Technical Field

The utility model relates to the field of medical treatment, especially, relate to a disposable virus sampling burette.

Background

A virus sampling dropper is a tube for storing and transporting microorganism samples, and can be used for collecting, storing and transporting clinical respiratory tract pathogen specimens, clinical intestinal bacteria specimens, clinical respiratory tract and intestinal virus, chlamydia, mycoplasma and ureaplasma specimens. The sealing and the use of the sampling dropper play an important role in the accuracy of the detection of the virus.

When the existing disposable virus sampling tube is used, a swab needs to be put into the sampling tube with liquid, the cover of the sampling dropper needs to be opened for extracting the liquid in the sampling tube for testing, and the sampling tube has two problems: 1. the cover of the sampling tube is easy to cause secondary pollution in the process of opening and extracting, viruses in certain environments pollute samples, and meanwhile, the viruses threaten the physical health of inspection personnel and the surrounding environment; 2. after the sample to be detected is sucked, the sample can remain on the sampling suction head due to adhesiveness, and when the suction head is discarded, the laboratory is easily polluted; 3. when a sample to be detected is sucked, liquid in the sampling pipe is easy to spill.

Disclosure of Invention

In view of the existing problems, the utility model aims to provide a disposable virus sampling dropper, which can realize the detection without extracting the sample in the sampling dropper, avoid the cover opening and the liquid transfer pollution to a great extent, and reduce the harm level when the biohazard sample is operated; meanwhile, the blockage of the pipe orifice during sample dripping can be avoided.

In order to achieve the above object, the utility model adopts the following technical scheme:

a disposable virus sampling dropper is characterized in that: including body and combination tube cap, the body passes through one-level thread structural connection with the combination tube cap, the combination tube cap includes one-level tube cap and second grade tube cap, connects through second grade thread structural connection between the combination tube cap.

Preferably, the primary pipe cover and the secondary pipe cover are both provided with internal threads.

Preferably, an easy-tearing point connection is arranged between the primary pipe cover and the secondary pipe cover.

Preferably, a filter screen is arranged in the middle of the inside of the primary pipe cover.

Preferably, a drip nozzle is integrally arranged on the upper top surface of the primary pipe cover.

Preferably, one-level helicitic texture sets up the mouth of pipe department at the body, one-level helicitic texture and the interior screw-thread fit of one-level tube cap, second grade helicitic texture sets up the outside of dripping the mouth, second grade helicitic texture and the interior screw-thread fit of second grade tube cap.

Preferably, a sealing column matched with the inner diameter of the drip nozzle is arranged in the secondary tube cover.

Preferably, the first-stage thread structure is a forward external thread, the second-stage thread structure is a reverse external thread, the forward external thread is a thread structure which is unscrewed when the first-stage pipe cover rotates forward relative to the pipe body, and the reverse external thread is a thread structure which is screwed when the second-stage pipe cover rotates forward relative to the first-stage pipe cover.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses a disposable virus sampling burette through setting up the combination tube cap, can realize putting into the body back with the swab, only need open the second grade tube cap during the detection, inverts the body and extrudees, will wait to examine the sample and drip out, need not uncap the absorption and can detect. Therefore, the leakage of virus liquid in the sample tube is greatly reduced, and the laboratory pollution and the occupational exposure risk of operators in working are reduced. Meanwhile, the related consumables such as a pipette and a suction head and the cost for waste treatment are saved.

2. The utility model discloses a disposable virus sampling burette through set up filter equipment in the tube cap, avoids the drip nozzle to be plugged up by the swab.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example (b):

referring to the attached drawings 1-3, the disposable virus sampling dropper comprises a tube body 1 and a combined tube cap, wherein the tube body 1 is connected with the combined tube cap through a first-level thread structure, and the combined tube cap is connected with the combined tube cap through a second-level thread structure. The tube body 1 is cylindrical and made of medical plastics, and slight elastic deformation can occur during pressing.

1. In this embodiment, the combination tube cap includes one-level tube cap 3 and second grade tube cap 6, one-level tube cap 3 and second grade tube cap 6 all are provided with the internal thread. Set up between one-level tube cap 3 and the second grade tube cap 6 and easily tear a 8 connections, can rotate second grade tube cap 6 during the use, easily tear a 8 disconnection of point. The upper top surface of the first-level pipe cover 3 is integrally provided with a drip nozzle 4, the drip nozzle 4 is of a hollow cylindrical structure, the inner diameter of the drip nozzle 4 is about 2-4mm, and the dripping speed is about 40-50 ul/drip. The intermediate position in the one-level tube cap 3 is provided with filter screen 7, and filter screen 7 is medical plastics material, and with 3 integrative settings of one-level tube cap, can avoid the swab to plug up drip nozzle 4, the position that filter screen 7 set up is greater than the mouth of pipe height of body 1, can not influence the mouth of pipe of body 1 and screw up with 3 one-level tube caps.

In this embodiment, be provided with in the second grade pipe cap 6 with drip mouth 4 internal diameter complex sealed post 9, sealed post 9 and the internal diameter cooperation of drip mouth 4, sealed post 9 inserts drip mouth 4 and then screws second grade pipe cap 6, and then sealing connection between second grade pipe cap 6 and the one-level pipe cap 3.

In this embodiment, the mouth of pipe department of body 1 is provided with the one-level helicitic texture with 3 interior screw-thread fit of one-level tube cap, 4 outsides of drip nozzle are provided with the second grade helicitic texture with 6 interior screw-thread fit of second grade tube cap. The one-level helicitic texture is forward external screw thread 2, the second grade helicitic texture is reverse external screw thread 4, forward external screw thread 2 is the helicitic texture that unscrews when 1 forward rotation of relative body of one-level tube cap 3, reverse external screw thread 5 is the helicitic texture of screwing up when 3 forward rotations of relative one-level tube cap of second grade tube cap 6. Therefore, when the second tube cap 6 is unscrewed, the first tube cap 3 is screwed tightly, and the problem of leakage caused by unscrewing the first tube cap 3 when the user unscrews the second tube cap 6 and drips a sample to be detected through the dripping nozzle 4 can not occur.

The utility model discloses a principle and use flow:

when the sampling dropper is used, the tube cover is separated from the tube body 1 by positively rotating the primary tube cover 3, then a swab is placed in the tube body 1 in the sampling dropper with liquid, and the primary tube cover 3 is reversely rotated to be matched with the tube body 1 in a screwing mode. Then, the virus sampling dropper is conveyed to a detection place, the secondary tube cover 6 is rotated anticlockwise relative to the primary tube cover 3, the easy-to-tear point 8 is disconnected, then the secondary tube cover 6 is unscrewed, the middle part of the tube body 1 is lightly pressed, and liquid with a swab is dripped on a detection instrument through the dripping nozzle 4 to start detection.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
