Description

Technical Field

[0001] This invention relates to the field of sputum suction technology in cardiology, and more particularly to a sputum suction device for cardiology. Background Technology

[0002] In cardiology and other related medical fields, suction devices are widely used as a key auxiliary device to clear sputum and other secretions from the throat, respiratory tract and trachea of ​​patients. This operation is of vital importance in maintaining the patient's airway and preventing the risk of suffocation or lung infection caused by sputum accumulation.

[0003] In routine medical care, sputum suctioning needs to be performed frequently, and the suction catheter needs to be changed regularly to ensure hygiene and safety. This process requires medical staff to have a high level of professional skills and meticulous operating techniques.

[0004] When not in use, suction catheters are generally directly exposed to the air in hospital wards or operating rooms. Although these places undergo strict disinfection, a large number of suspended particulate matter and potential pathogenic microorganisms still exist, especially in situations with frequent personnel movement or poor air circulation. These contaminants inevitably adhere to the surface of the suction catheter. Secondly, when medical staff prepare to connect the suction catheter to the suction device, they need to manually grasp one end of the suction catheter for connection. If the medical staff's hands are not completely clean or the surface of their gloves is contaminated, these contaminants will be further transferred to the suction catheter. Before the suction catheter is inserted into the patient's airway, a series of adjustment operations may be required, such as measuring the insertion depth and checking the patency of the catheter. These steps all increase the chance of the suction catheter coming into contact with external contaminants. If these contaminants enter the patient's airway through the suction catheter, they are very likely to cause serious secondary infections, such as pneumonia and bronchitis, significantly increasing the patient's pain burden and prolonging the length of hospital stay. Summary of the Invention

[0005] In view of this, the present invention provides a suction device for cardiology that can overcome the disadvantage that if contaminants enter the patient's respiratory tract through the suction tube, they are very likely to cause serious secondary infections.

[0006] A suction device for cardiology includes a negative pressure canister, a sealing cap, a negative pressure pump, a housing, a negative pressure hose, a suction tube, a connecting ring, a folded cloth sleeve, a sealing plug, and a sealing mechanism. The sealing cap is threadedly connected to the top of the negative pressure canister, and the negative pressure pump is installed on the top of the sealing cap. The suction end of the negative pressure pump communicates with the inside of the negative pressure canister. The housing is connected to the top of the sealing cap, and the housing communicates with the inside of the negative pressure canister. The negative pressure hose is connected to the top of the housing, and the suction tube is threadedly connected to the lower end of the negative pressure hose. The suction tube is connected to the lower part of the suction tube, and a folded cloth sleeve for protecting the suction tube is connected to the top of the connecting ring. The suction tube is located inside the folded cloth sleeve, and a sealing plug is threadedly connected to the upper end of the folded cloth sleeve. The sealing mechanism is used to seal the negative pressure hose, so that the inside of the negative pressure canister is kept in a vacuum state.

[0007] To further explain, the sealing mechanism includes a sealing box, a sealing plate, a sliding rod, and a spring. The lower part of the negative pressure hose is connected to the sealing box, and a sealing plate is slidably connected to the sealing box. The sealing plate is used to seal the negative pressure hose, keeping the inside of the negative pressure tank in a vacuum state. The sealing plate has a through hole. When the through hole corresponds to the negative pressure hose, the sputum in the patient's body is sucked into the negative pressure tank through the suction tube and the negative pressure hose. A sliding rod is connected to the sealing plate, and the sliding rod is slidably connected to the sealing box. A spring connects the sealing box and the sealing plate.

[0008] To further explain, it also includes an adjusting plate and an adjusting screw. The adjusting plate is slidably and sealingly connected to the housing, and the adjusting screw is rotatably connected to the housing. The adjusting screw and the adjusting plate are connected by threads.

[0009] To further explain, it also includes an installation ring and an activated carbon filter. The installation ring is connected to the discharge end of the negative pressure pump, and an activated carbon filter for purifying the odor emitted by sputum is connected to the installation ring by threads.

[0010] To further explain, it also includes a sealing ring, which is connected to the sealing box, and the sealing plate and the inner wall of the sealing ring are in contact.

[0011] To further explain, it also includes a conical suction tip, with the upper end of the suction tube connected to the conical suction tip.

[0012] To further explain, the edges of the conical suction head are chamfered.

[0013] To further clarify, the adjustment plate is set at an angle.

[0014] Further explanation: It also includes a rubber ring, a limiting ring, a connecting block, a rotating shaft, a rotating frame, a tension spring, a pressure roller, a damping ring, a knob, and a conical hopper. The upper part of the folded cloth cover is connected to a rubber ring, and the suction tube contacts the inner wall of the rubber ring. The upper end of the folded cloth cover is connected to a limiting ring. The negative pressure tubing is connected to a connecting block. The connecting block is rotatably connected to rotating shafts on both the front and rear sides and the left and right sides. Two adjacent rotating shafts are driven by bevel gears. Each rotating shaft is connected to a rotating frame. A tension spring is connected between the rotating frame and the connecting block. Each rotating frame is rotatably connected to a pressure roller for pressing down the folded cloth cover. Two adjacent pressure rollers are driven by bevel gears. Each rotating frame is connected to a damping ring, and the pressure roller contacts the inner wall of the damping ring. One of the pressure rollers is connected to a knob. The connecting ring is connected to a conical hopper. The suction tube and the folded cloth cover are both located inside the conical hopper.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention uses a negative pressure pump to extract air from the negative pressure tank, maintaining a vacuum state inside. Sputum enters the negative pressure tank through the suction tube for suctioning. The folded cloth cover and sealing plug protect the suction tube, preventing contaminants from adhering to it. By inserting the suction tube into the patient's throat, respiratory tract, or trachea in a contactless manner, it effectively prevents contaminants from adhering to the suction tube, thereby preventing contaminants from entering the patient's throat, respiratory tract, or trachea and thus avoiding serious secondary infections.

[0017] 2. By rotating the adjusting screw, the adjusting plate can be moved left and right to adjust the distance between the right side of the adjusting plate and the right side of the housing, thereby adjusting the suction force. The suction force can be adjusted according to the patient's condition to avoid excessive suction force causing injury to the patient.

[0018] 3. The activated carbon filter can purify the odor emitted by sputum, preventing the odor from polluting the ward environment, thus avoiding discomfort for patients and reducing the risk of cross-infection. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0034] Reference Figures 1-5A suction device for cardiology includes a negative pressure canister 1, a sealing cap 2, a negative pressure pump 3, a housing 4, a negative pressure hose 5, a suction tube 6, a connecting ring 7, a folded cloth cover 8, a sealing plug 9, and a sealing mechanism. The top of the negative pressure canister 1 is connected to the sealing cap 2 by threads. The negative pressure pump 3 is bolted to the left side of the top of the sealing cap 2. The suction end of the negative pressure pump 3 communicates with the inside of the negative pressure canister 1. The right side of the top of the sealing cap 2 is bolted to the housing 4. The housing 4 communicates with the inside of the negative pressure canister 1. The top of the housing 4 is connected to the negative pressure hose 5. The lower end of the negative pressure hose 5 is threaded to the suction tube 6. The lower part of the suction tube 6 is connected to the connecting ring 7. The top of the connecting ring 7 is connected to the folded cloth cover 8. The suction tube 6 is located inside the folded cloth cover 8. The negative pressure canister 1, the housing 4, the negative pressure hose 5, the suction tube 6, and the folded cloth cover 8 are all made of transparent material. The upper end of the folded cloth cover 8 is threaded to the sealing plug 9. The sealing mechanism is used to seal the negative pressure hose 5, so that the inside of the negative pressure canister 1 is kept in a vacuum state.

[0035] Reference Figures 3-5 The sealing mechanism includes a sealing box 101, a sealing plate 102, a sliding rod 104, and a spring 105. The lower part of the negative pressure hose 5 is connected to the sealing box 101. The sealing plate 102 is slidably and sealingly connected to the front side of the sealing box 101. A through hole 103 is opened in the middle of the sealing plate 102. Sliding rods 104 are connected to both sides of the sealing plate 102. The sliding rods 104 are slidably connected to the front side of the sealing box 101. Springs 105 are sleeved on the sliding rods 104. The two ends of the springs 105 are connected to the sealing box 101 and the sealing plate 102 respectively. The springs 105 are sleeved on the sliding rods 104 to prevent the springs 105 from bending.

[0036] Initially, the sealing plate 102 seals the negative pressure hose 5. Medical staff activate the negative pressure pump 3, which draws air from the negative pressure tank 1. At this time, the sealing plate 102 seals the negative pressure hose 5, creating a vacuum inside the negative pressure tank 1. The sealing plate 102 maintains this vacuum by continuously sealing the negative pressure hose 5. The folded cloth cover 8 and the sealing plug 9 protect the suction tube 6, preventing contaminants from adhering to it. Medical staff then remove the sealing plug 9, place the folded cloth cover 8 near the patient's mouth, and push the suction tube 6 to insert it into the patient's throat, respiratory tract, or trachea. The folded cloth cover 8 folds and shortens, allowing the suction tube 6 to be inserted into the patient's throat, respiratory tract, or trachea without contact. Inside the tube, contaminants can be effectively prevented from adhering to the suction tube 6, thereby preventing contaminants from entering the patient's throat, respiratory tract, or trachea, and thus preventing serious secondary infections. After the suction tube 6 is extended to the suction position, the medical staff pushes the sealing plate 102 backward, and the spring 105 is compressed. When the through hole 103 corresponds to the negative pressure hose 5, the sputum in the patient's body is sucked into the negative pressure canister 1 through the suction tube 6 and the negative pressure hose 5 for suctioning. The negative pressure canister 1, shell 4, negative pressure hose 5, suction tube 6, and folded cloth cover 8 are all made of transparent material, so the suctioning process can be observed. After the suctioning is completed, the suction tube 6 is removed from the patient's body, and then the sealing plate 102 is released. Under the action of the spring 105, the sealing plate 102 moves forward to reset.

[0037] Reference Figure 6 and Figure 7 It also includes an adjusting plate 111 and an adjusting screw 112. The adjusting plate 111 is slidably and sealingly connected to the left side of the housing 4. The adjusting plate 111 is inclined. The adjusting screw 112 is rotatably connected to the left side of the housing 4. The adjusting screw 112 and the adjusting plate 111 are connected by threads.

[0038] Children's respiratory mucosa is more fragile, and excessive suction force may cause mucosal damage, bleeding, or even ulcers. Elderly patients may experience changes in their tracheal structure due to age, such as decreased elasticity and increased secretions, and excessive suction force may damage the trachea. Medical staff can rotate the adjusting screw 112 to move the adjusting plate 111 left and right, adjusting the distance between the right side of the adjusting plate 111 and the right side inside the housing 4, thereby adjusting the suction force. Increasing the distance between the right side of the adjusting plate 111 and the right side inside the housing 4 can increase the suction force, and decreasing the distance can decrease the suction force. The suction force can be adjusted according to the patient's condition to avoid excessive suction force causing injury to the patient. The adjusting plate 111 is tilted, allowing sputum to flow downwards along the adjusting plate 111, avoiding excessive sputum residue on the adjusting plate 111.

[0039] Reference Figure 8It also includes an installation ring 121 and an activated carbon filter element 122. The installation ring 121 is connected to the discharge end of the negative pressure pump 3, and the activated carbon filter element 122 is connected to the installation ring 121 by threads.

[0040] When the negative pressure pump 3 draws air from the negative pressure tank 1, the odor emitted by the sputum is also drawn into the negative pressure pump 3. The activated carbon filter 122 can purify the odor emitted by the sputum, preventing the odor from polluting the environment in the ward, thus avoiding discomfort for patients in the ward and reducing the risk of cross-infection. The activated carbon filter 122 can be disassembled and replaced to ensure the purification effect.

[0041] Reference Figure 4 and Figure 5 It also includes a sealing ring 13. The sealing box 101 is connected to the front side of the sealing ring 13. The sealing plate 102 is in contact with the inner wall of the sealing ring 13. The sealing ring 13 can seal the gap between the sealing box 101 and the sealing plate 102 to prevent air leakage.

[0042] Reference Figure 9 It also includes a conical suction head 14. The upper end of the suction tube 6 is connected to the conical suction head 14. The edges of the conical suction head 14 are chamfered. Through the action of the conical suction head 14, the resistance encountered when the suction tube 6 is inserted can be reduced, making it easier for the suction tube 6 to pass through narrow or curved parts of the trachea, reducing friction and damage to the trachea. Furthermore, the chamfered edges of the conical suction head 14 can further reduce friction and damage to the trachea.

[0043] Reference Figures 10-13 It also includes a rubber ring 15, a limiting ring 16, a connecting block 17, a rotating shaft 18, a rotating frame 19, a tension spring 20, a pressure roller 21, a damping ring 22, a knob 23, and a conical hopper 24. The upper part of the folded cloth cover 8 is connected to the rubber ring 15, and the suction tube 6 contacts the inner wall of the rubber ring 15. The upper end of the folded cloth cover 8 is connected to the limiting ring 16, and the lower part of the negative pressure tubing 5 is connected to the connecting block 17. The connecting block 17 is rotatably connected to the rotating shaft 18 on both the front and rear sides and the left and right sides. Two adjacent rotating shafts 18 are driven by bevel gears. A rotating frame 19 is connected to each of the rotating shafts 18. A tension spring 20 is connected between the rotating frame 19 and the connecting block 17. A pressure roller 21 is rotatably connected to the upper part of the rotating frame 19. Two adjacent pressure rollers 21 are driven by bevel gears. A damping ring 22 is connected to the upper part of the rotating frame 19. The pressure roller 21 and the inner wall of the damping ring 22 are in contact. A knob 23 is connected to one of the pressure rollers 21. A conical hopper 24 is connected to the connecting ring 7. The suction tube 6 and the folded cloth cover 8 are both located inside the conical hopper 24. The lower part of the suction tube 6 is a rigid tube.

[0044] Medical staff attach the suction tube 6 to the negative pressure hose 5. The conical hopper 24 pushes the pressure roller 21, opening the rotating frame 19 and stretching the tension spring 20. The lower part of the suction tube 6 is a rigid tube, making it easy for medical staff to attach the suction tube 6 to the negative pressure hose 5. After the conical hopper 24 and the pressure roller 21 disengage, under the action of the tension spring 20, the four pressure rollers 21 move towards each other, contacting the folded cloth cover 8. Medical staff then place the limiting ring 16 in contact with the patient's mouth and turn the knob 23, causing the pressure roller 21 to rotate. The pressure roller 21 drives the other three pressure rollers 21 to rotate via bevel gears. The pressure roller 21 can pull the folded cloth cover 8, allowing the suction tube 6 to emerge from the folded cloth cover 8 and extend into the patient's throat, respiratory tract, or trachea. The folded cloth cover can be controlled according to the suction position. The traction distance of tube 8 is adjusted to prevent the suction tube 6 from extending too far. After the suction tube 6 reaches the suction position, the knob 23 is stopped. Under the action of the tension spring 20, the pressure roller 21 presses down the folded cloth cover 8, and the limiting ring 16 contacts the patient's mouth to prevent the suction tube 6 from moving freely. This prevents the suction tube 6 from scratching or abrading the mucous membrane of the respiratory tract and also prevents the folded cloth cover 8 from entering the patient's mouth. Under the action of the rubber ring 15, the resistance to the movement of the folded cloth cover 8 is increased. Under the action of the damping ring 22, the resistance to the rotation of the pressure roller 21 is increased, thus preventing the folded cloth cover 8 from moving freely. Rotating one of the rotating frames 19 can drive the other three rotating frames 19 to rotate together through the bevel gear, making it easier to turn the pressure roller 21 open so that the suction tube 6 can be removed from the negative pressure tubing 5.

All equivalent substitutions made within the principles of the present invention should be included within the scope of protection of the present invention. Contents not described in detail in this invention belong to existing technology known to those skilled in the art.
