Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to an integrated flushing and suction device for easily cleaning necrotic tissue. Background Technology
[0002] Currently, Chinese utility model patent "CN209285653U" discloses a device for removing necrotic tissue from burn wounds. It states that for patients with severe burns, medical staff need to use a scalpel to remove necrotic tissue from the burn site and then transplant new skin onto the removed area. However, due to the different burn locations and degrees, the traditional scalpels are single-piece designs and come in many types. When changing scalpels, medical staff need to find the corresponding scalpel before performing the necrotic tissue removal surgery, which is inconvenient for medical staff and reduces their work efficiency. The existing removal device has a single function and cannot collect the removed necrotic tissue, nor can it disinfect and clean the burn wound while removing it.
[0003] While the aforementioned device enables simultaneous removal and irrigation of necrotic tissue from the patient's wound, significantly improving the efficiency of wound cleaning, it still has the following shortcomings in practical use:
[0004] ①The main driving force of the above device in the cleaning process is a water pump. Although this method is relatively convenient, it has great limitations in use because it requires an external power source.
[0005] ②In addition, the above-mentioned device is relatively large in size, which makes it inconvenient for medical staff to carry during use, and thus cannot effectively assist medical staff in completing the rinsing work, reducing the efficiency of the rinsing work;
[0006] ③ At the same time, although the above-mentioned device also realizes the function of collecting waste liquid in the cleaning process, the waste liquid contains damaged tissue, and some larger damaged tissue is very easy to cause blockage during the collection process, which affects the overall efficiency of waste liquid and damaged tissue collection. Summary of the Invention

The suction cylinder is fixedly installed on the upper surface of the right end of the handle, and a screw cap is installed on the left end of the suction cylinder. A piston rod is adapted to be installed inside the suction cylinder. The piston rod and the suction cylinder form a piston cylinder structure. The left end of the piston rod extends to the outside of the left end of the screw cap and is fixedly connected to the follow-up slide rod. The right end of the suction cylinder is connected to the valve suction tube, and the valve suction tube is a one-way valve structure.

[0017] Preferably, the auxiliary chopping mechanism includes: a side shaft, a docking cylinder, a toothed disc, a toothed ring, a cutter head, and a baffle plate. The side shaft is fixedly connected to the front outer wall of the follower slide rod, and the docking cylinder is sleeved on the right end of the side shaft.

[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] (1) Medical staff hold the lower left end of the handle and apply pressure greater than the torsion spring shaft to the right end of the handle. The spring piston rod moves to the left, which will cause a negative pressure to be formed inside the right side of the flushing tube. Then, the cleaning solution inside the bottled cleaning solution is drawn into the right end of the flushing tube through the liquid guide tube and the outer tube. The flushing solution inside the flushing tube is finally sprayed out from the inside of the flushing hood to the right side. At this time, the flushing hood is aimed at the patient's wound, so that the patient's wound can be accurately flushed. Since the flushing solution is sprayed out under the action of the torsion spring shaft and the spring's rebound force, the flushing solution can maintain a certain flushing force during the spraying process. In this way, medical staff can repeatedly apply pressure and release pressure on the handle, so as to continuously and effectively flush the damaged tissue at the patient's wound.
[0020] (2) When the liquid level of the waste liquid reaches the lower end of the suction tube, as the spring piston rod inside the flushing tube moves back and forth with the pull rope, the spring piston rod will also drive the follower slide rod to move synchronously. This will suck the flushing waste liquid and wound tissue collected inside the flushing hood into the ring tube from the lower end of the suction tube and send it into the suction tube through the valve suction tube. Under the restriction of the valve suction tube, the waste liquid collected inside the suction tube can be prevented from flowing back. This allows the flushing waste liquid generated during the patient's flushing process to be collected and treated in a timely manner, thereby achieving the effect of flushing and suction in one step. This will also reduce the accumulation of waste liquid at the patient's wound and improve the efficiency of wound tissue cleaning.
[0021] (3) When using the bandage, it needs to be attached to the outer edge of the patient's wound. Since the bandage is made of soft rubber, after it is attached to the patient's skin, it can reduce the amount of wastewater generated during rinsing and thus improve the patient's experience during the rinsing process.
[0022] (4) This device can perform rinsing without the need for external power boosting components. The device is relatively small and compact in its overall structure. Medical staff can rinse the patient's wound simply by holding the handle. The operation is simple and convenient, which not only makes it easy for medical staff to use, but also improves the efficiency of medical staff in rinsing the patient's wound and necrotic tissue.
[0023] (5) When the toothed ring rotates, it will drive the cutter head inside the rinsing hood to rotate synchronously. This process is synchronized with the process of suctioning the waste liquid from the suction tube. Thus, under the rotating cutting action of the cutter head, larger necrotic tissues generated in the rinsing waste liquid can be broken and cut, which makes it easier for the suction tube to suck up the waste liquid and necrotic tissues from the wound. At the same time, it can also reduce the occurrence of blockage of necrotic tissues during the collection process. Attached Figure Description

[0051] Embodiment 3 of the present invention
[0052] Please refer to Figures 1 to 11 As shown,
[0053] The follow-up suction mechanism includes: a suction cylinder 31, a cap 32, a piston rod 33, a follow-up slide rod 34, a valve suction tube 35, a ring tube 36, and a suction tube 37. The suction cylinder 31 is fixedly installed on the upper right surface of the handle 1, and a cap 32 is installed on the left end of the suction cylinder 31. The left end of the suction cylinder 31 and the cap 32 are threaded together. The outer wall of the cap 32 is provided with anti-slip texture to facilitate the subsequent pouring of waste liquid. The piston rod 33 is fitted inside the suction cylinder 31. The piston rod 33 and the suction cylinder 31 form a piston cylinder structure. The left end of the piston rod 33 extends... A follower slide rod 34 is fixedly connected to the outside of the left end of the screw cap 32. The lower end of the follower slide rod 34 extends into the inside of the handle 1 and is fixedly connected to the outer wall of the left end of the spring piston rod 27. The lower end of the follower slide rod 34 is slidably connected to the handle 1. The right end of the suction cylinder 31 is connected to a valve suction tube 35. The right end of the valve suction tube 35 is connected to a ring tube 36. Suction tubes 37 are evenly installed on the right end of the ring tube 36. The ring tube 36 and the suction tubes 37 are interconnected. The lower end of the suction tubes 37 extends into the inside of the rinsing hood 211. The number of suction tubes 37 is not less than six.
[0054] The complete usage steps and working principle of this invention are as follows:
[0055] First, when using this device, medical personnel can connect the bottled cleaning solution for rinsing wound tissue to the outer tube 11 at the lower left end of the handle 1, and carry the bottled cleaning solution with them. Then, the medical personnel align the rinsing cover 211 with the patient's wound and ensure that the patch 212 fits against the skin at the outer edge of the wound. Note: The size of the outer tube 11 can be selected according to the size of the patient's wound. Then, the medical personnel hold the lower left end of the handle 1 and apply pressure greater than the torque of the torsion spring shaft 22 to the right end of the button 21, causing the button 21 to rotate around the torsion spring shaft 22. When the button 21 rotates, it causes the eccentric strip 23 to drive the follower plate 24 to rotate around the rotating shaft 25. The rotating shaft 25 then drives the pull rope 26 to be stressed, thereby pulling the spring piston rod 27 to slide to the left inside the rinsing cylinder 28. The suction provided by the leftward movement of the spring piston rod 27 causes the rinsing cylinder 28 to be pushed forward. A negative pressure is formed inside the right side of the 8, which then draws the cleaning solution from the bottled cleaning solution into the right end of the rinsing cylinder 28 through the liquid guide tube 29 and the outer tube 11. Then, the medical staff releases the pressure on the handle 21. At this time, under the combined action of the rebound force of the torsion spring shaft 22 and the rebound force of the spring sleeved on the outside of the spring piston rod 27, the spring piston rod 27 is forced to squeeze the inside of the right end of the rinsing cylinder 28. This causes the disinfectant drawn into the right end of the rinsing cylinder 28 to be continuously sent out to the right end from the valve nozzle 210. Finally, the rinsing solution is sprayed out to the right from the inside of the rinsing hood 211. At this time, the rinsing hood 211 is exactly aligned with the patient's wound, so that the wound can be accurately rinsed. Since the rinsing solution is sprayed out under the action of the rebound force of the torsion spring shaft 22 and the spring, the rinsing solution can maintain a certain rinsing force during the spraying process. In this way, the medical staff can repeatedly apply pressure and release pressure on the handle 21, so as to continuously and effectively rinse the damaged tissue at the patient's wound.
[0056] Furthermore, medical staff can easily rinse the patient's wound by holding the handle 1, and the operation process is simple and convenient. It is not only easy for medical staff to use, but also improves the efficiency of medical staff in rinsing the patient's wound and necrotic tissue. At the same time, when using the patch 212, it needs to be attached to the outer edge of the patient's wound. Since the patch 212 is made of soft rubber, it can reduce the amount of wastewater generated during rinsing when it is attached to the patient's skin, thereby improving the patient's experience during the rinsing process.
[0057] Simultaneously, as medical staff continue rinsing, waste fluid and damaged tissue from the wound gradually accumulate inside the rinsing hood 211. When the waste fluid level reaches the lower end of the suction tube 37, the spring piston rod 27 inside the rinsing cylinder 28 reciprocates left and right due to the pull rope 26. This spring piston rod 27 also drives the follower slide rod 34 to move synchronously. When the follower slide rod 34 moves, it drives the piston rod 33 to move synchronously inside the suction cylinder 31. Under the action of the valve suction tube 35 (a one-way valve structure), when the piston rod 33 moves to the left, the waste fluid and damaged tissue collected inside the rinsing hood 211 are expelled through the suction tube 37. The suction tube 36 is drawn into the suction cylinder 31 through the valve suction tube 35. When the pressure of the waste fluid collected inside the suction cylinder 31 is insufficient to move the piston rod 33 to the right again, medical staff can turn the cap 32 and pour out the waste fluid and necrotic tissue collected inside the suction cylinder 31 so that the suction cylinder 31 can continue to be used normally. When the piston rod 33 moves to the right, the valve suction tube 35 restricts the backflow of the waste fluid collected inside the suction cylinder 31. This allows the waste fluid generated during the patient's flushing process to be collected and treated in a timely manner, thus achieving the effect of flushing and suction in one step. This also reduces the accumulation of waste fluid at the patient's wound and improves the efficiency of wound and necrotic tissue cleaning.
[0058] Furthermore, when the follower slide bar 34 moves left and right, it will also drive the side shaft 41 to move synchronously. When the side shaft 41 moves, since the right end of the side shaft 41 and the docking cylinder 42 form a ball screw structure, the docking cylinder 42 will rotate during the movement of the side shaft 41. In turn, the docking cylinder 42 will drive the toothed disc 43 to rotate. When the toothed disc 43 rotates, it will cause the toothed ring 44 that meshes with it to rotate. When the toothed ring 44 rotates, it will drive the cutter head 45 located inside the rinsing hood 211 to rotate synchronously. This process is synchronized with the process of the suction tube 31 sucking up the waste liquid. Thus, under the rotational cutting action of the cutter head 45, larger bad tissues generated in the rinsing waste liquid can be broken and cut, which makes it easier for the suction tube 37 to suck up the waste liquid and wound bad tissues. At the same time, it can also reduce the situation of bad tissues clogging during the collection process.
[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
