Embodiment Construction

[0008] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0009] Such as figure 1 As shown, the digestive tract mucosal biopsy sampling device includes a sample extraction part 1 and a handle 2. The sample extraction part 1 is set as a middle drum and a long rubber strip with two pointed ends. The outer surface of the rubber strip is distributed with many small The spatula 11, the sample extraction part 1 is connected to the handle 2, the handle 2 is set as a rotating shaft driven by a motor, and the handle 2 is provided with a switch 21.

[0010] When in use, insert the sample extraction part 1 into a suitable position inside the upper airway of the patient, press the switch 21, the handle 2 starts to rotate, rotate quickly for one circle, and the sampling ends. The whole process ends before the patient has time to respond, avoiding the manual sampling process Slowly, the patient is prone to vomiting and oth...

Abstract

The invention discloses a digestive tract mucosa biopsy sampling device, and relates to the field of medical appliances. The digestive tract mucosa biopsy sampling device comprises a sample extraction component and a handle, wherein the sample extraction component is made into a long rubber strip with the projected middle part and the two pointed ends; a plurality of tiny scraping spoons are distributed on the outer surface of the rubber strip; the sample extraction component is connected with the handle; the handle is made into a rotating shaft driven to rotate by a motor; a switch is arranged on the handle. The long rubber strip with the projected middle part and the two pointed ends is designed and used as a main body for extracting a sample; the scraping spoons are arranged on the outer surface; the sample extraction is more convenient; the quantity of extracted samples is great; injury cannot be caused on the respiratory tract of a patient; the rotatable handle is designed; the sample extraction process is completed after a switch is turned on and is fast rotated for one circle; the pain of the patient and the workload of medical care personnel are reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a respiratory mucosal biopsy sampling device. Background technique [0002] Clinically, upper gastrointestinal mucosal biopsy is the most effective method for diagnosing upper gastrointestinal diseases. The upper gastrointestinal biopsy sampling device currently used is mainly composed of metal balls and scrapers. Scraping the mucous membrane of the alimentary canal seriously damages the alimentary tract, and it is easy to cause swallowing or vomiting, which brings great pain to the patient. At present, there is also the practice of using air bags instead of metal balls, and there is also the practice of wrapping tampons on the outer surface of the metal balls, so as to reduce the damage to the digestive tract. However, there are many unstable factors in the manual operation handle, the operation is slow, and it is easy to cause unnecessary injury to the patient. Contents of the...
