Description

saliva collector

technical field

The utility model relates to a saliva collector, in particular to a saliva collector for gene detection.

Background technique

For genetic testing, the existing sample collection method is mainly to take venous blood, which is traumatic and requires professionals to collect. In addition, blood collection is not suitable for special populations such as newborns, which limits the application of this method.

With the gradual deepening of the application of genetic testing technology, the special requirements for sample collection are also highlighted, and there is an urgent need for more convenient and easy-to-use sample collection methods. Saliva sample collection is a non-invasive, easy-to-operate and effective method.

At present, the collection of saliva samples is divided into two methods: oral scraper and direct saliva collection. Professional saliva collection products such as ORAgene and DNAguard have also appeared in saliva collectors, which have an important impact on the collection of saliva DNA. However, there are some technical deficiencies in these acquisition devices. First of all, ORAgene's saliva collector adopts a glass tube design, which is not as convenient as a plastic tube. ORAgene's saliva collection funnel has a long and narrow oval design. When collecting saliva, the mouth cannot be fully opened, and it will be inconvenient to spit out saliva. ORAgene's saliva collector adopts a unique penetrating design for preservation solution, which can effectively wash away the saliva on the funnel, but the puncture point for piercing the preservation solution only exists on one side of the funnel, and cannot effectively wash away the saliva spit on the other side , affecting the total amount of saliva collected. The saliva collection device of DNAgard adopts the mechanism of separating spit saliva and adding preservation solution. The flushing of saliva is more thorough during collection, but the separate design will increase the operation steps and cause inconvenience.

Utility model content

The purpose of the utility model is to overcome the above problems in the prior art and provide a saliva collector.

In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the utility model is realized through the following technical solutions:

A saliva collector, comprising a funnel with a round mouth and an upper cover matched with it, the upper cover includes a cavity storing a preservation solution, the cavity is sealed by a film, and a bump for supporting the film is arranged in the cavity , at least one vertical thorn is vertically arranged in the funnel, and when the upper cover is closed, the vertical thorn can pierce the film.

Preferably, the bumps are cross-shaped.

Further, a collection pipe is connected below the bottom of the funnel.

Further, the upper cover is connected with the funnel through the connecting piece on the side of the funnel.

Preferably, there are two vertical thorns, the vertical thorns are close to the side wall of the funnel, one is located on one side of the connecting piece, and the other is opposite to it.

Preferably, the funnel is connected to the collection pipe through threads.

The beneficial effects of the utility model are:

1. The funnel part of the saliva collector described in the utility model adopts the design of a round mouth, which is more suitable for the mouth shape than the oval shape of the prior art, and can make the process of spit saliva more smooth; the upper cover part is provided with a cross-shaped The bumps can give the film better support, make it easier for the vertical thorns on the side wall of the funnel to pierce the film, make the preservation solution more fully flush the saliva on the funnel wall, and be more convenient and easy to use as a whole.

2. The utility model also has the following advantages: through painless and non-invasive sample collection, patient care is improved and the degree of cooperation is improved; the cost of bloodletting is eliminated; it is very suitable for children or patients who do not cooperate with blood collection; the use is suitable for Qualcomm The mode of high-volume processing improves efficiency, greatly simplifies sample processing, and reduces processing errors; sample transportation and storage are convenient; samples can be mailed using the standard postal system; DNA collected from saliva is equivalent to DNA collected from blood in terms of downstream applications Advantages such as DNA.

The above description is only an overview of the technical solution of the utility model. In order to understand the technical means of the utility model more clearly and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiment of the utility model with accompanying drawings. back. The specific embodiment of the utility model is given in detail by the following examples and accompanying drawings.

Description of drawings

The accompanying drawings described here are used to provide a further understanding of the utility model and constitute a part of the application. The schematic embodiments of the utility model and their descriptions are used to explain the utility model and do not constitute improper limitations to the utility model. In the attached picture:

Figure 1 is a schematic diagram of the overall structure of the saliva collector.

Explanation of symbols in the figure: 1. funnel, 2. upper cover, 21. cavity, 22. film, 23. bump, 3. vertical thorn, 4. collecting tube, 5. connecting piece.

Detailed ways

The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

Referring to FIG. 1 , a saliva collector includes a funnel 1 with a round mouth and an upper cover 2 matched therewith. The upper cover 2 is connected to the funnel 1 through a connecting piece 5 on the side of the funnel 1 . The upper cover 2 includes a cavity 21 storing the preservation liquid, the cavity 21 is sealed by a film 22, and a cross-shaped protrusion 23 for supporting the film 22 is arranged in the cavity 21, and the inner side of the funnel 1 is Two vertical thorns 3 are vertically arranged on the wall, one is located on one side of the connecting piece 5, and the other is opposite to it, and the bottom of the funnel 1 is threadedly connected with a collection pipe 4

Initially, the upper cover 2 is in an open state, and the collecting tube 4 is screwed under the funnel 1 . When sampling, point the mouth at the funnel 1 and spit out the saliva, cover the upper cover 2 firmly, and hear the piercing sound. At this time, the vertical thorn 3 pierces the film 22, and due to the support of the bump 23, the piercing becomes more severe. Easy, the preservation solution in the cavity 21 leaks out, the preservation solution fully washes the saliva on the wall of the funnel, flows into the collection tube 4 below, and completes the transfer of the saliva to the collection tube 4. Unscrew the collection tube 4, cover the collection tube cap, discard the funnel, and complete the collection.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
