Description

Infusion port puncture fixator

Technical Field

The utility model relates to the field of medical auxiliary equipment, in particular to an infusion port puncture fixator.

Background Art

A fully implantable intravenous port (PORT) is a central venous infusion device that can be placed subcutaneously and remain in the body for a long time. It can be used for the infusion of various irritant drugs, long-term nutritional support, blood transfusion and other treatments. It can also be used for blood sample collection. By using a non-destructive needle to puncture the infusion port, an infusion channel can be established, reducing the pain and difficulty of repeated venous punctures. It is currently the world's preferred in vivo intravenous infusion device. See Figure 1, which is a fully implantable intravenous port 1, including a venous catheter 11, an infusion seat 12, an injection seat 13 above the injection seat 12, and a puncture diaphragm 14 is provided in the injection seat 13. The infusion port is implanted in the human body. When infusion is needed, connect the non-damage needle, heparin cap and 20 ml saline syringe to drain the fluid, palpate with the non-dominant hand, find the injection port, confirm the edge of the injection port, fix the injection port with the thumb, index finger and middle finger of the non-dominant hand to make an equilateral triangle, arch the injection port, determine the midpoint of the three fingers, and gently insert the puncture septum 14 vertically from the center of the injection port. During puncture and needle removal, it is fixed by manipulation. The infusion port currently used has the following disadvantages: 1. After the three fingers are fixed, the field of view is limited; it is difficult to find the center point of the puncture septum during puncture with a non-damage needle, and needle stick injuries are prone to occur during puncture and needle removal, which can easily cause puncture failure, affect the patient's medication, catheter blockage, lead to poor infusion, infection and other problems; 2. The injection port is relatively small. If an obese patient is encountered, it is difficult to fix during puncture, which reduces the success rate of infusion port puncture; repeated punctures increase the patient's pain, cause damage to the injection port and skin, and induce catheter-related bloodstream infection and other related complications.

The application number is 201910432707.2, which discloses an infusion port injection seat fixing device, which can prevent the infusion port injection seat from moving under the patient's skin, prevent the infusion needle from piercing the upper edge of the infusion port injection seat, and effectively ensure that the infusion needle can be inserted smoothly. However, it has the following disadvantages: the operating finger cannot be kept away from the injection seat, which may easily lead to the risk of needlestick injury.

Without a clear puncture range, it is impossible to ensure successful puncture with one needle.

In view of the deficiencies in the prior art, the purpose of the utility model is to provide an infusion port puncture fixator which has a simple structure, is easy to assemble and disassemble, effectively solves the problem of difficult fixation of the infusion port injection seat, achieves successful one-needle puncture, and effectively avoids needlestick injuries.

The above technical purpose of the utility model is achieved through the following technical solutions: an infusion port puncture fixator, including a fixing seat, an extended fixing wing is provided on the outer side of the fixing seat, a puncture hole is formed in the middle of the fixing seat, the fixing seat includes a fixing large circular ring, the inner side of the fixing large circular ring is connected to a puncture small circular ring through a connecting rib, the puncture small circular ring is provided with a first opening, and the inner side of the puncture small circular ring is the puncture hole.

In one embodiment: the fixed large circular ring is provided with a second opening, the second opening is larger than the first opening, and the fixed large circular ring and the puncture small circular ring are both concentric circle structures;

In one of the embodiments: the fixed large circular ring matches the edge diameter of the infusion seat injection seat.

In one embodiment, the extended fixed wings are in the shape of butterfly wings and are symmetrically distributed on both sides of the fixed large circular ring.

The fixing device is made of ABS resin material.

In summary, the utility model has the following beneficial effects:

First, the structure is simple and easy to disassemble and assemble. It is fixed by tools. The index finger and thumb of the non-dominant hand fix the extended fixing wing to effectively fix the infusion seat to prevent the movement of the injection seat and the failure of the non-damaged needle to puncture the puncture septum. The area within the puncture small ring is the puncture hole range, and the puncture hole range is the puncturable area of the infusion port puncture septum. The puncture hole clearly realizes a successful puncture with one needle, which reduces the patient's pain, improves the patient's satisfaction, and provides patients with professional and high-quality nursing services.

Second, to avoid repeated punctures due to unsuccessful punctures, which may damage the injection port and local skin, causing port exposure, secondary catheter bloodstream infection and unplanned catheter removal; and to eliminate nurses' fear of the non-damaged needle on the infusion port;

Third, the operating field of view becomes larger, which can effectively prevent nurses from needlestick injuries and reduce the risk of blood-borne occupational exposure.
