Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail. These accompanying drawings are simplified schematic diagrams, only illustrating the basic structure of the utility model in a schematic way, and the direction of this specific implementation is based on the direction of Fig. 1.

The utility model provides an integrated saliva collector, comprising a funnel 1, a collection bottle 2, and a collection bottle cap 3;

Wherein, funnel 1 comprises upper casing 11, sealing structure 12, output pipe 13, and output pipe 13 is arranged on the lower end of upper casing 11, and upper casing 11 communicates with output pipe 13, and the opening end of upper casing 11 is provided with There is a section of arc structure 111, so that when the collection funnel touches the position of the lower lip, the lip and the arc structure 111 of the upper casing can fit together better. Preferably, the arc structure 111 is arranged in the middle of the opening end of the upper casing position, a sealing structure 12 is provided at the bottom of the upper housing 11, and the sealing structure 12 forms a detachable connection with the top of the collection bottle, which can be a threaded connection or an interference fit or a snap connection. Of course, it is not limited to the above-mentioned embodiment. Take the threaded connection as an example, the sealing structure 12 is similar in structure to the collection bottle cap 3, the inside of the sealing structure 12 is provided with an internal thread, and the output tube 13 is provided with a scale line 131, the amount of saliva can be determined by the scale line, so that the amount of saliva can be determined according to Collect the amount of saliva that is needed without over or under collection.

The upper end of the collection bottle 2 is open, and the bottom end is sealed. The opening of the funnel 1 and the collection bottle 2 is sealed and connected by a sealing structure 12, so that the preservation solution in the collection bottle 2 will not leak out from the opening of the collection bottle. The bottom end or inner wall of the collection bottle 2 forms a plugging portion 21, which forms a sealed and detachable connection with the output pipe 13 of the funnel. As shown in Figure 1-2, the plugging portion 21 can be formed toward the inside of the collection bottle A protrusion, the two ends of the protrusion have a gap with the inner wall of the collection bottle 2, the preservation solution is pre-placed in the collection bottle 2, and evenly distributed at the root of the plugging part 21, the plugging part 21 is connected to the bottom of the output pipe 13 of the funnel 1 Cooperate to form a seal, which can be an interference fit, or other matching methods, so that the plugging part 21 and the output pipe of the funnel form a seal to prevent the preservation solution from leaking out of the funnel. As shown in Figure 5, the plugging part 21 can also be a collection The concave cavity of the bottle 2 is concave downward, and the concave cavity just forms a sealed fit connection with the funnel output pipe 13. As shown in Figure 6, the blocking part 21 can also be a convex part upward at the bottom of the collection bottle, and the upper part of the convex part corresponds to the funnel. The position of the output pipe 13 forms a groove downwards, and the groove forms a sealing fit connection with the output pipe. Of course, the structure of the blocking part 21 is not limited to the above-mentioned structure, and the inner wall of the collection bottle and the blocking part 21 can form a sealing fitting connection structure, all belong to the protection scope of the present utility model.

The collection bottle cap 3 is detachably connected to one end of the collection bottle 2, which can be a threaded connection, an interference fit or a snap connection, but is not limited to the above connection methods. Initially, the collection bottle cap 3 can be screwed to the collection bottle 2 When the collection of saliva is completed, the collection bottle cap 3 is unscrewed, and the collection bottle cap 3 is screwed to the bottom of the collection bottle 2 to form a seal.

Preferably, the collection bottle and the output tube of the funnel are transparent, and the amount of internal preservation fluid and saliva can be seen.

The state of transportation is that the funnel and the collection bottle are screwed tightly, the collection bottle cap is buckled at the bottom of the collection bottle, and the three parts are combined into one.

When collecting the saliva sample, spit the saliva into the funnel, because the output tube 13 of the funnel 1 is sealed with the storage bottle 2 at the sealing part 21, the saliva accumulates in the funnel 1, and when it reaches the position indicated by the scale line, rotate the funnel , the funnel is separated from the storage bottle. During the separation process, the seal between the funnel output tube 13 and the collection bottle 2 is broken, and the saliva in the funnel 1 will flow into the collection bottle 2 to be mixed with the storage solution. After the saliva in the funnel flows out, Take out the funnel for proper disposal, this is the only part to be discarded during the harvesting process.

The bottle cap of the preservation bottle is buckled at the bottom of the bottle, and the process of saliva collection is completed after taking off the cap of the preservation bottle and tightening it. The whole collection process is simple.

Embodiment two

As shown in FIG. 7 , considering that the top of the funnel 1 is provided with an opening, dust and other sundries can easily enter the funnel, which will affect the detection results and be unhygienic. Therefore, this embodiment is implemented in the following manner.

Funnel 1 comprises upper casing 11, output pipe 13, and wherein output pipe 13 is arranged on the lower end of upper casing 11, and upper casing 11 communicates with output pipe 13, and funnel 1 is arranged in the collecting bottle 2, and the upper casing 11 The top is flush with the mouth of the collection bottle or slightly higher than the mouth of the bottle. The collection bottle cap 3 in this embodiment is detachably arranged on the top of the collection bottle 2, so that the funnel 1 and the collection bottle 2 are sealed together. When collecting, Unscrew the cap of the collection bottle and spit saliva into the funnel 1. After the collection is completed, unscrew the funnel and discard it. Part 21 is sealed and connected, and the bottle cap is tightened to seal the collection bottle.

Others are the same as the first embodiment, and will not be described here.

The above is only the preferred implementation of the utility model, the utility model is not limited to the above implementation, there may be local minor structural changes in the implementation process, if the various changes or modifications of the utility model do not depart from the present invention If the spirit and scope of the utility model belong to the claims of the utility model and the equivalent technical scope, the utility model also intends to include these changes and modifications.
