Abstract

The utility model provides a cell sampler, which is a medical device for collecting cell specimens from the oral cavity or other parts of the human body, comprising a brush head and a brush handle coupled to the brush head. The end surface of the brush head is provided with a plurality of strands of bristles forming a matrix-shaped three-dimensional brush bristle, and in particular, a stress-concentrating breaking notch is provided at a selected position of the brush handle. The breaking notch can be V-shaped and formed on one side, both sides or around the brush handle, thereby forming a cell sampler that can sample cell specimens by twisting the brush handle, and the excess brush handle can be broken off from the breaking notch, and then the part with the collected cell specimen is placed in a container, so as to facilitate the shipping and storage of the cell specimen.

Description

cell sampler

technical field

The utility model relates to a cell sampler.

Background technique

Physicians in general outpatient clinics or large-scale hospital outpatient clinics are not suitable for direct inspection, laboratory testing, and scientific analysis of patient samples. Physicians must use a sampler to collect cell samples from specific parts of patients, and then Transfer to laboratory or testing center for laboratory analysis. Known cell samplers have different shapes depending on the samples taken. One of them has a brush handle, and a brush head is formed at the end of the brush handle, and a row of soft bristles is arranged at the selected end of the brush head. In this way, the doctor can hold the brush handle, and then extend it into the oral cavity or vagina or other sampling sites, and the soft bristles reciprocate to pick up the selected site, so as to stick to the cell sample, and then transfer it to the laboratory for laboratory analysis.

The brush handle of the known sampler has a certain length, so that the soft bristles at the end of the brush head can penetrate into the oral cavity or vagina, but after the cell sample is collected, the too long brush handle becomes a cumbersome part, affecting the sealing of the sample. The convenience of procedures such as transfer and storage. Moreover, the bristles of the known sampler are in a single-row structure. During the operation, the cell specimen is stained by reciprocating brushing, but in the deep part of the oral cavity or vagina, it is difficult to perform the reciprocating brushing and sticking action.

Utility model content

In view of this, the main purpose of the present utility model is to provide a cell sampler which is convenient to use, operate, send and store.

According to the above purpose, the utility model cell sampler is made of brush handle, brush head and three-dimensional bristles, wherein: the brush handle is a rectangular or circular long rod, coupled at the selected end of the brush head, when the brush head is opposite to The end face of the brush handle is provided with three-dimensional bristles, and the three-dimensional bristles are combined in a matrix on the end face of the brush head in the form of several strands of bristles, and the brush handle is provided with a stress-concentrated fracture notch adjacent to the brush head, and the fracture notch can be The V-shaped breaking notch is formed on one side, both sides or around the brush handle.

It can be seen from the above technical solutions that the cell sampler of the present utility model allows doctors to directly hold the brush handle to carry out the twirling action of cell sampling, which avoids the reciprocating brush sticking action of known samplers and makes the cell sample sampling action more convenient conduct. Moreover, after the cell sampling is completed, the redundant brush handle can be quickly removed, so that the sampler can be reduced to an appropriate length that can be placed in the container, thereby achieving the effects of convenient operation, delivery and storage.

Detailed ways

The features and advantages of the utility model are described in detail below in conjunction with the accompanying drawings:

As shown in Figure 1, the cell sampler of the present utility model particularly refers to a cell sampler for medical use with three-dimensional bristles for taking cell samples, which is composed of a brush handle 1, a brush head 2 and three-dimensional bristles 3, wherein: The brush handle 1, as shown in Figure 1, can be a long rectangular rod, used as a holding part when operating the cell sampler, one end of the brush handle 1 is coupled to the selected end of the brush head 2, and the coupling method can be integrally formed The brush head 2 is a block for planting the three-dimensional bristles 3, which can be rectangular or other shapes, and is coupled with the aforementioned brush handle 1; the three-dimensional bristles 3 are made of soft hairs, and are planted on the brush head 2 Back to the end face of the brush handle 1.

And the improved design of the present utility model is: this three-dimensional bristle 3 is that several strands of hair bristles 31 are matrix-shaped and combined on the end face of the brush head 2, as shown in Figure 1, the bristles 31 can be arranged in four rows and four columns, but also It can be arranged in three rows and three columns; and a stress-concentrated breaking notch 4 is provided at a selected place adjacent to the brush head 2 of the brush handle 1, and the breaking notch 4 can be a V-shaped breaking notch formed on one side of the brush handle 1 . Or as shown in FIG. 2 , the breaking notch 4 may be a V-shaped breaking notch formed on two symmetrical sides of the brush handle 1 . Or as shown in FIG. 3 , the breaking notch 4 can also be a V-shaped breaking notch formed around a selected part of the brush handle 1 and is in the shape of an annular groove.

In addition, as shown in Figure 4, the brush handle 1 of the cell sampler of the present invention can also be in the shape of a circular long rod, and the V-shaped breaking gap is formed on one side of the brush handle 1 (as shown in Figure 4), or the corresponding Symmetrical two sides (as shown in Figure 5), or constitute around the selected place of the brush handle 1, and be in the shape of an annular groove (as shown in Figure 6), as for other structures such as the three-dimensional bristles 3, the same as the foregoing.

With the improved design of the structure of the above-mentioned cell sampler, when the doctor uses it to collect specimen cells, he can directly hold it on the brush handle 1, then extend it into the patient's mouth or vagina, and then hold the brush handle 1 for cell sampling The twirling action (as shown in Fig. 7 and Fig. 8), that is, twirling the brush handle 1 makes the end of the three-dimensional bristles 3 collect the cell specimen, exempting the reciprocating brushing action of the known sampler, and making the cell specimen The sampling action is more convenient to carry out.

And when the three-dimensional bristles 3 stick to the cell sample and are taken out, the excess brush handle 1 is broken and discarded in a labor-saving and rapid manner by utilizing the fracture stress concentration characteristics caused by the breaking gap 4 (as shown in Figure 9), and then Put the part of the brush head 2 and the three-dimensional bristles 3 into the container 5 and seal it (as shown in Figure 10 and Figure 11), so that the cell sample can be transferred to a laboratory or inspection center for laboratory analysis. It can be seen that the improved design of the utility model can not only effectively reduce the volume of the cell sampler, but also achieve the simplicity and convenience of operation and use due to the function of easy operation and easy breaking of the brush handle.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model.
