Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a pneumothorax emergency device for cardiothoracic surgery. Background Technology

[0002] Pneumothorax is a pathological condition in which gas abnormally enters the pleural cavity, causing lung tissue to collapse under pressure and affecting normal respiratory function. Emergency treatment for pneumothorax patients requires different measures depending on the type and severity. The core is to quickly relieve pleural pressure and restore respiratory function. Among these measures, pneumothorax emergency devices are one of the important equipment for treating pneumothorax patients.

[0003] For example, Chinese patent CN216495902U discloses an open pneumothorax emergency care device. This device uses the cooperation between a threaded cylinder, a screw, a push rod, a block, a square groove, and a sleeve. The push rod can move into the inner cavity of the square cylinder through the gap cooperation with the sleeve, so that the push rod can press the top surface of the belt tightly, which can effectively improve the convenience and functionality of the care device during use.

[0004] While existing pneumothorax emergency devices allow for flexible adjustment of their placement, in practice, performing emergency procedures on pneumothorax patients requires vertical needle insertion at the second intercostal space along the midclavicular line on the affected side to expel air from the pleural cavity and relieve intrathoracic hypertension. Because the puncture depth must be manually controlled by medical personnel, errors can occur, posing a risk of accidental lung damage and thus negatively impacting the safety of the pneumothorax emergency device.

An anti-slip groove is provided on the lower end face of the elastic sleeve.

[0012] Optionally, a bladder is fixedly connected to the upper surface of the contact plate. The bladder is annular and surrounds the outside of the puncture tube. An annular rotating plate is rotatably mounted on the lower end face of the piston cylinder inside the second sleeve. The bottom surface of the rotating plate is connected to the top surface of the bladder. The bladder is connected to the inside of the elastic sleeve through a connecting tube.

[0013] Optionally, a cleaning component is provided on the lower side of the contact plate. The cleaning component includes a liquid storage cavity embedded in the inner side of the contact plate. An overflow hole is provided on the lower end face of the contact plate. The number of overflow holes is several and they are arranged in a ring array. A sliding groove is embedded in the inner wall of the overflow hole, and a sliding rod is slidably connected to the inner side of the sliding groove.

[0014] Optionally, a top rod is fixedly connected to the upper end face of the slide rod, and a contact block is fixedly connected to the lower end face of the slide rod. The outer surface of the contact block is arc-shaped, and a sealing membrane is fixedly connected to the inner surface of the overflow hole. The sealing membrane seals the connection between the overflow hole and the liquid storage chamber, and the liquid storage chamber is filled with disinfectant.

[0015] Optionally, a backflow assembly is provided inside the guide tube. The backflow assembly includes a first partition plate fixedly connected to the inner surface of the guide tube.

[0017] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0018] In the above scheme, by setting an adjustment component, the puncture depth of the puncture tube can be adjusted according to the differences in the patient's body size. This not only improves the operational accuracy of the pneumothorax emergency device during use, but also effectively reduces the probability of the puncture tube causing damage to the lungs, thereby effectively improving the safety and reliability of pneumothorax emergency treatment.

[0019] This solution, by setting up a fitting component, allows the anti-slip groove on the lower side of the elastic sleeve to effectively increase the friction between the sleeve and the skin, thereby effectively improving the stability of the contact plate during placement. At the same time, the elastic sleeve can deform according to the curvature of the patient's skin surface, thus maintaining a close fit with the patient's skin surface at all times. This not only effectively improves the stability of the emergency device during operation, but also further reduces the risk of accidental injury to the patient, thereby improving the safety of the emergency device to a certain extent.

[0020] This solution incorporates a cleaning component, allowing the disinfectant inside the reservoir to flow to the patient's skin surface through an overflow hole. The discharge of the disinfectant disinfects the puncture site, effectively reducing the risk of infection and further enhancing the safety of the emergency device during use.

[0038] like Figures 1 to 8As shown, this embodiment of the invention provides a pneumothorax emergency device for cardiothoracic surgery, including a piston cylinder 11. A piston plate 21 is slidably connected inside the piston cylinder 11. A puncture tube 20 is engaged and connected to the center of the bottom end of the piston cylinder 11. An adjustment assembly is provided on the lower side of the piston cylinder 11. The adjustment assembly includes a first sleeve 16 fixedly connected to the outer surface of the lower end of the piston cylinder 11. A second sleeve 18 is threadedly connected to the inner surface of the first sleeve 16. The puncture tube 20 passes through the first sleeve 16 and the second sleeve 18. A contact plate 15 is fixedly connected to the outer surface of the lower end of the second sleeve 18. The contact plate 15 has a central opening for the puncture tube 20 to pass through. A scale 19 is provided on the upper end of the contact plate 15. The scale 19 has an arc-shaped plate structure. The top of the scale 19 is arranged around the first sleeve 16. A scale line 17 is opened around the outer surface of the first sleeve 16. A guide tube 14 is connected to the bottom end of the piston cylinder 11.

[0039] The first sleeve 16, the second sleeve 18 and the contact plate 15 are all located outside the puncture tube 20. The piston rod 13 is fixedly connected to the upper end face of the piston plate 21. The compression plate 12 is fixedly connected to the upper end of the piston rod 13. The piston rod 13 passes through the top end of the piston cylinder 11 and is slidably connected to the piston cylinder 11. The lower end of the puncture tube 20 is inclined and sharp.

[0040] By adopting the above technical solution, when using the pneumothorax emergency device, the puncture tube 20 needs to be inserted into the patient's chest cavity. Then, the piston rod 13 is pulled by the compression plate 12. The piston rod 13 drives the piston plate 21 to move inside the piston cylinder 11. The pressure of the gas is used to draw out and expel the gas inside the patient's chest cavity through the puncture tube 20, thereby releasing the pressure inside the chest cavity. During the puncture of the puncture tube 20, in order to control the puncture depth and avoid damage to the patient's lungs from excessive puncture, an adjustment component is set. When adjusting the puncture depth, the operator drives the second sleeve 18 to rotate through the contact plate 15. The second sleeve 18 is threadedly connected to the first sleeve 16. As the second sleeve 18 rotates, the second sleeve 18 and the contact plate 15 move along the axis of the first sleeve 16. The contact plate 15 moves along the linear direction, and the distance between its lower surface and the lower end of the puncture tube 20 changes accordingly, thereby adjusting the length of the puncture tube 20 entering the pleural cavity. During the movement of the contact plate 15, the scale 19 moves synchronously and can move along the scale line 17. By comparing the scale 19 with the scale line 17 on the surface of the first sleeve 16, the position of the contact plate 15 can be precisely adjusted. By setting the adjustment component, the puncture depth of the puncture tube 20 can be adjusted according to the differences in the patient's body size. This not only improves the operational accuracy of the pneumothorax emergency device during use, but also effectively reduces the probability of the puncture tube 20 causing lung damage, thereby effectively improving the safety and reliability of pneumothorax emergency treatment.

[0041] like Figure 4 and Figure 5 As shown, a sealing assembly is provided on the upper side of the puncture tube 20. The sealing assembly includes a sealing sleeve 27 connected to the top end of the puncture tube 20. The sealing sleeve 27 is annular and made of wear-resistant elastic material. The sealing sleeve 27 is arranged around the inner wall of the top end of the puncture tube 20. A flow limiting valve 28 is provided inside the puncture tube 20. A traction strip 29 is fixedly connected to the outer surface of the upper end of the flow limiting valve 28. The traction strip 29 is made of elastic material.

[0042] A sealing block 25 is fixedly connected to the upper end of the traction bar 29. The sealing block 25 has an internal cavity 26 and a conical outer surface. A baffle 24, which is annular, is fixedly connected to the outer surface of the top of the sealing block 25. The baffle 24 surrounds the outer surface of the top of the sealing block 25. The top of the puncture tube 20 is inclined at the connection point with the piston cylinder 11. A sealing sleeve 27 is disposed on the inclined wall, and the inclination of the inclined wall matches the outer wall of the sealing block 25. The sealing block 25 is inserted into the top of the puncture tube 20, and the outer wall of the sealing block 25 contacts the sealing sleeve 27. The top diameter of the sealing block 25 is larger than the diameter of the puncture tube 20.

[0043] By adopting the above technical solution, a sealing component is set up to accurately control the gas inside the patient's chest cavity during emergency treatment. When the gas pressure inside the patient's chest cavity is too high, the gas will enter the puncture tube 20 and flow into the piston cylinder 11. At this time, the gas will push the baffle 24 and the sealing block 25 upward, causing the sealing block 25 to disengage from the outer surface of the sealing sleeve 27. Then, the gas enters the piston cylinder 11 through the gap between the sealing block 25 and the sealing sleeve 27. At the same time, under the action of gas pressure, the piston plate 21 will move upward. The cavity 26 inside the sealing block 25 can effectively reduce the weight of the sealing block 25, thereby reducing the resistance during the upward movement of the sealing block 25 to a certain extent. During the process, the traction bar 29 is pulled. When the piston plate 21 moves to the uppermost side to discharge the gas inside the piston cylinder 11, the sealing block 25 moves downward under the action of gas pressure, the pulling force of the traction bar 29, and the gravity of the sealing block 25. This makes the sealing block 25 and the sealing sleeve 27 fit tightly together. Thus, the sealing block 25 and the sealing sleeve 27 seal the puncture tube 20, thereby preventing gas from flowing back into the pleural cavity through the puncture tube 20. When the pressure inside the patient's pleural cavity reaches a safe range, the pressure inside the puncture tube 20 is insufficient to push the sealing block 25 upward, thus keeping the puncture tube 20 sealed and helping to keep the gas pressure inside the patient's pleural cavity stable.

[0044] like Figures 2-6As shown, a bonding component is provided on the lower side of the contact plate 15. The bonding component includes a mounting groove 30 at the bottom end of the contact plate 15. Multiple mounting grooves 30 are arranged in a ring array on the bottom surface of the contact plate 15. An elastic sleeve 31 is provided in each mounting groove 30. An anti-slip groove 32 is provided on the outer surface of the lower end of the elastic sleeve 31.

[0045] The upper end of the contact plate 15 is provided with a capsule 22, which is located inside the first sleeve 16 and the second sleeve 18. The capsule 22 is annular and surrounds the outside of the puncture tube 20. There is a gap between the capsule 22 and the puncture tube 20. A rotating plate 23 is fixedly connected to the upper end face of the capsule 22. The rotating plate 23 is annular and surrounds the top end of the puncture tube 20. The top end of the rotating plate 23 is rotatably connected to the bottom surface of the piston cylinder 11. The bottom end of the capsule 22 is connected to a connecting tube 33, and the bottom end of the connecting tube 33 is connected to the inside of the elastic sleeve 31.

[0046] By adopting the above technical solution, in order to avoid accidental damage to the patient's lungs due to displacement of the emergency device during emergency treatment, a fitting component is set up. The contact plate 15 is fixedly supported by the elastic sleeve 31 through the mounting groove 30. When the operator adjusts the contact plate 15 upward, the contact plate 15, together with the bottom wall of the piston cylinder 11, compresses the bladder 22. The bladder 22 is rotated and supported by the piston cylinder 11 through the rotating plate 23, thereby keeping the bladder 22 and the contact plate 15 relatively stationary. When the bladder 22 is compressed, the air inside it enters the elastic sleeve 31 through the connecting pipe 33. Under the action of gas pressure, the elastic sleeve 31 undergoes elastic deformation, thereby enabling... When the elastic sleeve 31 expands to the outside of the mounting groove 30 and the contact plate 15 is placed on the patient's skin surface, the lower surface of the elastic sleeve 31 will adhere to the patient's skin surface. The anti-slip groove 32 on the lower side of the elastic sleeve 31 can effectively increase the friction between the elastic sleeve 31 and the skin, thereby effectively improving the stability of the contact plate 15 during placement. At the same time, the elastic sleeve 31 can deform according to the curvature of the patient's skin surface, thus maintaining a tight fit with the patient's skin surface. This not only effectively improves the stability of the emergency device during operation, but also further reduces the risk of accidental injury to the patient, thereby improving the safety of the emergency device to a certain extent.

[0047] like Figure 4 and Figure 7As shown, a cleaning component is provided on the lower side of the contact plate 15. The cleaning component includes a liquid storage chamber 34 embedded in the inner side of the contact plate 15. An overflow hole 48 is provided at the lower end of the contact plate 15. The top end of the overflow hole 48 is connected to the liquid storage chamber 34. The number of overflow holes 48 is several groups and they are arranged in a ring array, that is, several overflow holes 48 are arranged around the outside of the puncture tube 20. A sliding groove 35 is embedded in the inner wall of the bottom of the overflow hole 48. A sliding rod 36 is slidably connected to the inner side of the sliding groove 35.

[0048] A top rod 38 is fixedly connected to the upper end of the slide rod 36, and a contact block 39 is fixedly connected to the lower end of the slide rod 36. The outer surface of the contact block 39 is arc-shaped. A sealing membrane 37 is fixedly connected to the inner surface of the overflow hole 48. The sealing membrane 37 is positioned above the top rod 38 and seals the connection between the liquid storage chamber 34 and the overflow hole 48. An appropriate amount of disinfectant is added inside the liquid storage chamber 34.

[0049] By adopting the above technical solution, a cleaning component is set up during the puncture process to reduce the probability of infection at the puncture site. When the contact plate 15 is placed on the patient's skin surface, the patient's skin will contact the lower surface of the contact block 39 and push the contact block 39 upward. During the movement of the contact block 39, the slide rod 36 will move synchronously in the slide groove 35. The slide groove 35 inside the overflow hole 48 can guide the slide rod 36 to a certain extent, so that the slide rod 36 moves more smoothly. During the movement of the slide rod 36, the top rod 38 will move synchronously. When the top rod 38 moves upward, it will puncture the sealing membrane 37. At this time, the disinfectant inside the liquid storage chamber 34 will flow to the patient's skin surface through the overflow hole 48. There are several groups of overflow holes 48, which are distributed in a ring around the puncture tube 20. The discharge of disinfectant can disinfect the patient's puncture site, thereby effectively reducing the risk of infection at the patient's puncture site and further improving the safety of the emergency device during use.

[0050] like Figure 4 and Figure 8 As shown, a backflow assembly is provided inside the guide pipe 14. The backflow assembly includes a circular first partition 40 fixedly connected to the inner wall of the guide pipe 14. The outer diameter of the first partition 40 is adapted to the inner diameter of the guide pipe 14. A first through hole 41 is opened in the middle of the first partition 40. A guide groove 42 is embedded in the inner wall of the guide pipe 14. The guide groove 42 is located on one side of the first partition 40 and on the side near the opening of the guide pipe 14 that connects to the outside. A guide block 44 is slidably connected inside the guide groove 42.

[0051] The inner surface of the guide tube 14 is slidably connected to a second partition 43. The bottom end of the outer surface of the second partition 43 is fixedly connected to a guide block 44. The second partition 43 is provided with a second through hole 47. The number of the second through holes 47 is several groups and they are distributed in a ring array on the second partition 43. The inner surface of the guide tube 14 is fixedly connected to a mounting plate 46. The mounting plate 46 is close to the side of the guide tube 14 that connects to the outside. The mounting plate 46 is ring-shaped. The outer diameter of the mounting plate 46 is adapted to the inner diameter of the guide tube 14. The mounting plate 46 and the first partition 40 are respectively located on both sides of the second partition 43. A spring 45 is connected between the mounting plate 46 and the second partition 43.

[0052] By adopting the above technical solution, when the piston plate 21 moves downward inside the piston cylinder 11, the piston plate 21 will compress the gas inside the piston cylinder 11. At this time, the gas enters the guide tube 14 under pressure, and then the gas will pass through the first through hole 41 on the surface of the first partition 40 and push the second partition 43, causing the second partition 43 to slide inside the guide tube 14. The guide block 44 inside the guide tube 14, together with the guide groove 42, can guide the movement of the second partition 43, so that the second partition 43 can slide linearly, thereby causing the first partition 40 and the second partition 43 to disengage. At this time, the gas will be discharged to the outside of the guide tube 14 through the second through hole 47 on the surface of the second partition 43. During the movement, the second partition 43 will cooperate with the mounting plate 46 to compress the spring 45. When the gas inside the piston cylinder 11 is completely discharged, The second partition 43 moves in the opposite direction under the elastic force of the spring 45, thereby keeping the surface of the second partition 43 in contact with the surface of the first partition 40. Since the first through hole 41 and the second through hole 47 are staggered, the gas can be prevented from continuing to flow when the first partition 40 and the second partition 43 are in contact, thus ensuring that the guide tube 14 maintains good sealing. When the gas outside the guide tube 14 flows back into the piston cylinder 11, the second partition 43 will fit more tightly with the first partition 40, which can not only prevent the backflow of gas, but also effectively reduce the risk of dust in the external environment entering the patient's chest cavity. The elastic force applied to the second partition 43 by the spring 45 will push the second partition 43 only after the pressure inside the guide tube 14 reaches a certain range, thus maintaining the pressure inside the piston cylinder 11 within an appropriate range while expelling the gas.

[0053] The workflow of the technical solution provided by this invention is as follows:

[0054] In use, the puncture tube 20 is inserted into the patient's pleural cavity. Gas pressure is used to expel air from the pleural cavity through the puncture tube 20, thus releasing pressure within the pleural cavity. The second sleeve 18 is threadedly connected to the first sleeve 16. As the second sleeve 18 rotates, the contact plate 15 moves along the axis of the first sleeve 16. During this movement, the distance between the lower surface of the contact plate 15 and the lower end of the puncture tube 20 changes, allowing adjustment of the length of the puncture tube 20 inserted into the pleural cavity. Under the tension of the traction bar 29 and the weight of the sealing block 25, the sealing block 25 maintains a tight seal with the surface of the sealing sleeve 27. This seal, through the interaction of the sealing block 25 and the sealing sleeve 27, prevents gas from passing through. The puncture tube 20 flows back into the chest cavity, and when the pressure inside the patient's chest cavity reaches a safe range, the elastic sleeve 31 can deform according to the curvature of the patient's skin surface, thus maintaining a tight fit with the patient's skin surface at all times, which can effectively improve the stability of the emergency device during operation. When the push rod 38 moves upward, it will puncture the sealing membrane 37, so that the disinfectant inside the reservoir 34 will flow to the patient's skin surface through the overflow hole 48. The discharge of disinfectant can disinfect the puncture site. The elastic force applied to the second partition 43 by the spring 45 will push the second partition 43 only after the pressure inside the guide tube 14 reaches a certain range, so that the pressure inside the piston cylinder 11 can be maintained within an appropriate range while expelling gas.

[0055] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
