Description

A kind of saliva sample collection container

technical field

The invention belongs to the field of medical testing, and relates to a sample collection device, in particular to a saliva sample collection container.

Background technique

Human saliva contains exfoliated cells of the oral mucosa. Collecting saliva as a DNA sample is widely used because it is non-invasive and simple. What existing saliva collector has is to collect saliva with cotton swab, more loaded down with trivial details. The existing invention patent "Double-head Saliva Collector" (China Patent No. 200620123835.7) consists of three parts: a threaded sampling rod, a cylindrical main pipe and a sample outlet cover. The sampling rod is composed of three structures, the upper cover, the plunger and the absorbent cotton. When sampling, put the absorbent cotton end of the sampling rod into the mouth to make it stained with saliva sample, then put the sampling rod back into the tubular main tube, tighten the bottle cap, unscrew the sample outlet cap, and squeeze out the sample. The sample is collected with absorbent cotton, which is easy to be polluted and the operation is cumbersome.

Preferably, the transition structure includes a first connection part connected to the pipe body and a second connection part connected to the collection structure, the second connection part is provided with a connection groove, and the collection structure is provided with The connection protrusion which can be inserted into the connection groove and move in the connection groove has simple structure and convenient operation.

Preferably, the connecting groove includes an adjusting groove arranged along the circumferential direction of the second connecting part and a vertical groove communicating with the adjusting groove.

Preferably, the connecting grooves are two adjusting grooves and two corresponding vertical grooves arranged symmetrically on the second connecting part.

Preferably, the outer circumference of the first through hole is provided with a first inner groove, and a sealing ring is arranged in the first inner groove.

Preferably, the isolation plate is further provided with a ventilation hole; in a sealed state, the ventilation hole and the second through hole are located directly below the sealing area. The setting of the air hole can ensure that the sample can enter the tube body smoothly, and when sealing, it can achieve a good sealing effect with the assistance of the sealing area to ensure that the sample will not leak out.

Preferably, a sleeve is provided outside the pipe body, and the sleeve is connected to the first connecting portion of the transition structure. The saliva sample will look unsanitary and unsightly, and the setting of the tube sleeve can avoid this problem.

Preferably, the inner surface of the first connecting part is provided with internal threads, the outer surface of the upper part of the pipe body is provided with external threads that cooperate with the internal threads, and the connection between the first connecting part and the sleeve are connected by external connectors.

Preferably, the outer connecting piece includes a connecting buckle arranged on the outer surface of the first connecting part and a buckle groove arranged on the inner surface of the sleeve, which are convenient for connection and disassembly.

By implementing the above-mentioned technical scheme, the present invention has the following beneficial effects: the present invention can conveniently, smoothly and hygienically store samples into the tube body, and ensure that the samples will not be polluted through multi-stage collection structures and transition structures, and the overall structure is simple , Sampling operation is also convenient, suitable for large-scale promotion.

detailed description

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in accompanying drawings 1 and 2, a saliva sample collection container includes a tube body 1 for storing samples and a collection structure 2 for collecting samples, and a collection structure 2 is arranged between the tube body 1 and the collection structure 2 The collected samples are drained to the transition structure 3 in the tube body 1. The transition structure 3 includes a first connection part 301 connected to the tube body 1 and a second connection part 302 connected to the collection structure 2. The transition structure 3 is provided with isolation The plate 31 is provided with a second through hole 311 on the isolation plate 31 ; the first through hole 21 and the sealing area 22 are provided on the lower surface of the collecting structure 2 . The rotatable connection between the collection structure 2 and the transition structure 3 in the circumferential direction of the transition structure 3 is realized by the following scheme: the second connection part 302 is provided with a connection groove 303, including along the second connection part Two symmetrical adjustment grooves 3031 and two vertical grooves 3032 respectively communicated with each adjustment groove 3031 are arranged in the circumferential direction of 302 . The collecting structure 2 is provided with a connection protrusion 201 , the connection protrusion 201 moves down along the vertical groove 3032 into the adjustment groove 3031 , and can move along the adjustment groove 3031 in the circumferential direction of the second connection part 302 . By moving in the adjustment groove 302, the second through hole 311 is aligned with the first through hole 21 or the sealing area 22. When the second through hole 311 is aligned with the first through hole 21, the sample can flow into the tube Inside the body 1; and when the second through hole 311 is aligned with the sealing area 22, the communication between the tube body and the outside world is prevented, and the sample stored in the tube body 1 will not flow out.
