Description
【発明の詳細な説明】 本発明は輸液輸血セットの改良に関するものである。[Detailed description of the invention] The present invention relates to an improved transfusion set.
一般に輸液輸血セットは、添付図面に示すごとく、点滴
瓶の口部に刺し込むための針１、点滴筒３、注射針５及
びクランプ６から構成され、針１と点滴筒３及び点滴筒
３と注射針５はそれぞれ可撓性プラスチックチューブ２
，４で連結されていることはよく知られている。Generally, an infusion blood transfusion set is composed of a needle 1 to be inserted into the mouth of an IV bottle, an IV tube 3, a syringe needle 5, and a clamp 6, as shown in the attached drawing. Each injection needle 5 has a flexible plastic tube 2
, 4 is well known.
そして使用に際しては、針１を点滴瓶の口部に刺り込み
、流出する薬液や血液を一旦点滴筒３に貯溜し、クラン
プ６で流量を調整しつつ、その薬液等を注射針５から人
体に注入するものであるが、従来では流量が経時的に変
化するため、絶えずクランプ６で流量調節する必要があ
った。When in use, the needle 1 is inserted into the mouth of the IV bottle, the medical fluid and blood flowing out are temporarily stored in the IV tube 3, and while the flow rate is adjusted with the clamp 6, the medical fluid etc. is delivered from the injection needle 5 into the human body. However, in the past, since the flow rate changed over time, it was necessary to constantly adjust the flow rate with the clamp 6.
このため、従来クランプ６の底部に溝を設けるなどして
、流量を安定させるようにしたものも幾つか提案され市
販されているが、これらは溝等を設ける必要上コスト的
に高くなることは避けられない。For this reason, several conventional clamps 6 have been proposed and commercially available in which a groove is provided at the bottom to stabilize the flow rate, but these do not require high cost due to the need to provide the grooves. Inevitable.
また従来では使用中輸液輸血セットに加えられた衝撃を
緩衝させ注射針５に振動を伝えないようにするため、通
常、注射針５とチューブ４はゴム管７を介して接続して
いたものであるが、このようなゴム管７の取り付は作業
はきわめて面倒であり、製造能率を落す原因にもなって
いた。Furthermore, in the past, the injection needle 5 and the tube 4 were usually connected via a rubber tube 7 in order to buffer the shock applied to the transfusion set during use and to prevent vibrations from being transmitted to the injection needle 5. However, installing the rubber tube 7 in this manner is extremely troublesome and causes a drop in manufacturing efficiency.
本発明はこのような現状に鑑みて幾多の研究と検討を重
ねた結果提案されたものであり、特に点滴′笥３の下方
に接続される可撓性プラスチックチューブ４に着目し、
その内径を特定することで、クランプによる点滴保持率
を向上させ、安定した点滴流量を得ると共に、ゴム管を
不要にした新たな輸液輸血セットを提供しようとするも
のである。The present invention was proposed as a result of numerous studies and studies in view of the current situation, and focuses particularly on the flexible plastic tube 4 connected to the lower part of the drip tray 3.
By specifying the inner diameter, we aim to improve the drip retention rate by the clamp, obtain a stable drip flow rate, and provide a new infusion blood transfusion set that eliminates the need for a rubber tube.
ところで従来までは前記点滴筒３の下方に接続される可
撓性プラスチックチューブ４はその内径が２〜２．７朋
のものを使用しているが、このような内径のものでは上
記したごとく特殊なりランプを使用しないと点滴保持率
が下がることになる。By the way, conventionally, the flexible plastic tube 4 connected to the lower part of the drip tube 3 has an inner diameter of 2 to 2.7 mm, but as mentioned above, the flexible plastic tube 4 has an inner diameter of 2 to 2.7 mm. If a lamp is not used, the drip retention rate will decrease.
そこで本発明者等は前記チューブ４の内径を種々変えて
点滴開始後２時間までの点滴保持率と、クランプをフリ
ーにして１分間に落ちる滴数を調べてみた。Therefore, the present inventors varied the inner diameter of the tube 4 and investigated the drip retention rate for up to 2 hours after the start of drip infusion and the number of drops falling per minute with the clamp free.
実験で使用したセットは瓶刺込針１が外径１．６５ ｍ
ｍ、注射針５が２１ゲージ、チューブ肉厚が０．４ ｍ
ｍであり、試験液として蒸留水を使用した。In the set used in the experiment, bottle piercing needle 1 has an outer diameter of 1.65 m.
m, injection needle 5 is 21 gauge, tube wall thickness is 0.4 m
m, and distilled water was used as the test liquid.
なお、ここで点滴保持率について簡単に説明すると、上
記したようにクランプによる流量調節は経時的に変化し
く通常遅くなる）、この変化の少ないものほど良いとさ
れている。Here, a brief explanation of the drip retention rate will be given.As mentioned above, the flow rate adjustment by the clamp changes over time and usually becomes slower), and it is said that the smaller this change is, the better.
この変化を表わすものとして点滴保持率という用語が使
用されており、具体的には単位時間における点滴筒内の
薬液の滴下スピードの保持率で表わしている。The term drip retention rate is used to express this change, and specifically, it is expressed as the retention rate of the dripping speed of the drug solution in the drip tube per unit time.
通常下式のごとく点滴開始時と１２０分経過時の滴下数
で計算される。It is usually calculated by the number of drops at the start of infusion and after 120 minutes, as shown in the formula below.
上表にみられるように、点滴保持率がその許容限界であ
る７５％以上確保するためにはチューブ内径が１．５ｍ
ｍ以下であることが必要であり、８５％以上の点滴保持
率を確保するにはチューブ内径を１．２闘以下とすれば
よいことがわかる。As shown in the table above, in order to ensure the drip retention rate is at least 75%, which is the allowable limit, the tube inner diameter must be 1.5 m.
It can be seen that the inner diameter of the tube should be 1.2 m or less in order to ensure an infusion retention rate of 85% or more.
またクランプをフリーにした状態での１分間に落ちる滴
数をみると、必要滴数である６０滴以上はチューブ内径
が０．７ ｍｗ以上必要である。Also, looking at the number of drops falling per minute with the clamp free, the required number of drops of 60 or more requires a tube inner diameter of 0.7 mw or more.
しかし下表に示すように血液等の高粘度液で６０滴以上
保持するためにはチューブ内径を１．０ ｍｍ以上とす
ることが必要である。However, as shown in the table below, in order to hold 60 or more drops of a highly viscous liquid such as blood, the inner diameter of the tube must be 1.0 mm or more.
なお、下表の試験ではＰＶＰ（ポリビニルピトリドン）
・ソルビット混合液の疑似血液を使用し、１分間に落ち
る滴数について調べてみた。In addition, in the tests in the table below, PVP (polyvinyl pyridone)
- Using a simulated blood mixture of sorbitol, we investigated the number of drops that fall per minute.
以上が本発明においてチューブ内径を０．７〜１．５關
好ましくは１．０〜１．２關に限定した理由であるが、
本発明ではこうした内径を有する可撓性プラスチックチ
ューブを点滴筒３の下方に接続せしめるものである。The above is the reason why the inner diameter of the tube is limited to 0.7 to 1.5, preferably 1.0 to 1.2, in the present invention.
In the present invention, a flexible plastic tube having such an inner diameter is connected to the lower part of the drip tube 3.
即ち点滴筒３の上方に接続されるチューブ２ば、針１を
通して流出する薬液・血液等を単に点滴筒３に導（ため
のものであり、その径は点滴保持率等に直接影響しない
ためである。In other words, the tube 2 connected above the drip tube 3 is simply used to guide the medicinal solution, blood, etc. flowing out through the needle 1 to the drip tube 3, and its diameter does not directly affect the drip retention rate. be.
なお、本発明が適用される輸液輸血セットは図示したも
のに特定されないことは言うまでもない。It goes without saying that the infusion blood transfusion set to which the present invention is applied is not limited to what is shown in the drawings.
以上説明した本発明によれば、点滴筒の下方に接続され

トに何らかの衝撃が加わっても、注射液５に伝わる振動

ど、種々のすぐれた効果が得られるものである。According to the present invention described above, the inner diameter of the flexible plastic tube connected below the drip tube is 0.7 to 1.5.
By setting it preferably between 1.0 and 1.2, it is possible to improve the drip retention rate with a special lamp with grooves, etc., ensure a stable drip flow rate, and reduce the tube diameter. Therefore, even if some kind of shock is applied to the transfusion set during use, the vibration transmitted to the injection solution 5 is reduced, and therefore, various excellent effects can be obtained, such as eliminating the need for the conventional rubber tube 7. .
なお、本発明は特殊クランプとの併用を否定するもので
はなく、特殊クランプと本発明の組合せにより、さらに
すぐれた効果が得られることは言うまでもない。It should be noted that the present invention does not preclude its use in combination with a special clamp, and it goes without saying that even better effects can be obtained by combining the special clamp and the present invention.
