フアイバセンサが必要とされる場合が多い。 Conventionally, optical fiber sensors have been used for various purposes as observation and measurement devices that use optical fibers that are small in diameter, flexible, and do not require electricity. Depending on the purpose of use of the fiber sensor, an optical fiber sensor is often required that includes an optical fiber and additional functional means as an integrated structure.

１３および薬物注入口１４とが分岐されている。 Figure 1 is a schematic external view of an example of a conventional optical fiber sensor for measuring cardiac output, and Figure 2 is A of Figure 1.
- It is a figure showing the A cross section. This optical fiber sensor is inserted into a biological blood vessel to carry out measurements, but the outer diameter of the resin that constitutes the optical fiber sensor is
The 2.3 mm tube 1 forms four independent passages along the axial direction inside the tube by an internal partition wall that is integrally formed with the outer circumferential wall of the tube.
These passages include a passage 2 for inserting an optical fiber 6, a passage 3 for transporting gas or liquid to inflate a guide balloon 7 for carrying the optical fiber sensor along the blood flow to a predetermined site within a blood vessel or heart; A passageway 4 for transporting a dye such as indocyanine green for measuring cardiac output based on the concentration and time change of the dye injected into the blood, and a passageway 4 equipped with a spout 8 and for transporting various other drugs. It functions as a passage 5 having a spout 9 at its end. In addition, an optical fiber sensor for in-vivo observation or measurement has a required length, for example, about 1200 mm in this example, in order to insert it into the in-vivo observation or measurement site, but this optical fiber sensor has a branch at its base. It has a mount 10, from which a balloon gas injection port 11, an optical connector 12, a dye injection port 13, and a drug injection port 14 are branched.

ユーブ１の外径を所定寸法の2.3mm以下とするこ
とが必要である。 As mentioned above, optical fiber sensors are often used by being inserted into living organisms, so it is necessary to make the outer diameter of the device as thin as possible.In this example, the outer diameter of tube 1 is set to 2.3 mm. It is necessary to do the following.
このような構造を有する光フアイバセンサを製

路を有するチユーブを所定外径寸法を有するよう
押出成形し、完成チユーブの内部通路の１つまた
は複数に光フアイバを挿入する方法をとつてい
た。 When manufacturing an optical fiber sensor having such a structure, conventionally, a tube having a desired number and shape of internal passages is extruded to have a predetermined outer diameter, and one or more of the internal passages of the completed tube is formed by extrusion. The method was to insert an optical fiber.
しかしながら、上記従来の方法ではチユーブ内
の光フアイバ挿入用通路断面積が小さくかつ光フ
アイバの挿入長さが大きいため可撓性を有する光
フアイバをチユーブ内通路に挿入することが困難
であつた。 However, in the above conventional method, the cross-sectional area of the optical fiber insertion passage in the tube is small and the insertion length of the optical fiber is large, making it difficult to insert a flexible optical fiber into the tube passage.

フアイバを光フアイバ通路内に円滑にかつ断面密
に挿入することは一層困難であつた。 In addition, in order to improve the measurement sensitivity of the optical fiber sensor, it is desirable that the sum of the cross-sectional areas of the optical fibers inserted inside the optical fiber sensor be as large as possible. It was necessary to insert it with a dense cross section. Furthermore, in order to improve the mechanical and chemical strength of the optical fiber, it is customary to apply a primary coat to the surface of the optical fiber, but when the optical fiber is a quartz fiber, the silicone resin that is generally used as the primary coat has a characteristic of poor slippage. This has the effect of impairing the slippage between the tube passage wall and the optical fiber when the optical fiber is inserted. Due to these additional reasons, it has been more difficult to insert the optical fiber smoothly and with a tight cross-section into the optical fiber passage.

測定感度の向上を目的としている。 The present invention was made for the purpose of improving the drawbacks in the conventionally known manufacturing method of optical fiber sensors, and it is an object of the present invention to improve the method of manufacturing optical fiber sensors. The purpose is to improve the measurement sensitivity of the optical fiber sensor by facilitating the insertion operation and increasing the sum of the cross-sectional areas of the optical fibers inserted.

変化させるために加熱行程を導入している。 In the method for manufacturing an optical fiber sensor according to the present invention, the cross-sectional area of a tube having an optical fiber insertion passage is kept in an enlarged state when the optical fiber is inserted, and the cross-sectional area of the tube is contracted to a state having a predetermined finished product size after the optical fiber is inserted. In order to achieve this, the tube that forms the structural member of the optical fiber sensor is made of heat-shrinkable material, and a heating process is also introduced to change the cross-sectional area of the tube.

成品を得ることができる。 As a result, when inserting an optical fiber into a passage within a tube, the cross-sectional area of the passage for optical fiber insertion is kept larger than the sum of the cross-sectional areas of the optical fibers to be inserted in proportion to the expansion of the cross-sectional area of the tube. The insertion resistance of the optical fibers can be reduced to facilitate insertion, and the sum of the cross-sectional areas of the inserted optical fibers can be increased, thus improving the measurement sensitivity of the optical fiber sensor. Furthermore, after inserting the optical fiber, the tube can be heat-shrinked to obtain a completed optical fiber sensor having predetermined dimensions.

態とする。 This tube 15 is crosslinked by irradiating it with an electron beam, and then heated and expanded to a desired tube diameter during the optical fiber insertion process, for example, an outer diameter of 4 mm in this example. The tube, which has been expanded to a desired size, is cooled and temporarily kept in a dimensionally stable state while maintaining the expanded size.

At this time, the cross-sectional area of the passageway 2 is expanded compared to the cross-sectional area in the finished product state (in this example, it is approximately three times larger). Therefore, despite the adverse conditions of long insertion length and poor slippage due to the primary coat of the optical fiber, it is extremely easy to insert the optical fiber in the finished product state so that the cross-section is dense with respect to the optical fiber passage. be.
