[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0032] See also Figure 1-7 An intelligent infusion port provided by an embodiment of the present invention comprises an injection seat 1 and a catheter 2, wherein an inner cavity 3 is arranged in the injection seat 1, and further comprises: a butt joint tube 4, which is arranged on the side wall of the injection seat 1 and communicates with the inner cavity 3, and whose tube wall has an elastic arrangement; a sleeve 5, which is arranged at one end of the catheter 2 connected to the injection seat 1, and is sleeved on the butt joint tube 4; a barb groove 6 is arranged on the inner wall of the sleeve 5, and a comb row 7 matching the barb groove 6 is arranged on the outer wall of the butt joint tube 4; a tensioning component, which is arranged in the tube wall entity of the butt joint tube 4, and is used to prop up part of the outer wall of the butt joint tube 4 to lock the catheter 2 when the sleeve 5 slides on the butt joint tube 4 away from the injection seat 1.

[0033] Specifically, the injection seat 1 is approximately truncated; the end of the catheter 2 away from the injection seat 1 is closed, and a hole is opened on the side of the end for conduction; when the catheter 2 is implanted in the human body, a guide wire is passed through the inside. After implantation in the human body, the guide wire is pulled out of the catheter 2, and the catheter 2 is cut to a suitable length, and the cut is flat and not tilted; the wall of the catheter 2 has an elastic setting; the inner cavity 3 is used to receive the drug injected from the outside, and then directly introduce it into the human vein through the catheter 2. The butt joint tube 4 is arranged on the side wall of the injection seat 1 and close to the lower end, and the extension direction is arranged along the radial direction of the injection seat 1; the outer diameter of the end of the butt joint tube 4 matches the inner diameter of the catheter 2, and the inner diameter of the sleeve 5 is consistent with the inner diameter of the catheter 2. When the sleeve 5 is completely sleeved on the butt joint tube 4, a part of the catheter 2 is also sleeved on the outside of the butt joint tube 4; the barb groove 6 is continuously arranged along the axial direction on the inner wall of the sleeve 5; the comb row 7 includes a plurality of comb teeth, and the ends of the comb teeth are inclined toward the outside of the butt joint tube 4 and toward the injection seat 1, and the comb teeth have bending elasticity; when the sleeve 5 is sleeved on the butt joint tube 4, the movement of the sleeve 5 in this direction can be squeezed through along the inclined direction of the comb teeth, and the comb row 7 is instantly stuck in the barb groove 6 through the elastic restoring force, thereby hindering the sleeve 5 from moving in the opposite direction; the part of the butt joint tube 4 supported by the tensioning component corresponds to the overlapping part of the butt joint tube 4 and the catheter 2. In actual use of the present technical solution, after the catheter 2 and the injection seat 1 are successively implanted into the human body, one end of the catheter 2 provided with the sleeve 5 is sleeved with the docking tube 4. When the sleeve 5 is gradually sleeved onto the docking tube 4, the inner barb groove 6 thereof is squeezed through along the inclined direction of the comb teeth of the comb row 7, and the comb teeth automatically elastically recover to be stuck in the barb groove 6, thereby preventing the sleeve 5 from sliding off the docking tube 4 in the opposite direction, that is, preventing the catheter 2 from slipping and detaching. Furthermore, even when the sleeve 5 slides away from the injection seat 1 on the docking tube 4, the tensioning assembly can be triggered to prop up the outer wall of the overlapping part of the docking tube 4 and the catheter 2, thereby tightening the docking tube 4 on the inner side of the catheter 2 to lock the catheter 2, thereby improving the function of preventing the catheter 2 from detaching from the injection seat 1.

[0034] The technology used by the catheter 2 is PICC peripheral vein puncture central venous catheterization. Its basic method of use is to use this type of catheter 2 to puncture the vein of the peripheral arm, and the insertion end directly reaches the large vein close to the heart, while the other end is left outside the human body and is provided with a drug injection structure. Drugs are injected through the drug injection structure to avoid direct contact between chemotherapy drugs and arm veins. In addition, the blood flow rate of large veins is very fast, which can quickly dilute chemotherapy drugs and prevent drugs from irritating blood vessels. Therefore, it can effectively protect upper limb veins, reduce the occurrence of phlebitis, relieve patients' pain, and improve patients' quality of life.

[0035] Compared with the prior art, when a smart infusion port proposed in an embodiment of the present invention is sleeved on the docking tube 4 through the sleeve 5, the comb row 7 on the docking tube 4 can be stuck in the barb groove 6 on the inner wall of the sleeve 5, thereby preventing the catheter 2 from slipping and detaching, and an additional tensioning component is provided. Even if the sleeve 5 slips on the docking tube 4, the tensioning component can be triggered to prop up part of the outer wall of the docking tube 4, and then tightened on the inner side of the catheter 2 to lock the catheter 2, thereby improving the function of preventing the catheter 2 from detaching from the injection seat 1 and improving the practicality of the device.

[0036] As a preferred technical solution of this embodiment, the tensioning assembly includes a sliding member 8 movably arranged in the wall entity of the butt tube 4 along its length direction, the comb row 7 is fixedly connected to one end of the sliding member 8, and the other end of the sliding member 8 is continuously hinged with a first support portion 9, a second support portion 10 and an abutment portion 11 in sections, and the abutment portion 11 is relatively fixedly arranged with the butt tube 4. Specifically, one end of the sliding member 8 away from the injection seat 1 is hinged to one end of the first support portion 9, the other end of the first support portion 9 is hinged to one end of the second support portion 10, and the other end of the second support portion 10 is hinged to one end of the abutment portion 11; the hinge between the sliding member 8 and the first support portion 9 and the second support portion 10 and the abutment portion 1 1 are both provided with a notch on one side corresponding to the outer side of the butt joint 4, and another notch is provided on one side corresponding to the inner side of the butt joint 4 at the first supporting portion 9 and the second supporting portion 10; the above arrangement makes the rotation direction of the first supporting portion 9 relative to the sliding member 8 limited to: the end of the first supporting portion 9 away from the sliding member 8 rotates toward the outer side of the butt joint 4; the rotation direction of the second supporting portion 10 relative to the abutting portion 11 is limited to: the end of the second supporting portion 10 away from the abutting portion 11 rotates toward the outer side of the butt joint 4; combined with the above rotation of the first supporting portion 9 and the second supporting portion 10, the first supporting portion 9 and the second supporting portion 10 are supported toward the outer side of the butt joint 4.

[0037] As a preferred technical solution of this embodiment, a sliding groove 12 matching the sliding member 8 is opened in the wall of the butt-joint tube 4, and the first supporting portion 9, the second supporting portion 10 and the abutting portion 11 are arranged in the sliding groove 12. Specifically, the sliding groove 12 is used to provide activity space for the sliding member 8, the first supporting portion 9 and the second supporting portion 10, and under the elastic setting of the butt-joint tube 4, the activity of the supporting action of the first supporting portion 9 and the second supporting portion 10 is also satisfied; the end of the abutting portion 11 away from the second supporting portion 10 is fixedly connected to the inner wall of the sliding groove 12.

[0038] As a further preferred technical solution of the present embodiment, the solid thickness of the tube wall of the sliding groove 12 relative to the inner side of the butt-joint tube 4 is greater than the solid thickness of the tube wall of the sliding groove 12 relative to the outer side of the butt-joint tube 4. Specifically, the wall thickness of the sliding groove 12 relative to the inner side of the butt-joint tube 4 is set thicker, so that when the first supporting part 9 and the second supporting part 10 are in the supporting action, the sliding groove 12 is less deformed toward the inner side of the butt-joint tube 4, thereby reducing the influence on the internal tube diameter of the butt-joint tube 4.

[0039] In another embodiment of the present invention, a diaphragm 13 is provided on the upper side of the inner cavity 3, a ring body 14 is rotatably provided in the inner cavity 3, a brush rod 15 arranged close to the inner wall of the inner cavity 3 is fixedly connected to the ring body 14, an elastic roll sheet 16 is provided in the inner cavity 3, the outer end of the elastic roll sheet 16 is fixedly connected to the inner wall of the ring body 14, and the inner end is radially movable relative to the ring body 14, and a driving component for driving the ring body 14 to rotate is provided in the injection seat 1. Specifically, the ring body 14 is coaxially provided with the inner cavity 3, and the rotation of the ring body 14 drives the brush rod 15 to rotate and scrape close to the inner wall of the inner cavity 3; the elastic roll sheet 16 is provided in a spiral shape, and the axial direction is parallel to or coincides with the axial direction of the ring body 14; the outer end of the elastic roll sheet 16 can rotate with the ring body 14, and the inner end of the elastic roll sheet 16 is only relative to the ring body 14. The ring body 14 moves radially without relative rotation, and when the ring body 14 drives the outer end of the elastic roll 16 to rotate, the elastic roll 16 is deformed to generate elastic potential energy, and the deformation of the elastic roll 16 causes the inner end of the elastic roll 16 to move closer to the axis of the elastic roll 16; the driving component drives the ring body 14 to rotate actively, so that the ring body 14 drives the brush rod 15 to rotate and scrape the inner wall of the inner cavity 3. At this time, in conjunction with the pulse flushing method used in the prior art, physiological saline is injected into the inner cavity 3 in a pulsed manner through the outside, so that the inner cavity 3 can be better cleaned, and each time the driving component stops, the elastic roll 16 can release the elastic potential energy to drive the ring body 14 to rotate, thereby resetting the brush rod 15 and can reversely clean the inner wall of the inner cavity 3 again.

[0040] As a preferred technical solution of this embodiment, a sliding sleeve 17 is provided between the diaphragm 13 and the ring body 14 along the radial direction of the ring body 14 and fixedly connected to the inner wall of the inner cavity 3. A telescopic member 18 is slidably connected to the sliding sleeve 17. One end of the telescopic member 18 extends out of the sliding sleeve 17 and is fixedly connected to the inner end of the elastic roll sheet 16. Specifically, the setting of the sliding sleeve 17 and the telescopic member 18 limits the inner end of the elastic roll sheet 16 to move only along the radial direction of the ring body 14, and cannot rotate relative to the ring body 14.

[0041] As a preferred technical solution of this embodiment, the driving assembly includes a driving unit 19 arranged in the injection seat 1, the output end of the driving unit 19 is coaxially connected with a gear 20, the outer wall of the ring body 14 is provided with a toothed ring 21 meshing with the gear 20, and the driving unit 19 is provided with a wireless power supply 22, and the wireless power supply 22 can be powered by an external wireless power supply unit 23. Specifically, an extension seat is provided on the side wall of the injection seat 1, and the driving unit 19 and the wireless power supply 22 are arranged in the extension seat; the driving unit 19 can be preferably a micro motor, which is electrically connected to the wireless power supply 22. When the wireless power supply 22 is triggered to supply power by the external wireless power supply unit 23, the driving unit 19 can be started, and the driving unit 19 drives the gear 20 to rotate in a certain direction, and the gear 20 is then transmitted through the toothed ring 21 to drive the ring body 14 to rotate, and the rotation direction of the ring body 14 is set along the spiral direction of the elastic coil 16; since the injection seat 1 is buried under the skin, the wireless power supply unit 23 can power the wireless power supply 22 through the skin. This is a prior art and will not be repeated.

[0042] As the preferred technical solution of this embodiment, it also includes a non-destructive puncture needle 24, whose needle head vertically penetrates the middle part of the diaphragm 13 and extends to the lower side of the ring body 14. Specifically, the non-destructive puncture needle 24 needs to be manually inserted when injecting drugs or flushing the infusion port. Specifically, it needs to pass through the diaphragm 13 and enter the inner cavity 3. During this process, the insertion depth of the non-destructive puncture needle 24 needs to be controlled more accurately, otherwise the following problems will occur: the needle head of the non-destructive puncture needle 24 contacts and squeezes the inner bottom surface of the inner cavity 3, causing the needle head to bend. Then, in this case, when the non-destructive puncture needle 24 is pulled out, there is a problem that the bent needle head will hook and scratch the injection seat 1, causing damage to the diaphragm 13 and generating debris in the inner cavity 3.

[0043] As a preferred technical solution of this embodiment, the wireless power supply unit 23 can intermittently supply power to the wireless power supply 22 to make the ring body 14 reciprocate or supply power to the wireless power supply 22 for a long time to make the ring body 14 rotate a fixed angle. Specifically, the wireless power supply unit 23 is manually held to alternately approach and move away from the position where the wireless power supply 22 is buried under the skin, so as to intermittently trigger the charging of the wireless power supply 22. Therefore, when the wireless power supply 22 is powered on, the ring body 14 is actively driven to rotate, and when the wireless power supply 22 is powered off, the ring body 14 is passively driven by the elastic coil 16 to rotate, and so on and so forth, thereby driving the brush rod 15 to repeatedly scrape and clean the inner wall of the inner cavity 3. When the wireless power supply unit 23 is kept close to the position where the wireless power supply 22 is buried under the skin, the wireless power supply 22 is continuously charged, and is driven by the drive unit 19, the gear 20 and the gear ring 21 to actively rotate the ring body 14 to the limit position, and the elastic roll 16 is also continuously tightened to the limit position along its spiral direction. When the non-destructive puncture needle 24 is inserted into the inner cavity 3, the inner end of the above-wound elastic roll 16 is tightly wrapped around the outer wall of the non-destructive puncture needle 24. At this time, if the needle tip of the non-destructive puncture needle 24 is bent to a certain extent, the non-destructive puncture needle 24 can be slowly pulled up so that the non-destructive puncture needle 24 can be corrected and straightened under the squeezing action of the inner wall of the tightly wound elastic roll 16, thereby avoiding the subsequent problem of the needle tip hooking the injection seat 1.

[0044] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
