Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical appliances, in particular to a saliva sampling device. Background Art
[0002] Saliva is a colorless and thin liquid, commonly known as spit. When treating patients with oral diseases, dentists often need to sample and test oral saliva, which requires the use of corresponding saliva sampling devices.
[0003] In actual use, the existing oral saliva sampling device is often a simple cotton swab. When sampling, the staff holds the cotton swab and dips it into the saliva in the patient's mouth for sampling. However, the cotton swab is small and the amount of saliva dipped is small, which affects the accuracy of the subsequent saliva detection. At the same time, the cotton swab sampling is prone to contamination of the cotton swab by the fingers holding the hand and then contaminating the sampled saliva, which further affects the accuracy of the saliva detection. Therefore, we propose a saliva sampling device. Utility Model Content

[0006] By adopting the above technical solution, the handheld device inserts the connecting tube and the sphere deep into the oral cavity, so that the sphere fits the tongue coating, and then starts the liquid pump to generate negative pressure in the sampling tube, thereby generating negative pressure in the sphere, and then using the holes to absorb saliva, thereby introducing the saliva into the sampling tube, thereby achieving rapid sampling.
[0007] As a preferred embodiment of the present invention, a storage groove is formed at one end of the fixed shell close to the handle, and a cover plate is detachably fixed to the end of the fixed shell corresponding to the storage groove.
[0008] By adopting the above technical solution, the connecting tube can be disassembled and stored in the storage groove when not in use, and then the cover plate can be put on to protect the connecting tube and the ball, thereby preventing the ball and the connecting tube from being broken or damaged by impact when the device is not in use, thereby achieving a protective effect and extending the service life.
[0009] As a preferred embodiment of the present invention, the outer wall of the sampling tube is provided with scale lines.
[0010] By adopting the above technical solution, the sampling tube is a transparent plastic tube, so that when sampling, the sampling amount can be observed by referring to the scale line, thereby ensuring that the sampling amount is sufficient and improving the accuracy of sampling.
[0011] As a preferred embodiment of the utility model, the end cover and the sampling tube are engaged with each other through threads.
[0012] By adopting the above technical solution, the sampling tube can be easily disassembled, thereby facilitating the transfer of sampled saliva.
[0013] As a preferred embodiment of the present invention, a handle is fixedly mounted on one side of the bottom of the fixed shell.
[0014] By adopting the above technical solution and setting the handle, it is convenient to operate the device by holding the handle.
[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0016] The saliva sampling device of the technical solution of the present application is to place a hollow sphere in the oral cavity through a handheld device, and then start a liquid pump to generate negative pressure in the sampling tube, so that the hollow sphere generates negative pressure, so that saliva can be sucked into the sampling tube through the holes, so that rapid sampling can be achieved, and at the same time, sufficient sampling volume can be ensured, thereby ensuring the accuracy of subsequent detection, and the sampling volume can be accurately controlled by the scale line, so that the sampling volume is sufficient and the saliva overflowing and spilling when the sampling tube is removed due to excessive sampling can be avoided;
[0017] A storage groove is provided at one end of the fixed shell, so that the connecting tube and the ball can be disassembled and stored in the inner cavity of the storage groove when not in use, thereby avoiding the ball and the connecting tube from being impacted and broken when not in use, thereby achieving a protective effect.
