Description

Technical Field

[0001] The present application relates to the field of medical device technology, and in particular to an infusion port auxiliary kit. Background Art

[0002] In modern medicine, most cancer patients need chemotherapy, and chemotherapy drugs are introduced into the patient's body through a central venous catheter such as an infusion port or PICC. An infusion port is an intravenous infusion device implanted subcutaneously and left in the body for a long time. It is clinically suitable for patients who need long-term infusion and chemotherapy.

[0003] In the prior art, since the port body is small and buried under the skin, nursing staff can only perform blind puncture for patients based on experience. First of all, blind puncture is prone to position deviation, resulting in drug extravasation, and repeated punctures are likely to increase the risk of infection and damage the silicone membrane of the infusion port. Secondly, the butterfly wing needle of the infusion port is currently mostly fixed with a biological film. With the daily activities of the patient, the biological film is prone to displacement and curling, making it impossible for the biological film to effectively fix the butterfly wing needle; and when the butterfly wing needle is not stably fixed and the puncture depth changes, the needle will pierce the base of the infusion port if it is too deep, which will sharply reduce the life of the infusion port. If the needle is too shallow, the flow path cannot be formed, which will increase the risk of using the infusion port needle. Summary of the invention

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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.

[0022] The present application embodiment discloses an infusion port auxiliary kit. Figure 1 , Figure 2 and Figure 3 An infusion port auxiliary kit is used in conjunction with an infusion port and a butterfly wing needle 1, which includes a marking device and a fixing device. When in use, the marking device can be used to first identify and locate the position of the patient's subcutaneous infusion port and a stamp mark can be made at the position corresponding to the center of the infusion port on the patient's surface skin, and then the butterfly wing needle 1 can be aligned with the mark on the patient's skin and inserted into the infusion port, and the butterfly wing needle 1 can be fixed on the patient's surface skin at an appropriate puncture depth through the fixing device.

[0023] Reference Figure 1 The marking device includes a base 2, a seal body 3 movably inserted through the center of the base 2, and an infrared recognition component for identifying whether the base 2 and the infusion port are concentrically distributed. The base 2 is a circular cover structure, and a through hole is provided at the center of the base 2 for the seal body 3 to be movably inserted. A guide ring body 9 is protruding at the center of the top of the base 2, and the guide ring body 9 is coaxially arranged with the base 2. A sliding sleeve is provided on the guide ring body 9, and the slide tube 4 is installed at the center of the base 2 for lifting and sliding; the top of the seal body 3 is fixed to the middle of the slide tube 4, and the bottom of the seal body 3 is inserted into the guide ring body 9; a compression spring 5 is connected between the slide tube 4 and the base 2, and the compression spring 5 is sleeved on the seal body 3, and one end of the compression spring 5 extends into the guide ring body 9 and is fixedly connected to the guide ring body 9, and the other end is fixedly connected to the seal body 3; by pressing the slide tube 4, the compression spring 5 is compressed, and at this time the slide tube 4 is lifted and slid on the base 2, and the slide tube 4 can drive the bottom of the seal body 3 to move through the through hole at the center of the guide ring body 9 and the base 2, so as to realize the seal marking on the patient's skin.

[0024] To check whether the stamp body 3 is aligned with the patient's subcutaneous infusion port before stamping, refer to Figure 1 The infrared recognition component includes an infrared transmitter 6 installed on the top of the slide 4 and used to identify the position of the infusion port, a display screen 7 for displaying the position of the infusion port, and a concentric detection and analysis module 8 for monitoring and analyzing the degree of deviation between the center of the infusion port and the center of the display screen 7. The infrared transmitter 6 can perform infrared recognition of the position of the infusion port under the patient's skin and feed back the recognized information to the display screen 7. The concentric detection and analysis module 8 guides the nursing staff to adjust the position of the marking device by analyzing the degree of deviation between the center of the infusion port and the center of the display screen 7, until the center of the infusion port coincides with the center of the display screen 7; at this time, by pressing the slide 4, the seal body 3 can accurately mark the position of the infusion port on the patient's skin, thereby providing guidance for the puncture of the butterfly needle 1.

[0025] After the position of the infusion port is marked, in order to prevent the butterfly needle 1 from puncturing the infusion port, a fixing device is needed to adjust the puncture depth and fix the position of the butterfly needle 1. Figure 2 and Figure 3 The fixing device includes a base 10, an adhesive layer arranged on the bottom surface of the base 10, and a positioning component arranged on the top surface of the base 10 and used to adjust the puncture depth of the butterfly wing needle 1 and fix the butterfly wing needle 1. A perforation 11 for the needle head of the butterfly wing needle 1 to puncture is provided at the center of the base 10, and a release paper is adhered to the adhesive layer. When the butterfly wing needle 1 needs to be fixed on the patient's skin at a suitable depth, the release paper can be torn off first, and then the perforation 11 is aligned with the seal mark on the patient's skin, and the base 10 is stably aligned and attached to the patient's skin, and then the butterfly wing needle 1 is aligned through the perforation 11 and inserted into the infusion port under the patient's skin. Finally, the puncture depth of the butterfly wing needle 1 is adjusted through the positioning component and the butterfly wing needle 1 is stably fixed.

[0026] For the positioning component settings, refer to Figure 2 and Figure 3 The positioning assembly includes an outer sleeve 12 fixed at the center of the base 10, an inner sleeve 13 movably plugged into the outer sleeve 12, and a pressure cap 14 detachably covered on the end of the inner sleeve 13. The inner diameter of the inner sleeve 13 is not less than the distance between the two wing handles of the butterfly needle 1, so that when puncturing, the inner sleeve 13 can be first inserted into the outer sleeve 12, and then the butterfly needle 1 is placed in the inner sleeve 13 and covered with the pressure cap 14, and then the inner sleeve 13 is pushed downward, and the inner sleeve 13 pushes the butterfly needle 1 downward through the pressure cap 14 and inserts it into the subcutaneous infusion port of the patient. In order to stabilize the puncture depth of the butterfly needle 1, a locking structure for locking the two is provided between the outer sleeve 12 and the inner sleeve 13. Through the locking structure, the depth of the inner sleeve 13 inserted into the outer sleeve 12 is adjusted, so that the pressure cap 14 presses the butterfly needle 1 to penetrate the perforation 11 at a suitable depth and insert it into the infusion port.

[0027] Reference Figure 2 A retaining ring 18 is arranged on the inner wall of the top of the outer sleeve 12, and the locking structure is an internal thread 15 arranged on the inner wall of the retaining ring 18 and an external thread 16 arranged outside the inner sleeve 13. The inner sleeve 13 is spirally connected in the outer sleeve 12, and the retaining ring 18 is threaded through the bottom of the inner sleeve 13 and inserted into the outer sleeve 12. By driving the inner sleeve 13 to rotate in the outer sleeve 12, the depth of the inner sleeve 13 inserted into the outer sleeve 12 is adjusted, so that the butterfly needle 1 can achieve stepless adjustment of the puncture depth under the push of the gland 14.

[0028] In order to prevent the inner sleeve 13 from being inserted too deep during the rotation of the inner sleeve 13, thereby causing the butterfly needle 1 to puncture the infusion port, Figure 2A spring 17 is provided in the outer sleeve 12 for limiting the maximum insertion depth of the inner sleeve 13. The spring 17 is located directly above the through hole 11 of the base 10, and one end of the spring 17 is fixedly connected to the inner wall of the outer sleeve 12, and the other end is movably abutted against the bottom of the inner sleeve 13. When the inner sleeve 13 is driven to rotate in the outer sleeve 12 so that the inner sleeve 13 moves toward the base 10, the spring 17 is compressed until the spring 17 is compressed to the minimum length, and the inner sleeve 13 can no longer be inserted into the outer sleeve 12. At this time, the butterfly needle 1 is also inserted into the infusion port to the maximum depth without damage.

[0029] Reference Figure 2 The bottom of the inner sleeve 13 is provided with an axis and an extension tube 19 is integrally formed. The outer wall of the extension tube 19 is smooth, and the outer diameter of the extension tube 19 is smaller than the inner diameter of the retaining ring 18. The inner diameter of the extension tube 19 is equal to the inner diameter of the inner sleeve 13. When the inner sleeve 13 is rotated so that the outer thread 16 on the inner sleeve 13 is located above the retaining ring 18, the extension tube 19 enters the retaining ring 18. At this time, the spring 17 can push the inner sleeve 13 upward, thereby releasing the elastic potential energy in the spring 17 and extending the service life of the spring 17.

[0030] In order to prevent the spring 17 from ejecting the inner sleeve 13 from the outer sleeve 12, Figure 2 A limiting ring 20 is sleeved on the bottom of the extension tube 19. The outer diameter of the limiting ring 20 is larger than the inner diameter of the retaining ring 18. When the external thread 16 on the inner sleeve 13 is located above the retaining ring 18, the limiting ring 20 is still located below the retaining ring 18, ensuring that the inner sleeve 13 can be mounted and connected to the outer sleeve 12.

[0031] Since the butterfly needle 1 is connected to an infusion tube, in order to conveniently fix the infusion tube, refer to Figure 2 and Figure 3, a notch 21 for installing the infusion tube on the butterfly wing needle 1 is provided on the top of the inner sleeve 13, and a notch 22 corresponding to the notch 21 is provided on the pressure cover 14. When the pressure cover 14 is covered on the top of the inner sleeve 13, the infusion tube on the butterfly wing needle 1 can pass through the hole formed by the notch 21 and the notch 22. At the same time, a fixing component for fixing the infusion tube on the butterfly wing needle 1 is provided on the base 10. In the embodiment of the present application, four groups of fixing components are provided, and the four groups of fixing components are evenly distributed on the surrounding side of the base 10. One or more groups of fixing components can be selected as needed to fix the infusion tube on the butterfly wing needle 1. The fixing component includes a fixing belt 25 installed on the base 10, a double-sided adhesive 26 bonded to the middle of the fixing belt 25, a Velcro 27 sewn on the fixing belt 25, and a non-woven fabric 28 fixed on the upper surface of the base 10, and the Velcro 27 can be freely attached to the non-woven fabric 28. After the infusion tube on the butterfly wing needle 1 passes through the hole formed by the notch 21 and the groove 22, the infusion tube is connected to the fixing belt 25 by the double-sided tape 26, and then the fixing belt 25 with the infusion tube is fixed to the base 10 by the Velcro 27 and the non-woven fabric 28, thereby preventing the infusion tube from swinging randomly and affecting the puncture position of the butterfly wing needle 1, thereby ensuring the safety of the patient's infusion.

[0032] Considering that the butterfly needle 1 cannot be inserted into the infusion port for a long time and needs to be removed regularly, Figure 2 and Figure 3 The top of the inner sleeve 13 is also provided with an embedding groove 23, in which a timer 24 is arranged, and the timer 24 is stably fixed on the inner sleeve 13 through the gland 14. The timer 24 can be set with an alarm number of days, and can automatically alarm when the usage period expires, so as to prevent the patient from forgetting to remove the butterfly needle 1 when leaving the hospital after chemotherapy.

[0033] The implementation principle of the infusion port auxiliary kit of the embodiment of the present application is as follows: first, preliminarily find the position of the subcutaneous infusion port of the patient, and press the base 2 on the patient's skin, then start the infrared recognition component to determine whether the current base 2 and the infusion port are concentrically distributed, and adjust the position of the base 2 according to the adaptability of the infrared recognition component until the center of the base 2 coincides with the center of the infusion port. Then, press the slide 4 so that the seal body 3 can accurately mark the position of the infusion port on the patient's skin, thereby providing guidance for the puncture of the butterfly wing needle 1.

[0034] After the position marking of the infusion port is completed, the release paper is torn off from the base 10, and then the base 10 is stably aligned and attached to the patient's skin through the perforation 11, and then the butterfly needle 1 is placed into the inner sleeve 13 and inserted into the infusion port under the patient's skin through the perforation 11. Then, the pressure cap 14 is covered, and the inner sleeve 13 is driven to rotate in the outer sleeve 12. Under the joint action of the internal thread 15 and the external thread 16, the inner sleeve 13 moves toward the base 10, so that the pressure cap 14 pushes the butterfly needle 1 into the infusion port until the butterfly needle 1 is inserted into the infusion port at a suitable depth.

[0035] After the puncture of the butterfly wing needle 1 is completed, the infusion tube on the butterfly wing needle 1 can be fixed by the fixing component, so as to prevent the infusion tube from swinging randomly and affecting the puncture position of the butterfly wing needle 1, thereby ensuring the safety of the patient's infusion.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
