Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an auxiliary compression positioning device. Background Technology

[0002] A fully implantable intravenous drug delivery device, also known as a fully implantable port-a-catheter or simply port-a-catheter, is a closed intravenous infusion system that is fully implanted in the body and can be used long-term. It consists of an injection port implanted under the skin and a venous catheter ligation suture. It can withstand 1,000 to 2,000 non-traumatic needle punctures. Compared with peripherally inserted central catheters (PICCs), it is safer and more convenient, and can be left in place for 10 to 20 years. However, in the actual application of port-a-catheter, medical staff and patients also face some problems and challenges. Because the puncture diameter of the port-a-catheter is small and requires precise positioning, the needle is very likely to puncture the fingers of medical staff during the puncture process, and patients may experience pain due to repeated punctures. Based on the above problems and challenges, auxiliary squeezing and positioning devices for port-a-catheter have emerged.

[0003] However, existing technologies have the following problems in practical use:

[0004] Current technology mainly relies on medical staff to manually squeeze and position the infusion port. Since the positioning process depends entirely on the personal experience and feel of the medical staff, the positioning results are highly subjective, which may affect the accuracy and consistency of the positioning results.

[0017] (3) Beneficial effects

[0018] This utility model provides an auxiliary extrusion positioning tool, which has the following beneficial effects:

[0019] This auxiliary compression positioning device, through the coordinated arrangement of a base, pressure cover, and clamp, enables the device to position and clamp the infusion port during use. The base and clamp, when locked, create downward pressure on the pressure cover, squeezing the skin and causing the subcutaneous infusion port to naturally emerge due to the compression of surrounding tissue, thus completing the positioning and clamping of the infusion port. Furthermore, the locking mechanism of the clamp and base allows for quick locking and unlocking. The snap-on design allows medical personnel to quickly remove the entire device from the patient after completing the butterfly needle puncture and removing the clamp. Attached Figure Description

[0028] Example 1:

[0029] Please see Figure 2 , Figure 4 and Figure 5 This utility model provides a technical solution: an auxiliary squeezing and positioning tool, which is provided with a base 1, a pressure cover 4 and a clamping plate 5 in order to position and clamp the infusion port during use;

[0030] The system includes a base 1, a pressure cover 4 for pressing inserted into the middle of the base 1, a clamping plate 5 for locking fixedly installed on the top of the pressure cover 4, a hinge 6 for connection fixedly installed on one side of the base 1, and ring straps 7 fixedly connected to both ends of the base 1. A through hole 13 for pressing is opened in the middle of the pressure cover 4, and a protective pad 14 is fixedly installed at the bottom of the pressure cover 4. A chuck 15 for limiting is inserted into the top of the clamping plate 5, and a limiting knob 16 is inserted into the middle of the chuck 15. A limiting groove 17 for limiting is opened in the middle of the base 1, and a locking block 18 adapted to the groove 17 is provided in the pressure cover 4. A limiting groove 19 is opened on the top of the base 1, and a locking block 20 adapted to the limiting groove 19 is provided in the knob 16. Therefore, during use, the hinge 6 can connect the base 1 into a whole, the ring 7 is used to connect the adhesive tape 2, and the through hole 13 can not only squeeze the skin, position and clamp the infusion port, but also provide operating space for inserting the butterfly needle. The pad 14 is made of soft material to reduce the pressure on the skin and improve patient comfort. The chuck 15 is used to tightly connect the knob 16 and the clamp 5. The knob 16 can be locked onto the top of the base 1 by the cooperation of the limiting groove 19 and the locking block 20, thereby locking the clamp 5 and the base 1. Furthermore, the pressure cover 4 can be squeezed downward by the cooperation of the slot 17 and the locking block 18.

[0031] Example 2:

[0032] Please see Figure 1 In order to allow the device to be removed quickly and safely after use, a latch 3 is provided;

[0033] A latch 3 for locking is fixedly installed on one side of the base 1. A handle 10 is rotatably connected to one side of the latch 3. A retaining ring 11 is fixedly installed on one side of the handle 10. A hook 12 is fixedly installed on the other side of the latch 3. Therefore, during use, the latch 3 can be easily locked and unlocked by the handle 10. The locking ring 11 and the hook 12 can be used to lock the two bases 1 tightly and connect them into a whole.

[0034] Example 3:

[0035] Please see Figure 3 In order to allow the device to be fixed on the patient's skin and to provide support for the squeeze port, a patch 2 is provided;

[0036] Both sides of the base 1 are fixedly installed with adhesive tapes 2 for fixation. One side of the adhesive tape 2 is fixedly installed with a D-ring buckle 8 for connection, and the other side of the adhesive tape 2 is fixedly connected with adhesive tape 9. Therefore, during use, the base 1 and the adhesive tape 2 can be connected by the D-ring buckle 8, and the adhesive tape 9 is used to directly stick to the patient's skin to ensure that the base 1 is stable and does not move.

[0037] In this invention, the working steps of the device are as follows:

[0038] First, fix the base 1 to the patient using the adhesive tape 2 and tape 9, aligning the pressure cover 4 with the location of the infusion port. Then, align the locking block 18 on the pressure cover 4 with the locking groove 17 on the base 1, and install the pressure cover 4. Next, rotate the knob 16 to lock the clamp 5 and the base 1, causing the pressure cover 4 to press down on the skin to complete the positioning and clamping of the infusion port. Finally, after the butterfly needle puncture is completed, rotate the knob 16 to release the locking of the clamp 5 and the base 1, and turn the handle 10 to release the locking ring 11 and the hook 12, and remove the device.
