Description

Saliva collector

Technical Field

The utility model relates to a medical instrument, especially a saliva collector.

Background

Saliva sample collection is a method for obtaining DNA/RNA without harm and pain to human bodies. The method does not cause any discomfort to the collected person, is easy to accept, and can expand the sampling range of gene research to the maximum extent. The existing saliva collector mainly comprises a collecting funnel, a collecting tube and a storage tube. The preservative is placed in the preservation tube, saliva collected by the collection funnel flows into the collection tube, the saliva in the collection tube is poured into the preservation tube, so that the saliva is mixed with the preservation solution, the mixture can be preserved at room temperature for a long time, and the DNA/RNA of the saliva sample is prevented from being damaged. However, the saliva of the existing saliva collector is mixed with the preservative, the operation process is complicated, and the sample is easily polluted.

SUMMERY OF THE UTILITY MODEL

In order to solve the above disadvantages, the present invention provides a saliva collector, which is easy and convenient to operate and can avoid contamination when mixing saliva with preservative. In order to solve the technical problem, the utility model adopts the technical scheme that the saliva collector is characterized in that the saliva collector consists of a collecting funnel and a collecting pipe, a preservative is arranged in the collecting pipe, a sealing film is arranged at the port of the collecting pipe, and a sealing pipe cover is arranged at the port of the collecting pipe; a connecting sleeve is fixedly arranged around the discharge port of the collecting hopper and is connected with the collecting pipe through threads; and a membrane breaking piece is arranged near the discharge port of the collection funnel and corresponds to the sealing membrane.

Preferably, the inner cavity wall of the collecting funnel is provided with quantitative marked scales. Is convenient for quantitatively collecting saliva.

Preferably, the feed inlet of the collection funnel is provided with a cover. The cover is covered to carry out subsequent operation after the collection is finished, and the pollution is avoided.

The utility model has the advantages that the collection and storage of the saliva are integrated, the operation is simple and convenient when the saliva is mixed with the preservative, and the pollution can be effectively avoided; and meanwhile, the using amount of the test tube is reduced, so that the cost of the disposable appliance is reduced.

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is further described in detail with reference to the accompanying drawings and the detailed description.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Drawings

FIG. 2 is a schematic diagram of a second view structure of the collection funnel;

FIG. 3 is a schematic view showing a split structure of the collecting tube and the sealing tube cover.

Detailed Description

Refer to the attached drawings to reflect the specific structure of the utility model. The saliva collector comprises collection funnel 1 and collecting pipe 2, collecting pipe 2 inner chamber device preservative 201, collecting pipe 2's port is equipped with seal membrane 202, and collecting pipe 2's port is equipped with sealed tube cap 203, and collecting pipe 2's port is equipped with external screw thread 204.

A connecting sleeve 102 is fixedly arranged around the discharge hole 101 of the collecting funnel 1, the connecting sleeve 102 is provided with an internal thread 107, and the connecting sleeve 102 is in threaded connection with an external thread 204 of the collecting pipe 2 through the internal thread 107. Two membrane breaking pieces 103 are symmetrically arranged near the discharge hole 101 of the collection funnel 1, and the membrane breaking pieces 103 are arranged corresponding to the sealing membrane 202. The inner cavity wall of the collection funnel 1 is provided with a mark scale 104 for quantitatively collecting saliva. The inlet opening 105 of the collection funnel is provided with a lid 106.

When the collecting funnel is used, the collecting tube 2 is in threaded connection with the collecting funnel 1, when the threads are screwed for connection, the threads are not continuously screwed when the resistance of the membrane breaking piece 103 blocked by the sealing membrane 202 is sensed, and the feed opening 101 of the collecting funnel 1 is blocked by the sealing membrane 202 at the moment, so that a tester can conveniently spit saliva into the collecting funnel 1 to finish quantitative collection; then the cover 106 is covered and the screw thread is continuously screwed with force, so that the cutting edge of the membrane breaking piece 103 rotates to break the sealing membrane 202, and the collected saliva falls into the inner cavity of the collecting pipe 2 to be mixed with the preserving fluid 201; then the collecting pipe 2 is withdrawn from the threaded connection of the collecting pipe 1 and the collecting funnel 1, the collecting funnel 1 is discarded, and the collecting pipe 2 is covered by a sealing pipe cover 203, so that the collecting pipe can be used as a sampling sample for preservation. The collection tube 2 and the sealing tube cover 203 may be in a threaded or nested fit. Disposal of the collection funnel 1 as medical waste.

The foregoing embodiments are merely for clarity of explanation, and are not to be construed as limiting the present invention. The utility model discloses have known multiple substitution or warp in this technical field, do not deviating from the utility model discloses under the prerequisite of essence meaning, all fall into the utility model discloses a protection scope.
