Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a simple sputum suction device. Background Technology

[0002] Sputum is a secretion from the human respiratory tract. It is coughed up from the trachea and expelled from the body through a normal cough reflex. Normal people produce very little sputum, just a small amount of mucus secreted to keep the respiratory tract moist. However, when a person inhales irritating gases, dust, pathogenic bacteria, viruses, or other harmful microorganisms, inflammation of the upper respiratory tract may occur, or lung disease may develop. This will increase respiratory secretions, increase the amount of sputum, and change the nature of the sputum. Elderly patients, due to their physical function, are sometimes unable to cough up sputum, especially those who are bedridden for a long time. They are prone to lung infections, which can then lead to systemic infection symptoms.

[0003] Currently, most existing sputum suction devices use a threaded connection to install the sputum collection bottle, directly connecting it to the suction tube. Since the collection bottle lacks a top cap, the sputum inside is easily exposed to the outside after disassembly, causing sample contamination. Furthermore, the odor emitted by the sputum can pollute the surrounding environment. Therefore, we propose a simplified sputum suction device. Utility Model Content

[0004] The purpose of this invention is to provide a simple suction device to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simple suction device, comprising a suction tube, a connecting sleeve, and an extension tube. One end of the suction tube has a suction hole on its outer periphery. The end of the suction tube away from the suction hole has a guide tube. The bottom of the guide tube has a connecting sleeve. The bottom end of the connecting sleeve has an installation groove. The installation groove has an extension tube inside, with its top communicating with the inside of the guide tube. The top wall of the installation groove has slots on both sides. The installation groove has a collection bottle inside, with a bottle cap threaded to its top. The top of the bottle cap has insert plates with locking blocks fixedly installed on both sides. The bottle cap has a through hole at its center, with a flap at the bottom of the through hole. One side of the flap is movably connected to the bottle cap via a connecting shaft. Both ends of the connecting shaft are provided with torsion springs.

[0006] Preferably, push blocks are slidably connected to both sides of the outer bottom end of the connecting sleeve, and one end of the push block extends into the inside of the slot and is slidably connected to its inner wall.

[0007] Preferably, a return spring is provided on both sides of the push block, and the two ends of the return spring are fixedly connected to the push block and the connecting sleeve, respectively.

[0008] Preferably, the insert plate is provided with a snap-fit ​​spring inside, and the two ends of the snap-fit ​​spring are fixedly connected to the insert plate and the snap-fit ​​block, respectively.

[0009] Preferably, a sealing gasket is fixedly provided on the inner top wall of the mounting groove by adhesive bonding, and a sealing groove is provided on the top surface of the bottle cap corresponding to the position of the sealing gasket.

[0010] Preferably, the end of the guide tube away from the suction tube is provided with a suction tube, and the end of the suction tube is sealed and connected to the negative pressure device.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The collection bottle is installed using a plug-in and snap-fit ​​method, allowing it to be installed into the mounting slot along with the bottle cap. An extension tube extends into the collection bottle to ensure sputum collection. In conjunction with a flap with a torsion spring, the flap is automatically opened by the extension tube during installation and automatically closed by the torsion spring during disassembly, thus ensuring the stability of the sputum sample and avoiding contamination and external pollution.

[0013] 2. By setting a pusher with a reset spring and extending it into the slot, the function of pushing the block to retract is realized, thereby achieving the purpose of releasing the jamming, so as to facilitate quick disassembly of the collection bottle and convenient handling of the collection bottle.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a simple suction device: it includes a suction tube 1, a connecting sleeve 5, and an extension tube 7. A suction hole 2 is provided on the outer periphery of one end of the suction tube 1. A guide tube 3 is provided on the end of the suction tube 1 away from the suction hole 2. A connecting sleeve 5 is provided at the bottom of the guide tube 3. An installation groove 6 is provided inside the bottom end of the connecting sleeve 5. An extension tube 7 is provided inside the installation groove 6. The top of the extension tube 7 is connected to the inside of the guide tube 3. A slot 9 is provided on both sides of the top wall inside the installation groove 6. A collection bottle 12 is provided inside the installation groove 6. A bottle cap 13 is threaded to the top of the collection bottle 12. Insert plates 17 with locking blocks 18 are fixedly installed on both sides of the top of the bottle cap 13. A through hole 14 is provided at the center of the bottle cap 13. A flap 15 is provided at the bottom of the through hole 14. One side of the flap 15 is movably connected to the bottle cap 13 through a connecting shaft. Torsion springs 16 are provided at both ends of the connecting shaft.

[0020] Specifically, push blocks 10 are slidably connected to both sides of the outer bottom end of the connecting sleeve 5. One end of the push block 10 extends into the inside of the slot 9 and is slidably connected to its inner wall.

[0021] Specifically, the push block 10 is provided with a return spring 11 on both sides, and the two ends of the return spring 11 are fixedly connected to the push block 10 and the connecting sleeve 5 respectively.

[0022] Specifically, the insert plate 17 is equipped with a snap-fit ​​spring 19 inside, and the two ends of the snap-fit ​​spring 19 are fixedly connected to the insert plate 17 and the snap-fit ​​block 18 respectively.

[0023] Specifically, a sealing gasket 8 is fixedly installed on the inner top wall of the mounting groove 6 by adhesive bonding, and a sealing groove 20 is opened on the top surface of the bottle cap 13 corresponding to the position of the sealing gasket 8.

[0024] Specifically, the end of the drainage tube 3 away from the suction tube 1 is provided with a suction tube 4, and the end of the suction tube 4 is sealed and connected to the negative pressure device.
