Description

Technical Field

[0001] The present invention relates to the technical field of nursing sputum aspiration, and particularly to a sputum aspiration device for intensive care medicine nursing. Background Art

[0002] The sputum aspiration device in intensive care medicine nursing is a medical device used to help clear the respiratory tract secretions of patients. In the intensive care environment, patients may not be able to effectively clear the secretions in the respiratory tract autonomously due to various reasons, which may lead to problems such as airway obstruction or pulmonary infection. Therefore, the use of a sputum aspiration device is very important for maintaining airway patency and reducing complications.

[0003] Chinese Patent Publication No. CN219764095U, published on September 29, 2023, discloses a sputum aspiration device, which includes a sputum aspiration mechanism, a sputum drainage mechanism, and an anti-slip mechanism. The sputum aspiration mechanism includes a top cover, a locking thread, a sputum aspiration tube, an air suction tube, an air plug port, and a power unit. The sputum drainage mechanism includes a sputum storage bottle, an inner bile duct, and a cleaning plate. The anti-slip mechanism includes a bottom cover, an anti-slip patch, and a fixing buckle. An air suction tube is provided on one side of the power unit. The inner surface of the top cover is respectively connected to the outer sides of the sputum aspiration tube and the air suction tube. A cleaning plate is provided inside the top tube. An inner bile duct is provided inside the sputum storage bottle.

[0004] Most of the existing sputum aspiration devices such as the above are composed of three parts: a sputum aspiration component, a liquid collection bottle, and a negative pressure generating component. Negative pressure is generated by pushing and pulling the piston rod to suck the sputum into the liquid collection bottle. In the specific implementation process, in order to avoid the backflow of saliva and water in the liquid collection bottle, the negative pressure generating component can only be stretched horizontally, which limits the use method of the sputum aspiration device. Therefore, it is urgent to propose a corresponding sputum aspiration device for intensive care medicine nursing to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to propose a sputum aspiration device for intensive care medicine nursing in order to solve the above problems.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions: A sputum aspiration device for intensive care medicine nursing includes a cover plate and a suction tube. The bottom of the cover plate is screwed with a liquid collection bottle. A return tube and a negative pressure tube are fixedly connected to the middle of the cover plate. The suction tube is fixedly connected to the open end of the return tube through a joint. The top of the cover plate is integrated with a suction cylinder and a positioning component for positioning the orientation of the suction cylinder. The bottom of the suction cylinder is connected to the negative pressure tube through a corrugated pipe. The inside of the suction cylinder is integrated with a lifting component for generating negative pressure. The outer wall of the suction cylinder is fixedly connected with an outer frame. The outer frame is integrated with a handle and a fixing component for adjusting the position of the handle.

[0007] Preferably, the joint is sleeved on the open end of the return pipe. An outer frame is fixedly connected to the outer surface wall of the return pipe. Two pressing frames and a pushing part for pushing the two pressing frames to move relative to each other are integrated inside the outer frame.

[0008] Preferably, the pushing assembly includes a rotating rod rotatably connected to the inner surface wall of the outer frame. The outer surface wall of the rotating rod is threadedly connected to the two pressing frames through two opposite threaded grooves respectively. A smooth rod slidably connected to the two pressing frames is fixedly connected to the inner surface wall of the outer frame.

[0009] Preferably, a connecting frame is fixedly connected to the outer surface wall of the outer frame. The connecting frame is fixedly connected to the outer surface wall of the return pipe through a locking rod.

[0010] Preferably, the lifting assembly includes a pull rod threadedly connected to the inner surface wall of the suction cylinder. A piston is fixedly connected to the bottom of the pull rod. A spring is fixedly connected between the top of the piston and the inner surface wall of the top of the suction cylinder.

[0011] Preferably, the positioning assembly includes a fixing frame fixedly connected to the top of the cover plate. A sliding sleeve fixedly connected to the outer surface wall of the suction cylinder is sleeved on the fixing frame. A fixing rod is threadedly connected to the outer surface wall of the sliding sleeve, and the open end of the fixing rod abuts against the outer surface wall of the fixing frame.

[0012] Preferably, the fixing component includes a positioning rod threadedly connected to the outer surface wall of the outer frame, and the open end of the positioning rod is fixedly connected to the outer surface wall of the vertical end of the handle.

[0013] Preferably, a limiting block is fixedly connected to the bottom of the vertical end of the handle. The outer surface wall of the limiting block is slidably connected to the inner surface wall of the outer frame.

[0014] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows: 1. In this application, when the suction cylinder is toggled, the sliding sleeve slides along the arc end of the fixing frame, thereby restricting the deflection direction of the suction cylinder and the deformation state of the corrugated pipe. Until the pull rod deflects to a suitable orientation relative to the liquid collection bottle, the corrugated pipe undergoes corresponding deformation. Rotate the fixing rod to thread it with the sliding sleeve, and fix the sliding sleeve and the suction cylinder through the contact friction between the fixing rod and the outside of the fixing frame. After adjusting the distance between the handle and the open end of the pull rod to a suitable range, fix the handle and the outer frame through the positioning rod, and fix the straw and the return pipe through the clamping of the joint. The operator places the palm of the hand against the handle and the fingers overlap on the open end of the pull rod, and pushes and pulls the piston rod through the pull rod, thereby generating a negative pressure change in the liquid collection bottle. The sputum is then drawn into the liquid collection bottle through the straw and the return pipe. In this way, the orientation of the overall negative pressure generating component can be adjusted according to the operator's usage habits, and at the same time, the maximum stroke of the pull rod can be restricted by the handle. The operator can adjust a suitable negative pressure change according to the specific situation, which can avoid damage to the patient's mucosal tissue caused by excessive negative pressure change.

[0015] 2. In this application, after the joint is sleeved onto the open end of the return pipe, the rotating rod is rotated. The rotating rod is screwed with two pressing frames through two groups of opposite thread grooves on the outer surface wall. The two pressing frames move relative to each other along the smooth rod until both pressing frames are pressed against the outside of the joint, thereby maintaining the stability of the connection between the joint and the return pipe. While ensuring the stable cooperation between the return pipe and the suction pipe, it replaces the traditional screwing connection method and ensures the subsequent quick disassembly and assembly of the suction pipe and the joint.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Please refer to Figures 1-5 , the present invention provides a technical solution: A sputum suction device for critical care nursing, comprising a cover plate 1 and a suction pipe 6. A liquid collection bottle 2 is screwed to the bottom of the cover plate 1. A return pipe 3 and a negative pressure pipe 4 are fixedly connected to the middle of the cover plate 1. The suction pipe 6 is fixedly connected to the open end of the return pipe 3 through a joint 5. A suction cylinder 11 and a positioning assembly for positioning the suction cylinder 11 are integrated on the top of the cover plate 1. The bottom of the suction cylinder 11 is connected to the negative pressure pipe 4 through a corrugated pipe 10. A lifting assembly for generating negative pressure is integrated inside the suction cylinder 11. An outer frame 12 is fixedly connected to the outer surface wall of the suction cylinder 11. The outer frame 12 is integrated with a handle 13 and a fixing assembly for adjusting the position of the handle 13; Dial the suction cylinder 11, and the sliding sleeve 20 slides along the arc end of the fixing frame 19, so as to limit the deflection direction of the suction cylinder 11 and the deformation state of the corrugated pipe 10. Until the pull rod 15 deflects to a suitable orientation relative to the liquid collection bottle 2, the corrugated pipe 10 undergoes corresponding deformation. Rotate the fixing rod 21 to screw it with the sliding sleeve 20, and realize the fixation of the sliding sleeve 20 and the suction cylinder 11 through the contact friction between the fixing rod 21 and the outer side of the fixing frame 19. After adjusting the distance between the handle 13 and the open end of the pull rod 15 to a suitable range, fix the handle 13 and the outer frame 12 through the positioning rod 14, and realize the fixation of the suction pipe 6 and the return pipe 3 through the clamping of the joint 5. The operator places the palm against the handle 13 and the fingers overlap the open end of the pull rod 15, and pushes and pulls the piston 23 through the pull rod 15, so as to generate a negative pressure change in the liquid collection bottle 2, and the sputum is extracted into the liquid collection bottle 2 through the suction pipe 6 and the return pipe 3. In this way, the overall orientation of the negative pressure generating assembly can be adjusted according to the operator's usage habits, and at the same time, the maximum stroke of the pull rod 15 can be limited by the handle 13. The operator can adjust a suitable negative pressure change according to the specific situation, and can avoid damage to the patient's mucosal tissue caused by excessive negative pressure change.

[0020] Specifically, as Figure 2 shown in Figure 4 As shown, the joint 5 is sleeved on the open end of the return pipe 3. An outer frame 7 is fixedly connected to the outer surface wall of the return pipe 3. Two sets of pressure frames 17 and a pushing part for promoting the relative movement of the two sets of pressure frames 17 are integrated inside the outer frame 7. The pushing part includes a rotating rod 16 rotatably connected to the inner surface wall of the outer frame 7. The outer surface wall of the rotating rod 16 is screwed to the two sets of pressure frames 17 through two sets of opposite thread grooves respectively. A smooth rod 18 slidably connected to the two sets of pressure frames 17 is fixedly connected to the inner surface wall of the outer frame 7. After the joint 5 is sleeved on the open end of the return pipe 3, rotate the rotating rod 16. The rotating rod 16 is screwed to the two sets of pressure frames 17 through two sets of opposite thread grooves on the outer surface wall. The two sets of pressure frames 17 move relatively along the smooth rod 18 until the two sets of pressure frames 17 are both pressed against the outside of the joint 5, so as to maintain the stable connection between the joint 5 and the return pipe 3. While ensuring the stable cooperation between the return pipe 3 and the suction pipe 6, it replaces the traditional way of screw connection, and ensures the subsequent quick disassembly and assembly of the suction pipe 6 and the joint 5.

[0021] Specifically, asFigure 2 As shown in Figure 3 , on the outer surface wall of the outer frame 7, there is a fixedly connected connecting frame 8. The connecting frame 8 is fixedly connected to the outer surface wall of the return pipe 3 through a locking rod 9, so as to ensure the convenience of disassembly and assembly of the outer frame 7. The lifting assembly includes a pull rod 15 screwed to the inner surface wall of the suction cylinder 11. At the bottom of the pull rod 15, there is a fixedly connected piston 23. Between the top of the piston 23 and the inner surface wall of the top of the suction cylinder 11, there is a fixedly connected spring 22. The operator places the palm against the handle 13 and the fingers overlap on the open end of the pull rod 15, and pushes and pulls the piston 23 through the pull rod 15, thereby generating a negative pressure change in the liquid collection bottle 2. The positioning assembly includes a fixed frame 19 fixedly connected to the top of the cover plate 1. The fixed frame 19 is sleeved with a sliding sleeve 20 fixedly connected to the outer surface wall of the suction cylinder 11. On the outer surface wall of the sliding sleeve 20, there is a screwed fixed rod 21, and the open end of the fixed rod 21 abuts against the outer surface wall of the fixed frame 19. The sliding sleeve 20 slides along the arc end of the fixed frame 19, thereby restricting the deflection direction of the suction cylinder 11 and the deformation state of the corrugated pipe 10. Until the pull rod 15 deflects to a suitable orientation relative to the liquid collection bottle 2, the corrugated pipe 10 undergoes a corresponding degree of deformation. Rotate the fixed rod 21 to screw it with the sliding sleeve 20, and realize the fixation of the sliding sleeve 20 and the suction cylinder 11 through the contact friction between the fixed rod 21 and the outside of the fixed frame 19.

[0022] Specifically, as shown in Figure 1 As shown in Figure 2 , the fixing assembly includes a positioning rod 14 screwed to the outer surface wall of the outer frame 12, and the open end of the positioning rod 14 is fixedly connected to the outer surface wall of the vertical end of the handle 13. The maximum stroke of lifting the pull rod 15 is restricted by the handle 13. The operator can adjust a suitable negative pressure change according to the specific situation, which can avoid damage to the patient's mucosal tissue caused by excessive negative pressure change. At the bottom of the vertical end of the handle 13, there is a fixedly connected limit block 24. The outer surface wall of the limit block 24 is slidably connected to the inner surface wall of the outer frame 12, so that the handle 13 can be completely separated from the outer frame 12.

[0023] Working principle: Toggle the suction cylinder 11, and the sliding sleeve 20 slides along the arc end of the fixed frame 19, thereby restricting the deflection direction of the suction cylinder 11 and the deformation state of the corrugated pipe 10. Until the pull rod 15 deflects to a suitable orientation relative to the liquid collection bottle 2, the corrugated pipe 10 undergoes corresponding deformation. Rotate the fixed rod 21 to thread it with the sliding sleeve 20, and fix the sliding sleeve 20 and the suction cylinder 11 through the contact friction between the fixed rod 21 and the outer side of the fixed frame 19. After adjusting the distance between the adjusting handle 13 and the open end of the pull rod 15 to a suitable range, fix the handle 13 and the outer frame 12 through the positioning rod 14. Fix the suction pipe 6 and the return pipe 3 through the engagement of the joint 5. The operator places the palm of the hand against the handle 13 and the fingers on the open end of the pull rod 15, and pushes and pulls the piston 23 through the pull rod 15, thereby generating a negative pressure change in the liquid collection bottle 2, and the sputum is extracted into the liquid collection bottle 2 through the suction pipe 6 and the return pipe 3. In this way, the overall orientation of the negative pressure generating component can be adjusted according to the operator's usage habits, and at the same time, the maximum stroke of the pull rod 15 can be restricted by the handle 13. The operator can adjust a suitable negative pressure change according to the specific situation, which can avoid damage to the patient's mucosal tissue caused by excessive negative pressure change. After sleeving the joint 5 onto the open end of the return pipe 3, rotate the rotating rod 16. The rotating rod 16 is threaded with the two pressing frames 17 through two groups of opposite threaded grooves on the outer surface wall. The two pressing frames 17 move relative to each other along the optical rod 18 until both pressing frames 17 are pressed against the outside of the joint 5, thereby maintaining the stability of the connection between the joint 5 and the return pipe 3. While ensuring the stable cooperation between the return pipe 3 and the suction pipe 6, it replaces the traditional screw connection method and ensures the subsequent quick disassembly and assembly of the suction pipe 6 and the joint 5.
