an operating room gas terminal box which is easy to clean. Background Art
[0002] The medical gas terminal box can be called a medical gas terminal board. Medical gas refers to the gas used in the medical process. The medical gas terminals mainly include: oxygen terminal, nitrogen terminal and carbon dioxide gas terminal, etc. The gas in the medical gas terminal box is transported through pipelines and has good safety.
[0003] However, during the use of the medical equipment belts currently on the market, since the joint components on the medical equipment belts are exposed to the outside world, the joint components are easily contaminated with bacteria after being used for a period of time, so they need to be wiped manually with medical alcohol to achieve disinfection and sterilization, which increases the burden of manual labor. In order to reduce the burden of manual labor when disinfecting its gas joints, the utility model with technical publication number: CN219510622U discloses a transportation safety protection type medical gas terminal box (hereinafter referred to as: prior art 1), including a terminal box body, and a groove opened on the outside of the terminal box body, and a gas terminal body arranged in the groove, the outside of the terminal box body is provided with two groups of slide grooves, the slide groove is provided with a first metal block, the slide groove is also provided with a second metal block, the slide groove is slidably connected with a slider, the outside of the slider is provided with a connecting rod, the outside of the terminal box body is provided with a protective block fixed to the connecting rod, and the side of the protective block close to the terminal box body is provided with a recessed groove, and the recessed groove is provided with an ultraviolet sterilization component.
[0004] Although the prior art 1 performs ultraviolet sterilization on the medical gas terminal box by setting up an ultraviolet sterilization component; however, the connector components exposed to the outside are not only easily contaminated by bacteria but also extremely easy to accumulate dirt. Impurities in the outside air are easily attached to the surface and the inside of the connector components, which causes patients to inhale these impurities when using medical gas. At the same time, if the dirt on the connector components is not cleaned for a long time, it will produce odor, affecting the patient experience. Utility Model Content
[0005] The purpose of the utility model is to provide an operating room gas terminal box which is easy to clean. In actual use, it can solve the problem in the prior art that impurities in the outside air are easily attached to the surface of the joint component and the inside of the joint, which causes the patient to inhale these impurities when using medical gas. At the same time, the dirt on the joint component will produce odor if it is not cleaned for a long time.
[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0007] An operating room gas terminal box that is easy to clean, comprising a terminal box body and a gas source device arranged in the terminal box body, wherein the gas outlet end of the gas source device is connected to a gas terminal, the gas terminal comprises an inlet pipe, a valve and an outlet pipe connected in sequence, and further comprises a sleeve, a dust cover and a joint assembly installed on the outlet pipe, wherein the sleeve is installed on the terminal box body;
[0008] The joint assembly includes a first joint and a second joint, the first joint is arranged in the sleeve and connected to the air outlet pipe, the first joint is provided with a mounting groove, a limit block is installed in the mounting groove; a first spring is arranged in the mounting groove, a steel ball is arranged between the first spring and the limit block, the second joint is threadedly connected to the limit block, and the second joint is provided with a slot for cooperating with the steel ball to realize air flow interruption;
[0009] The sleeve is provided with a first buckle, and the dust cover is provided with a second buckle for matching with the sleeve; one end of the dust cover located in the sleeve is connected with a sealing part for sealing the first joint.
[0010] Preferably, an annular groove is provided on the sleeve, a limiting protrusion corresponding to the annular groove is provided on the dust cover, and a second spring is installed in the annular groove.
[0011] Preferably, a pressure gauge is installed on the air outlet pipe.
[0012] Preferably, four gas terminals are arranged in the box, and the four gas terminals are used to be connected to four different gas source devices.
[0013] Preferably, the dust cover is a dust cover with a stepped structure, and the stepped surface formed by the side wall of the dust cover is used to contact the inner wall of the sleeve.
[0014] Preferably, the sealing portion is detachably connected to the dust cover.
[0015] Preferably, the sealing portion is detachably connected to the dust cover.
[0016] Preferably, an observation window is provided on the terminal box.
[0017] Compared with the prior art, the utility model has the following beneficial effects:
[0018] In the utility model, the second joint is used to connect with the gas-using equipment, and the first buckle arranged on the sleeve is an L-shaped structure; when the first joint is not connected with the second joint, the dust cover is installed at the open end of the sleeve and then the dust cover is rotated, so that the second buckle arranged on the dust cover enters into the limiting area formed in the first buckle arranged in the L-shaped structure after the dust cover rotates, and after the first buckle limits the second buckle, the dust cover is connected to the sleeve; after the dust cover is connected to the sleeve, the dust cover plays a role of sealing and dustproofing for the first joint arranged in the sleeve, thereby preventing impurities in the outside air from adhering to the surface of the joint assembly.
[0019] When it is necessary to connect the first joint with the second joint, the dust cover is rotated to release the limit of the first buckle on the second buckle and then the dust cover is removed; the air outlet end of the second joint is rotated to be connected to the useful air pipe, the useful air pipe is used to connect with the air-using equipment, and the steel ball is connected to the installation groove through the first spring; after the second joint is inserted into the first joint, the second joint is rotated to make the second joint pass through the first threaded hole set on the limit block and then abut against the steel ball, and the port of the second joint contacts with the steel column and continues to press the steel ball. Under the extrusion of the second joint, the first spring is deformed by force, and the steel ball is deformed with When the first spring moves to a point where it is no longer in contact with the limit block, the valve installed on the air outlet pipe is opened; the airflow in the air outlet pipe enters the installation groove through the gap of the first spring, and then enters the air pipe connected to the air outlet end of the second joint through the slot provided on the second joint and is used to supply air to the air-using equipment, which is the ventilation state; the second joint is rotated to move the second joint toward the end away from the steel ball, and at this time, the steel ball moves toward the direction of the limit block under the action of the first spring until it abuts against the limit block, and the steel ball abutting against the limit block closes the airflow;
[0020] In the process of connecting the first joint and the second joint to form a passage, some dust and impurities will adhere to the surface of the first joint that is exposed to the outside air and not covered by the dust cover. However, because the steel ball provided in the utility model contacts with the limiter, it can block the airflow while preventing dust and impurities from accumulating inside the joint to form dirt. Therefore, the operator only needs to clean the dust and impurities attached to the surface of the first joint to avoid the dirt accumulated on the first joint from producing odor and affecting the patient experience.
