Description

Separation and reuse biological sample collection swab

Technical Field

The invention relates to the technical field of biology, in particular to a separated and reused biological sample collecting swab.

Background

At present, swab sampling technology is mature, mainly comprises throat swabs, nasal swabs, throat swabs and the like, secretions are collected through sterile swabs, and are immediately put into preservation solution or reaction solution, so that retrospective diagnosis is made through pathogen detection.

However, the existing swabs directly break the swab rod after sampling, which causes a great deal of waste of the swab rod, and the collected sample is easy to spill out with relatively strong force during breaking, and meanwhile, the existing swabs have relatively few samples, which also easily causes pollution of the sampled sample.

Disclosure of Invention

The present invention is directed to a separate and reusable biological specimen collection swab that addresses the shortcomings of the prior art. The structure is relatively simple and reasonable. The relative manufacturing cost is low.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a biological sample collection swab is recycled in separation, includes the mobile jib, the one end symmetry of mobile jib is equipped with the fastening groove, the inside grafting of mobile jib has the telescopic link, the one end of telescopic link extends to the outside of mobile jib, the carriage release lever is installed to the other end of telescopic link, the fastening groove is run through at the both ends of carriage release lever, the position grafting that mobile jib one end was equipped with the fastening groove has the swab pole of wiping, wipe the one end of swab pole to install and wipe the swab head, the middle part of wiping the swab head is equipped with the cavity, wipe the surface of swab head equidistant a plurality of and the communicating through-hole of cavity of being equipped with.

Preferably, one end of the main rod is provided with an inward chamfer.

Preferably, the size of one side of the through hole close to the cavity is larger than that of one side far away from the cavity.

The invention provides a separated and reused biological sample collecting swab, which has the beneficial effects that: the invention has the advantages that the wiper rod and the main rod can be separated, only the wiper head needs to be wasted after separation, the telescopic rod and the main rod can be reused, the waste amount is greatly reduced, the wiper rod and the main rod can be separated only by pushing the telescopic rod, the labor is saved, the sample on the wiper head can be prevented from splashing, the cavity and the through hole can be used for sampling more samples, the through hole is more on the outer surface of the wiper head, the inner side of the through hole is in a closed state under the condition that the wiper head is not stressed, the isolation between the cavity and the through hole can be ensured, and the sample in the cavity can also be prevented from being polluted.

Drawings

FIG. 1 is a schematic perspective view of a separated and reused biological specimen collection swab according to the present invention;

FIG. 2 is a schematic cross-sectional view of a detached and reused biological specimen collection swab of the present invention;

FIG. 3 is a schematic diagram of a partial enlarged structure of a separating and reusing biological sample collecting swab FIG. 2 according to the present invention.

In the figure: the mop comprises a telescopic rod 1, a main rod 2, a mop head 3, a fastening groove 4, a mop rod 5, a cavity 6, a chamfer 7, a moving rod 8 and a through hole 9.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-3, a separated and reused biological sample collecting swab comprises a main rod 2, wherein one end of the main rod 2 is provided with an inward chamfer 7, so that a swab rod 5 can be conveniently inserted into the main rod 2, and the use is more convenient.

The one end symmetry of mobile jib 2 is equipped with fastening groove 4, the inside grafting of mobile jib 2 has telescopic link 1, the one end of telescopic link 1 extends to the outside of mobile jib 2, carriage release lever 8 is installed to the other end of telescopic link 1, fastening groove 4 is run through at the both ends of carriage release lever 8, the position grafting that 2 one end of mobile jib 2 was equipped with fastening groove 4 has rotor rod 5 of wiping, the external diameter size of wiping rotor rod 5 is greater than the size of 2 internal diameters of mobile jib, rotor rod 2 can tightly clip rotor rod 5 of wiping, make wipe rotor rod 5 firm more.

The mop head 3 is arranged at one end of the mop rod 5, the cavity 6 is arranged in the middle of the mop head 3, a plurality of through holes 9 communicated with the cavity 6 are arranged on the surface of the mop head 3 at equal intervals, the size of one side, close to the cavity 6, of each through hole 9 is larger than that of one side, far away from the cavity 6, of each through hole 9, the cavity 6 can be isolated from the outside when the mop is not used, pollution can be effectively prevented, and the outer surface area of the mop head 3 can be increased due to the large outer side of each through hole 9, so that more samples can be taken.

With a distance of 1mm between adjacent through holes 9, the number of through holes 9 will be greater, thereby increasing the outer surface area of the wiper head 3.

The working principle is as follows: when the collection is needed, the swab rod 5 is inserted into one end of the main rod 2, the main rod 2 clamps the swab rod 5 under the action of the fastening groove 4, the biological sample collection of the swab head 3 can be carried out, the swab head 3 is stressed during collection, the through hole 9 is opened, the sample enters the surface of the swab head 3 and the cavity 6, the collection of the sample is completed, after the collection, the swab head 3 is not in a closed state at the inner side of the through hole 9 under the stress condition, the isolation between the cavity 6 and the through hole 9 can be ensured, the sample in the cavity 6 can be prevented from being polluted, the swab rod 5 and the main rod 2 are separated, only the telescopic rod 1 needs to be pushed, labor is saved, and the sample on the swab head 3 can be prevented from splashing.
