器具に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that protects a combined structure (bioterminal) of a contact body embedded in skin tissue and a connecting body that connects the inside and outside of a living body.
従来のpercutaneou's electrode connector（経

等として使用されるものである。 Conventional biomedical terminals such as percutaneou's electrode connector (terminal with percutaneous electrode) and cannula (intubation) are placed on the skin of the living body and the other end is buried under the skin, and can monitor blood pressure, blood flow rate, temperature, electrocardiographic signals, etc. It is used as an electrical terminal for retrieving various biological information, or as an inlet for injecting infusions, various medicinal solutions, etc. through its through-hole, or as a retrieval/injection port for blood flow for artificial kidney dialysis, etc. .
従つて、その材質は、生体との接触部分におい

好ましいものである。特に水酸アパタイトは生体
組織に対して親和性に優れており、上記利用に
は、最適である。 Therefore, it is preferable that the material has as much biocompatibility as possible in the portion that comes into contact with the living body. In particular, hydroxyapatite has excellent affinity for living tissues and is optimal for the above uses.

提供することにある。以下、本考案を実施例によ
り詳細に説明する。 After such a bioterminal is implanted, approximately two weeks are required for it to be firmly and tightly attached in order to fully perform its function. It is difficult to keep the living body immobilized during this period, and the fixation time becomes even longer when the living body is active. In addition, rapid body movements and rocking of the external connector cause distortion between the contact body and the skin tissue, increasing the risk of bacterial infection. This kind of point continues to have some possibility even after fixation, and in response to sudden physical fluctuations, distortion occurs between the skin tissue and the contact body as before fixation, and this part The risk of tissue infection is greater. In view of the above, it is an object of the present invention to provide a biological terminal protection device that prevents as much as possible direct external force applied to the biological terminal and indirect external force applied through the connecting body. Hereinafter, the present invention will be explained in detail with reference to examples.

る。 In FIGS. 1, 2, 3, and 4, a connecting body opening 13 through which a connecting body extending from the contact body is passed is provided at the center of the hemispherical side wall portion 12. . In addition, vent holes 14 are provided at various locations in order not to impede skin breathing on the surface of the living body covered by this protective equipment. At the contact portion between the side wall portion 12 and the skin surface, there is a side wall portion 1
An enclosure bottom 11 made of the same material as 2, preferably a sweat-absorbing and flexible material, is integrally joined. Further, a stretchable fixing band 15 is applied to the skin surface for pressing and fixing the surrounding body consisting of the side face part 12 and the bottom part 11 of the surrounding body.

The number of vent holes 14 provided in 2 may be increased or decreased depending on each part of the living body.
Note that although the side surface portion 12 of the surrounding body has a hemispherical shape, it may have a cubic shape or the like.
以上から明らかなように、本考案は多様な形状
構造及び寸法をとり得るものであつて特定形態に
限定されるものではない。 As is clear from the foregoing, the present invention can take on a variety of shapes and sizes, and is not limited to any particular form.

なる効果を有するものである。 Therefore, the present invention can fix the connecting body extending from the contacting body in the vicinity of the contacting body, and can prevent indirect forces such as movement of the connecting body from being applied to the contacting body. In addition, since the surrounding body side part 12 blocks external force directly applied to the bioterminal,
It has great effects in use, such as promoting the adhesion of the contact body and further improving the stability of the bioterminal consisting of the contact body and the connecting body to the skin tissue.

The side wall portion 12 of the enclosure body is made of polyethylene material and has a hemispherical shape with one connecting body port 13 and four ventilation holes 14. Furthermore, the part that comes into contact with the skin, ie, the bottom part 11 of the surrounding body, was formed of sponge. Furthermore, a contact body made of apatite and a connecting body made of a conducting wire with a temperature measurement sensor attached to the tip were prepared. Here, the diameter of the connecting body is 5
mm, the height of the contact body is 20 mm, the bottom diameter is 15 mm, the bottom diameter of the enclosure of the biologic terminal protector of this invention is 30 mm, the height is
It was 15mm. After a bioterminal consisting of a contact body and a connecting body is penetrated and buried in the chest of an adult dog, a surrounding body consisting of a side face part 12 and a bottom part 11 of the body is placed, and a fixing band 15 such as a bandage is placed over this body. I guessed.

体と皮膚組織の間に出血が頻繁に生じた。 Approximately one week after the surgery, the contact surface between the contact body and the skin tissue became strongly bonded and could not be removed even by pulling, making it possible to successfully measure the body temperature of the living body probe over a long period of time. On the other hand, the contact body and its accompanying parts. When only the lead wire (connecting body) was inserted into the chest of an adult dog, the skin tissue and the contact body were fixed in close contact for two weeks after the surgery, but after that, due to the adult dog's body movements, the contact body and the skin tissue became loose. Bleeding occurred frequently.
