Description
Technical Field
The utility model relates to the technical field of laboratory equipment, in particular to a cell brush for brushing cells from a nasal basal layer by using a macromolecular reticulum compound.
Background
Currently, in clinical diagnosis and treatment of respiratory diseases, in order to more accurately and clearly understand the cause of the disease and thus to make a better treatment plan, it is often necessary to access a patient's nose through a device to obtain tissue, cells or other samples, and then further analyze the extracted samples to determine the disease. At present, the device for brushing the sample from the nasal cavity is commonly a nose swab and a hairy cell brush, but due to the influence of factors such as the structures of the nose swab and the hairy cell brush, flocculent substances on the nose swab and the hairy substances on the hairy cell brush easily cause sample pollution in the sample brushing and separating process, so that later analysis is interfered, diagnosis is inaccurate, and treatment of a patient is influenced.
Disclosure of Invention
The utility model aims to solve the technical problems that the existing equipment for brushing samples from nasal cavities is commonly a nose swab and a hairy cell brush, but flocculent substances on the nose swab and hairy substances on the hairy cell brush are easy to pollute the samples in the process of brushing and separating the samples due to the influence of factors such as the structures of the nose swab and the hairy cell brush, so that the later analysis is interfered, the diagnosis is inaccurate, and the treatment of patients is influenced.
In order to solve the technical problems, the utility model adopts the following technical means:
a cell brush for brushing cells from a nasal basal layer by using a macromolecule reticular compound, which comprises a tube body and a brush head; the brush head include guide head and cytobrush, the body include inner tube and outer tube, inner tube one end connect the cytobrush, the inner tube other end is equipped with the pull ring, is equipped with the cavity in the outer tube, the outer tube outside is equipped with fixing device, the guide head set up at the cytobrush top, fixing device be the buckle, the buckle is used for fixing the position of inner tube in the outer tube.
Preferably, the utility model further adopts the technical scheme that:
the inner tube can move left and right in the outer tube cavity under the action of the pull ring.
The cell brush is of a grid structure, and is made of high polymer compound rubber.
The front end of the guide head is arc-shaped, the rear end of the guide head is conical cylindrical, and the cross section size of the guide head is smaller than that of the inner pipe.
The inner tube can be selected to be suitable according to the actual demands of the nasal cavity lengths of people of different ages.
The length of the outer tube is matched with that of the inner tube, and the inner tube can be fully stretched into the cavity of the outer tube.
The pull ring is provided with an anti-slip rubber sleeve.
The inner wall of the outer tube and the outer wall of the inner tube are provided with nano sterilizing coatings
According to the cell brush for brushing cells from the nasal basal layer by using the high-molecular reticular compound, when the cell brush prepared from the reticular compound is used for brushing cells from the nasal basal layer, skin and tissues are not damaged during sampling due to soft texture, the density is high, and impurities are not easy to fall off to cause sample pollution during sample separation, so that the whole device has a simple structure and is convenient to operate.

Fig. 1 is a schematic structural diagram of an embodiment of the present utility model.
Reference numerals illustrate: 1-a guide head; 2-cell brushing; 3-an inner tube; 4-an outer tube; 5-clamping buckles; 6-pull ring.
Detailed Description
The utility model will be further illustrated with reference to the following examples.
Referring to fig. 1, the product of the utility model is a cell brush for brushing cells from the basal layer of the nose by using a polymer network compound, and can brush cells from the basal layer of the nose conveniently and rapidly. The product structure is shown as the figure and comprises six parts of a guide head 1, a cell brush 2, an inner tube 3, an outer tube 4, a buckle 5 and a pull ring 6. The cell brush 2 is a latticed cell brush made of a high polymer compound, has the advantages of soft texture, no damage to skin and tissues during sampling, high density, no pollution to samples caused by sundries falling off easily during sample separation, and the like, one end of the cell brush is connected with the guide head 1, buffering is given during sampling of a nasal basal layer, damage to tissues in the nasal cavity caused by excessive force is prevented, the end face of the front end of the guide head 1 is arc-shaped, the rear end of the guide head is conical and the cross section size of the guide head is smaller than that of an inner tube; the other end of the inner tube is connected with the inner tube 3, the tail end of the inner tube is provided with a pull ring 6, the inner tube 3 is slidably arranged in the outer tube 4 in a penetrating way under the action of the pull ring 6, and the inner tube can select proper length according to the actual requirements of the nasal cavity lengths of people of different ages; the catch 5 is used to fix the position of the inner tube in the outer tube.
Referring to fig. 1, the cell brush of the present utility model is prepared by brushing cells from a nasal basal layer by using a polymer network compound, and the method of using the cell brush comprises:
the right hand outer tube is inserted into the nasal cavity base of the person to be sampled, the insertion is stopped after the guide head touches the nasal cavity, the left hand ring is pulled to adjust the inner tube to a proper length, meanwhile, the right hand thumb presses the buckle to fix the length of the inner tube, and the nasal brush is gently rotated for a plurality of times, so that the sampling is completed.
Since the above description is only specific embodiments of the present utility model, the protection of the present utility model is not limited thereto, and any equivalent changes or substitutions of technical features of the present utility model will be apparent to those skilled in the art, and are included in the scope of the present utility model.
