【考案の詳細な説明】
本考案は、液体の流量調節器、特に静脈注射の
ための液体流量調節器に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid flow regulator, particularly for intravenous injection.
静脈注射は、身体のコンデイシヨンが比較的弱
い患者に対する重要な医療方法としてよく知られ
ている。 Intravenous injection is well known as an important medical method for patients with relatively weak physical conditions.
患者に薬液治療を施す場合、薬液の量や流速
は、患者の年令、病状や薬液の種類によつて適宜
決定しなければならない。 When administering medicinal treatment to a patient, the amount and flow rate of the medicinal solution must be appropriately determined depending on the patient's age, medical condition, and type of medicinal solution.
静脈注射のために通常使用される装置は、第９
図示のように主として液瓶、プラグ、長い塩化ビ
ニールチユーブ、一対の注射針、流量調節器から

流量調節器、第２注射針の順に流れ、患者の静脈
内に流入する。その液体の流量は、流量調節器に
よつて個々の患者の身体のコンデイシヨンに適応
するように調節される。 The equipment commonly used for intravenous injections is the 9th
As shown in the figure, it mainly consists of a liquid bottle, a plug, a long vinyl chloride tube, a pair of injection needles, and a flow rate regulator. In this device, a first injection needle is inserted into the interior of the liquid bottle through a plug attached to the outlet of the liquid bottle filled with the desired liquid, and one end of the PVC tube is connected to the first injection needle. the other end is connected to a second injection needle, and a flow regulator is mounted at a suitable position on the tube between the first and second injection needles. and,
While the tube is pressed, the liquid flows from the liquid bottle to the first injection needle, the vinyl chloride tube,
The flow goes through the flow regulator, the second injection needle, and into the patient's vein. The flow rate of the liquid is adjusted by a flow regulator to suit the individual patient's physical condition.
しかしながら、静脈注射を受けた患者の経験に
よれば、従来の調節器は、調節範囲に多少の限界
があり、極めて弱く、しかもゆつくりした流量率
の静脈注射を必要とする患者には適さない。その
上、従来の調節方法は、塩化ビニールチユーブが
流量調節器によつて直接押圧されるので、同チユ
ーブの押圧個所の断面形状が容易に変形してしま
う。そのため、従来装置では、所望の流量に調節
しても、その後時間の経過に伴つて流量が変化し
てしまい、所望の流量を得るのはむずかしい。 However, the experience of patients receiving intravenous injections has shown that conventional regulators have some limitations in their range of adjustment and are not suitable for patients who require intravenous injections with extremely weak and slow flow rates. . Furthermore, in the conventional adjustment method, the vinyl chloride tube is directly pressed by the flow rate regulator, so that the cross-sectional shape of the tube at the pressed location is easily deformed. Therefore, in conventional devices, even if the flow rate is adjusted to a desired value, the flow rate changes over time, making it difficult to obtain the desired flow rate.
薬液の流量は、時間が経過しても一定に維持さ
れることが望ましいので、上記ローラークランプ
では、看護婦や付添人などが常時点滴状態に気を
配り、流量の変化が激しいならば、流量を再びセ
ツトし直す必要があつた。 It is desirable for the flow rate of the drug solution to remain constant over time, so with the roller clamp mentioned above, nurses and attendants should always pay attention to the dripping state, and if the flow rate changes rapidly, the flow rate should be adjusted. It was necessary to set it again.
本考案は、上記従来の欠点を除去しようとする
ものである。 The present invention attempts to eliminate the above-mentioned conventional drawbacks.
本考案の主目的は、液体の流量を所望の流量に
簡単に設定でき、しかも最初に設定した流量を長

にある。 The main object of the present invention is to provide a liquid flow rate regulator that can easily set the liquid flow rate to a desired flow rate and maintain the initially set flow rate for a long period of time.
本考案の別の目的は、ゴムホースの外周の一部
に、調節中ゴムホースが直接押圧されるのを防ぐ
ゴムリングを巻き付けてある液体の流量調節器を
提供することにある。 Another object of the present invention is to provide a liquid flow rate regulator in which a rubber ring is wrapped around a part of the outer circumference of the rubber hose to prevent the rubber hose from being directly pressed during adjustment.

A pair of threaded tongue pieces 11 and 12 protrude from the end surface 15 so as to form a recess 13 in the extending direction of the end surface 15.
and a protrusion 14 protruding from the end surface 15 on the inside of the tongue pieces 11, 12. Second cylindrical body 2
is hollow, and has a threaded inner wall 211 at one end 21 as shown in FIG. 5, and a closed end surface 22 at the other end. The annular component 3 has a through hole 311 on one end surface 31 and is open on the other end surface 32. The control rod 4 has an enlarged end 41 at one end and a concave end 42 at the other end. The control rod 4 is inserted into the annular part 3 from the open end surface 32 so as to be movable back and forth, and has a concave end 42 as shown in FIG.
passes through the through hole 311 and the enlarged end 41 prevents the control rod 4 from sliding out of the through hole 311, so that the control rod 4 is retained in the annular part 3. The annular component 3 incorporating the control rod 4 in this manner is inserted into the second cylindrical body 2 from the end 21 of the second cylindrical body 2, and is inserted into the opening end surface 32 of the annular component 3.
is firmly supported inside the second cylinder 2 by being fixed to the closed end surface portion 22 of the second cylinder 2. Since the enlarged end portion 41 of the control rod 4 is in contact with the closed end surface portion 22 of the second cylinder 2 at one point, the friction between the control rod 4 and the closed end surface portion 2 is reduced, and the control rod 4 is becoming easier to move.

A rubber ring 6 is wrapped around the control rod 4 to prevent it from being directly pressed by the control rod 4. A hard rubber rod 8 is inserted into the interior of the rubber hose 5, forming a narrow passage for precise liquid flow control. The rubber ring 6, rubber hose 5, and hard rubber rod 8 are made of a rubber material of quality suitable for medical use. A pair of connectors 9, 9 are attached to both ends of the rubber hose 6 to ensure a good connection. When the rubber rod 8 contacts the connectors 9, 9, cutting portions 81, 81 are provided at both ends of the hard rubber rod 8 so as not to stop the flow of fluid within the rubber hose 5.

流量が得られる。 Next, the manner of use of the above flow rate regulator will be explained based on FIGS. 4 and 5. The second cylindrical body 2 is screwed onto the threaded inner wall 211 and the threaded tongue pieces 11 and 12. It is coupled to the first cylindrical body 1. Then, the rubber hose 5 is held together with the rubber ring 6 by the control rod 4 and the protrusion 14. User is second
Turn the cylindrical body 2 appropriately to connect the second cylindrical body 2 to the first cylindrical body 1
When the control rod 4 is moved toward , the enlarged end 41 of the control rod 4 is pushed by the closed end surface 22 of the second cylinder 2, and the rubber ring 6 is pressed by the concave end 42 of the control rod 4. , the desired liquid flow rate in the rubber hose 5 is obtained.
