In the figure, 1, a brush rod; 11. a tube hole; 2. a liquid storage head; 3. a brush head; 31. brushing; 32. a brush seat.

The following detailed description of the invention will be further described in conjunction with the above-identified drawings.

Detailed Description

Referring to fig. 1, 2, 3 and 4, in a preferred embodiment of the present invention,

example 1

As shown in figure 1, the novel brush for the fecal smear comprises a brush head, a brush rod and a liquid storage head, wherein the brush head is composed of brush hairs and a brush base, the brush hairs are connected with the brush base in a hot melting or gluing mode, and the length of the brush hairs at the working end of the brush hairs is consistent and parallel. The liquid storage head of the hairbrush is an ellipsoidal hollow sphere, the liquid storage head is made of soft rubber, the soft rubber is soft silica gel, the silica gel is made into a hollow ellipsoidal shape, the texture of the silica gel is soft, and the liquid storage head can naturally rebound to an original shape after being extruded by external force; and the maximum diameter of the liquid storage head perpendicular to the length direction of the brush rod is not more than twice of the maximum size of the cross section of the brush rod. A plurality of hollow pipe channels are arranged in the brush rod along the length direction of the brush rod, one end of the brush rod is connected with the liquid storage head, and the hollow pipe channels of the brush rod are communicated with the interior of the liquid storage head; the brush head is fixedly connected with the other end of the brush rod through the brush seat, and the direction of the bristles is the length direction of the brush rod; the hollow pipe channel of the brush rod of the utility model has an inner diameter not larger than 0.3 mm. In the operation process, the liquid storage head can be extruded to extrude the physiological saline out to enter the brush hair position of the brush head through the hollow tube channel of the brush rod and to be dripped on the detected glass slide.

Referring to fig. 1, 3 and 4, in order to achieve the above-mentioned functions, the brush base of the present invention is made of porous material, the brush base can be made of porous ceramic, the physiological saline can enter the brush base through the brush rod, and the physiological saline further drops down along the bristles after the bristles connected to the brush base are wetted. The liquid storage head is not more than twice the maximum size of the cross section of the brush rod along the maximum diameter of the length direction of the vertical brush rod.

Referring to fig. 3, the bristles of the present invention are made of short plastic threads; the maximum size of the cross section of each bristle is not more than 0.1 mm; and the brush hair length of the work end of brush hair is unanimous and parallel and level, conveniently after the sample with even the smearing on the slide of excrement and urine sample.

Referring to fig. 3, based on the embodiment 1, the brush holder can be made of sponge, and the bristles are fixedly connected with the sponge brush holder, the connection mode can be a hot pressing or bonding mode, and the bristles are not separated from the sponge after being soaked in physiological saline, the physiological saline can enter the brush holder through the brush rod, and after the bristles connected with the brush holder are wetted, the physiological saline further drops along the bristles.

Further, single cross section maximum dimension of brush hair is no longer than 0.1mm, and the oversize brush hair is too hard easily, and the brush hair parallel and level, can be more even during the brush appearance.

Further preferably, in embodiment 1, the liquid storage head may be made of soft plastic, and the soft plastic is PP plastic; the thickness of the PP plastic is 0.5-1.0 mm, so that the PP plastic is ensured to have sufficient elasticity; the liquid storage head can naturally rebound to the original shape after being extruded by external force.

When the normal saline is stored, the liquid storage head can be emptied and extruded until no space exists, then the brush head is immersed into the normal saline to release the extrusion external force of the liquid storage head, the normal saline is immersed into the liquid storage head along the hollow pipe channel of the brush rod, if the liquid storage head cannot be filled with the normal saline, the empty space of the liquid storage head can be emptied and the actions can be repeated, and the effect that the liquid storage head is full of the normal saline is achieved.

Use the utility model discloses during the brush, can be used for getting excrement and urine sample with the brush head of brush earlier, then extrude the stock solution head again, make normal saline pass through hollow tube passageway and get into the brush head, drip on the slide glass, smear on the slide glass with the brush hair simultaneously.

The above description is for the detailed description of the preferred possible embodiments of the present invention, but the embodiments are not intended to limit the scope of the present invention, and all equivalent changes or modifications accomplished under the technical spirit suggested by the present invention should fall within the scope of the present invention.
