Description

Technical Field

[0001] The utility model relates to the technical field of venous infusion ports, in particular to a new type of anti-rotation implantable venous infusion port. Background Technique

[0002] The infusion port consists of two parts: an injection port and a catheter. The injection port is the size of a coin. The end of the catheter is divided into two types: three-way valve type and end-opening type. The common implantation sites of the infusion port are the internal jugular vein and the subclavian vein, and generally the subclavian vein is preferred for adults. After the tip of the catheter is located by X-ray, it must be at the junction of the right atrium and the superior vena cava.

[0003] After the existing venous infusion port is implanted, it often shifts and flips with the movement of the patient's limbs, resulting in symptoms such as redness, swelling, heat, and pain around the port body, causing the port body to shift, the catheter implanted in the subclavian vein to deviate, and at the same time, the injection port connected to the infusion needle under the skin to shift. Therefore, the catheter connecting the injection port inserted into the subclavian vein is blocked. Content of the Utility Model

[0004] The purpose of the utility model is to provide a new type of anti-rotation implantable venous infusion port to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A new type of anti-rotation implantable venous infusion port, including an injection port, an infusion needle connection seat, a catheter and an implantation assembly. The infusion needle connection seat is arranged at the sealing part of the injection port. The catheter is installed at the blood vessel access part of the injection port. The injection port is arranged at the implantation part of the implantation assembly. It also includes:

[0007] A positioning assembly, installed on the injection port;

[0008] An anti-infusion needle flipping assembly, arranged on the catheter;

[0009] Among them, a blood vessel access sleeve is installed at the top of the injection port. Through columns are fixed around the blood vessel access sleeve. An infusion needle through tube is arranged at the middle connection part of the infusion needle connection seat. A connecting tube is connected to the fixed part of the catheter. A spring cover is arranged at the connection part of the connecting tube.

[0010] For the new type of anti-rotation implantable venous infusion port as described above: The infusion needle through tube is installed on the through column through the infusion needle connection seat.

[0011] For the new type of anti-rotation implantable venous infusion port as described above: The connecting tube and the top catheter pass through the spring cover and are fixedly connected to the injection port.

[0012] The novel anti - flipping implantable venous infusion port as described above: The positioning component includes a fixed rubber sleeve movably installed on the infusion needle connector seat, and an internal insertion end is arranged inside the fixed rubber sleeve.

[0013] The novel anti - flipping implantable venous infusion port as described above: The fixed rubber sleeve is movably installed on the blood vessel access sleeve through the internal insertion end, and the fixed rubber sleeve is sleeved outside the through - column.

[0014] The novel anti - flipping implantable venous infusion port as described above: The anti - infusion - needle - flipping component includes a latex sleeve fixedly connected to the outside of the infusion needle through - tube, and folding sleeves are arranged around the latex sleeve.

[0015] The novel anti - flipping implantable venous infusion port as described above: The latex sleeve and the folding sleeves can be folded and deformed, and the infusion needle through - tube is snapped into the inside of the blood vessel access sleeve by pressing the folding sleeves.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the infusion needle through - tube is the insertion end of the non - traumatic needle (butterfly needle), the internal insertion end and the blood vessel access sleeve can be installed inside the injection seat, forming a long - term blood vessel access as a catheter inserted into the subclavian vein, which can play a role similar to a port. The internal insertion end and the blood vessel access sleeve prevent the injection seat from turning and shifting. The catheter and the connecting tube can move left and right elastically by relying on the spring cover, preventing the injection seat from turning and shifting when the catheter and the connecting tube are offset, preventing the venous infusion port from shifting and flipping, preventing redness, swelling, heat, pain around the port body and port body displacement, and preventing the catheter inserted into the subclavian vein from being offset.

[0017] The infusion needle through - tube is pressed into the inside of the infusion needle connector seat and the injection seat, facilitating the pressing and positioning of the infusion needle through - tube. The infusion needle through - tube prevents the injection seat connected to the infusion needle buried under the skin from shifting, can position the infusion needle through - tube and the injection seat, and prevent turning and shifting. Therefore, the catheter and the connecting tube can be normally connected to the blood vessels, preventing blood vessel blockage and other problems in the catheter and the connecting tube connecting the injection seat and the catheter inserted into the subclavian vein.

[0027] A positioning assembly is installed on the injection seat 1; an anti - infusion needle flipping assembly is provided on the catheter 8.

[0028] The infusion needle connection seat 4 is buckled on the injection seat 1, so that the catheter 8 is fixedly installed at the vascular access part of the injection seat 1. The injection seat 1 and the infusion needle connection seat 4 can be buried under the skin. The injection seat 1 is connected to the catheter 8 inserted into the subclavian vein to form a long - term vascular access, playing a role similar to a port.

[0029] Wherein, a vascular access sleeve 3 is installed at the top of the injection seat 1, through columns 2 are fixed around the vascular access sleeve 3, an infusion needle through tube 5 is provided at the middle connection part on the infusion needle connection seat 4, a connecting tube 7 is connected to the fixed part on the catheter 8, and a spring cover 6 is provided at the connection part on the connecting tube 7.

[0030] In this embodiment, the vascular access sleeve 3 is movably installed at the top of the injection seat 1, so that the infusion needle connection seat 4 and the infusion needle through-tube 5 are integrally snap-fitted onto the injection seat 1 and the vascular access sleeve 3. The infusion needle through-tube 5 on the infusion needle connection seat 4 serves as the insertion end of the non-invasive needle butterfly needle, preventing the venous infusion port from tipping and shifting. Then, the catheter 8 and the connecting tube 7 are passed through the inside of the spring cover 6. The spring cover 6 can protect the connection end of the catheter 8 and the connecting tube 7. The catheter 8 and the connecting tube 7 can move left and right elastically relying on the spring cover 6, preventing the injection seat 1 from tipping and shifting when the catheter 8 and the connecting tube 7 shift.

[0031] Preferably, the infusion needle through-tube 5 is installed through the infusion needle connection seat 4 on the through-column 2. The through-column 2 can be inserted into the infusion needle connection seat 4 and the infusion needle through-tube 5, so that the infusion needle connection seat 4 and the infusion needle through-tube 5 are firmly snap-fitted onto the injection seat 1.

[0032] Preferably, the connecting tube 7 and the top catheter 8 pass through the spring cover 6 and are fixedly connected to the injection seat 1. The catheter 8 and the connecting tube 7 can move left and right elastically relying on the spring cover 6, so that the catheter 8 and the connecting tube 7 are fixedly connected to one side of the injection seat 1, preventing the injection seat 1 from tipping and shifting when the catheter 8 and the connecting tube 7 shift.

[0033] Please refer to Figure 1 and Figure 2 , in this embodiment, the positioning assembly includes a fixed rubber sleeve 9 movably installed on the infusion needle connection seat 4, and an internal insertion end 10 is arranged inside the fixed rubber sleeve 9.

[0034] The fixed rubber sleeve 9 on the infusion needle connection seat 4 is sleeved on the through-column 2. The injection seat 1 is snap-fitted onto the infusion needle connection seat 4 through the through-column 2. The internal insertion end 10 inside the fixed rubber sleeve 9 is engaged into the injection seat 1 and the vascular access sleeve 3, and the infusion needle through-tube 5 on the infusion needle connection seat 4 serves as the insertion end of the non-invasive needle butterfly needle.

[0035] Preferably, the fixed rubber sleeve 9 is movably installed on the vascular access sleeve 3 through the internal insertion end 10. The fixed rubber sleeve 9 is sleeved outside the through-column 2. The infusion needle through-tube 5 on the infusion needle connection seat 4 is snap-fitted onto the through-column 2 through the fixed rubber sleeve 9, so that the internal insertion end 10 is engaged into the vascular access sleeve 3. When the infusion needle through-tube 5 serves as the insertion end of the non-invasive needle butterfly needle, the internal insertion end 10 and the vascular access sleeve 3 can be installed inside the injection seat 1, forming a long-term vascular access for the catheter 8 inserted into the subclavian vein, which can play a role similar to a port. The internal insertion end 10 and the vascular access sleeve 3 prevent the injection seat 1 from tipping and shifting.

[0036] Please refer to Figure 1 and Figure 3, in this embodiment, the anti-infusion needle flipping assembly includes a latex sleeve 11 fixedly connected to the outside of the infusion needle through-tube 5, and a folding sleeve 12 is arranged around the latex sleeve 11.

[0037] The infusion needle through-tube 5 is fixedly connected to the infusion needle connector 4 through the latex sleeve 11 and the folding sleeve 12, and is used as the insertion end of the non-invasive needle winged needle.

[0038] Preferably, the latex sleeve 11 and the folding sleeve 12 can be folded and deformed. The infusion needle through-tube 5 is snapped into the inside of the vascular access sleeve 3 by pressing the folding sleeve 12. When the infusion needle through-tube 5 on the infusion needle connector 4 is used as the insertion end of the non-invasive needle (winged needle), by pressing the infusion needle through-tube 5 and simultaneously squeezing the latex sleeve 11 and the folding sleeve 12 to deform, the infusion needle through-tube 5 can be pressed into the infusion needle connector 4 and the injection seat 1, which is convenient for positioning the pressing of the infusion needle through-tube 5.

[0039] As can be seen from the above, the infusion needle through-tube 5 on the infusion needle connector 4 is buckled on the through-column 2 through the fixed rubber sleeve 9, so that the built-in insertion end 10 is engaged with the vascular access sleeve 3. The infusion needle through-tube 5, as the insertion end of the non-invasive needle (winged needle), and the vascular access sleeve 3 is movably installed at the top of the injection seat 1, so that the infusion needle connector 4 and the infusion needle through-tube 5 are integrally buckled on the injection seat 1 and the vascular access sleeve 3.

[0040] The built-in insertion end 10 and the vascular access sleeve 3 can be installed inside the injection seat 1, and form a long-term vascular access as the catheter 8 inserted into the subclavian vein, which can play a role similar to a port. The built-in insertion end 10 and the vascular access sleeve 3 prevent the injection seat 1 from turning and shifting.
