This provides significant convenience for operators and is suitable for drug administration and bodily fluid collection, especially for animal drug administration and bodily fluid collection.

Description

Technical Field

[0001] This utility model relates to the field of infusion port technology, and in particular to a drug delivery port for collecting and administering body fluids. Background Technology

[0002] In the prior art, an infusion port (implantable intravenous drug delivery device) consists of a port body, a catheter, and an external infusion assembly. The port body is implanted subcutaneously and communicates with a catheter placed in a blood vessel. The external infusion assembly includes components such as an infusion port needle, an infusion tubing, and a bottle stopper puncture device. In use, the infusion port needle is inserted into the port body from outside the body, punctures and passes through the skin, and communicates with the catheter, thereby achieving communication with a vein, facilitating drug delivery and collection of body fluids.

[0003] In existing technologies, the port body of an infusion port is completely implanted subcutaneously. The implantation process involves first separating the subcutaneous tissue, then creating a pocket-shaped area, placing the port body into this area, and securing it to the muscle. The entire port body is then covered with skin and sutured. During subcutaneous implantation, the subcutaneous tissue is separated using blunt force with instruments, which can easily cause subcutaneous injury and fluid accumulation, and may also lead to tissue hyperplasia around the port, thus interfering with the insertion of the infusion needle. Furthermore, since the infusion needle needs to penetrate the skin to be inserted into the port body, there is a risk of contamination of the needle with blood or other bodily fluids during the penetration process, hindering the collection of bodily fluids and easily contaminating the collected fluids. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a port for collecting and administering body fluids, wherein the port seat is embedded in the skin, while its connecting section is located outside the body, and the infusion port needle is inserted into the port body from outside the body.

[0005] The drug delivery port for body fluid collection and administration provided by this utility model includes: The harbor body is formed as a columnar body; the bottom of the harbor body is a harbor seat, which is embedded under the skin; the top of the harbor body is a connecting end, which is exposed outside the skin; the radial dimension of the middle section of the harbor body is smaller than the radial dimension of the harbor seat and smaller than the radial dimension of the connecting end; the harbor body has a channel, one end of which is opened at the connecting end. A flexible plug is mounted on the base and communicates with the other end of the channel; A top cover is disposed on the connecting end, the top surface of the top cover having a space between it and the connecting end for accommodating the puncture membrane, and the top cover pressing the puncture membrane against the connecting end, the top surface of the top cover having an opening for exposing the puncture membrane for puncture.

[0006] Preferably, the bottom surface of the pedestal extends radially to form a step, and the step has an axial fixing hole for fixing the pedestal to the muscle.

[0007] Preferably, the channel is L-shaped, including a vertical portion extending axially along the harbor body and a transverse portion extending radially along the harbor seat.

[0008] Preferably, the hose plug is mounted radially on the transverse portion.

[0009] Preferably, the hose plug is connected to the transverse portion by a thread.

[0010] Preferably, the central axis of the opening on the top surface of the upper cover is coaxial with the central axis of the vertical portion.

[0011] Preferably, the radial dimension of the opening on the top surface of the upper cover is greater than the radial dimension of the vertical portion.

[0012] Preferably, the top cover is connected to the connecting end by fasteners and / or threads.

[0013] Preferably, the circumferential outer edge of the harbor is transitioned by a chamfer or an arc.

[0014] Preferably, the puncture membrane is a silicone puncture membrane.

[0015] This invention provides a port-of-care for fluid collection and administration. The port seat is implanted under the skin, with a thinner middle section passing through the skin and the connecting end exposed externally. A top cover presses the puncture membrane against the connecting end, facilitating the infusion needle to puncture the membrane through the opening in the top cover and extend into the channel. This allows for connection to a catheter placed in a blood vessel via a flexible plug without skin puncture, eliminating the possibility of subcutaneous blood contamination. Furthermore, the port seat of this invention does not require expanding the pocket-shaped area, effectively reducing subcutaneous fluid accumulation and tissue hyperplasia. Simultaneously, the skin also limits the middle section, preventing the port-of-care from shifting. This invention provides a port-of-care for great convenience to operators and is suitable for drug administration and fluid collection, especially for animal drug administration and fluid collection.

A flexible plug is mounted on the base and communicates with the other end of the channel; A top cover is disposed on the connecting end, the top surface of the top cover having a space between it and the connecting end for accommodating the puncture membrane, and the top cover pressing the puncture membrane against the connecting end, the top surface of the top cover having an opening for exposing the puncture membrane for puncture.

[0020] In this embodiment of the invention, the port seat is implanted under the skin. After passing through the skin via a thinner middle section, the connecting end is exposed outside the body. The top cover presses the puncture membrane tightly against the connecting end. The infusion port needle punctures the puncture membrane through the opening of the top cover and extends into the channel, thereby connecting with a catheter placed in the blood vessel via a flexible plug. This invention achieves communication between the infusion needle and the catheter without piercing the skin, eliminating the possibility of subcutaneous blood contamination. Furthermore, the port seat of this invention does not require expanding the pocket-shaped area; simply cut the skin, place the port seat directly into the middle of the incision, fix it to the muscle, and then suture the skin. This effectively reduces subcutaneous fluid accumulation and tissue hyperplasia. Additionally, the skin also limits the middle section, preventing the port from moving freely. The infusion port provided by this invention offers great convenience to operators and is suitable for drug administration and body fluid collection, especially for drug administration and body fluid collection in animals. It should be noted that the radial dimension of the middle section is smaller than the radial dimension of the port and smaller than the radial dimension of the connecting end. This means that the middle section is thinner, while the port and connecting end are thicker. The thinner middle section is to minimize the opening in the skin. The radial dimension of the middle section is preferably larger than the inner diameter of the channel. Preferably, the connecting end, middle section and port of the drug port are all cylindrical. The parts with different radial dimensions (diameter in this case) are transitioned by chamfers or arcs to improve comfort.

[0021] In one specific embodiment, the bottom surface of the port seat extends radially to form a step, and the step has axially spaced fixing holes for securing the port seat to the muscle. Understandably, this specific embodiment is intended to facilitate securing the port seat to the muscle, for example, by sewing the port seat to the muscle through the fixing holes.

[0022] In one specific embodiment, the channel is L-shaped, including a vertical portion extending axially along the port body and a transverse portion extending radially along the port seat. Preferably, the tubing plug is radially mounted to the transverse portion. More preferably, the tubing plug and the transverse portion are connected by a thread. Understandably, in this specific embodiment, the vertical portion of the channel is used to communicate with an infusion port, typically the infusion port extends into the vertical portion after passing through the puncture membrane, preferably extending to the bottom of the vertical portion where it communicates with the transverse portion, which facilitates drug administration or fluid aspiration.

[0023] In one specific embodiment, the central axis of the opening on the top surface of the upper cover is coaxial with the central axis of the vertical portion. Preferably, the radial dimension of the opening on the top surface of the upper cover is larger than the radial dimension of the vertical portion. This specific embodiment facilitates the insertion of the infusion needle. Preferably, the opening on the top surface of the upper cover is circular, and the vertical portion is cylindrical.

[0024] In one specific embodiment, the top cover is connected to the connecting end by fasteners and / or threads.

[0025] In one specific implementation, the circumferential outer edge of the portafilter is transitioned by a chamfer or a rounded shape. Understandably, since the portafilter is implanted under the skin, it is necessary to minimize the presence of sharp edges; preferably, chamfers or rounded transitions between different surfaces improve comfort and reduce potential tissue damage.

[0026] In one specific embodiment, the puncture membrane is a silicone puncture membrane. The silicone puncture membrane is, for example, capable of withstanding 1000 non-invasive punctures at 19G and / or 2000 non-invasive punctures at 22G.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
