Description

Flocked swab with spherical head for DNA collection

Technical Field

The utility model belongs to biology experimental device field, specifically say, relate to a spherical head DNA gathers flocking swab.

Background

The collection of DNA need not involve collection equipment except through the hair sample at present, other similar to the sample to skin, blood, saliva all need use the sampling instrument, wherein generally adopt the swab to gather the collection to the collection of saliva, however current swab generally has winding, flocking and foaming three types, compares comprehensively, and current three types biological sampling swabs have following defects: (1) the winding, flocking or foaming swab heads are all distributed at one end of the swab rod along the long shaft of the swab rod, and the effective contact part of the swab head, which is flat or conical and a sampling part, is less than half of the whole swab head in actual use, so that a liquid sample cannot be effectively collected, and the effective adsorption capacity of the swab is reduced; the whole wiper rod is a round rod with the same size, is not easy to break, and the breaking heights cannot be the same, (3) the wiper head wrapped by winding or foaming materials is not firmly combined with the wiper rod, so that the wiper head is easy to fall off; (4) due to the angular shape of the flat or conical swab head, the tip may damage the sampling site. Therefore, it is highly desirable for those skilled in the art to design a swab that has a large contact area with the application site without losing the sampling site.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a flocked swab is gathered to spherical head DNA, mainly solve the winding that exists among the prior art or the foaming swab head easily drops and because swab head tip edges and corners damage sampling position to swab the difficult problem of rupture of pole.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

a flocked swab with a spherical head for DNA collection comprises a swab pipe sleeve and a swab testing device sleeved with the swab pipe sleeve; the swab testing device comprises a handle, a swab rod and a spherical flocked swab head, wherein the handle is in contact with a swab pipe sleeve, one end of the swab rod is inserted into the handle, and the spherical flocked swab head is fixed to the top of the other end of the swab rod; the mop comprises a mop rod, a handle and a mop rod, wherein the mop rod comprises a conical head mop rod, a middle section mop rod and three sections of mop rods which are sequentially connected, one end of the conical head mop rod is connected with a spherical flocking mop head, one end of each three section of mop rod is connected with the handle, and an inward-concave easy-to-fold part is arranged at the connection position of the middle section mop rod and the three sections of mop rods.

Further, the handle is divided into a handheld part and a sleeve part, wherein the diameter of the handheld part is larger than that of the sleeve part, and the sleeve part is connected with the three segments of the swab rods.

Furthermore, at least two sealing strips vertical to the swab rod are arranged on the sleeving part.

Preferably, the handle is provided with a plurality of cleats that are the same tendency as the swab wand.

Specifically, at least 3 arc-shaped pieces which have the same trend with the three segments of the wiper rods and are used for reinforcing the three segments of the wiper rods are arranged on the three segments of the wiper rods.

Compared with the prior art, the utility model discloses following beneficial effect has:

(1) the utility model discloses a spherical flocking swab head gathers oral cavity saliva, and spherical flocking swab head can diversely contact with saliva to wiping the sub-head and being circular, do not have any edges and corners, can not cause any loss to the oral cavity, the junction that wipes sub-pole and three-section swab pole in the middle section simultaneously is equipped with the easy portion of rolling over to the indent, can conveniently break, and can not have the condition of fish tail.

(2) The utility model relates to a specially adapted 96 orifice plates trace extraction instrument that draws adopts nylon fiber flocking technique preparation to form, and the front end scribbles the nylon short-staple fixed with the perpendicular mode for whole spherical flocking wipes the inside no absorption hole of son head collection area, and during the DNA cell can not disperse the fibre of detention, is favorable to more efficient elution sooner. The head of the spherical flocked swab is small, the spherical flocked swab head is inserted into a small hole of a 96-hole plate during use, the spherical flocked swab head can be broken off from the middle-section swab rod and the three-section swab rod slightly by force, the swab head is integrally retained in the small hole for subsequent operation, manual shearing is not needed, the operation is simple, the consumed time is short, meanwhile, the working efficiency can be greatly improved, the problem of cross contamination among samples is particularly avoided, and the detection accuracy is high.

(3) The utility model discloses the antislip strip of setting on handheld portion can prevent the phenomenon that the landing appears in the time of gathering the sample, and the security is higher.

Drawings

Fig. 1 is a schematic diagram of the system structure of the present invention.

In the drawings, the names of the parts corresponding to the reference numerals are as follows:

1-swab pipe sleeve, 2-arc piece, 3-handle, 4-wiper rod, 5-spherical flocking wiper head, 6-conical head wiper rod, 7-middle section wiper rod, 8-three section wiper rod, 9-sealing strip and 10-anti-slip strip.

Detailed Description

The present invention will be further described with reference to the following drawings and examples, and embodiments of the present invention include, but are not limited to, the following examples.

Examples

As shown in FIG. 1, a flocked swab with a spherical head DNA acquisition comprises a swab pipe sleeve 1 and a swab testing device sleeved with the swab pipe sleeve 1; the swab testing device comprises a handle 3 which is in contact with a swab pipe sleeve 1, a swab rod 4 with one end inserted into the handle 3, and a spherical flocked swab head 5 fixed on the top of the other end of the swab rod 4; the wiper rod 4 comprises a conical head wiper rod 6, a middle section wiper rod 7 and three sections of wiper rods 8 which are sequentially connected, wherein the conical head wiper rod 6 is connected with the spherical flocking wiper head 5, the three sections of wiper rods 8 are connected with the handle 3, an inward-concave easy-to-fold part 11 is arranged at the joint of the middle section wiper rod 7 and the three sections of wiper rods 8, and meanwhile, at least 3 arc pieces 2 which have the same trend as the three sections of wiper rods 8 and are used for reinforcing the three sections of wiper rods 8 are arranged on the three sections of wiper rods 8.
