Description

Technical Field

[0001] This utility model relates to the field of suction device technology, and in particular to a handheld rechargeable suction device. Background Technology

[0002] A suction device is a medical device used to clear respiratory secretions. It is primarily used for routine suctioning of sputum and tracheotomy in wounded and sick personnel. It is suitable for military combat medical care and for timely suctioning of sputum in hospitals or homes when there is respiratory mucus or vomit. Common types of suction devices are mainly divided into electric and manual suction devices. Electric suction devices have both a power switch and a manual control switch, utilizing negative pressure for suctioning and oral care; they are simple and easy to learn. Manual suction devices can be used for suctioning and emergency treatment during transport and in the field. They are characterized by no power supply required, small size, light weight, strong suction, compact structure, portability, low cost, and durability.

[0003] Traditional electric suction devices require a power cord, limiting their application to environments with electricity. While existing technologies, such as the portable rechargeable suction device for intensive care (CN214911333U) and the miniature portable electric suction device with a replaceable sputum container (CN220344812U), have independent power supplies, solving the limitation of traditional electric suction devices, the soft suction tubes of these devices require both hands from healthcare professionals to insert into the patient's throat. This is unsuitable for severely ill patients who cannot open their mouths during transport, as healthcare professionals must manually pry open the patient's jaw with one hand to keep their mouth open. This makes the two-handed operation of these suction devices inconvenient. Utility Model Content

[0004] To address the problem mentioned in the background art that existing suction devices require two hands to operate and are inconvenient to use, this utility model provides the following technical solution:

[0005] A handheld rechargeable suction device includes a housing, a handle for easy handholding fixed to one side of the bottom of the housing, and a base on the outside of the handle, the top of which contacts the bottom of the housing.

[0006] One end of the housing is provided with a suction tube for suctioning phlegm, and one end of the suction tube is connected to a suction component for assisting the insertion of the suction tube into the human throat.

[0007] The suction assembly includes a rigid tube a installed at one end of the housing, the rigid tube a being sleeved on the outer end of the suction tube, one end of the rigid tube a penetrating the housing and extending into the housing, one end of the suction tube being connected to a rigid tube b, one end of the rigid tube b being inserted into the rigid tube a, the other end of the rigid tube b being connected to a retractable corrugated tube, one end of the corrugated tube being connected to a miniature negative pressure pump for suctioning gas inside the suction tube.

[0008] The bottom of the rigid tube b is provided with a push-pull mechanism for pulling the rigid tube a into the housing and pushing the rigid tube b toward the suction tube, and then the moving rigid tube b pushes the suction tube into the human throat.

[0012] Furthermore, a rotating shaft is fixedly inserted through the gear, and both ends of the rotating shaft are movably connected to the inner wall of the housing via bearings.

[0013] Furthermore, the suction tube includes a bulb and a tubing, the bulb being connected to the tubing, and the surface of the bulb having multiple through holes.

[0014] Furthermore, guide blocks are fixed to the front and rear sides of one end of the rigid tube a inserted into the housing. A round rod passes through the guide block, and the guide block slides along the outer wall of the round rod. Fixing plates are fixed to both ends of the round rod, and the fixing plates are fixed to the inner wall of the housing.

[0015] Furthermore, a battery for powering the miniature negative pressure pump is installed inside the housing, and a Type-C charging port for charging the battery is installed on one side wall of the housing.

[0016] Furthermore, a micro controller for displaying the suction power of the micro negative pressure pump is embedded in one end of the housing. The micro controller has a built-in display screen and is powered by a battery. The micro controller is located on top of the Type-C charging port. Multiple buttons are provided between the micro controller and the Type-C charging port. One button controls the power switch, one button increases the suction power of the micro negative pressure pump, and one button decreases the suction power of the micro negative pressure pump.

[0017] Furthermore, the outlet at the top of the miniature negative pressure pump is connected to a sputum storage container, and a sputum storage container mounting base is fixed to the top of the housing. The sputum storage container is inserted into the sputum storage container mounting base and fixed to the top of the housing by the sputum storage container mounting base.

[0035] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0036] Please see Figure 1 This utility model provides a handheld rechargeable sputum suction device, including a housing 1, a handle 2 for easy handholding fixed to one side of the bottom of the housing 1, and a suction tube 3 for suctioning sputum provided at one end of the housing 1. The specific structure of the suction tube 3 is as follows: Figure 2-5 As shown, it includes a ball head 31 and a flexible tube 32. The ball head 31 is connected to the flexible tube 32. The surface of the ball head 31 has multiple through holes. Phlegm in the human throat can enter the interior of the flexible tube 32 through the through holes on the ball head 31. Moreover, the through holes are located at different positions on the ball head 31, which can facilitate the suction of phlegm from multiple directions.

[0037] A suction component 4 is connected to one end of the suction tube 3 to assist in insertion of the suction tube 3 into the human larynx. Specifically, as shown in the figure... Figure 2-5 As shown, the suction assembly 4 includes a rigid tube a41 installed at one end of the housing 1. The rigid tube a41 is sleeved on the outer end of the flexible tube 32. One end of the rigid tube a41 penetrates the housing 1 and extends into the interior of the housing 1, allowing the rigid tube a41 to move back and forth inside the housing 1. When in use, the rigid tube a41 is sleeved on the outer end of the flexible tube 32 to increase the rigidity of the flexible tube 32 from the outside. Compared with the traditional method of directly inserting the soft flexible tube 32 into the mouth, which causes the flexible tube 32 to bend, this utility model can prevent the flexible tube 32 from bending during insertion by sleeved with a rigid tube a41 on the outside of the flexible tube 32, so as to facilitate one-handed operation by medical staff.

[0038] like Figure 2 and 3When the flexible tube 32 shown is fitted with a rigid tube a41 at its outer end, the ball head 31 can only be inserted into the human mouth due to the restriction of the rigid tube a41. If the ball head 31 is to be inserted into the human throat, the rigid tube a41 needs to be pulled into the housing 1, and the ball head 31 needs to be pushed towards the human throat. To achieve this effect, this utility model has a rigid tube b42 connected to one end of the flexible tube 32. One end of the rigid tube b42 is inserted into the rigid tube a41, and the other end of the rigid tube b42 is connected to a retractable corrugated tube 43. One end of the corrugated tube 43 is connected to a suction device. A miniature negative pressure pump 44 is used to pump gas inside the ball head 31 and the hose 32. The outlet of the miniature negative pressure pump 44 is connected to a sputum storage container 5. A sputum storage container fixing seat 410 is fixed to the top of the housing 1. The sputum storage container 5 is inserted into the sputum storage container fixing seat 410 and fixed to the top of the housing 1 by the sputum storage container fixing seat 410. By starting the miniature negative pressure pump 44, the miniature negative pressure pump 44 draws gas from the corrugated tube 43, the rigid tube b42 and the ball head 31, thereby sucking the sputum stuck in the human throat into the sputum storage container 5.

[0039] In this embodiment, the sputum collection container 5 is a disposable consumable made of medical plastic materials such as polyethylene and polypropylene. It is lightweight and easy to process. After each use, the sputum collection container 5 can be directly removed and replaced, which can also avoid cross-infection, ensure hygiene, and improve safety.

[0040] Furthermore, the suction power of the miniature negative pressure pump 44 in this invention is adjustable. A battery 47 for powering the miniature negative pressure pump 44 is installed inside the housing 1. A Type-C charging port 48 for charging the battery 47 is installed on one side wall of the housing 1. A miniature controller 46 for displaying the suction power of the miniature negative pressure pump 44 is embedded at one end of the housing 1. The miniature controller 46 has a built-in display screen and is powered by the battery 47. The miniature controller 46 is located on top of the Type-C charging port 48. Multiple buttons 49 are provided between the miniature controller 46 and the Type-C charging port 48, one of which controls the power switch, and another... Button 49 is used to increase the suction of the miniature negative pressure pump 44, and button 49 is used to decrease the suction of the miniature negative pressure pump 44. The remaining power of the battery 47 can be displayed on the screen of the micro controller 46. When the battery 47 is low on power, it can be charged through the Type-C charging port 48, making the present invention reusable. Moreover, medical staff can adjust the suction of the miniature negative pressure pump 44 by pressing button 49. For young children, the suction can be adjusted to 80-100 mmHg, and for adults, the suction can be adjusted to 80-120 mmHg. The specific value can be adjusted according to the patient's specific condition during use to ensure the suction effect.

[0041] Furthermore, such as Figure 4 and 5 As shown, a push-pull mechanism 45 is provided at the bottom of the rigid tube b42 for pulling the rigid tube a41 into the housing 1 and pushing the rigid tube b42 toward the suction tube 3. The moving rigid tube b42 then pushes the ball head 31 and the first section of the flexible tube 32 into the human throat. The specific structure of the push-pull mechanism 45 is as follows: Figure 6 As shown, the device includes a rack a451 fixed to the bottom of a rigid tube a41. A gear 452 meshes with the bottom end of the rack a451. A rotating shaft 453 is fixed through the gear 452. Both ends of the rotating shaft 453 are movably connected to the inner wall of the housing 1 via bearings. A rack b454 meshes with the bottom of the gear 452. The rack b454 is slidably installed in the inner wall of the housing 1. A ring-shaped bracket 456 is fixed to the end of the rack b454 away from the gear 452. The ring-shaped bracket 456 is fixed to the outer wall of the rigid tube b42. A bracket 455 is fixed to one side of the bottom of the ring-shaped bracket 456. A spring 457 is fixed to one side of the bracket 455. A limit block 458 is fixed to the bottom end of the bracket 455. The limit block 458 is located at the top front side of the handle 2, and a groove 459 for the limit block 458 to slide is provided at the bottom of the housing 1.

[0042] In use, medical staff hold the handle 2 with one hand, and then press the limiting block 458 with their index finger to fix it in place. Figure 5 and 6 As shown, the spring 457 is in a stretched state. After the medical staff inserts the ball head 31 into the mouth, they can release their index finger. The stretched spring 457 can then pull the support 455, the ring support 456, and the rigid tube b42 towards the ball head 31. As the rigid tube b42 moves, it pushes the ball head 31 deeper into the throat. Then, by pressing the button 49 to start the micro negative pressure pump 44 with the thumb, the micro negative pressure pump 44 can be activated. The micro negative pressure pump 44 is used to suction the sputum stuck in the throat. Compared with traditional suction devices, medical staff can operate it with one hand, which is convenient for use during patient transport. The suction force can be precisely controlled, which can also ensure the suction effect.

[0043] At the same time, the bracket 455 will also push the rack b454 and the rigid tube b42 to move synchronously. The moving rack b454 drives the gear 452 to rotate, so that the rotating gear 452 can drive the rack a451 to move towards the inside of the housing 1. As the rack a451 moves, it will drive the rigid tube a41 to move towards the inside of the housing 1, thereby allowing the rigid tube a41 to be drawn into the inside of the housing 1, so as to prevent the presence of the rigid tube a41 from hindering the ball head 31 from continuing to move towards the human throat.

[0044] In the above process, to ensure that the moving direction of the rigid tube a41 remains unchanged, such as Figure 6As shown, guide blocks 411 are fixed on both the front and rear sides of the end of the rigid tube a41 inserted into the housing 1. A round rod 412 passes through the guide block 411. Fixing plates 413 are fixed at both ends of the round rod 412. The fixing plates 413 are fixed to the inner wall of the housing 1. When the rigid tube a41 moves, it can drive the guide block 411 to slide along the outer wall of the round rod 412, thereby keeping the moving direction of the rigid tube a41 from deviating.

[0045] In addition, such as Figure 7 and 8 As shown, a base 6 is provided on the outside of the handle 2. The top of the base 6 contacts the bottom of the housing 1, so that the base 6 can support the housing 1 from the bottom. In addition to being handheld during transportation, the base 6 can also be placed on the bedside table in the ward, and the handle 2 can be inserted into the base 6 to facilitate the placement of the present invention in the ward, thereby making it convenient to use the present invention to suction phlegm for patients in the ward.

[0046] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
