Description

Technical Field

[0001] The utility model relates to the technical field of bronchoscopic examination auxiliary instruments, in particular to a connecting device for alveolar lavage. Background Art

[0002] Alveolar lavage refers to a technique developed on the basis of bronchoscopy. It uses a bronchoscope to inject normal saline into the bronchoalveoli and then suck it out, collecting the effective fluid on the alveolar surface for laboratory examination. When performing lavage, the bronchoscope probe needs to be inserted into the patient's trachea and inserted to the target position according to the image. Then, the water injection tube is inserted into the biopsy port of the bronchoscope, and the water injection tube is connected to the syringe to inject the lavage fluid into the patient's body, and then the extraction is performed. However, in actual operation, there are the following defects: 1. Because the water injection tube inserted into the biopsy port is smaller than the diameter of the biopsy port, and the biopsy port is The negative pressure suction port is connected to the insertion part inserted into the patient's body. Therefore, after water injection, the water injection tube needs to be quickly pulled out from the biopsy port and the biopsy port is pressed with the thumb. Then, the negative pressure connection switch on the bronchoscope is pressed, and the negative pressure draws out the irrigation fluid injected into the patient's body. Then, the water injection tube is reinserted into the biopsy port to inject water again. This process is repeated, and the operation is cumbersome, time-consuming and labor-intensive. 2. Since the biopsy port is only located on one side of the bronchoscope, when the operating physician rotates the bronchus according to the examination needs, the medical staff responsible for injecting water with the syringe also needs to quickly move to the other side of the operating physician, which is inconvenient. Utility Model Content

[0003] In view of the above situation, in order to make up for the deficiencies of the prior art, the purpose of the utility model is to provide a connection device for alveolar lavage, which effectively solves the problem of cumbersome operation, time-consuming and labor-intensive operation when performing alveolar lavage on patients.

[0004] The technical solution is that the utility model includes a left-right axial hose, a left-right axial baffle plate is slidably connected to the hose, an annular blocking block is coaxially provided at the left end of the baffle plate, sliding grooves are respectively provided at the upper and lower ends of the blocking block, a limit block is slidably connected in the sliding groove, the opposite ends of the two limit blocks are arc surfaces, left-right penetrating movable grooves are respectively provided on the upper and lower sides of the right end of the baffle plate, an L-shaped pressure rod is slidably connected in the movable groove and fixed to the limit block on the corresponding side, and an adapter is provided at the right end of the hose.

[0011] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0012] Depend on Figures 1 to 5 It is given, including a left and right axial hose 1, a left and right axial baffle plate 2 is slidably connected to the hose 1, an annular blocking block 3 is coaxially provided at the left end of the baffle plate 2, and a slide groove 4 is respectively provided at the upper and lower ends of the blocking block 3, a limit block 5 is slidably connected in the slide groove 4, and the opposite ends of the two limit blocks 5 are arc surfaces respectively, and left and right through movable grooves 6 are respectively provided on the upper and lower sides of the right end of the baffle plate 2, an L-shaped pressure rod 7 is slidably connected in the movable groove 6 and fixed to the limit block 5 on the corresponding side, and an adapter 8 is provided at the right end of the hose 1.

[0013] In order to facilitate pressing the pressure rod 7, a pressure plate 9 is provided at the right end of the pressure plate 9.

[0014] In order to facilitate the resetting of the limit block 5 , the opposite ends of the two limit blocks 5 are connected to the blocking block 3 via compression springs 10 .

[0015] In order to facilitate sealing of the adapter 8, a blocking column 11 is slidably connected to the adapter 8 in the front-rear axial direction, and a connecting hole 12 is opened on the blocking column 11 and is located behind the adapter 8 and in the left-right axial direction.

[0016] In order to facilitate pressing the blocking column 11, a pressing plate 13 is provided at the front and rear ends of the blocking column 11 respectively.

[0017] In order to increase the sealing performance, a rubber layer is provided on the outer edge surface of the blocking block 3 .

[0018] When the utility model is in use, the bronchoscope is first inserted into the patient's trachea, and then the left end of the hose 1 is inserted into the biopsy port on the bronchoscope, and then the two pressure plates 9 are pressed toward the middle. The two pressure plates 9 slide relative to each other and drive the two limit blocks 5 to move toward the middle through the pressure rod 7. The two limit blocks 5 move toward the middle and squeeze the compression spring 10 inward. After moving a certain distance toward the middle, the two limit blocks 5 slide into the slide groove 4 on the corresponding side, and then the blocking block 3 is inserted into the biopsy hole. At this time, the outer surface of the blocking block 3 contacts the biopsy port, and the pressure plate 9 is released. Due to the outward restoring force of the compression spring 10, the two limit blocks 5 are driven to slide back to each other. After sliding back to each other for a certain distance, the two limit blocks 5 extend out of the slide groove 4 and contact the inner wall of the biopsy port and are pressed and fixed. At this time, the blocking block 3 and the biopsy port are fixed and limited to prevent the blocking block 3 from falling off from the biopsy port during the irrigation process. At this time, the baffle plate 2 also blocks the biopsy port;

[0019] Then connect the adapter 8 to the syringe, and then press the push plate 13 forward, the push plate 13 drives the blocking column 11 to move forward, and the blocking column 11 drives the connecting hole 12 thereon to move forward. After moving forward for a distance, the connecting hole 12 is connected with the adapter 8 and the hose 1. At this time, when it is observed that alveolar lavage is needed, the medical staff pushes the syringe, injects the lavage fluid in the syringe into the biopsy port through the hose 1, and then injects it into the patient's body through the biopsy port. After the injection is completed, the push plate 13 is quickly pushed backward, and the push plate 13 is pushed backward. The blocking column 11 is driven to slide backward to the initial position. At this time, the blocking column 11 blocks the adapter 8 again. At this time, the biopsy port is completely disconnected from the outside world. Then, the connecting switch with the negative pressure device can be pressed to connect the negative pressure device with the bronchoscope. The negative pressure quickly sucks out the irrigation fluid injected into the patient's body. After sucking out, the connecting switch is released to disconnect the negative pressure device from the bronchoscope. At this time, stop suction, and then press the pressing plate 13 forward again to connect the connecting hole 12 again. At this time, push irrigation can be performed again.

[0020] Compared with the prior art, the beneficial effects of the utility model are: the hose, adapter, blocking block, etc. can realize fast and convenient alveolar lavage for patients under bronchoscope. After each push lavage, there is no need to pull out the hose from the biopsy port and seal it. Only the button needs to be pushed to quickly perform negative pressure extraction, which saves time and effort and has a high lavage fluid recovery rate. At the same time, when the bronchoscope operator rotates the bronchoscope, the syringe pusher does not need to move with it, and the operation is simple. This structure is simple, the concept is novel, it is easy to use, and it is practical.
