As shown in fig. 7 and 8, when medical staff prevents the blood collection tube 80 from being inserted into the tube sleeve 30 and turns over the cap 40 to cover the placement hole 201, the cap 40 presses the blood collection tube 80 downwards to press the first elastic membrane 301 downwards so as to reduce the closed space below the first elastic membrane 301, gas in the closed space is introduced into the inner cavity of the slideway 501 far away from the cap 40 through the first gas tube 509 to raise the gas pressure in the inner cavity of the slideway 501, at this time, the upper end of the gas release channel 506 is blocked by the lower part of the convex gas release rod 507, the first one-way valve is closed, gas in the slideway 501 cannot be discharged outwards by the gas release channel 505 and the first one-way valve, under high pressure, the slider 502 moves towards the direction close to the cap 40 against the elastic force of the second spring 503 so that one end of the slider 502 close to the cap 40 extends out of the slideway 501, when the lower edge of the cap 40 presses down the inclined surface of the sliding block 502, the sliding block 502 can be temporarily retracted into the slide 501 and the first elastic film 301 is expanded and embedded into a gap between the outer wall of the blood collection tube 80 and the inner wall of the tube sleeve 30, when the cap 40 is continuously turned over to align the jack 401 on the cap 40 with the slide 501, the sliding block 502 is inserted into the jack 401 under the pushing of high-pressure gas, at this time, the cap 40 cannot be turned over and opened, the situation that medical staff mistakenly opens the cap 40 to exchange heat with an external high-temperature field again through the placement hole 201 is prevented, the rate of temperature drop of the inner cavity of the outer box 10 is further reduced, and meanwhile, the automatic locking of the cap 40 can prevent the blood collection tube 80 from falling out of the tube sleeve 30 when the outer box 10 is carelessly poured down to enable the box cover 101 to be opened, so that the blood collection tube 80 is effectively protected.
When the blood collection tube 80 in the tube sleeve 30 needs to be taken out, the upper end of the convex exhaust rod 507 is pressed downwards, so that the convex exhaust rod 507 moves downwards, the lower part of the convex exhaust rod 507 is staggered with the upper end of the air release channel 506, at this time, the inner cavity of the slide way 501 is communicated with the outer space of the seat body 50 through the air release channel 506 and the air release channel 505, the slide block 502 moves away from the cap 40 under the elasticity of the second spring 503, so that the slide block 502 leaves the jack 401, at this time, the cap 40 can be opened, when the cap 40 is opened, the blood collection tube 80 moves upwards under the elasticity of the first spring 302, the blood collection tube 80 is conveniently taken out, at the same time, the air pressure of the inner cavity of the slide way 501 is reduced, at this time, the first one-way valve is opened, and the outer air of the seat body 50 enters the slide way 501 and then enters the closed space through the first air tube 509.
Therefore, after the blood collection tube 80 is placed in the tube sleeve 30, the medical staff can not open the cap 40 without pressing the convex exhaust rod 507, and can only open the cap 40 after pressing the convex exhaust rod 507, when the medical staff can not directly open the cap 40, the staff can understand that the blood collection tube 80 is placed in the tube sleeve 30, and can voluntarily find the next cap 40 which can be directly opened, thereby avoiding the repeated contact of the inner cavity of the tube sleeve 30 with an external high-temperature field, and being beneficial to prolonging the blood sample preservation time.
When the outer box 10 is normally transported or placed without collision, falling and other unexpected situations, the annular elastic air bag 303 is in a contracted state, a certain distance is reserved between the outer wall of the blood collection tube 80 and the outer wall of the air bag, the blood collection tube 80 is convenient to take and place, and meanwhile, the gas in the pipe sleeve 30 can flow up and down in a convection manner, so that the temperature of the blood collection tube 80 is uniform. Referring to fig. 7, when the situation of falling, dumping, collision, etc. occurs, the weight 702 in at least one of the air cylinders 701 moves under the gravity or inertia force to press the fourth spring 703 in the air cylinder 701 to move towards the closed end of the air cylinder 701, so that the air in the air cylinder 701 is pressed into the air flow channel 601 in the connecting plate 60 through the second air pipe 704 and then enters the annular elastic air bags 303 in each tube sleeve 30, so that the annular elastic air bags 303 expand to wrap the blood collection tube 80 to prevent the blood collection tube 80 from shaking and elastically buffer the blood collection tube 80, further prevent the blood collection tube 80 from being broken, the connecting plate 60 strengthens the connection strength between the tube sleeve 30 and the heat insulation plate 20, and meanwhile, the connecting plate 60 connects the tube sleeves 30 together into a whole, thereby improving the stability of the tube sleeve 30.
When the processes of collision, dumping and the like are finished, after the outer box 10 is righted, the weight 702 moves away from the closed end again under the elasticity of the fourth spring 703, and the air in each annular elastic air bag 303 flows back into the air cylinder 701 to enable the annular elastic air bag 303 to shrink away from the outer wall of the exploitation blood vessel 80, so that the exploitation blood vessel 80 and the air convection in the pipe sleeve 30 are conveniently taken out.
The foregoing is merely exemplary of the present invention, and specific structures and features that are well known in the art are not described in detail herein. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present invention, and these should also be considered as the scope of the present invention, which does not affect the effect of the implementation of the present invention and the utility of the patent.
