Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
Embodiment one: as shown in fig. 1 to 11, an apparatus for preventing bacterial infection in an intensive care unit, comprising: the bedside table 1, the safety cover subassembly and the flexible subassembly 6, wherein bedside table 1 is used for placing article and is provided with a plurality of bin 18 promptly, and bedside table 1 has seted up and is used for article sterile disinfection chamber 11 to bedside table 1 top is provided with air purifier 2.
Therefore, in the actual use process, the articles of patients can be disinfected by arranging the disinfection cavity 11 for disinfecting the articles in the bedside table 1, and the articles of different patients do not need to be classified and numbered before going to the disinfection cabinet, so that a certain labor force is reduced.
And the position of the bed needs to be moved during actual use so as to realize better utilization of space, therefore, wheels 19 with braking plates can be arranged at the bottom of the bedside table 1, the braking plates can be moved to a place which does not obstruct the movement of the bedside table 1 during movement, and the braking plates can be moved to a place which obstructs the movement of the bedside table 1 during stopping.
As shown in fig. 1-3, the telescopic assembly 6 is used for connecting the protective cover assembly and the bedside table 1, and extending the protective cover assembly to the sickbed and covering the outer side of the patient, and placing the protective cover assembly on the upper side of the air purifier 2 in a zooming way and abutting with the air purifier 2.
As shown in fig. 4 and 6, the protection cover assembly includes a first protection cover 3 for protecting the upper body and a second protection cover 4 for protecting the lower body, and the second protection cover 4 is movably disposed in the first protection cover 3, and a foldable baffle 5 is clamped at the openings of the first protection cover 3 and the second protection cover 4, so that dust is prevented from entering.
Therefore, in the actual use process, the protective cover assembly is connected through the telescopic assembly 6, so that the protective cover assembly can be extended and retracted, and the second protective cover 4 and the protective cover assembly which are arranged in a matched and movable mode only cover a patient, so that the volume is reduced, and the occupied area is reduced.
As shown in fig. 2, 8 and 11, an air inlet 21 is formed in the top of the air purifier 2, a first connecting pipe 22 connected with a first protecting cover 3 and a second connecting pipe 23 connected with a second protecting cover 4 are respectively arranged on two sides of the air purifier 2, and a first purifying chamber 24 connected with the first protecting cover 3 and a second purifying chamber 25 connected with the second protecting cover 4 are arranged in the air purifier 2.
Meanwhile, the first purifying chamber 24 and the second purifying chamber 25 are communicated through the fan 26, so that in the actual use process, air in the protective cover assembly sequentially flows through the second connecting pipe 23, the second purifying chamber 25, the fan 26 and the first purifying chamber 24 through the first connecting pipe 22 and returns to the protective cover assembly, circulation is realized, and the air is purified cleanly through the first purifying chamber 24 and the second purifying chamber 25.
Meanwhile, a valve 27 is arranged between the second purifying chamber 25 and the fan 26, and the fan 26 is controlled to absorb air entering from the air inlet 21 or/and air coming from the second purifying chamber 25 through the valve 27, so that the condition of vacuum in the protective cover assembly is avoided.
Compared with the prior art, the air in the cover is absorbed and then purified, so that vacuum condition can occur, and the patient is influenced. The invention does not adopt the valve 27, so that the fan 26 firstly absorbs the air entering from the air inlet 21 and supplies air to the protective cover assembly and then absorbs the air coming from the second purifying chamber 25, thereby avoiding the condition of vacuum in the protective cover assembly.
As shown in fig. 9-10, the structure of the valve 27: first, the valve 27 includes a stem 271 and a valve seat 272, wherein one end of the stem 271 is positioned within the valve seat 272 and the other end of the stem 271 is coupled to an electromagnetic drive source 273.
Meanwhile, the valve seat 272 is provided with a first channel 274 and a second channel 275 respectively, the first channel 274 and the second channel 275 are vertically arranged, and the second channel 275 is provided with an inclined surface 276 in an outward inclined manner at an opening far from the electromagnetic driving source 273.
And the stem 271 is provided with a through hole 277 and the sidewall of the stem 271 is provided with a recess 278. Thus, in actual use, when the electromagnetic drive source 273 is not energized, the second channel 275 and the first channel 274 are communicated through the groove 278, thereby controlling the blower 26 to absorb air entering from the air intake 21. And when the electromagnetic driving source 273 is energized, the through hole 277 communicates with the passage one 274, thereby controlling the blower 26 to suck the air from the clean room two 25.
And the valve rod 271 is further provided with a third channel 279, and the third channel 279 is communicated with the groove 278, so that the valve rod 271 moves to the third channel 279 to be communicated with the first channel 274, and the fan 26 can be controlled to absorb the air coming from the second purifying chamber 25 and the air entering from the air inlet 21 at the same time.
Thus, in the actual use process, the valve rod 271 moves to enable the first channel 274 to be communicated with different parts, so that different communication can be realized through one valve 27, and the number of the valves 27 is reduced.
As shown in fig. 2, the control panel 12 is further included, which is disposed outside the bedside table 1, and the bottom of the protective cover assembly is provided with a first sensor, when the first sensor contacts the coverlet, information is given to the control panel 12 to turn on the blower 26, and the blower 26 absorbs air entering from the air inlet 21.
Meanwhile, a second inductor is arranged at the outlet of the first connecting pipe 22, and when the second inductor senses that the air quantity is a certain value, information is given to the control panel 12 so as to control the fan 26 to absorb air from the second purifying room 25, so that circulation is realized.
The constant value here means that the air volume increases immediately after no air circulation is started and after the air circulation is completed in the third channel 279, and thus the air volume changes, and information can be given to the control panel 12 by the change of the air volume. And, corresponding to channel three 279, whether channel three 279 is in communication or via 277 is in communication may be accomplished by varying the magnitude of the current.
Therefore, in the actual use process, through the arrangement of the first inductor, the air can be purified after being covered, the isolation effect is guaranteed, and meanwhile, through the arrangement of the second inductor, air suction can be realized while the air is conveyed by the fan 26, and the condition that the air pressure in the protective cover assembly is overlarge is avoided.
As shown in fig. 4, the inner wall of the first protection cover 3 is provided with an air outlet member 33 which is communicated with the first connection pipe 22 and provided with an air outlet hole, the inner wall of the second protection cover 4 is provided with an air suction member 42 which is communicated with the second connection pipe 23 and provided with an air suction hole 421, and the height of the air outlet member 33 is lower than that of the air suction member 42.
Therefore, in the actual use process, the height of the air outlet piece 33 is lower than that of the air suction piece 42, so that the upper air can be sucked away through the air suction piece 42, the lower air is pushed to the upper air through the air outlet of the air outlet piece 33 and then sucked away, and the air in the protective cover assembly is ensured to be purified completely.
