Detailed Description

The utility model belongs to the field of medical equipment, concretely relates to gaseous separation device.

The gas blocking device comprises a blowing mechanism, the blowing mechanism is annularly wrapped on the part to be blocked of the medical equipment, and purified air with pressure is introduced into the blowing mechanism. The air blowing mechanism comprises an air blowing pipe, and the air blowing pipe is connected with an air purification device through an air compressor.

During the period of high incidence of new coronary pneumonia, the medical emergency ambulance needs to stay at any time and quickly convey a patient to a designated medical point for treatment, equipment used by an infected person, such as an oxygen tube and other facilities, can have a large amount of germs, the emergency equipment is often urgent when in use and must be immediately put into a use state, if the disinfection is not thorough, the infection risk exists, the perfect and thorough disinfection wastes time, and the optimal time for emergency treatment is delayed. Even if the equipment on the emergency ambulance is not used by the infected person, there is a risk that viruses will attach to the equipment, and if the next patient is urgently needed to be rescued, the next patient may be at risk of infection.

As shown in fig. 1, the blocking device is an embodiment used on a medical emergency ambulance, and the blocking device includes a blocking sleeve 1, the blocking sleeve 1 is sleeved on a pipeline to be blocked and is slidably connected with the pipeline to be blocked, the blocking sleeve 1 includes a sleeve outer layer 3 and a sleeve inner layer 4, a cavity for containing purified air is formed between the sleeve outer layer 3 and the sleeve inner layer 4, the sleeve inner layer 4 is provided with a plurality of through holes 5, and the through holes 5 correspond to positions to be blocked on the pipeline to be blocked; be provided with on the outer 3 of sleeve pipe and insert mouth 7, insert mouth 7 and be connected with the air purification device on the emergency tender through the air compressor machine. The blocking sleeve 1 is sleeved on the part to be blocked, so that purified air is always kept in a blowing state, and purified air pressure covers the part to be blocked, so that an isolation area is formed to play a role in protection, and the part to be used is isolated from the external atmosphere; the purified air containing the sterilizing component can be obtained by connecting a sterilizing gas generating device in series between an air purifying device and an air compressor, and the device is the prior art, so that the description is omitted; the pressure of the air compressor can be adjusted, and the blown air pressure is adjusted; when not in use, the air compressor can be stopped only by closing the air compressor.

It can be understood that the air compressor makes the purified air generate pressure to blow and cover the part to be blocked, and the pathogenic bacteria in the air can not be attached to the part to be blocked through the action of the pressure and the airflow; the sterilization gas can be continuously introduced into the blocking sleeve 1 without using an air compressor, and the pipeline to be used is sterilized, so that the pipeline to be used is always in the sterilization atmosphere.

The sleeve inner layer 4 is fixedly connected with the elastic ring 9, and the elastic ring 9 is sleeved on the pipeline to be blocked. The elasticity of the elastic ring 9 can ensure that the blocking sleeve 1 can be fixed at a position and cannot slide along the pipeline, the pipeline cannot be pressed tightly by the elasticity of the blocking sleeve, and the condition that gas or liquid in the pipeline cannot flow cannot occur.

The separation sleeve 1 is fixedly connected with the telescopic sleeve 6, the other end of the telescopic sleeve 6 is fixedly connected with the connecting sleeve 11, the telescopic sleeve 6 and the connecting sleeve 11 both comprise an outer layer and an inner layer, and cavities formed between the outer layer and the inner layer of the telescopic sleeve 6 and the connecting sleeve 11 are communicated with each other and communicated with a cavity formed by the sleeve outer layer 3 and the sleeve inner layer 4; after the telescopic tube 6 is compressed, the outer layer and the inner layer of the telescopic tube 6 are contacted, the separated and purified air passes through, the inner layer of the connecting sleeve 11 is fixedly connected with the elastic ring 9, and the elastic ring 9 is sleeved on the pipeline to be separated. When the barrier sleeve 1 is used, the telescopic sleeve 6 is in a stretching state, and purified air can pass between the outer layer and the inner layer of the telescopic sleeve 6; when the blocking sleeve 1 is not needed, the blocking sleeve 1 can be pushed to the left (in the direction shown in fig. 1), and at this time, the telescopic sleeve 6 is folded together, so that the passage through which the purified air passes is closed, and no purified air is blown out of the through hole 5. Because the air compressor will be equipped with the gas holder, consequently when telescopic tube 6 is folded together, can need not close the air compressor machine, the air compressor machine feels self pressure and rises the back, can automatic deceleration for the pressure gas storage that produces is reserved in the gas holder, and the size of gas holder can be selected according to actual need.

The pipeline to be blocked is an oxygen pipe 10, four through holes 5 are formed in the sleeve inner layer 4, the two through holes 5 in the middle correspond to the two air outlets 2 in the oxygen pipe 10 respectively, and the diameter of each through hole 5 is larger than that of each air outlet 2. After the purified air is blown out, the purified air can completely cover the air outlet 2 of the oxygen tube 10 to block the surrounding environment. The sleeve pipe inlayer 4 of separation sleeve pipe 1 also can be made by soft materials, and when the air pressure of purification insufflates into cavity 8, the expansion of sleeve pipe inlayer 4 pressurized, at this moment, gas outlet 2 stretches into in the through-hole 5 to better keeping apart.

The specific working mode is as follows: before the medical emergency ambulance is used, medical personnel will disinfect the facilities to be used in the emergency ambulance, cover separation sleeve pipe 1 on oxygen hose 10 after disinfecting for open the air compressor machine, make the air-purifying blow and cover on gas outlet 2, separate gas outlet 2 and surrounding air atmosphere mutually.

If the medical emergency ambulance is only used for carrying infected patients, the infected viruses can not be attached to the air outlet 2 due to the blocking effect of purified air, and the quick use of the next patient can not be influenced.

If the infected person needs to use the oxygen hose 10, the medical staff only needs to push the blocking sleeve 1 leftwards to fold the telescopic sleeve 6, and the purified air in the blocking cavity 8 is continuously blown out, so that the infected person can directly use the oxygen hose 10; after the infected person finishes using the oxygen tube 10, the medical staff directly changes the oxygen tube 10 or performs disinfection and sterilization again, and then the blocking sleeve 1 is sleeved at the air outlet 2, so that the oxygen tube 10 is in a standby state.

The above embodiments are preferred embodiments, it should be noted that the above preferred embodiments should not be considered as limitations of the present invention, and the scope of the present invention should be limited by the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and enhancements can be made without departing from the spirit and scope of the invention, and such modifications and enhancements are intended to be within the scope of the invention.
