Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

In some embodiments, a hospital bed unit ozone sterilizer, as shown in fig. 1 and 4, is used to convert air source 400 oxygen into ozone, thereby sterilizing mattress 300. The air source 400 may be a normal atmosphere or may be air that has been simply treated and stored in a device, such as air that has been dried and dehumidified in a relatively humid environment. The bed unit sterilizer comprises a housing 13 shown in fig. 1, a joint area 5 embedded on the top surface of the housing 13, an ozone generator group 3 and an air pump group 9 which are jointly positioned in the housing 13. The ozone generator group 3 includes a pad ozone generator 32; the air pump unit 9 includes a cushion air pump 92; the joint region 5 includes a pad joint 53.

As shown in FIGS. 5-7, mattress 300 includes an air inflation interface 310, a sealing cover 320, a fitted sheet 330, and padding 340; the fitted cover 330 is made of tightly woven canvas or other materials with air impermeability; the filler 340 may be conventional palm fiber or other material of moderate hardness for easy placement. Filler 340 is wrapped inside fitted sheet 330, and air inflation inlet 310 has a hollow tubular structure, and one end is embedded in fitted sheet 330, and the other end is detachably fastened to sealing cover 320. The inflation interface 310 and the sealing cover 320 can be detachably connected by a threaded connection, and the sealing cover 320 can be plugged into the opening of the inflation interface 310 by an interference fit manner in a manner similar to a thermos bottle plug; meanwhile, in order to ensure the tightness between the inflation port 310 and the sealing cover 320, a sealing ring or other common sealing designs may be disposed around the outer circumferential wall of the inflation port 310 or the inner circumferential wall of the sealing cover 320, which will not be described in detail herein.

As shown in fig. 3, 5 and 6, when it is required to inject ozone into the mattress 300, the sealing cover 320 is separated from the air inlet 310, and the pad connector 53 is connected to the air inlet 310 through an external connection pipe. Thus, the cushion air pump 92, the cushion ozone generator 32, the cushion connector 53 and the inflation connector 310 are connected in series in sequence to form a cushion air transmission pipeline communicated with each other inside; at this time, the air pump 92 for the mat and the ozone generator 32 for the mat are started, so that the oxygen in the air source 400 can be sucked and transmitted to the ozone generator 32 for the mat to be converted into ozone, and then the ozone is continuously transmitted along with the gas transmission pipeline for the mat and enters the bed cover 330 through the air inflation connector 310, and further permeates into the filler 340 and is sterilized and disinfected. The fitted sheet 330 has air impermeability, so that the ozone is sealed by the fitted sheet 330; after a certain time, the disinfection effect of ozone reaches the best, then the air pump 92 for the pad and the ozone generator 32 for the pad are stopped, the connection between the connector 53 for the pad and the air inflation connector 310 is disconnected, then the sealing cover 320 and the air inflation connector 310 are sealed and fastened again, at the moment, the ozone is retained in the bed cover 330, and the mutual permeation and sufficient contact are continuously carried out on the filler 340, so that the sterilization and disinfection are continuously carried out; meanwhile, due to the chemical instability of ozone, the ozone is slowly decomposed and reduced into oxygen in the process of continuing sterilization and disinfection. It should be noted here that, because the volume of the mattress is smaller than that of other bed unit products such as bedding, the amount of ozone introduced is smaller, and by utilizing the characteristic, ozone is introduced into the filler 340 and then is automatically decomposed in the filler 340, so that the sterilization time of the ozone can be effectively prolonged, the sterilization effect can be enhanced, and other devices for decomposing the ozone are not required to be loaded, thereby achieving two purposes; meanwhile, due to long-time sealing, a very small amount of ozone can also permeate from the fitted sheet 330, so that the outer surface of the fitted sheet 330 is automatically decomposed after being sterilized and disinfected, and air pollution is effectively avoided.

More preferably, in order to make the ozone introduced into mattress 300 more uniform, air inlet 310 is preferably provided in two as shown in fig. 5 and fitted into both ends of the side surface of fitted sheet 330; the pad connectors 53 also amount to two and are in parallel relationship with each other; the mat connectors 53 are each piped at one end to the mat ozone generator 32 and at the other end to a gas fill port 310. Of course, more air-filling ports 310 uniformly distributed on fitted sheet 330 and the fitting joint 53 for mat can be added for uniform ozone introduction, and will not be described in detail here.

In conclusion, the device of the present application enables ozone to be blended into the filler 340 and remain in the fitted sheet 330 by designing the dedicated gas transmission pipeline and configuring the mattress 300, so that the ozone has sufficient time to contact and mutually permeate the filler 340, thereby effectively prolonging the sterilization time and the sterilization effect; meanwhile, the ozone can be automatically decomposed along with time without loading a special ozone decomposition device; and because of long-time sealing, a very small amount of ozone can also permeate from the fitted sheet 330, and the environment can not be polluted while the outer surface of the fitted sheet 330 is sterilized and disinfected. Therefore, the device realizes the sterilization and disinfection process of the mattress 330 from inside to outside by using a simple and optimized structure and method, and has strong popularization value.

In some embodiments, the present apparatus can effectively sterilize and disinfect the inside of the mattress 300, and can also sterilize and disinfect the bed unit 200, such as bedding, pillow, etc. The apparatus of the present application, as shown in FIGS. 1, 4 and 5, is further provided with a valve block 8 and a resolver 4 inside the casing 13, and a sterilizing cover 100 outside the casing 13.

The valve group 8 comprises a first valve 81, a second valve 82 and a third valve 83 connected in parallel with the second valve 82; the ozone generator group 3 further comprises a bed ozone generator 31; the connector zone 5 further comprises a first bed connector 51 and a second bed connector 52; the air pump unit 9 further includes a bed air pump 91.

As shown in FIG. 5, the first valve 81, the bed air pump 91, the bed ozone generator 31, the first bed joint 51 and the sterilizing cover 100 are connected in sequence by piping to form a bed gas transfer line. The oxygen from the air source 400 is converted to ozone and passed into the sterilization enclosure 100, wherein the first valve 81 is connected to the air source 400 and is used to control the opening and closing of the gas delivery line for the bed, the air pump 91 is used to power the gas delivery, and the ozone generator 31 is used to convert the oxygen to ozone, the operation of which will be described in detail in the following embodiments. Meanwhile, since the bed unit 200 has a larger size than the mattress 300 and requires more ozone to be introduced, as shown in fig. 4 and 5, the bed ozone generators 31 are two in total and are connected in parallel with each other, and one end of each bed ozone generator is connected to the bed air pump 91 and the other end of each bed ozone generator is connected to the first bed connector 51, so that the bed air pump 91 can selectively pump more oxygen and convert more ozone, and the ozone is collected into the first bed connector 51 together via the two bed ozone generators 31 and finally transferred to the sterilizing cover 100.

The bed air pump 91, the bed ozone generator 31, the first bed connector 51, the disinfection cover 100, the second bed connector 52 and the third valve 83 are connected end to end in sequence to form a closed loop disinfection circulation loop with communicated inner parts. When sufficient ozone is introduced into the sterilization enclosure 100, the first valve 81 can be closed to cut off the gas transmission pipeline for the bed, and the third valve 83 can be opened to open the sterilization circulation loop for the bed, so that the ozone forms a circulation gas flow to perform a blowing type dynamic sterilization on the bed unit 200, and the specific operation manner is described in detail in the following embodiments.

The disinfection cover 100, the second bed connector 52, the second valve 82, the resolver 4 and the bed air pump 91 are sequentially connected end to form a bed resolving pipeline communicated with each other. When the disinfection time of the bed unit 200 is met, the third valve 83 is closed to cut off the disinfection circulation loop for the bed, and the second valve 82 is opened to open the desorption pipeline for the bed, so that the ozone is adsorbed to the desorption device 4 and decomposed into oxygen under the action of the power generated by the air pump 91 for the bed, and finally, the discharge is realized. In order to accelerate the decomposition rate, the resolver 4 is added with a catalyst such as active enzyme, and the specific operation mode is described in detail in the following examples.

The mattress 300 and the bed unit 200 can be sterilized at the same time, the bed unit 200 is stacked on the mattress 300 during sterilization, the lower surface of the bed unit 200 is contacted with the upper surface of the mattress 300, the upper surface of the mattress 300 is a surface which is easy to be stained by a patient, and then the sterilization cover 100 covers and seals the bed unit 200. In this way, when the mattress 300 and the bed unit 200 are sterilized at the same time, ozone for sterilizing the bed unit 200 can be permeated to the upper surface of the mattress 300 in a small amount, and ozone for sterilizing the inside of the mattress 300 can be permeated to the upper surface of the mattress 300 in a small amount. In conclusion, the sterilization and disinfection method achieves targeted double sterilization on the upper surface of the mattress 300, namely the position where the mattress 300 is most seriously polluted.
