Description

Technical Field

[0001] The utility model relates to the technical field of catheter flushers, in particular to a double-lumen pre-filled catheter flusher. Background Art

[0002] A catheter flusher is a medical tool specifically used to flush various types of catheters. It is usually made of durable materials, has a reasonable structural design, and is easy to operate. The catheter flusher can effectively clean the inside of the catheter and prevent catheter blockage and infection by precisely controlling the flow and pressure of the flushing fluid. In the medical field, such as the maintenance of intravenous catheters and urinary catheters, catheter flushers play an important role. They can improve the safety and effectiveness of catheter use, reduce the risk of complications caused by catheter problems, and provide strong protection for patients' treatment and recovery.

[0003] Existing technologies include the utility model with publication number CN217797893U, which discloses a prefilled double-lumen catheter flusher. The patent adopts a double-lumen catheter body, a first chamber connection port, a second chamber connection port, a first chamber flusher, a second chamber flusher, and a flusher connection push plate. The two chambers of the double-lumen catheter are flushed by the chamber flusher, which can reduce the chance of contamination and the risk of infection. It is highly safe and avoids needlestick injuries to medical staff. The two chamber flushers are connected together, and the two chambers of the catheter are flushed simultaneously by the two connected chamber flushers, which is convenient for medical staff to operate, reduces operation time, and improves work efficiency. The device has a simple structure, low cost, and is easy to operate. It is suitable for large-scale popularization, making the work of medical staff more convenient. It solves the problems that the existing 5Fr catheter is divided into two lumens, the lumen is small, and it is inconvenient to disinfect. The catheter is open-tip and has no valve, which is prone to reflux. The lumens on both sides are easily squeezed against each other, causing inconvenience in subsequent use and increasing the workload of medical staff.

[0004] In the process of flushing the catheter with the help of a double-chamber flusher, there is a problem that when the existing double-chamber flusher, such as the above-mentioned double-chamber flusher, is used, the flushing flow rate formed by the chambers on both sides is the same. However, due to the different specifications of the flushed catheters during actual flushing, when a larger flow rate is used to flush the small catheter, the impact force of the large flow rate is stronger, causing the large flow rate to damage the catheter when flushing the small catheter, thereby affecting the treatment effect and seriously increasing the risk of infection for the patient.

The inner wall of the mounting frame 611 is slidably connected to the guide plate 1 614. The inner wall of the mounting frame 611 is slidably connected to the guide plate 2 615. The upper surfaces of the guide plate 1 614 and the guide plate 2 615 are both provided with grooves. The guide plates 1 614 and the guide plates 2 615 are fixedly connected to the inner walls of the grooves with sealing gaskets 616.

[0028] The adjustment assembly 6 also includes a restraining unit 62, which includes a compression spring 622. Installation cavities 621 are provided on both sides of the top plate 617. The top plate 617 is located on the inner wall of the installation cavity 621 and is fixedly connected to the compression spring 622. The top plate 617 is located on the inner wall of the installation cavity 621 and is slidably connected to a positioning pin 623. The positioning pin 623 is fixedly connected to the free end of the compression spring 622. The side of the positioning pin 623 away from the compression spring 622 is fixedly connected to a connecting column 624. The side surface of the connecting column 624 is fixedly connected to an anti-slip plate 625. A slot 626 is provided on the inner wall of the storage rack 612, and the positioning pin 623 is plugged into the inner wall of the slot 626.

[0029] Specifically, the mounting bracket 611 is connected to the connector 5 , and a circular hole is provided on the surface of the guide plate 1 614 , which is connected to the connector 5 .

[0030] In this embodiment, the cooperation between the guide plate 614 and the circular hole can keep the flow rate of the connector 5 within a normal range, so that it is suitable for thicker catheters.

[0031] Specifically, a through hole is opened on the surface of the second guide plate 615, and the diameter of the through hole is smaller than the circular hole. Through the cooperation between the second guide plate 615 and the through hole, the flow of the connector 5 can be reduced, thereby making the flow suitable for a thinner catheter.

[0032] In this embodiment, the sealing gasket 616 contacts the inner wall of the mounting frame 611 , and the sealing ring 618 contacts the inner wall of the storage frame 612 .

[0033] In this embodiment, the contact portions between the guide plate 1 614 , the guide plate 2 615 and the mounting bracket 611 can be sealed by the sealing gasket 616 , thereby improving the sealing effect of the connection portions.

[0034] Specifically, the positioning pin 623 passes through the side surface of the storage rack 612. There are two positioning pins 623, and the two positioning pins 623 are symmetrically arranged with respect to the storage rack 612.

[0035] Specifically, the connecting column 624 is slidably connected to the inner wall of the storage rack 612 .

[0036] In this embodiment, the anti-slide plate 625 and the positioning pin 623 can be connected via the connecting column 624 , so that the staff can adjust the state of the positioning pin 623 when operating the anti-slide plate 625 .

[0037] Working principle: When flushing the catheter, push the push rod 2, and the push rod 2 squeezes the flushing saline in the shunt tube 1, and the flushing saline is injected into the injection tube 4. The injection tube 4 cooperates with the connector 5 to inject the flushing saline into the catheter, thereby flushing the catheter; when the catheter that needs to be flushed is thinner, press the anti-slide plates 625 on both sides, and the anti-slide plates 625 cooperate with the connecting column 624 to push the positioning pin 623, and the positioning pin 623 squeezes the compression spring 622. The compression spring 622 is squeezed and deformed, and the positioning pin 623 is forced to disengage from the slot 626 and loses the restriction on the top plate 617. When the anti-slide plate 625 reaches the surface of the storage rack 612, it pushes the anti-slide plate 625, and the anti-slide plate 625 cooperates with the connecting column 624 to push the top plate 617. The top plate 617 pushes the guide plate 2 615, and the guide plate 2 615 pushes the guide plate 1 614. The guide plate 1 614 and the guide plate 2 615 are equally stressed. When the guide plate 2 moves forward, the guide plate 2 615 replaces the guide plate 1 614 in the process of moving to connect the mounting bracket 611 and the connector 5. When the guide plate 2 615 moves to the maximum spacing, the anti-slip plate 625 is released, the connecting column 624 loses the pressure applied to the positioning pin 623, the positioning pin 623 loses the pressure applied to the compression spring 622, the compression spring 622 loses the pressure and rebounds, and pushes the positioning pin to be inserted into another slot 626, thereby locking the top plate 617. When the top plate 617 is locked, it limits the position of the convection plate 2, and then completes the regulation of the flow of the connector 5. By setting the adjustment component 6, the user can adjust the flow of the flusher according to the thickness of the catheter, thereby reducing the problem of the flusher easily damaging the catheter when flushing a small catheter with a large flow rate, and further improving the safety of the flusher during the flushing process.
