Description

Technical Field

[0001] This utility model relates to the technical field of oral secretion aspiration devices; more specifically, it relates to a continuous oral secretion aspiration device. Background Technology

[0002] Oral secretions are mainly produced by the normal physiological activities and pathological reactions of the salivary glands. Under normal circumstances, saliva is continuously secreted by the parotid gland, submandibular gland and sublingual gland, and is regulated by the autonomic nervous system. It has the functions of lubricating the oral cavity, aiding digestion and inhibiting bacteria. When patients have diseases, the amount or characteristics of secretions may be abnormal. In addition, patients who are in a coma or have impaired consciousness are prone to the accumulation of secretions due to muscle relaxation, which needs to be dealt with in time to prevent aspiration.

[0003] Currently, existing oral secretion suction devices have several drawbacks. For some patients who are unable to manage their oral secretions independently, this can lead to leakage or backflow of secretions into the airway. This not only causes skin dampness but also affects the patient's breathing, reducing the device's safety. Furthermore, existing devices generally have a simple structure, which may result in air leakage due to incomplete sealing of the patient's mouth, leading to ineffective suction and diminishing the device's practicality. Therefore, a continuous oral secretion suction device is urgently needed to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a continuous suction device for oral secretions to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a continuous suction device for oral secretions, comprising:

[0006] The mounting cover has a collection tank threadedly connected to the outer surface of its lower end, a valve threadedly connected to the outer surface of the middle position of the upper end of the mounting cover, an attraction structure provided on the outer surface of one end of the upper end of the mounting cover, and a connecting pipe provided on the outer surface of the other end of the upper end of the mounting cover, with a fixing structure provided at the upper end of the connecting pipe.

[0007] The suction structure includes a connecting hole, which is located inside the outer surface of one end of the upper end of the mounting cover.

[0008] The fixing structure includes a baffle, which is fixedly connected to the outer surface of one end of the connecting pipe.

[0009] Preferably, the suction structure further includes a suction tube, which is fixedly connected to the outer surface of the upper end of the mounting cover at the position of the connecting hole. A movable tube is inserted inside the suction tube, and a control hole is opened inside the lower outer surface of the movable tube. A control ball is engaged inside the lower end of the movable tube. A limit rod is fixedly connected inside the movable tube, and a handle is fixedly connected to the upper outer surface of the movable tube. This design allows the movable tube to move up and down inside the suction tube.

[0010] Preferably, the external dimensions of the moving tube are adapted to the internal dimensions of the suction tube, the position of the control hole corresponds to the position of the connecting hole, and the internal dimensions of the control hole are larger than the internal dimensions of the connecting hole. This design makes the moving tube more stable when it moves up and down inside the suction tube.

[0011] Preferably, the control ball is made of rubber, and the outer size of the control ball is larger than the inner size of the control hole. This design improves the airtightness between the control ball and the control hole by utilizing the elasticity and toughness of the control ball's own material.

[0012] Preferably, the fixing structure further includes a suction head, which is fixedly connected to the inside of the baffle at the middle position. The two ends of the baffle are respectively hinged to a first strap and a second strap. A female Velcro is fixedly connected to the outer surface of one end of the first strap, and a female Velcro is fixedly connected to the outer surface of the other end of the second strap. This design allows the suction head to be inserted into the patient's mouth to absorb the patient's oral secretions.

[0013] Preferably, the suction head is made of silicone, and the outer length of the child hook and loop fastener is smaller than that of the mother hook and loop fastener. This design reduces patient discomfort by utilizing the elasticity and biocompatibility of the suction head material itself.

[0014] The technical effects and advantages of this utility model are as follows: By pulling the handle upward, the moving tube moves upward, drawing air from inside the collection tank into the suction tube. Simultaneously, the control ball moves downward and presses against the outer surface of the upper end of the control hole. The elasticity and toughness of the control ball's material improve the airtightness between the control ball and the control hole, thus blocking the control hole and preventing air from inside the moving tube from re-entering the collection tank through the control hole. This reduces the air pressure inside the collection tank, allowing the patient's oral secretions to pass through the suction head and into the collection tank via the connecting tube. Pressing the handle downward moves the moving tube downward, expelling air from inside the suction tube. By repeatedly pushing the handle up and down, the patient's oral secretions can be continuously suctioned, avoiding situations where patients have difficulty managing their oral secretions and improving the safety of the device to a certain extent.

[0015] By inserting the suction head into the patient's mouth, then wrapping the first and second straps around the patient's head and securing them tightly, and attaching the sub-hook and loop fastener to the appropriate position of the main hook and loop fastener, the baffle can be fitted tightly to the patient's face according to the patient's actual situation. This reduces the gap between the baffle and the patient's face, thereby improving the efficiency of the device in suctioning oral secretions and enhancing its practicality to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The oral secretion suction device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] like Figure 1 and Figure 2 As shown, this embodiment proposes a continuous oral secretion suction device, comprising:

[0024] Mounting cover 1, with a collection tank 2 threadedly connected to the outer surface of the lower end of mounting cover 1, a valve 3 threadedly connected to the outer surface of the middle position of the upper end of mounting cover 1, and an attraction structure 4 provided on the outer surface of one end of the upper end of mounting cover 1, and a connecting pipe 5 provided on the outer surface of the other end of the upper end of mounting cover 1, with a fixing structure 6 provided at the upper end of the connecting pipe 5.

[0025] The suction structure 4 includes a connecting hole 41, which is located inside the outer surface of one end of the upper end of the mounting cover 1. The suction structure 4 also includes a suction tube 42, which is fixedly connected to the outer surface of the upper end of the mounting cover 1 at the position of the connecting hole 41. A movable tube 43 is inserted inside the suction tube 42, and a control hole 44 is opened inside the lower outer surface of the movable tube 43. The external dimensions of the movable tube 43 are adapted to the internal dimensions of the suction tube 42. The position of the control hole 44 corresponds to the position of the connecting hole 41, and the internal dimensions of the control hole 44 are larger than the internal dimensions of the connecting hole 41. This design allows the movable tube 43 to move up and down inside the suction tube 42. At the same time, the movable tube 43 is more stable when it moves inside the suction tube 42, and can prevent air from leaking from the gap between the suction tube 42 and the movable tube 43. At the same time, when the movable tube 43 moves inside the suction tube 42, it can drive the air inside the collection tank 2 to flow into the suction tube 42 through the connecting hole 41 and the control hole 44.

[0026] Furthermore, a control ball 45 is internally engaged at the lower end of the moving tube 43, a limit rod 46 is fixedly connected inside the moving tube 43, and a handle 47 is fixedly connected to the outer surface of the upper end of the moving tube 43. The control ball 45 is made of rubber, and the external size of the control ball 45 is larger than the internal size of the control hole 44. This design improves the airtightness between the control hole 44 and the control ball 45 by utilizing the elasticity and toughness of the material of the control hole 44 itself. When the moving tube 43 moves upward, it drives the control ball 45 to move downward and press against the upper end of the control hole 44. Thus, while drawing air from inside the collection tank 2 into the suction tube 42, it prevents air from inside the moving tube 43 from leaking into the suction tube 42 from inside the control hole 44.

[0027] Example 2

[0028] like Figure 3 and Figure 4 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0029] The fixing structure 6 includes a baffle 61, which is fixedly connected to the outer surface of one end of the connecting tube 5. The fixing structure 6 also includes a suction head 62, which is fixedly connected to the inside of the baffle 61 at the middle position. The two ends of the baffle 61 are respectively hinged to a first strap 63 and a second strap 64. A sub-hook and loop fastener 65 is fixedly connected to the outer surface of one end of the first strap 63, and a female hook and loop fastener 66 is fixedly connected to the outer surface of the other end of the second strap 64. The suction head 62 is made of silicone. The outer length of the sub-hook and loop fastener 65 is smaller than the outer length of the female hook and loop fastener 66.

[0030] In this embodiment, by inserting the suction head 62 into the patient's mouth, the elasticity and biocompatibility of the suction head 62 itself can prevent the patient from experiencing discomfort. By wrapping the first strap 63 and the second strap 64 around the patient's head and tightening the hook and loop fastener 65 to fit the mother hook and loop fastener 66 at a suitable position, the baffle 61 can be tightly fitted to the patient's face, which can reduce air leakage when the device is suctioning oral secretions and improve the efficiency of suctioning secretions.

[0031] Working principle: When using the device, first insert the suction head 62 into the patient's mouth, and simultaneously attach the first strap 63 and the second strap 64 tightly to the patient's head. Then, attach the female Velcro 65 to the female Velcro 66 at the appropriate position, so that the baffle 61 can be tightly attached to the patient's face, thus completing the installation of the fixing structure 6. Then, repeatedly push and pull the handle 47 up and down to expel the air inside the collection can 2 through the suction tube 42, thereby continuously reducing the air pressure inside the collection can 2. This allows the suction head 62 to continuously suck up the patient's oral secretions through the connecting tube 5. After the secretions are sucked up, rotate and open the valve 3 to balance the air pressure inside the collection can 2. Then, rotate the collection can 2 to remove it. The collected secretions can then be processed through the collection can 2. This is the complete working principle of this device.

[0032] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
