Abstract
Description
Technical Field
[0001] The utility model relates to a medical device, in particular to a sputum suction tube sputum collection bottle. Background Art
[0002] Medical staff need to test the patient's sputum. The test results of the sputum can help understand the health of the patient's respiratory system, which is helpful for diagnosing and treating diseases. When doing sputum testing, the patient's sputum needs to be collected by an instrument. The existing sputum collection bottle generally includes a bottle body, which is connected to a soft suction tube and a sputum suction tube. The suction tube is connected to a negative pressure source, and the sputum suction tube is placed in the patient's mouth and nose. The patient's sputum is sucked into the bottle body through the sputum suction tube. If the suction force of the negative pressure source is too large, the sputum just sucked into the bottle body can easily enter the suction tube from the sputum suction tube, causing the suction tube to be blocked, or even causing damage to the instrument.
[0003] Therefore, how to design a sputum collection bottle that can prevent sputum from entering the suction tube has become an urgent problem to be solved in the field of medical devices. Utility Model Content
[0004] The utility model aims to provide a sputum collection bottle with a sputum suction tube, which can prevent the sputum in the bottle from entering the suction tube during negative pressure suction, so that the sputum collection can be carried out smoothly.
[0005] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:
[0006] A sputum suction tube sputum collection bottle comprises a transparent bottle body, a soft sputum suction tube and a soft air extraction tube, the bottle body is provided with a bottle mouth, the bottle mouth is covered with a top cover, the top cover is provided with a sputum suction port and an air extraction port, the fixed end of the sputum suction tube is fixed to the sputum suction port, the movable end of the sputum suction tube is placed in the patient's mouth and nose, the fixed end of the air extraction tube is fixed to the air extraction port, and the movable end of the air extraction tube is connected to a negative pressure source. A hard extension tube is provided at the lower end of the sputum suction port, the lower end of the extension tube extends vertically downward and away from the lower end of the air extraction port, and a blocking member is provided at the lower end of the extension tube for preventing sputum from entering the air extraction tube.
[0007] Compared with the prior art, the sputum collection bottle with a suction tube using the above technical solution has the following beneficial effects:
[0008] When using the sputum collection bottle with suction tube of the utility model, the medical staff puts the movable end of the suction tube into the patient's mouth and nose, and connects the movable end of the suction tube to the negative pressure source (negative pressure machine and central negative pressure device). During negative pressure suction, the suction tube draws air, so that the patient's sputum is sucked into the bottle body through the suction tube. Because the extension tube is pulled away from the lower end of the suction port, and the baffle can prevent the sputum sucked into the bottle body from floating toward the suction port, the suction tube is prevented from entering the suction tube, so that the sputum collection can be carried out smoothly.
[0009] Preferably, the baffle is a horizontally placed circular plate structure, the outer diameter of the baffle is slightly smaller than the inner diameter of the bottle body, and a plurality of through holes are provided on the surface of the baffle. The baffle has a better effect of blocking sputum. The through holes can enhance gas circulation, making it easier for sputum to be sucked into the bottle body.
[0010] Preferably, the outer diameter of the baffle gradually decreases from top to bottom, and the outer diameter of the upper end of the baffle is slightly smaller than the inner diameter of the bottle body, and the outer peripheral surface of the baffle is provided with a plurality of through holes for enhancing gas circulation. The through holes are arranged obliquely so that sputum is not easily blocked in the through holes. The outer peripheral surface of the baffle plays a transitional role, making it easier for the baffle to be placed in the bottle mouth. The through holes can enhance gas circulation and make it easier for sputum to be sucked into the bottle body.
[0011] Preferably, the sputum suction port and the extension tube are arranged at the center of the top cover, so that the extension tube is away from the inner circumference of the bottle body, so that sputum is not easy to stick to the inner circumference of the bottle body, and the lower end of the extension tube is avoided from being blocked.
[0012] Preferably, an elastic gasket is provided on the outside of the blocking piece, the gasket is made of silicone material, the outside of the gasket is closely fitted with the inner circumference of the bottle body, and the outside of the gasket is rounded. The gasket plays a buffering role to prevent the blocking piece from colliding with the inner circumference of the bottle body and causing damage; the rounded corners on the outside of the gasket play a transition role, making it easier to put the blocking piece into the bottle mouth.
[0013] Preferably, a horizontally placed filter screen is provided on the upper end surface of the blocking member. The filter screen can further enhance the blocking effect on sputum, prevent the sputum suction tube from entering the air extraction tube, and enable smooth sputum collection.
[0014] Preferably, the length of the extension tube is between 15 mm and 25 mm. The extension tube is far enough from the air suction port to prevent the sputum suction tube from entering the air suction tube.
[0015] Preferably, the utility model further comprises a bottom cover, which is threadedly connected to the bottom of the bottle body, and the top cover is threadedly connected to the bottle mouth of the bottle body, and the bottom cover can cover the bottle mouth of the bottle body. When the sputum is collected, the medical staff removes the top cover from the bottle mouth and discards it, then removes the bottom cover from the bottom of the bottle and covers the bottle mouth, and then sends it for testing, thereby reducing the space occupied by the collection bottle and making it convenient to carry.

The outer peripheral surface of the baffle 24 is provided with a plurality of through holes 25 for enhancing gas circulation. The through holes 25 are arranged obliquely so that sputum is not easily blocked in the through holes 25. The outer peripheral surface of the baffle 24 plays a transitional role, making it easier for the baffle 24 to be placed in the bottle mouth. The through holes 25 can enhance gas circulation and make it easier for sputum to be sucked into the bottle body 1.
[0038] refer to Figure 7 The upper end surface of the stopper 24 is provided with a horizontally placed filter screen 27.
