Description

A saliva collector with sealed storage performance

technical field

The utility model belongs to the technical field of body fluid collection and detection, in particular to a saliva collector for saliva collection with sealed storage performance.

Background technique

Saliva is a complex mixture that contains not only various proteins, but also DNA, RNA, fatty acids, and various microorganisms. Studies have found that various protein components in blood also exist in saliva, and saliva can reflect changes in the levels of various proteins in blood. Therefore, the diagnosis of the disease can be carried out through the detection of saliva. Currently, saliva has been used to detect HIV and HBV viruses, as well as various drugs such as cocaine and alcohol. The research on saliva testing has just started, and the sensitivity, specificity, reproducibility and correlation with existing diagnostic criteria still need to be further improved.

The commonly used saliva collection method is mainly the traditional direct sampling method, such as using a sterile cotton swab to dip the sample in the mouth of the sampled person, or flowing out naturally from the mouth of the sampled person. The former method is simple, but the sampling volume is small, and direct sampling is easy to bring out the oral residue, which is easy to affect the detection effect, and the saliva sample on the cotton swab is not easy to be preserved, and the waiting time for detection is short. The latter cannot obtain more saliva in a short period of time, and the direct sampling method is also easy to carry out residues, which affects the detection effect.

In view of the above-mentioned defects, the designer actively researches and innovates in order to create a saliva collection device that is convenient for saliva collection and sealed preservation, so that it has more industrial utilization value.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. For example, it is not used to limit the scope of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

Referring to FIG. 1 , the utility model has a saliva collector with sealed storage performance, including a collection funnel 1 , a collection tube 2 , and a filter layer 3 . The collection tube 2 is divided into two parts, an upper tube body 21 and a lower tube body 22, wherein the lower end of the upper tube body 21 is provided with an integrally formed first cover 23, and the upper end of the lower tube body 22 is provided with an integrally formed second cover body twenty four. A first through hole 25 is opened in the first cover 23 , and a second through hole 26 is opened in the second cover 24 corresponding to the first through hole 25 . Due to this ingenious structural design, as shown in Fig. 2 and Fig. 3, the first cover body 23 and the second cover body 24 control the overlapping or staggering of the first through hole 25 and the second through hole 26 through relative rotation, as shown in Fig. 2 shows a schematic view of the split structure of the overlapping state of the first cover 23 and the second cover 24, and FIG. 3 shows a schematic view of the split structure of the state of the first cover 23 and the second cover 24 being staggered.

Specifically, the upper tube body 21 and the lower tube body 22 are connected by the rotation central shaft 4 , and the positions of the upper tube body 21 and the lower tube body 22 are limited by the locking nut 5 sleeved on the rotation center shaft 4 . A sealing ring 6 is provided on the outer ring connecting the first cover body 23 and the second cover body 24 . Preferably, the filter layer 3 can be set as a composite filter layer, including a sponge coarse filter layer 31 and a gauze fine filter layer 32, so as to enhance the filtering effect on saliva. The filter layer 3 can be a movable structure, and it is placed at the threaded connection position of the collection funnel 1 and the collection tube 2, which is convenient for replacement. As shown in FIG. 1 , the opening end of the collection funnel 1 has an arc structure, which fits better around the mouth of the human body, and facilitates the flow of saliva from the person whose saliva is collected. The collection funnel 1 and the collection tube 2 are connected by thread rotation, which is not only convenient for the person whose saliva is collected to use the collection funnel 1 to flow out the saliva, but also facilitates the removal of the collection funnel 1 after the saliva collection is completed, which is beneficial to the collection tube 2 for storage.

When the saliva collector with sealed storage performance of the utility model is working, the collection funnel 1 and the collection tube 2 are connected together through screw rotation, and the filter layer 3 can be placed at the screw rotation connection position to collect saliva from the person whose saliva is collected. Before the saliva flows into the collection tube 2, rotate the upper tube body 21 and the lower tube body 22, so that the first cover body 23 and the second cover body 24 are in the overlapping state shown in Figure 2, that is, the upper tube body 21 and the lower tube body 22 is a connected state, saliva drips into the collection tube 2, flows into the lower tube body 22 through the upper tube body 21, the first through hole 25 and the second through hole 26, and when the saliva drips into the collection tube 2, rotate the upper tube again body 21 and lower tube body 22, so that the first cover body 23 and the second cover body 24 are in the staggered state shown in Fig. The saliva inside is isolated from the external environment.

Therefore, the utility model makes the utility model device convenient to use in the process of collecting saliva through reasonable structural design, can effectively filter the residue in the saliva object, and the split design of the collection tube can isolate the air as much as possible and prolong the saliva sample. The storage time limit is convenient for subsequent sample testing. The utility model still has multiple implementation modes, and all technical solutions formed by equivalent transformation or equivalent transformation all fall within the protection scope of the utility model.
