Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of medical devices and relates to an external catheter room pressurized interventional surgery drip device. Background Art
[0002] In interventional surgery, it is usually necessary to deliver liquids or drugs into the patient's body through pressurized infusion to ensure the smooth progress of the operation.
[0003] When performing drip infusion, it is usually necessary to infuse multiple bags of liquid into the patient's body one by one. The traditional method is for nurses to manually change the liquid medicine. Nursing staff engage in inefficient and repetitive work for a long time, which leads to occupational fatigue. Frequent manual liquid changes will also increase the risk of infection, and there is also the risk of changing the wrong medicine. In addition, it is necessary to pay attention to the dripping of the liquid medicine at any time.
[0004] In order to reduce the trouble of manual fluid replacement, electric fluid changers have emerged. After a bottle of liquid is infused, the electric fluid changer can automatically switch to another bottle of liquid to continue infusion, without the need for manual operation by medical staff or patients. Its working principle is usually to detect the remaining amount of liquid in the infusion bottle through a sensor. When the remaining amount reaches the set lower limit, the electric device in the device will be triggered to automatically close the current infusion path and open a new infusion path at the same time, thereby ensuring the continuity of the infusion process. However, the electric fluid changer itself is expensive, and its repair and maintenance requires professionals, which further increases the high cost of use.

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] like Figure 1-Figure 9 As shown, the technical solution adopted by the present invention is as follows: A catheter room external pressurized interventional surgery instillation device includes a bracket 1, a fixed plate 2, a guide column 5, a fixed block 7, a pressurizing assembly and a puncture assembly. The bracket 1 is fixedly connected to a first connecting rod 201, the first connecting rod 201 is fixedly connected to the fixed plate 2, and the guide column 5 is fixed on the upper end surface of the fixed plate 2. A plurality of T-shaped guide grooves 6 are provided on the guide column 5, the T-shaped guide grooves 6 are vertically arranged, and the plurality of T-shaped guide grooves 6 are evenly distributed around the circumference of the axis of the guide column 5. A fixed block 7 is provided in each T-shaped guide groove 6 for limiting sliding. The fixed block 7 is in an I-shape as a whole. A receiving groove 701 for placing a liquid medicine bag 8 is provided on the fixed block 7.
[0019] Each fixed block 7 is slidably provided with a pressurizing component, such as Figure 8As shown, in this embodiment, the pressure components are all located at the front side of the corresponding fixed block 7 in the counterclockwise direction. The pressure components include a clamping plate 9 and a sliding rod 10. The clamping plate 9 is slidably arranged in the receiving groove 701. A sliding hole adapted to the sliding rod 10 is provided on one side of the fixed block 7. One end of the sliding rod 10 extends through the sliding hole into the receiving groove 701 and is fixedly connected to the clamping plate 9. The sliding rod 10 is fixedly connected with a spring 15, and the spring 15 is fixedly connected to one side of the fixed block 7. The spring 15 is in a stretched state. The medicine liquid bag 8 is placed in the receiving groove 701, and the clamping plate 9 squeezes the medicine liquid bag 8. As the liquid in the medicine liquid bag 8 flows out, the sliding rod 10 slides into the receiving groove 701, thereby continuously squeezing the medicine liquid bag 8.
[0020] One end of the spring 15 located outside the receiving groove 701 is rotatably connected to the baffle 16 via a rotating shaft, and the rotating shaft is located between the upper side of the sliding rod 10 and the upper side of the baffle 16. A torsion spring is sleeved on the rotating shaft, and the torsion spring is fixedly connected between the sliding rod 10 and the baffle 16. Under the action of the torsion spring, when the end surface of the baffle 16 and the end surface of the sliding rod 10 are in contact, the baffle 16 cannot rotate downward relative to the sliding rod 10.
[0021] like Figure 1 , Figure 2 As shown, between two adjacent fixed blocks 7, the sliding rod 10 is slidably set on the fixed block 7 on the left, and the baffle 16 cooperates with the fixed block 7 on the right. The baffle 16 is above the lower side wing of the fixed block 7 on the right, and the width of the upper flange of the fixed block 7 is smaller than the width of the lower flange. Between the two adjacent fixed blocks 7, the fixed block 7 on the right is pulled upward. When the fixed block 7 contacts the baffle 16, the baffle 16 flips upward. After the fixed block 7 passes over the baffle 16, the baffle 16 flips downward under the action of the torsion spring and rests on the sliding rod 10 and cannot continue to rotate downward. Then release the fixed block 7, and the fixed block 7 slides downward and falls on the baffle 16. It should be noted that, among the two adjacent fixed blocks 7, when the fixed block 7 on the left moves upward, since the width of the upper flange of the fixed block 7 is smaller than the width of the flange, the upper flange of the fixed block 7 on the right will not hinder the baffle 16. Then, multiple fixing blocks 7 are lifted up in turn in the counterclockwise direction, and the fixing blocks 7 are placed on the corresponding baffles 16, and then multiple fixing blocks 7 are raised in turn in the counterclockwise direction. The fixing block 7 at the highest end is adjacent to the fixing block 7 at the lowest end, and the fixing block 7 at the lowest end abuts against the fixing plate 2, and the other fixing blocks 7 abut against the corresponding baffles 16.
[0022] The lower end surface of the fixed plate 2 is slidably connected to the support plate 3. Specifically, a sliding sleeve 18 is fixed to the lower end of the first connecting rod 201, and the support plate 3 is fixedly connected to the second connecting rod. A sliding column 19 is fixed to the second connecting rod, and the sliding column 19 is slidably inserted into the sliding sleeve 18. The first connecting rod 201 is rotatably connected to the threaded rod 4, and the threaded rod 4 is threadedly connected to the second connecting rod.
[0023] The support plate 3 is semicircular in shape. The puncture assembly is placed on the support plate 3.
[0024] The puncture assembly includes an annular tube 13, a second puncture needle 14 and a first puncture needle 12. The annular tube 13 is placed on the support plate 3. The annular tube 13 is a hard tube. A plurality of second puncture needles 14 are evenly distributed on the circumference of the annular tube 13. The second puncture needles 14 are fixed on the annular tube 13. The second puncture needles 14 are connected to the annular tube 13, and the needle tip of the second puncture needle 14 is vertically upward. The annular tube 13 is connected to the first puncture needle 12 through a hose, and the first puncture needle 12 is inserted into the patient's body. A plurality of first sockets cooperating with the second puncture needles 14 are provided on the fixed plate 2. The plurality of second puncture needles 14 correspond one-to-one to the plurality of first sockets, and the plurality of first sockets correspond one-to-one to the plurality of fixed blocks 7. The bottom end of the fixed block 7 is provided with a second socket 17 opposite to the corresponding first socket, and the second socket 17 is adapted to the second puncture needle 14. The second puncture needle 14 extends into the receiving groove 701 through the first insertion hole and the second insertion hole 17, and pierces into the drug bag 8. The drug in the drug bag 8 flows into the annular tube 13 through the second puncture needle 14, and flows into the patient's body through the first puncture needle 12.
[0025] The second puncture needle 14 is covered with a protective sleeve 11, which has a protective effect on the second puncture needle 14. When the second puncture needle 14 enters the second insertion hole 17, the protective sleeve 11 abuts against the lower end surface of the fixing block 7. The second puncture needle 14 pierces the protective sleeve 11 and extends into the second insertion hole 17. The protective sleeve 11 seals the second insertion hole 17 to prevent the drug solution from flowing out through the second insertion hole 17. The puncture assembly is a disposable item.
[0026] Working principle: Initially, Figure 1 As shown, the plurality of fixing blocks 7 are all against the upper end surface of the fixing plate 2. The plurality of drug bags 8 are sequentially placed into the plurality of receiving grooves 701. When placing the drug bags 8, the sliding rod 10 is pulled outwards so that the drug bags 8 are located on the side of the clamping plate 9 away from the sliding rod 10, and then the sliding rod 10 is released so that the clamping plate 9 is against the drug bags 8.
[0027] Then, one of the fixed blocks 7 is moved upward. When the lower side of the fixed block 7 contacts the corresponding baffle 16, the baffle 16 rotates around the rotation axis, so that the fixed block 7 passes over the baffle 16 smoothly. After the fixed block 7 passes over the baffle 16, the baffle 16 rotates downward under the action of the torsion spring until it abuts against the sliding rod 10. Then, the fixed block 7 is released, and the fixed block 7 slides downward until it abuts against the baffle 16, and the baffle 16 supports the fixed block 7. Then, multiple fixed blocks 7 are moved upward in turn in a counterclockwise direction, and the fixed blocks 7 are above the corresponding baffle 16, and then multiple fixed blocks 7 are raised in turn in a counterclockwise direction. The fixed block 7 at the highest end is adjacent to the fixed block 7 at the lowest end, and the fixed block 7 at the lowest end abuts against the fixed plate 2.
[0028] Then the annular tube 13 is placed on the support plate 3, which is semicircular, so the annular tube 13 can be easily placed on the support plate 3. The second puncture needle 14 is placed directly below the corresponding first plug hole. Then the threaded rod 4 is rotated to gradually bring the support plate 3 closer to the fixed plate 2, and the annular tube 13 and the second puncture needle 14 gradually move upward, and the second puncture needle 14 and the protective sleeve 11 pass through the corresponding first plug hole and extend above the fixed plate 2.
[0029] When the second puncture needle 14 extends to the top of the fixing plate 2, the second puncture needle 14 corresponding to the fixing block 7 abutting against the fixing plate 2 passes through the second insertion hole 17 and extends into the receiving groove 701 and pierces into the medicine bag 8. The liquid in the medicine bag 8 enters the annular tube 13 through the second puncture needle 14, and flows into the patient's body through the hose and the first puncture needle 12.
[0030] As the medicine in the medicine bag 8 gradually decreases, under the action of the spring 15, the sliding rod 10 gradually moves into the receiving groove 701, and the baffle 16 moves accordingly. The clamping plate 9 keeps squeezing the medicine bag 8, so that the medicine in the medicine bag 8 is delivered to the patient's body through the second puncture needle 14 and the annular tube 13.
[0031] When the liquid medicine in the liquid medicine bag 8 has all flowed out, the clamping plate 9 keeps squeezing the liquid medicine bag 8 under the action of the spring 15, and the baffle 16 is separated from the corresponding fixed block 7. After losing the support of the baffle 16, the fixed block 7 moves downward under its own gravity and falls on the fixed plate 2. When the fixed block 7 falls on the fixed plate 2, the second puncture needle 14 passes through the second plug hole 17 and pierces into the liquid medicine bag 8, automatically completing the liquid replacement. At the same time, the corresponding multiple fixed blocks 7 all move downward for a certain distance.
[0032] Similarly, in the counterclockwise direction, multiple fixed blocks 7 fall onto the fixed plate 2 in sequence so that the corresponding drug solution bag 8 is connected to the annular tube 13 through the second puncture needle 14. Multiple fixed blocks 7 automatically complete the liquid replacement work, without manual liquid replacement, saving labor and convenient use. In addition, the infusion set is small in size, has no power structure, and has a low manufacturing cost.
[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
