Problems solved by technology

The scraper is bulky, and its shape and material do not meet the physiological requirements of the human body, making it uncomfortable for patients to use
In addition, the amount of cells obtained is small, and the volume of the biological kit used due to the large volume also increases, so that more reagent solutions are used, resulting in waste of reagent solutions or increased costs
Due to the large amount of reagent solution, it takes a long time to culture the collected cells, which reduces the detection efficiency

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The living cell sampler of the present invention is composed of a sampler 1 , a slider 2 and a pull rod 3 , the slider 2 is sleeved on the pull rod 3 , and the insertion end 36 of the pull rod 3 is inserted into the cross groove 16a of the sampler 1 .

[0029] See Figure 1, image 3 As shown, the sampler 1 is integrally processed into a molded part, and is made of non-toxic polypropylene material; the sampler 1 is provided with A flexible wings 11, B flexible wings 12, and conical pillars 13; one end of the conical pillars 13 is a support head 15 , the other end of the tapered pillar 13 is a top 14, the end face of the top 14 is a circular surface, and the end face of the support head 15 is a plane; The size of the instrument when it enters the lesion site for sampling (see Figure 5). The outer plate surface of the A flexible wing 11 is provided with ...

Abstract

The invention discloses a living cell sampler that consists of a sampler, a slide block and a pull rod. The slide block is sheathed on the pull rod. The plug end of the pull rod is inserted into a cross slot arranged in the sampler. The sampler is an integrated machine-shaped component. The sampler is provided with an A flex-wing, a B flex-wing and a tapered strut. One end of the tapered strut is provided with a support head and the other end of the tapered strut is a top head. The head face of the top head is a circular face and the head face of the support head is a flat face. The outer surface of the A flex-wing is provided with an A convex pellet and the outer surface of the B flex-wing is provided with a B convex pellet. The living cell sampler provided by the invention adopts the design of flexible structure that meets the physiological requirements of the human body and facilitates the collection of the living cell tissue in a lesion. The combination of a sampling head of the flexible structure and a small-size sampling head can downsize the bottle mouth and the bottle body of a biological reagent box, reduce the usage of biological reagent and enlarge the application range of the living cell sampler.

Description

technical field [0001] The present invention relates to a medical device, more particularly, to a living cell sampler capable of shrinking and expanding and capable of separating the sampler. Background technique [0002] When hospitals carry out live cell sampling to lesion sites, most of them currently use scrapers made of bamboo or wood to carry out live cell sampling. The scraper is bulky, and its shape and material do not meet the physiological requirements of the human body, making it uncomfortable for patients to use. In addition, the amount of cells obtained is small, and the volume of the biological kit used due to its large volume also increases accordingly, so that more reagent solutions are used, resulting in waste of reagent solutions or increased costs. Due to the large amount of reagent solution, the culture time for the collected cells is also long, which reduces the detection efficiency. Contents of the invention [0003] The purpose of the present inven...
