Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical auxiliary device technology, specifically a sampling device for clinical use. Background Technology
[0002] Patients with digestive diseases often experience repeated vomiting and weakness. During treatment, medical staff need to take samples from the patient's vomit for testing. The hospital will place a trash can next to the patient's bed. The patient vomits into the trash can, and the medical staff have to take samples from it. Since the trash cans are open, the odor from the vomit is difficult to deal with. Therefore, the medical staff have to endure the odor while taking samples, which is very painful. If the trash can is not emptied quickly, the odor can easily spread into the ward, making it unbearable for the patient as well. Summary of the Invention
[0003] To avoid medical staff directly taking samples from patients' vomit, this invention provides a sampling device for clinical use, which can be conveniently used by patients with digestive diseases to collect their vomit, while medical staff can complete the sampling work without direct contact with the patient's vomit.
[0004] The technical solution is as follows: A sampling device for clinical use, comprising:
[0005] The upper barrel has a lid on top, a feeding plate in the middle, and a material collection bin below the feeding plate.
[0006] The lower barrel is located at the lower end of the upper barrel, and a sampling component is installed inside it. A rotatable arc-shaped door is installed at the front.
[0007] The sampling assembly includes a receiving pipe, a piston pipe, a discharge pipe, and a sampling pipe. The bottom of the silo is provided with a discharge pipe, and the receiving pipe is connected to the discharge pipe. The piston pipe is horizontally arranged at the lower part of the receiving pipe, and the discharge pipe is vertically arranged at the lower part of the piston pipe, with the discharge pipe aligned with the receiving pipe. The sampling pipe is arranged on the left side of the piston pipe, and a piston rod is slidably installed on the right side. The sampling pipe is bent upward to form an arch shape, and the end is bent downward and connected to a sampling bottle.
[0008] As a preferred embodiment of this utility model, the feeding sheet is a concave triangular plastic sheet that is elastic, and multiple feeding sheets are arranged in a circle and fixed to the inner wall of the upper barrel by bolts.
[0009] As a preferred embodiment of this utility model, the bottom of the material hopper is a circular concave surface, and the discharge pipe is located at the center.
[0010] As a preferred embodiment of this utility model, a pipe valve is provided at the connection between the piston tube and the discharge tube.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to limit the specific scope of the invention.
[0024] See Figures 1 to 5 The present invention provides a sampling device for clinical use, comprising:
[0025] The upper barrel 1 has a barrel cover 13 on the top, a material feed plate 11 installed in the middle, and a material accumulation bin 12 below the material feed plate 11.
[0026] The lower barrel 2 is located at the lower end of the upper barrel 1, and is equipped with a sampling component 3 inside. A rotatable arc-shaped door 21 is installed at the front.
[0027] The sampling assembly 3 includes a receiving pipe 31, a piston pipe 32, a discharge pipe 33, and a sampling pipe 34. The bottom of the silo 12 is provided with a discharge pipe 121, and the receiving pipe 31 is connected to the discharge pipe 121. The piston pipe 32 is arranged horizontally at the lower part of the receiving pipe 31, and the discharge pipe 33 is arranged vertically at the lower part of the piston pipe 32. The discharge pipe 33 is aligned with the receiving pipe 31. The sampling pipe 34 is arranged on the left side of the piston pipe 32, and a piston rod 321 is slidably installed on the right side. The sampling pipe 34 is bent upward to form an arch shape, and the end is bent downward and connected to a sampling bottle 35.
[0028] It should be noted that, for reference Figure 2 , Figure 3 As shown, when a patient vomits into the upper container 1, the vomit flows from the gap in the discharge plate into the collection bin 12 for storage. The vomit at the bottom flows from the discharge pipe 121 into the piston tube 32. If medical staff need to take a sample, they first push the piston rod 321. The piston rod 321 moves from right to left, pushing the vomit in the piston tube 32 to the left. Then, it flows through the bend in the sampling tube 34 into the sampling bottle 35. When a suitable amount of sample has been collected, the piston rod 321 is pulled back, so that the vomit stops flowing and continues to be stored in the piston tube 32. The medical staff then remove the sampling bottle 35 for testing, thus completing the entire sampling process.
[0029] In this embodiment, the feed piece 11 is a concave triangular plastic sheet with elasticity. Multiple feed pieces 11 are arranged in a circle and fixed to the inner wall of the upper barrel 1 by bolts.
[0030] It should be noted that, for reference Figure 5 As shown, the feeding sheet 11 is made of elastic plastic. There is a gap between each feeding sheet 11. After the vomit falls, the feeding sheet 11 is pressed down, making the gap larger. In this way, the vomit will fall from the gap into the collection bin 12. Then the feeding sheet 11 returns to the initial position, and the gap becomes smaller. The odor is also sealed in the collection bin 12, preventing the odor from spreading into the room.
[0031] In this embodiment, the bottom of the material hopper 12 is a circular concave surface, and the material discharge pipe 121 is located at the center.
[0032] In this embodiment, a pipe valve 331 is provided at the connection between the piston tube 32 and the discharge tube 33.
[0033] In this embodiment, the sampling tube 34 has a vertically upward-facing drain pipe 341 connected to the arched part. The upper barrel 1 has a water inlet pipe 14 on its side and its bottom is connected to the drain pipe 341. The material feed plate 11 and the barrel cover 13 have a protruding block 15 in the middle position. The protruding block 15 has an annular water channel 151 inside. The bottom of the water channel 15 has evenly distributed water outlets 152 aligned with the material feed plate 11. At the same time, an inclined water delivery pipe 141 is provided between the water channel 151 and the water inlet pipe 14.
[0034] It should be noted that, for reference Figure 3 , Figure 4 As shown, the inlet pipe 14 of this device is used to clean the inside of the device. Water flows from the water supply pipe 141 into the water channel 151 and then out from the outlet 152, rinsing the inside of the device from top to bottom. At the same time, some water flows from the drain pipe 341 into the sampling pipe 34 and the piston pipe 32 to rinse away any foreign matter remaining in the pipes, ensuring the cleanliness and hygiene of the device. Therefore, when using the device, the water pipe is aligned with the inlet pipe 14. Part of the water flows from the water supply pipe to the upper part of the upper tank 1, rinsing away foreign matter inside the device from top to bottom. The other part of the water directly enters the sampling component 3 to flush the various pipes inside the device and remove all vomit from the pipes. This allows for a thorough cleaning of the entire device, making it convenient for subsequent use.
