BACKGROUND OF THE INVENTION
The present invention relates to a holder for holding a temperature sensor inserted into the bag from the mouth of the bag.
[0002]
[Prior art]
When a bag containing liquid contents such as infusion is sterilized with warm water, it is necessary to monitor the temperature of the liquid contents of the bag.
At the time of sterilization treatment, a temperature monitoring bag is usually placed together with a bag for sterilization treatment, and a temperature sensor is inserted therein.
Explaining in detail how to insert the temperature sensor, cut a part of the bag, discharge the liquid inside, make small holes on both sides of the bag, and insert a holder to introduce the tip of the temperature sensor from the cut part. Install this holder and fix it with screws. The liquid content is put into the bag from the cut portion, the cut portion is welded, the temperature sensor is pushed from the mouth portion of the bag, and the tip is inserted into the hole of the holder.
[0003]
FIG. 4 is a side view showing a state in which the temperature sensor 11 is pushed from the mouth portion 14 of the bag 10 and the tip is inserted into the hole 13 of the holder 12.
FIG. 5 is an exploded perspective view of the holder 12. Male screws 12a project from both ends of the holder 12, and are secured with a seal ring 12b and a nut 12c with a bag interposed therebetween.
[0004]
[Problems to be solved by the invention]
In the above-described method, since the hole is formed in the bag and the holder is screwed, there is a possibility that the liquid content leaks from the hole and the temperature of the liquid content cannot be measured accurately.
Further, the temperature sensor is pushed and held in a hole opened in the shaft, but it is difficult to insert the temperature sensor into the hole.
Therefore, there is a demand for a holder structure that can reliably and easily set the temperature sensor without leaking liquid contents.
[0005]
[Means for Solving the Problems and Effects of the Invention]
(1) The temperature sensor holder of the present invention has a hollow portion for introducing the temperature sensor, a main body into which the tip end portion is inserted into the bag mouth from the inside of the bag, and the bag of the main body. A fixing tool for fixing the tip end portion of the temperature sensor formed on the side opposite to the tip end portion inserted into the mouth portion, and the fixing tool bag the tip end portion of the main body. The fixing tool is formed at a position away from the tip so that it does not come into contact with the mouth and is larger in diameter than the main body. (Claim 1). Since the temperature sensor holder having this structure is inserted into the bag mouth from the inside of the bag, it is not necessary to make a hole in the side surface of the bag, so that the temperature can be measured without worrying about liquid leakage. Further, the body Ri hollow der, it Ru can deploy a temperature sensor therein a guide. In addition, since a fixing tool having a diameter larger than that of the main body hollow portion is formed on the side of the main body hollow portion opposite to the portion inserted into the mouth portion of the bag, Even when the bag is placed on a flat surface, the thickness between both side surfaces of the bag can be secured, and the liquid can be introduced into the thickness. Therefore, the temperature measurement accuracy by the temperature sensor can be increased.
[0006]
If the cross-sectional shape of the main body is a circle, the temperature sensor holder can be easily inserted and inserted into the mouth of the bag.
It is preferable that the tip of the hollow portion of the main body is gradually narrowed. This makes it easy to position the tip of the temperature sensor led to the hollow portion.
It is preferable to have a plurality of holes on the side of the hollow body. This is because the liquid in the bag can freely flow through the hole, so that the temperature measurement accuracy can be increased.
[0007]
Solid Teigu is circular with a thickness that is preferably a disc shape. This is because the disc shape makes it difficult to damage the inner surface of the bag, and the length of the cut portion of the shoulder of the bag can be minimized.
[0008]
(2) Further, in the method for measuring the temperature of the liquid inside the bag of the present invention, the holder according to claim 1 is inserted into the bag mouth from the inside of the bag, the bag is filled with the liquid, and the bag mouth In this method, the temperature of the liquid inside the bag is monitored by inserting a temperature sensor into the bag.
The order of filling the liquid in the bag and inserting the temperature sensor into the bag from the mouth of the bag may be changed (claim 9).
[0009]
According to these method inventions, it is possible to reliably set the temperature sensor and measure the temperature without leaking the liquid contents.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a perspective view showing an appearance of a temperature sensor holder, and FIG. 2 is a cross-sectional view.
The temperature sensor holder 1 is made of a hard resin such as Teflon, and has a main body hollow cylinder 2 and a large-diameter fixing tool 3 connected to one end thereof. A hole 3a connected to the hollow portion 2a of the hollow cylinder 2 is formed at the center of the fixture 3, and the tip of the hole 3a is gradually narrowed to guide the tip of the temperature sensor.
[0011]
In addition, a large number of small holes 2b are formed on the side surface of the main body hollow cylinder 2 so that the infusion can freely flow.
FIG. 3 is a cross-sectional view of the main part showing a state in which the temperature sensor holder 1 is set in the infusion bag 4.
The mouth part 5 of the infusion bag 4 is made of polyethylene and has a cylindrical shape, and a rubber 6 is attached to the tip. The temperature sensor holder 1 is inserted into the cylindrical portion 5a of the mouth portion 5 from the inside of the infusion bag.
[0012]
The temperature sensor 7 is composed of a stainless steel tube and a thermocouple inserted therein. The temperature sensor 7 passes through the rubber 6 and passes through the inside of the temperature sensor holder 1, and the tip 7 a protrudes from the hole 3 a of the fixture 3 of the temperature sensor holder 1.
Next, a method for setting the temperature sensor holder 1 will be described.
The shoulder 9 of the infusion bag 4 is cut, and the infusion solution therein is discharged. The temperature sensor holder 1 is inserted from the cutting part 8, and the tip of the main body hollow cylinder 2 is inserted into the cylindrical part 5 a of the mouth part 5. The transfusion is refilled from the cutting part 8 and the cutting part 8 is welded. Next, the temperature sensor 7 is inserted from the mouth portion 5 so that the tip slightly protrudes from the fixture 3.
[0013]
The temperature sensor 7 may be inserted from the mouth part 5 and then the infusion solution may be filled to weld the cutting part 8.
Thus, the temperature monitoring bag 4 is completed.
If temperature is measured at the time of sterilization treatment with the bag 4 for temperature monitoring, the solution does not leak during measurement, and the temperature can be measured accurately.
Although the embodiments of the present invention have been described above, the embodiments of the present invention are not limited to the above-described embodiments. For example, as a structure of the temperature sensor holder, the main body may be solid rather than hollow. What is necessary is just to make a foam by making resin highly foamed and to insert a temperature sensor in this.
[0014]
The cross-sectional shape of the main body hollow portion is not limited to a circle, and may be any shape such as a quadrangle. However, the shape of the cylindrical portion 5a of the mouth portion 5 also needs to be matched with this.
In addition, various modifications can be made within the scope of the present invention.
