Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a closed chest drainage device. Background Art

[0002] The human chest cavity is a negative pressure cavity. In clinical medicine, after the chest cavity of a patient undergoing cardiothoracic surgery or chest trauma treatment is opened and sutured, the negative pressure in the chest cavity disappears. Therefore, medical staff need to drain the blood, fluid, and some air in the patient's chest cavity to restore the air pressure in the chest cavity to its original state below atmospheric pressure. Generally speaking, in order to drain the gas or fluid in the patient's chest cavity, medical staff will use a chest drainage system to drain the gas or fluid in the chest cavity into a drainage bottle. The closed chest drainage bottle is commonly used in clinical practice. When in use, medical staff will insert the upper end of the chest drainage tube into the patient's chest cavity.

[0003] CN215082923U discloses a closed chest drainage device. By setting a detachable tube between the drainage tube and the drainage bottle, it is easy to replace the drainage bottle in the case of excessive fluid accumulation. The replacement is simple and convenient, avoiding the patient's discomfort caused by multiple punctures; by setting a three-way valve, the flushing and drainage are integrated, avoiding the pain caused by puncturing multiple tubes.

[0004] The drainage tube and puncture tube in the drainage device do not have a structure that can fix them. Therefore, when the puncture tube is implanted in the patient's chest cavity for drainage, the drainage tube and the puncture tube will be displaced due to touch or the patient's own movement, thereby causing certain damage to the patient's chest cavity.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] In order to solve the above technical problem that the drainage tube and the puncture tube in the drainage device do not have a structure to fix them, so when the puncture tube is implanted in the patient's chest cavity for drainage, the drainage tube and the puncture tube will be displaced due to contact or the patient's own movement, thereby causing certain damage to the patient's chest cavity, the basic concept of the technical solution adopted by the present invention is:

[0007] A closed chest drainage device comprises a collecting bottle;

[0008] The negative pressure pipe is connected to the top of the collecting bottle, and the top of the collecting bottle is provided with a fixed adjustment mechanism, and the fixed adjustment mechanism is provided with a cut-off mechanism. The fixed adjustment mechanism includes a drainage pipe connected to the top of the collecting bottle:

[0009] The outer wall of the fixing frame is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to a slider, and one end of the slider is fixedly connected to the support rod away from the sliding groove, and one end of the support rod is fixedly connected to the top block away from the slider.

[0010] As a preferred embodiment of the present invention, the cut-off mechanism includes a sliding frame movably arranged on the outer wall of the drainage tube, the outer wall of the sliding frame is provided with a first groove, the inner wall of the first groove is rotatably connected to a rotating shaft, the outer wall of the rotating shaft is fixedly connected to a rotating plate, the outer wall of the rotating plate is fixedly connected to a first magnet, the outer wall of the rotating plate is fixedly connected to a clamping block on one side of the first magnet, the outer wall of the sliding frame on the opposite side of the first groove is provided with a second groove, the inner wall of the second groove is fixedly connected to the second magnet, and the inner wall of the sliding frame is fixedly connected to an auxiliary clamping block.

[0011] As a preferred embodiment of the present invention, there are two support rods, and the support rods are distributed on the left and right outer walls of the top block in a bilaterally symmetrical structure.

[0012] As a preferred embodiment of the present invention, a slot is provided on the outer wall of the other splint, and the outer wall of the supporting insert is movably connected to the inner wall of the slot.

[0013] As a preferred embodiment of the present invention, the outer wall of the force-bearing block away from the connecting rod is provided with an inclined surface, and the left and right sides of the top block are respectively provided with inclined surfaces, and the inclined surfaces provided on the outer walls of the two blocks fit closely together.

[0014] As a preferred embodiment of the present invention, the auxiliary clamping block and the clamping block are both in a semicircular arc shape.

[0015] As a preferred embodiment of the present invention, the inner wall of the second groove formed on the outer wall of the sliding frame fits snugly with the outer wall of the rotating plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] After the limit is adhered, the top block can be released, and the spring at this time rebounds and resets to push the clamping plates on both sides close to each other and then clamped on the outer wall of the stressed jacket, so that the drainage tube can be limited, preventing the drainage tube from moving during the drainage process and causing damage to the patient's chest cavity.

[0018] The utility model firstly moves the rotating plate to rotate through the rotating shaft, and the rotating plate at this time will drive the clamping block to rotate, so that the clamping block contacts the outer wall of the drainage tube, and then continues to rotate downward, so that the clamping block squeezes the outer wall of the drainage tube, so that the bottom end of the drainage tube will be limited by the auxiliary clamping block, thereby being squeezed up and down, and the drainage tube is cut off. Then the collecting bottle is separated from the drainage tube and replaced with a new collecting bottle. After the extrusion of the drainage tube is completed, the first magnet and the second magnet will be magnetically attracted to each other, thereby limiting the rotating plate and the clamping block. After the replacement is completed, the rotating plate can be moved upward to make the first magnet and the second magnet lose their magnetic attraction, and the cut-off of the drainage tube is released, and the drainage operation can be resumed.

[0019] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

One end of the spring 313 is fixedly connected to the inner wall of the sliding hole, and the spring 313 is away from the fixed The other end of the inner wall of the frame 312 is fixedly connected to a sliding post 314, and the end of the sliding post 314 away from the spring 313 is fixedly connected to a splint 315, and one outer wall of the splint 315 is fixedly connected to a supporting plug plate 316, and the top of the sliding post 314 is fixedly connected to a connecting rod 317, and the end of the connecting rod 317 away from the sliding post 314 is fixedly connected to a force block 318, and a sliding groove 3112 is provided on the outer wall of the fixed frame 312, and a slider 3111 is slidably connected to the inner wall of the sliding groove 3112, and the end of the slider 3111 away from the sliding groove 3112 is fixedly connected to the support rod 3110, and the end of the support rod 3110 away from the slider 3111 is fixedly connected to the top block 319.

[0029] Furthermore, there are two support rods 3110 , which are distributed on the left and right outer walls of the top block 319 in a left-right symmetrical structure, thereby evenly supporting the left and right sides of the top block 319 and improving the stability of the top block 319 .

[0030] Furthermore, a slot is provided on the outer wall of the other clamping plate 315 , and the outer wall of the supporting inserting plate 316 is movably connected to the inner wall of the slot, thereby ensuring the relative movement stability between the two clamping plates 315 .

[0031] Furthermore, a slope is provided on the outer wall of the force-bearing block 318 away from the connecting rod 317, and a slope is provided on the left and right sides of the top block 319 respectively. The slopes provided on the outer walls of the two blocks fit together, so that the slopes of the two blocks can fit perfectly together, thereby enabling a smooth squeezing effect on the force-bearing block 318.

[0032] The cut-off mechanism 32 includes a sliding frame 321 movably arranged on the outer wall of the drainage tube 3114, and a first groove is provided on the outer wall of the sliding frame 321. The inner wall of the first groove is rotatably connected to the rotating shaft 322, and the outer wall of the rotating shaft 322 is fixedly connected to the rotating plate 323. The outer wall of the rotating plate 323 is fixedly connected to the first magnet 324, and the outer wall of the rotating plate 323 is fixedly connected to the clamping block 325 on one side of the first magnet 324. The outer wall of the sliding frame 321 on the opposite side of the first groove is provided with a second groove, and the inner wall of the second groove is fixedly connected to the second magnet 326. The inner wall of the sliding frame 321 is fixedly connected to the auxiliary clamping block 327.

[0033] Furthermore, the auxiliary clamping block 327 and the clamping block 325 are both in a semicircular arc shape, so that when the two are close to each other, they can clamp the drainage tube 3114, thereby cutting off the drainage tube 3114.

[0034] Furthermore, the inner wall of the second groove opened on the outer wall of the sliding frame 321 fits in with the outer wall of the rotating plate 323, so that the outer wall of the rotating plate 323 can be matched with the inner wall of the second groove, thereby limiting the rotating plate 323 to a certain extent, thereby improving the stability of the rotating plate 323.

[0035] The implementation principle of a chest closed drainage device of this embodiment is as follows: after the drainage tube 3114 is implanted into the patient's chest cavity, the position of the fixing frame 312 can be adjusted according to the length of the drainage tube 3114 implanted in the chest cavity of different patients. When adjusting, first press the top block 319 downward. At this time, the top block 319 will move downward to squeeze the force-bearing blocks 318 on the left and right sides. The squeezed force-bearing blocks 318 will move to the left and right sides, thereby driving the sliding column 314 to move. The movement of the sliding column 314 can drive the left and right splints 315 to move. At this time, the left and right splints 315 will move away from each other, thereby releasing the clamping limit of the force-bearing jacket 311. The fixing frame 312 can release the limit fixation, and at the same time, the spring 313 will be squeezed during the movement of the sliding column 314, and then the fixing frame 312 can be pulled to move on the outer wall of the force-bearing sleeve 311, so that the adhesive plate 3113 on one side of the fixing frame 312 is attached to the patient's chest skin, and the fixing frame 312 can be limited and fixed by the adhesive plate 3113. After the adhesive limit is achieved, the top block 319 can be released. At this time, the spring 313 rebounds and resets, pushing the splints 315 on both sides close to each other and then clamped on the outer wall of the force-bearing sleeve 311, so that the drainage tube 3114 can be limited to prevent the drainage tube 3114 from moving during the drainage process and causing damage to the patient's chest cavity.

[0036] When the accumulated liquid in the collecting bottle 1 is full and needs to be replaced, the rotating plate 323 is first toggled on the rotating shaft 322 to rotate. At this time, the rotating plate 323 will drive the clamping block 325 to rotate, so that the clamping block 325 contacts the outer wall of the drainage tube 3114, and then continues to rotate downward, so that the clamping block 325 squeezes the outer wall of the drainage tube 3114, so that the bottom end of the drainage tube 3114 will be limited by the auxiliary clamping block 327, thereby being squeezed up and down, 14 is used for the cut-off effect, and then the collecting bottle 1 and the drainage tube 3114 are separated and replaced with a new collecting bottle 1. After the drainage tube 3114 is squeezed, the first magnet 324 and the second magnet 326 will be magnetically attracted to each other, thereby limiting the rotating plate 323 and the clamping block 325. After the replacement is completed, the rotating plate 323 can be pushed upward to make the first magnet 324 and the second magnet 326 lose their magnetic attraction, and the cut-off of the drainage tube 3114 can be released to resume the drainage operation.
