as shown in fig. 12, the iodophor cap unused for the new unpackaging comprises an iodophor cap 9 and a pull-tab cap 10 which are fastened to each other, and the inside of the iodophor cap 9 is provided with an internal thread;
as shown in fig. 13, the newly unpacked and unused peritoneal dialysis solution bag 8 comprises a peritoneal dialysis solution bag connector 805, a solution bag 801, a solution bag conduit 802, a waste solution bag 803, a waste solution bag conduit 803, and a pull ring cap 806, wherein the solution bag 801 is filled with peritoneal dialysis solution, the waste solution bag 803 is an empty bag, the pull ring cap 806 is fastened on the peritoneal dialysis solution bag connector 805, and internal threads are arranged inside the peritoneal dialysis solution bag connector 805;
as shown in fig. 14, the front end of the external short tube 7 of the human body is provided with a first external thread 701 and a second external thread 702 with different diameters, which are dark blue, and the first external thread 701 can be screwed with the connector 805 of the peritoneal dialysis solution bag; the second external thread 702 can be screwed with the iodophor cap 9, and a part of the human body catheter 703 is embedded in the abdominal cavity of the human body through operation.
With reference to fig. 3 and 5, when the upper lid 1 is opened and closed: the first collision block 101 and the second collision block 102 are irregular in shape, and can push the first collision column 408 and the second collision column 409 to move transversely when rotating; when the upper cover 1 is in a closed state (0 degree) to a fully opened state (90 degrees), the upper cover 1 rotates anticlockwise by taking the axes of the second striking block fixing seat 308 and the first striking block fixing seat 309 as rotating shafts, the first striking block 101 and the second striking block 102 rotate anticlockwise along with the upper cover 1, under the action of the elastic force of the rack spring 407, the rack push rod 405 is pushed to move leftwards, and under the action of force conduction, the linkage push rod 406, the first striking column 408 and the second striking column 409 move leftwards and transversely; because the rack push rod 405 is meshed and connected with the teeth on the rotating sleeve 401, the rack push rod 405 moves to drive the rotating sleeve 401 to rotate clockwise, and when the upper cover 1 is in a closed state (0 degree) to a fully opened state (90 degrees), the rotating sleeve 401 can rotate clockwise by 180 degrees; when the upper cover 1 is in a full-open state (90 degrees) to a closed state (0 degrees), the first collision block 101 and the second collision block 102 respectively push the first collision column 408 and the second collision column 409 to move transversely rightwards, and under the conduction action of force, the rack push rod 405 pushes the rotary sleeve 401 to rotate 180 degrees anticlockwise.
The principle of action between the rotating handle 2 and the rotating mechanism 5 is explained with reference to fig. 6, 7, 8, 9 and 10: the cam 202 is an eccentric wheel, the outer edge of the cam 202 is always in contact with the driven internal gear 509, and the cam 202 pushes the driven internal gear 509 to move linearly as the rotating handle 2 is pulled to rotate; the driven inner gear 509 has teeth therein, which are engaged with the teeth on the outside of the driving gear 510; when the handle 204 is pulled to a position close to the human body (the angle is 0 degrees), the handle is in an initial state, the driving gear 510 is inserted into the driven internal gear 509, and the teeth of the driven internal gear 509 are not in contact with the teeth of the driving gear 510; the handle 204 is pulled from 0 DEG to 45 DEG, the cam 202 pushes the driven internal gear 509 to move backwards linearly, and as the driven internal gear 509 is fastened with the driven rotating shaft 504 and the U-shaped rotating ring 501, the driven internal gear 509 moves and drives the driven rotating shaft 504 and the U-shaped rotating ring 501 to move backwards together; the U-shaped rotating ring 501 pulls the first rotating clamp 502 and the second rotating clamp 503 to move respectively through a first positioning pin 512 and a second positioning pin 513 which are fastened on the U-shaped rotating ring; the handle 204 is pulled from 45 degrees to 135 degrees, the driven internal gear 509 and the driving gear 510 are meshed together, the bevel gear one 203 is meshed with the bevel gear two 511 to rotate, the bevel gear two 511 drives the driving gear 510 and the driven internal gear 509 to rotate together through the driving rotating shaft 514, and the driven internal gear 509, the driven rotating shaft 504 and the U-shaped rotating ring 501 are fixed together to rotate together; from 135 degrees to 180 degrees, the driven internal gear (509) and the driving wheel (510) are not meshed any more, and the U-shaped rotating ring 501, the rotating clamp I502, the rotating clamp II 503, the driven rotating shaft 504 and the driven internal gear 509 move forwards under the pushing of the return spring 506; because the first rotating clamp 502 and the second rotating clamp 503 are respectively and rotatably connected to the first positioning pin 512 and the second positioning pin 513 and are not fastened together, when the driven rotating shaft 504 rotates, the first rotating clamp 502 and the second rotating clamp 503 cannot rotate, and after the driven rotating shaft 504 rotates 180 degrees, the first rotating clamp 502 and the second rotating clamp 503 are exchanged in position.
The principle of operation of the rotating handle mechanism 6 is explained with reference to fig. 4 and 11: when the hand support 609 is pulled outwards, the hand support 609 rotates by taking a position between the first hand support fixing seat 310 and the second hand support fixing seat 311 as a rotating shaft, the first torsion bar 601 and the second torsion bar 602 tilt up, the first pipe clamp push rod 603 and the second pipe clamp push rod 606 on the first torsion bar 601 and the second torsion bar 602 move upwards and are ejected out of holes in the first rotating clamp 502 and the second rotating clamp 503, the hand support is played back, the first torsion bar 601 and the second torsion bar 602 return, and the first pipe clamp push rod 603 and the second pipe clamp push rod 606 return under the action of a spring;
the working principle of the invention is further combined with specific medical practice as follows:
at present, peritoneal dialysis patients can connect an external short tube 7 of a human body at an abdominal cavity part by means of surgical operation, the external short tube of the human body is replaced once in half a year under the general condition, and when dialysis treatment is not carried out, an iodophor cap is required to be connected at an outlet of the external short tube of the human body to protect the outlet. When dialysis treatment is needed, the liquid medicine bag 801 of the peritoneal dialysis solution bag 8 needs to be hung at a high position, the waste liquid bag 803 is placed at a low position (generally on the ground), then the pull ring cap 806 at the position of the peritoneal dialysis solution bag connector 805 and the iodophor cap at the outlet of the external short tube of the human body are respectively taken down by hands, the peritoneal dialysis solution bag connector 805 and the external thread I701 of the external short tube of the human body are screwed together, the switch of the external short tube of the human body is opened, waste liquid in the abdominal cavity of the human body flows into the liquid medicine bag, the waste liquid bag conduit 804 is clamped by the blue clamp after the waste liquid is completely discharged, then the outlet plug of the liquid medicine bag is broken, the dialysis solution flows into the abdominal cavity of the human body, the liquid medicine is completely injected, the switch of the external short tube of the human body is closed, the peritoneal dialysis solution bag connector 805 and the external thread I701 of the external short tube of the human body are separated, a new iodophor cap 9 is taken, the pull ring cap 10 on the iodophor cap 9 and the external thread II 702 of the human body are screwed together, and the peritoneal dialysis treatment is completed manually.
By using the invention, the connection of the iodophor cap 9 and the external thread two 702 of the external short pipe of the human body and the connection of the peritoneal dialysis solution bag joint 805 and the external thread one 701 of the external short pipe of the human body can be completed in the invention, thereby avoiding the pollution to the outlet of the external short pipe of the human body caused by the contact of hands and external air.
