Abstract

The present invention is for easily and accurately targeting a port portion of a chemo port inserted subcutaneously from the outside of the skin, and comprises: a targeting main body portion disposed at a point on the skin corresponding to the insertion position of the chemo port before the infusion needle is connected to the port portion of the chemo port from the outside of the skin, and a target guide member including a connection guide portion formed at a position corresponding to the port portion and provided at the center of the targeting main body portion; and at least one magnet that generates magnetic force and a magnetic body provided in the casing portion of the chemo port (configured in a form that surrounds the port portion to support the port portion subcutaneously).

Claims (6)

  1. It is intended to easily and accurately target the port portion of the chemoport, which is inserted subcutaneously and where the infusion needle connects, even from the outer side of the skin. A target guide member comprising a targeting main body portion disposed at a point on the skin corresponding to the insertion position of the chemo port before the infusion needle is connected to the port portion side of the chemo port on the outer side of the skin, and a connection guide portion provided at the center of the targeting main body portion and formed at a position corresponding to the port portion; and It includes a magnetic body and at least one magnet generating magnetic force provided in the casing of the chemo port, which is coupled to the targeting main body and configured to support the port portion under the skin and position the port portion towards the center; The above magnetic body is composed of multiple units and is arranged at regular intervals around the casing portion, and The above magnets are formed in a number corresponding to the magnetic bodies and are arranged at positions corresponding to the magnetic bodies, and The above magnets consist of three elements spaced apart along the circumferential direction, and at least one of the three elements has a different polarity. The above magnetic body is a plurality of magnets having a polarity different from each of the above magnets, and A positioning targeter for a subcutaneous injection chemoport, characterized in that the magnet is provided on the contact surface of the targeting main body that contacts the skin and is respectively disposed on the corner side of the targeting main body.
  2. In paragraph 1, A positioning target for a subcutaneous injection chemo port, characterized in that the above-mentioned connection guide portion is formed in a shape corresponding to the above-mentioned port portion.
  3. In paragraph 1, A positioning target for a subcutaneous injection chemo port, characterized in that the above-mentioned connection guide portion is formed with a through-hole structure, and the surface defining the through-hole is formed to correspond to the plane of the above-mentioned port portion.
  4. In paragraph 3, A positioning targeter for a subcutaneous injection chemoport, characterized in that the connection guide part includes an interference prevention channel that communicates with the through hole and is open to the outside of the targeting main body part, so that the target guide member can be removed from the skin together with the magnet after the infusion needle is inserted into the port part of the chemoport through the connection guide part.

Description

Position designation targeter for hypodermic injection chemoport The present invention relates to a positioning target for a subcutaneous injection chemo port, and more specifically, to a positioning target for a subcutaneous injection chemo port with an improved structure that allows the position of the needle connection portion of a chemo port inserted subcutaneously to be easily and accurately located from the outside of the skin. Among the various methods of administering medication into the body, an intravenous injection involves inserting a needle into a blood vessel and injecting the liquid medication; under the Medical Service Act, this is permitted only when performed by skilled professionals in a hospital. Consequently, if you require an intravenous injection, you must endure the inconvenience of visiting a hospital. However, visiting a hospital every time an intravenous injection is required is inconvenient in itself. In particular, if accessibility to a hospital is poor, or if the patient has a walking disability or is unable to move at all, visiting the hospital becomes difficult; consequently, many patients give up on intravenous injections and take oral medications as an alternative. Oral medications have the advantage of allowing patients to take them at home for a long period without frequent hospital visits. However, not all medications can be produced in oral formulations. To address these issues, subcutaneous injection is being applied. Unlike intravenous injections, subcutaneous injections do not require expertise or proficiency in administration. This is because, unlike intravenous injections which require inserting the needle into the blood vessel in the correct direction and depth for proper administration, subcutaneous injections only require injecting the medication by puncturing the area anywhere, such as the abdomen, upper arm, buttocks, or thigh. Drugs administered by subcutaneous injection have advantages over oral administration, such as faster absorption into the body, non-action by digestive fluids, and non-detoxification by the liver during absorption. For these reasons, drugs such as insulin and anticoagulants are administered by subcutaneous injection. As mentioned above, since subcutaneous injections do not require specialized expertise, individuals often receive a prescription for the solution and administer it themselves at home. This is convenient because, despite being an injectable medication, there is no need to visit the hospital every day. On the other hand, long-term administration of medication via subcutaneous injection places a psychological burden and physical pain on the patient due to the need to be pricked by a needle every day. While there is convenience in administering injections, the pain of being pricked by a needle at least once a day can act as a factor that reduces patient compliance with treatment. To alleviate these disadvantages and the patient's suffering, a subcutaneous injection chemoport (10) as shown in Fig. 1 is sometimes used. In addition, people who have undergone long-term anticancer chemotherapy may have hardened blood vessels so that a needle cannot be inserted, or necrosis of the veins may occur due to the anticancer drug. Attempts are being made to overcome these side effects by inserting the above chemoport into a large central vein and maintaining it, and then injecting the drug through the chemoport, instead of frequently inserting a needle into the cancer patient's arm. A subcutaneous injection chemo port (10) is fixed to the patient's body and directs an injection fluid injected from the outside into its interior to a desired point in the subcutaneous layer. It includes an injection needle that is pre-inserted and fixed in the subcutaneous layer, and a body that supports the injection needle and has a flow path formed therein. When a practitioner injects the injection fluid into the flow path, the injection fluid passes through the flow path and is injected through the injection needle. However, since this type of subcutaneous injection chemo port is inserted into the body and is not visible, the location of the chemo port (10) is roughly confirmed by touch as shown in Fig. 1, and then a needle is inserted into it for use. In the case of children or thin patients, the needle connection part (the part where the infusion needle is connected) (11) is not easily confirmed by touch due to the use of a small chemo port, and in the case of obese patients, the chemo port is buried in the flesh and is not easily found. Prior art includes Registered Patent Publication No. 10-1502157. FIG. 1 is a diagram illustrating a method for determining the location of a chemo port according to the prior art. FIG. 2 is a perspective view illustrating a positioning target for a subcutaneous injection chemo port according to an embodiment of the present invention. FIGS. 3 and 4 are drawings illustrating a target guide member employed in an embodiment
