Description

Technical Field

[0001] The utility model relates to an infusion port puncture fixator. Background Art

[0002] An infusion port (PORT) is a closed infusion device that is completely implanted in the human body. It is a closed venous infusion system that is completely buried subcutaneously and remains in the body for a long time. The infusion port consists of a catheter with the tip located in the superior vena cava and an injection seat buried subcutaneously. Depending on the implantation site, it can be divided into two types: chest wall infusion ports and arm infusion ports. It can be used for drug infusion, fluid replacement, nutritional support therapy, blood transfusion, blood sample collection, etc. After the patient undergoes local anesthesia, the medical staff makes a small incision in the patient's chest to implant the catheter, makes a pouch, implants the injection seat subcutaneously, and inserts the connected catheter into the central vein.

[0003] However, when medical staff use a special non-invasive needle for puncture in the later stage, they need to pinch the infusion port buried under the skin with one hand to fix its position, and use the other hand to hold the special non-invasive needle for puncture or pull out the special non-invasive needle. This method makes the fixation of the infusion port more difficult, time-consuming and labor-intensive. Utility Model Content

[0028] Please refer to Figure 1-2The present invention provides an infusion port puncture fixator, including a fixator body 10 and a fixing member 12. The fixator body 10 is provided with a fixing opening 11, which is an opening extending from the center of the fixator body 10 toward the outer side. The number of the fixing members 12 is preferably three, and these fixing members 12 are arranged around the circumferential direction of the fixing opening 11 to cooperate with the fixing opening 11 to form a fixing area for clamping the infusion port. Of course, the number of the fixing members 12 can also be specifically set according to actual production needs.

[0029] When in use, press the port puncture fixator to clamp the port puncture fixator on the subcutaneous port. Figure 1-2 The port is securely fixed within the designated area by aligning the fixed opening 11 with the top of the injection seat and the catheter, and each fixing member 12 with the outer edge of the subcutaneous infusion port. The port puncture fixture effectively improves the port's securement, saving time and effort.

[0030] For specific implementation, please refer to Figure 1-2 The fixture body 10 is preferably circular, but can also be triangular, square, or polygonal. The fixing opening 11 includes a circular portion near the center of the fixture body 10 and a fan-shaped portion near the outer side. This arrangement of the fixing opening 11 facilitates alignment with the top of the injection seat and the position of the catheter. The aforementioned fixing members 12 are primarily arranged around the circumference of the circular portion.

[0031] Please refer to Figure 2-5 Each fixing member 12 is preferably a strip extending downward from the bottom surface of the fixing body 10. These fixing members 12 are arranged around the circular portion of the fixing opening 11 and can correspond to the outer edge position of the infusion port, so that the infusion port can be clamped and fixed in the fixed area.

[0032] Please refer to Figure 3-5 Each fixing member 12 has a fixing end 13 and a clamping end 14. The fixing end 13 is connected to the fixing body 10, and the clamping end 14 is a free end used to clamp the infusion port. That is, the clamping end 14 corresponds to the outer edge position of the infusion port, so that the outer edge of the infusion port is clamped by the clamping ends 14 of multiple fixing members 12 together.

[0033] In one embodiment, please refer to Figure 3-5 The bottom of the holding end 14 of each fixing member 12 has a chamfered structure (not shown in the figure). The fixing member 12 arranged in this way can improve the comfort when its holding end 14 contacts the patient's skin and avoid damage to the patient's skin.

[0034] Please refer to Figure 3-5Each holding end 14 has a clamping portion. In one embodiment, each clamping portion is an arc-shaped structure formed by bending the bottom of each holding end 14 toward the fixing area. That is, the clamping portions of the holding ends 14 of multiple fixing members 12 are retracted inward together, further improving the fixation of the infusion port. In another embodiment, each clamping portion is a clamping protrusion 15 formed by protruding from the inner surface of each holding end 14 toward the fixing area. Specifically, the clamping protrusion 15 can be spherical, bar-shaped, or other structures. With such a fixing member 12, the clamping portion can improve the contact effect with the subcutaneous infusion port, preventing relative sliding between the clamping portion and the infusion port, thereby further improving the fixation of the infusion port.

[0035] Please refer to Figure 2-5 The material of each fixing member 12 is preferably elastic plastic. Such a configuration of the fixing members 12 not only improves the comfort when in contact with the patient's skin, but also facilitates the expansion and contraction of the fixing members 12, thereby improving the fixation effect of the infusion port. A more preferred embodiment is that the fixator body 10 and the fixing members 12 are made of an integral molding, and the entire body is made of elastic plastic, which greatly improves the comfort of the infusion port puncture fixator when in contact with the patient's skin. Among them, the elastic plastic is preferably silicone, which not only improves comfort but also has an anti-slip effect. Of course, the elastic plastic can also be a thermoplastic elastomer, a polyurethane elastomer, a rubber plastic, etc.

[0036] Please refer to Figure 1-5 The infusion port puncture fixator further includes a handheld portion 16, which is disposed on the fixator body 10. When in use, the handheld portion 16 can be used to press the fixator body 10 and its fixing member 12 to fix the infusion port, thereby improving the pressing efficiency.

[0037] The handheld portion 16 may be provided in at least two embodiments:

[0038] The first implementation method is to refer to Figure 1-5 The handheld portion 16 is preferably a rod. Specifically, the handheld portion 16 can be arranged on the holder body 10 in a horizontal direction or a vertical direction, that is, the handheld portion 16 can be arranged horizontally, vertically or tilted relative to the holder body 10 to meet different force application and production requirements. Figure 3 The handle 16 can be a rod formed by extending horizontally from the outer side of the holder body 10 away from the center, or, please refer to Figure 4 The handle 16 is a rod extending upward from the top surface of the holder body 10, or, please refer to Figure 5The grip portion 16 is a rod extending diagonally away from the center of the holder body 10 from its outer portion. The rod may also be provided with an anti-slip structure to prevent slipping. The anti-slip structure may be a non-slip sleeve or a plurality of anti-slip protrusions protruding from the rod surface. The anti-slip protrusions may be spherical, strip-shaped, or other structures. During use, a medical professional can control the holder body 10 and its fixing member 12 by gripping the rod, allowing the professional's hand, which is used to press the port puncture holder, to maintain a sufficient distance from the port, thus preventing injury to the professional's hand during needle removal.

[0039] The second implementation method is to refer to Figure 1-2 The grip portion 16 is an arcuate groove (not shown) formed by the top surface of the fixing body being recessed toward the bottom surface. This arrangement of the grip portion 16 provides a simple structure and is easy to manufacture. During use, a medical professional can control the fixator body 10 and its fixing member 12 by placing their hand within the arcuate groove. The arcuate groove is preferably located on the outer side of the fixing body, allowing the medical professional's hand, which is used to press the port puncture fixator, to maintain a certain distance from the port, thereby preventing injury to the medical professional's hand during needle removal.

[0040] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
