Description

Technical Field

[0001] The present invention relates to a medical device, and in particular to a sputum suction device. Background Art

[0002] In the respiratory department, sputum suction is an important nursing operation, mainly used to remove secretions (sputum) in the patient's respiratory tract, maintain airway patency, and improve ventilation function. When performing sputum suction, a negative pressure suction device is often used to suck sputum. The sputum suction tube is inserted into the patient's mouth, rotated left and right, and the suction time is controlled not to exceed 15 seconds each time, with oxygen supply given at intervals. After the operation, the patient's reaction should be observed, and the nature and quantity of the sputum should be recorded.

[0003] When performing oral sputum suction, it greatly tests the operation level of medical staff. The currently used sputum suction devices are relatively slow in sputum suction efficiency during use. When encountering relatively viscous or stubborn sputum crusts, it is often very difficult to clean them; and due to reasons such as improper operation, it is easy to cause damage to the oral mucosa.

[0004] In view of the above problems, we provide a sputum suction device. Summary of the Invention

[0035] To enable those skilled in the art to better understand the technical solutions in this application, the following will clearly and completely describe the technical solutions in the embodiments of this application in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the protection scope of this application.

[0036] The embodiments of this application provide a sputum suction device.

[0037] Embodiment 1 is as Figure 1-6 shown.

[0038] A sputum suction device includes a main body box 1, the main body box 1 is a hollow box structure, and a handle 11 is arranged below the main body box 1. By holding the handle 11, the sputum suction device can be held by hand to perform sputum suction operations.

[0039] A sputum suction device includes a driving assembly 2, which is installed inside the main body box 1, and its output end extends outside the main body box 1.

[0040] The driving assembly 2 includes a motor 21, a slider 22, and a support frame 23. A motor 21 is installed on one side of the inner cavity of the main body box 1. The output shaft of the motor 21 extends outside the main body box 1 and is provided with a support frame 23. A number of sliders 22 are arranged outside the support frame 23. The other end of the slider 22 is slidably connected to the outside of the main body box 1. The other end of the support frame 23 is installed with a sputum suction assembly 3. The motor 21 uses a variable-speed motor 21. Facing sputum with different viscosities, different rotation speeds can be selected to better clean and aspirate the sputum. When the motor 21 starts, it drives the support frame 23 to rotate, and then drives the sputum suction assembly 3 inside it to rotate. The design of the slider 22 can increase the rotation stability of the support frame 23.

[0041] A sputum suction device includes a sputum suction assembly 3, which is installed at the output end of the driving assembly 2. Through the sputum suction assembly 3, the aspiration of sputum and the cleaning of stubborn sputum crusts are realized.

[0042] The sputum suction assembly 3 includes a return suction pipe 31, a rear end cover 32, a return suction pump 33, and a spiral return suction head 34. One end of the support frame 23 is provided with a rear end cover 32. The return suction pipe 31 is installed inside the rear end cover 32. The return suction pipe 31 has a certain flexibility and can change its shape to facilitate insertion into the patient's throat. The return suction pump 33 is installed outside the rear end cover 32. The return suction pump 33 is communicated with the inside of the rear end cover 32 through a pipeline. The outer end of the return suction pipe 31 is installed with a spiral return suction head 34. When the return suction pump 33 is started, the return suction pipe 31 and the spiral return suction head 34 are in a negative pressure state, and then sputum is sucked into them through the spiral return suction head 34. A receiving cavity 311 is provided at the rear of the return suction pipe 31. After the sputum is sucked into the spiral return suction head 34, it continues to move backward along the return suction pipe 31 until it flows into the receiving cavity 311. A blocking net is provided at the rear side port of the receiving cavity 311 to block the viscous sputum into the receiving cavity 311, avoiding blocking the return suction pipe 31 and affecting the negative pressure magnitude.

[0043] The spiral return suction head 34 includes a silica gel tube body 341 and a spring skeleton 342. A sputum suction hole 3411 is formed in the center of the silica gel tube body 341 along its length direction. The end of the sputum suction hole 3411 is fixedly connected to the end of the return suction pipe 31. The spring skeleton 342 is embedded in the silica gel tube body 341. A spiral groove 3412 is formed on the outer side wall of the silica gel tube body 341. A sputum suction area is provided at the head of the silica gel tube body 341. A plurality of sputum suction holes 3411 are formed in the sputum suction area. A double-layer film 4 is installed in the sputum suction hole 3411. The silica gel tube body 341 is injection-molded with medical-grade silica gel. The embedded spring skeleton 342 inside enhances the anti-bending property. At the same time, when the spiral return suction head 34 rotates, it can provide sufficient rotational support force to avoid twisting and breaking of the silica gel tube body 341 and random swinging. Solve the contradiction between flexibility and rigidity.

[0044] During use, sputum is sucked into the inside of the silica gel tube body 341 along the sputum suction hole 3411 and then flows inside the return suction pipe 31. Six sputum suction holes 3411 are formed and are distributed at equal intervals along the sputum suction area. Sputum is suctioned back from various angles.

[0045] The spiral groove 3412 extends spirally along the length direction of the silica gel tube body 341, and the groove depth gradually becomes shallower from the root to the head of the silica gel tube body 341. Guide the sputum to gather at the center of the head of the spiral return suction head 34 and reduce the adsorption of sputum on the side wall. When the sputum gathers at the head of the spiral return suction head 34, it is directly sucked into by the sputum suction hole 3411 to achieve the suction of sputum.

[0046] The spiral groove 3412 and the sputum suction hole 3411 work together. The spiral groove 3412 is responsible for guiding the flow, and the sputum suction hole 3411 focuses on adsorption. The functional partitioning of the two avoids mutual interference. The guiding function of the spiral groove 3412 enables sputum to converge more efficiently to the area of the sputum suction hole 3411, greatly improving the sputum suction speed. At the same time, the opening of the sputum suction hole 3411 avoids the physical undulating structure of the spiral groove 3412, keeps the adsorption surface flat, and reduces the mechanical stimulation to the patient's oral mucosa.

[0047] A sputum suction device includes a double-layer membrane 4 installed at the inhalation end of the sputum suction assembly 3. That is, the double-layer membrane 4 is installed on both sides of the sputum suction hole 3411. The double-layer membrane 4 is designed to prevent sputum from adhering and blocking the orifice.

[0048] The double-layer membrane 4 includes an outer layer membrane 41 and an inner layer membrane 42. The outer layer membrane 41 and the inner layer membrane 42 are respectively located at the outer and inner ends of the sputum suction hole 3411.

[0049] A cross-shaped slit 411 is cut through the middle of the outer layer membrane 41, with a thickness of 0.1 mm and a hydrophobic coating on the surface. It is in a closed state under normal conditions. Negative pressure response: When the negative pressure reaches a certain value, the cross-shaped slit 411 is sucked open to form an adsorption channel, and then sputum is aspirated back. When the negative pressure decreases, the outer layer membrane 41 closes again. Preliminary filtration: Block large pieces of sputum or foreign objects from directly entering the sputum suction hole 3411 to prevent the inner layer membrane 42 from being blocked; Mucosa protection: It is smooth and has no protrusions in the closed state, reducing friction with the airway wall. At the same time, a rounded corner is provided at the outer end of the sputum suction hole 3411. Through the setting of the rounded corner, the opening and closing of the outer layer membrane 41 are smoother.

[0050] A communication hole 421 is opened in the middle of the inner side membrane. The diameter of the communication hole 421 is smaller than the diameter of the sputum suction hole 3411. The thickness is 0.2 mm, and the edge is fixed to the hole wall of the sputum suction hole 3411. Flow control: Limit the single inhalation volume through the diameter of the communication hole 421 to avoid mucosal damage caused by excessive adsorption; Secondary anti-blocking: After the outer layer membrane 41 is opened, sputum is buffered through the cavity and evenly passes through the through holes of the inner layer membrane 42; Negative pressure balance: When the negative pressure is too high, the inner layer membrane 42 is deformed by the suction force to shrink the communication hole 421, automatically limiting the flow.

[0051] The design of the double-layer membrane 4 realizes: outer membrane blocking + inner membrane flow control. The nested design not only realizes the efficient inhalation of sputum but also reduces the risk of mucosal damage through physical pressure division.

[0052] The spiral groove 3412 and the double-layer film 4 cooperate with each other to: 1. Prevent blockage. The spiral groove 3412 reduces the accumulation of sputum on the outer wall of the tube body, reducing the risk of blockage of the sputum suction hole 3411; the double-layer film 4 structure (cross-shaped slit 411 + circular communication hole 421) further prevents viscous sputum from blocking. 2. Optimize dynamic adsorption. When the spiral suction head 34 works, the spiral groove 3412 generates centrifugal force, causing the sputum to concentrate towards the opening; while the double-layer film 4 adjusts the aperture according to the negative pressure to match the sputum flow rate.

[0053] A bending assembly 5 is installed on the front side of the main body box 1 to control the spiral suction head 34 to change direction, facilitating entry into the posterior part of the patient's oral cavity and the larynx.

[0054] The bending assembly 5 includes an extension rod 51, a swing ring 52, a mounting seat 53, a swing push rod 54, and a swing slider 55. An extension rod 51 is provided on the front side of the main body box 1. The front end of the extension rod 51 is rotatably connected to a swing ring 52. A mounting seat 53 is provided below the connection between the swing ring 52 and the extension rod 51. A swing push rod 54 is installed on one side of the mounting seat 53. The output end of the swing push rod 54 is rotatably connected to a swing slider 55. The other end of the swing slider 55 is slidably connected to the bottom surface of the extension rod 51. The swing ring 52 is composed of two half rings, and the two half rings are detachably buckled together to form the swing ring 52. The swing ring 52 is sleeved outside the return suction pipe 31 and is located at the position of the return suction pipe 31 and the spiral suction head 34. During use, by the telescopic movement of the swing push rod 54, the swing ring 52 is controlled to swing along the connection with the end of the extension rod 51, thereby driving the spiral suction head 34 to rotate upward or downward, facilitating entry into the posterior part of the patient's oral cavity and the larynx for sputum suction operation.

[0055] A humidifying assembly 6 is provided on the outer side of the swing ring 52 to moisten the sputum crust for easy cleaning and sputum suction.

[0056] The humidifying assembly 6 includes a spray pipe 61, a water storage tank 62, and a pump body 63. The spray pipe 61 is provided on the outer side of the upper half ring of the swing ring 52. A plurality of spray nozzles are installed on the surface of the spray pipe 61. The water storage tank 62 is installed on the top of the main body box 1. The pump body 63 is installed outside the water storage tank 62. The pump body 63 is communicated with the water storage tank 62 and the spray pipe 61 through pipelines. When the pump body 63 is started, the liquid in the water storage tank 62 is pumped into the spray pipe 61 and sprayed onto the stubborn sputum crust through the spray nozzles, realizing the moistening and softening of the sputum crust for subsequent cleaning.

[0057] When the present invention is in use:

[0058] For the medical staff's handheld device, after the patient opens their mouth, insert the spiral suction head deep into the patient's oral cavity, and then start the sputum suction operation. The motor and the suction pump are started. The motor drives the spiral suction head to rotate. The sputum at the head of the spiral suction head is directly sucked into it, while the sputum at the rear of the spiral suction head is guided by the spiral groove to gather towards the center of the head of the spiral suction head, reducing the adsorption of sputum on the side wall. When the sputum gathers at the head of the spiral suction head, it is directly sucked in through the sputum suction holes, realizing the suction of sputum.

[0059] When it is necessary to change the orientation of the spiral suction head, by the telescopic movement of the swing push rod, control the swing ring to swing along the connection with the end of the extension rod, thereby driving the spiral suction head to rotate upward or downward, and then facilitating the insertion into the rear part of the patient's oral cavity and the larynx for sputum suction operation.

[0060] When it is necessary to soften the sputum crust, the pump body is started to pump the liquid in the water storage tank into the spray pipe, and then sprayed onto the stubborn sputum crust through the nozzle, realizing the moistening and softening of the sputum crust, facilitating subsequent cleaning.
