图1为本发明上顶面的结构示意图。FIG. 1 is a schematic structural diagram of an upper top surface of the present invention.
图2为本发明下底面的结构示意图。FIG. 2 is a schematic structural diagram of the lower bottom surface of the present invention.
如图1和图2所示，一种带有气液隔离陷阱的试剂盒，其包括盒体1、设置在盒体1侧部的进气口2、出液口3以及设置在盒体1上的储液槽4；所述储液槽4的一端通过细长流道与进气口2连通，所述储液槽4的另一端连通有出液口3，所述储液槽4与细长流道之间设置有气液隔离陷阱。As shown in FIG. 1 and FIG. 2 , a kit with a gas-liquid isolation trap includes a box body 1 , an air inlet 2 arranged on the side of the box body 1 , a liquid outlet 3 and a box body 1 . One end of the liquid storage tank 4 is connected with the air inlet 2 through the elongated flow channel, the other end of the liquid storage tank 4 is connected with the liquid outlet 3, and the liquid storage tank 4 is connected with Gas-liquid isolation traps are arranged between the elongated flow channels.
所述细长流道包括设置在盒体1下底面的第一流道5和第四流道6以及设置在盒体1上顶面的第二流道7和第三流道8，所述第一流道5、第二流道7、第三流道8、第四流道6依次连通。所述第一流道5、第二流道7和第三流道8均为回折形流道，具体可采用首尾相连的S形。气体经细长流道后，气体经反复变向流动，可延长气体到达储液槽的时间同时保证储液槽的压力均匀稳定，从而使得出液稳定，避免进气口输入气体的压力不稳造成的出液流量不稳定的问题。 The elongated flow channel includes a first flow channel 5 and a fourth flow channel 6 arranged on the lower bottom surface of the box body 1 and a second flow channel 7 and a third flow channel 8 arranged on the upper surface of the box body 1. The first flow channel 5 , the second flow channel 7 , the third flow channel 8 and the fourth flow channel 6 are connected in sequence. The first flow channel 5 , the second flow channel 7 and the third flow channel 8 are all back-folded flow channels, and specifically, an S-shape connected end to end may be adopted. After the gas passes through the slender flow channel, the gas changes its direction and flows repeatedly, which can prolong the time for the gas to reach the liquid storage tank and ensure that the pressure of the liquid storage tank is uniform and stable, so as to stabilize the liquid output and avoid the unstable pressure of the input gas at the air inlet. The problem of unstable liquid flow caused.
所述气液隔离陷阱包括设置在第三流道8与第四流道6之间的第一陷阱槽9以及设置在第四流道6与储液槽4之间的第二陷阱槽10，所述第一陷阱槽9内设置有第一气柱11，所述第二陷阱槽10内设置有第二气柱12，所述第三流道8通过第一气柱11连通第一陷阱槽9，所述第四流道6通过第二气柱12连通第二陷阱槽10。一旦储液槽内的试剂倒流回细长流道，首先会通过第四流道灌入第二陷阱槽内，此时第二气柱高于第二陷阱槽的底面，只有第二陷阱槽内的液面到达一定高度后才会到达气柱的顶部开口，进而继续倒流入第三流道，第一陷阱槽与第三流道连通，如前所述，液面需要超过第一气柱才会继续向前发生倒流，因此，气液隔离陷阱可避免液体倒流回进气口。The gas-liquid isolation trap includes a first trap groove 9 arranged between the third flow channel 8 and the fourth flow channel 6 and a second trap slot 10 arranged between the fourth flow channel 6 and the liquid storage tank 4, A first air column 11 is arranged in the first trap slot 9 , a second air column 12 is arranged in the second trap slot 10 , and the third flow channel 8 communicates with the first trap slot through the first air column 11 . 9. The fourth flow channel 6 communicates with the second trap groove 10 through the second air column 12 . Once the reagent in the liquid storage tank flows back to the slender flow channel, it will first be poured into the second trap tank through the fourth flow channel. At this time, the second gas column is higher than the bottom surface of the second trap tank, and only the After the liquid level reaches a certain height, it will reach the top opening of the air column, and then continue to flow back into the third flow channel. The first trap groove is connected to the third flow channel. As mentioned above, the liquid level needs to exceed the first air column to Continuing forward, reverse flow occurs, so the gas-liquid isolation trap prevents liquid from flowing back into the air intake.
所述盒体1上设置有与进气口2连通的进气仓13，所述进气仓13通过设置在盒体1下底面的储气仓14连通第一流道5。气体由进气口进入进气仓再经储气仓进入细长流道，进气仓和储气仓起到第一次均压的作用。The box body 1 is provided with an air intake bin 13 that communicates with the air inlet 2 , and the intake bin 13 communicates with the first flow channel 5 through an air storage bin 14 arranged on the bottom surface of the box body 1 . The gas enters the air intake chamber from the air inlet and then enters the slender flow channel through the air storage chamber. The air intake chamber and the air storage chamber play the role of the first pressure equalization.
所述第一流道5与第二流道7之间通过设置在盒体1下底面的溢流槽15连通。溢流槽的作用同样是进一步避免液体试剂继续向前倒流。The first flow channel 5 and the second flow channel 7 communicate with each other through the overflow groove 15 provided on the lower bottom surface of the box body 1 . The function of the overflow groove is also to further prevent the liquid reagent from continuing to flow backward.
所述溢流槽15通过设置在盒体1上顶面的第三陷阱槽16与第二流道7连通，所述第三陷阱槽16内设置有第三气柱17，所述溢流槽15通过第三气柱17连通第三陷阱槽16。此处的第三陷阱与前述第一和第二陷阱的功能相同。The overflow groove 15 communicates with the second flow channel 7 through a third trap groove 16 arranged on the top surface of the box body 1 , and a third air column 17 is arranged in the third trap groove 16 . 15 communicates with the third trap groove 16 through the third air column 17 . The third trap here has the same function as the aforementioned first and second traps.
所述第二流道7通过设置在盒体1上顶面的海绵槽18与第三流道8连通，所述海绵槽18内设置有吸水海绵。吸水海绵可以过滤气体，同时，当液体试剂倒吸入海绵槽时，吸水海绵会吸收液体试剂，提高防回流效果。The second flow channel 7 communicates with the third flow channel 8 through a sponge groove 18 provided on the top surface of the box body 1 , and the sponge groove 18 is provided with a water-absorbing sponge. The absorbent sponge can filter the gas, and at the same time, when the liquid reagent is sucked into the sponge tank, the absorbent sponge will absorb the liquid reagent to improve the anti-reflux effect.
所述第二陷阱槽10通过连接流道19连通储液槽4。连接流道一方面可以提高液体倒吸的难度，另一方面可以进一步起到气体均压的作用。The second trap tank 10 communicates with the liquid storage tank 4 through the connecting flow channel 19 . On the one hand, the connecting flow channel can improve the difficulty of liquid sucking back, and on the other hand, it can further play the role of gas pressure equalization.
对于如图1和图2所示的试剂盒，其储液槽为两个，其分别通过相同的结构与储气仓连接，气体由进气口经进气仓进入储气仓后一分为二，分别进入各自的流道。气体首先由第一流道进入溢流槽，溢流槽可以为多个连续，经连续的溢流槽后通过第三气柱进入第三陷阱槽。气体由第三陷阱槽继续向前，经第二流道后进入海绵槽，再由海绵槽进入第三流道，第三流道连通第一气柱将气体引入第一陷阱槽内。气体再由第一陷阱槽经第四流道通入第二气柱进入第二陷阱槽，最终由连接流道与储液槽连通。For the kit as shown in Figure 1 and Figure 2, there are two liquid storage tanks, which are respectively connected to the gas storage chamber through the same structure. Second, enter their respective runners. The gas first enters the overflow groove from the first flow channel, and the overflow grooves can be a plurality of consecutive ones, and then enter the third trap groove through the third gas column after passing through the continuous overflow grooves. The gas continues forward from the third trap groove, enters the sponge groove after passing through the second flow channel, and then enters the third flow channel from the sponge groove. The third flow channel is connected to the first air column to introduce the gas into the first trap groove. The gas then passes through the first trap groove through the fourth flow channel into the second gas column and enters the second trap groove, and finally communicates with the liquid storage tank through the connecting flow channel.
当然，储液槽也可以是多个，分别经相同结构与储气仓连接，细长流道以及气液隔离陷阱的设置有效避免回流的发生，即便发生回流，多种试剂也难以相互混合，实现一个试剂盒储存多种试剂的效果。Of course, there can also be multiple liquid storage tanks, which are respectively connected to the gas storage tank through the same structure. The setting of slender flow channels and gas-liquid isolation traps can effectively avoid the occurrence of backflow. Even if backflow occurs, it is difficult for various reagents to mix with each other. Achieve the effect of storing multiple reagents in one kit.
本发明的各个流道和隔仓均是通过在盒体内部、上顶面或下底面设置隔板分隔而成，在通过在隔板上覆盖塑封膜而成，由于储液槽的容积较大，在充入液体时会将塑封膜顶起而鼓包，因而在储液槽内设置有支撑板20，支撑板的顶部与塑封膜固定。Each flow channel and compartment of the present invention are separated by arranging partitions inside the box body, the upper top surface or the lower bottom surface, and by covering the partitions with plastic sealing films, because the volume of the liquid storage tank is relatively large. , when the liquid is filled, the plastic film will be lifted up and bulged, so a support plate 20 is arranged in the liquid storage tank, and the top of the support plate is fixed with the plastic film.
