Description

Implantable infusion port protective positioning device

technical field

The utility model relates to the field of medical equipment, in particular to an implanted transfusion port protective positioning device.

Background technique

The implantable central venous port is a vascular access device that can be completely implanted in the patient and used repeatedly for a long time. After the rehydration, the removal of the central venous port is the last link in the use and maintenance of the venous port. The traditional method of pulling out the butterfly wing non-injury needle in the infusion port resulted in many needle stick injuries, which greatly increased the chance of infection for nurses. Therefore in order to reduce needle stick injury, the device that prevents needle stick injury occurred.

Patent Document 1, Implantable infusion port puncture positioner: application number, 201520552844.7, an implantable infusion port puncture positioner, including a transparent sheet, the shape of the transparent sheet is consistent with the shape of the injection seat top surface of the implantable infusion port Same, the size of this transparent sheet is slightly larger than the size of the top surface of the injection seat, there is a hole in the center of the transparent sheet, the shape and size of this hole are the same as the shape and size of the puncture septum on the top surface of the injection seat. When puncturing the implanted infusion port, the operator pinches the edge of the puncture positioner with the fingers of the left hand, and at the same time finds the subcutaneous injection seat of the patient by touching the fingers, confirms the edge of the top surface of the injection seat, and makes the outer edge of the puncture positioner in line with the injection site. The outer edge of the top surface of the seat coincides, the hole in the center of the puncture positioner is aligned with the puncture septum on the implanted infusion port, and the non-invasive needle is pierced through the hole in the center of the puncture positioner to complete the puncture operation. The positioning of the puncture operation is easy and accurate.

Patent document 1 can play a better positioning role, and the accuracy of puncture is high, but when the non-damaging needle punctures into the infusion port, the locator cannot be removed, and it can only be removed after the non-damaging needle is pulled out. It is inconvenient to use and there are potential safety hazards, and at the same time, the infusion port is easy to slide and deviate.

Patent document 2, safe needle puncture fixer for venous port without injury: application number, 201620310737.8, the utility model discloses a safe venous port non-injury needle puncture fixer, including a fixer body, characterized in that: the fixer body is The inner hollow ring, the top of the fixer body is an open end, the bottom of the fixer body is closed by a ring-shaped silicone membrane, and the center of the ring-shaped silicone membrane is provided with a puncture needle hole. Both sides of the main body are also provided with fixed wings and slots. The safe venous port non-damage needle puncture fixer provided by the utility model can allow nursing staff to easily fix the infusion port during puncture, improve the success rate of puncture and patient satisfaction, prolong the use time of the infusion port and reduce the risk of needle stick injuries for nursing staff , simple in structure and low in cost, and can be used as a disposable medical product.

Patent document 2 is a disposable product, which cannot be reused, and the infusion port still tends to slide and shift.

The technical solutions of Patent Document 1 and Patent Document 2 still cause stab wounds to the hands of the nursing staff when the non-damaged needle punctures and rebound occurs, and the protective effect on the nursing staff is not ideal.

Utility model content

The function of the isolation board is to isolate the nursing staff's fingers from the patient's skin, on the one hand to avoid slipping caused by sweat contact, and to avoid cross-contact infection at the same time.

It is further defined that the bottom surface of the C-shaped base, the inner wall of the C-shaped base, both sides of the isolation plate, the inner wall of the locking notch, and the inner wall of the C-shaped notch are all provided with a silicone layer.

The silicone layer has a skin-friendly effect, and at the same time, the silicone layer also increases the friction between the fingers and the C-shaped base, further achieving the anti-slip effect.

It is further defined that a clasp is provided at each notch of the locking position, and the clasp is fixed on the side of the C-shaped base, and the clasp is matched with a finger.

The C-shaped base and the fingers are fixed together, and the working reliability is greatly improved.

It is further defined that the snap ring is made of elastic hard material, the snap ring is an unclosed ring, the axis of the snap ring at the first notch is perpendicular to the horizontal plane, and the axis of the snap ring at the second notch is perpendicular to the horizontal plane. The axis is parallel to the horizontal plane.

The deformation ability of hard materials is poor, so it is designed as an unclosed ring structure to increase its adaptability.

It is further defined that each position of the locking notch is provided with a protective plate, the protective plate isolates the locking notch and the puncture opening, the protective plate is a curved surface structure, and the protective plate is close to the position of the locking notch The face is concave.

When the non-destructive needle rebounds or deviates, the needle tip is blocked by the protective plate to prevent the needle from sticking to the finger.

It is further defined that the upper surface of the C-shaped notch is provided with a positioning mark.

It is convenient to find the center position when piercing.

Further defined, there is a working inner wall between the bell mouth and the puncture opening, and the working inner wall has a cylindrical structure or a conical structure.

Adapts to the shape of most infusion ports today.

The beneficial effects of the utility model are as follows: the infusion port is fixed laterally through the C-shaped base, avoiding the lateral sliding and offset of the infusion port, ensuring the reliability of acupuncture, and making the infusion port It is stuck in the C-shaped base, just pinch and press down when using it. If there is only a C-shaped base, it can only be fixed laterally. It is inconvenient for the nursing staff to use force, and the non-destructive needle is easy to shift and slip. Through the structure of the bell mouth, the infusion port can be quickly and accurately found and fixed, which improves the work efficiency. The slipping of the device is avoided through the setting of the clamping gap and the collar, and the setting of the protective plate effectively avoids The finger was stabbed.
