Description

  The present invention relates to an infusion tube, a drug solution administration set, and a connection adapter used mainly in medical practice.

  In medical practice, except for oral drugs and transdermal drugs, as means for administering a drug solution into a patient's body, administration means by injection or infusion are common.

  In administration of medicinal solution by injection, before administration, it is necessary to open a bottle such as an ampoule, suck out the medicinal solution from the bottle with a syringe, and then discharge the air outside the syringe so that no air remains in the syringe It becomes.

  Also, for powdered drugs, inject saline into a bottle such as an ampule to dissolve the drug, and then suck out the drug solution from the bottle with a syringe, so that no air remains in the syringe. The operation | work which discharges | emits air out of a syringe is needed.

  On the other hand, when a large amount of drug solution is administered or when administration is performed over a long period of time, administration means by drip is usually used. However, in the administration by drip, before administration, one end of an infusion bag containing a drug solution is used. It is necessary to perform a fluid passing and defoaming operation in which a chemical solution is passed so that air does not enter the infusion tube after connecting through a coupling means such as a hollow needle provided at the tip of the infusion tube.

  Such preparations for syringes and infusion sets are routine tasks for doctors and nurses and are relatively time consuming, and in hospitals where many patients who require medicinal solution administration are hospitalized, all patients who need administration Preparing a syringe and infusion set for the minute is a very tedious task, not to mention the labor of a medical staff, and can be injured by accidentally touching a hollow needle, etc. Careful handling is required because there is a risk of contamination with bacteria.

  In particular, in ambulances, emergency hospitals, and disasters, patients often need to be administered by injection or infusion as soon as possible, but the above-mentioned preparatory work hinders rapid administration. Therefore, development of a drug solution administration means that can be easily and quickly prepared is strongly desired.

  In order to solve this problem, an infusion set has been developed that simplifies the mounting of an infusion set, and realizes a significant rationalization of work and high sterility at the same time (for example, Patent Document 1).

JP-A-8-52211

  That is, the drip set described in Patent Document 1 has an infusion tube connected upstream and downstream of the drip chamber, a bottle needle is connected to the tip of the upstream infusion tube, and a connection pipe is provided in the middle. A solution-filled bag is attached so that it can communicate via a connecting tube, a connector or a puncture needle is attached to the tip of the infusion tube on the downstream side of the drip chamber, and a flow rate adjusting clamp is attached halfway, The drip chamber and the infusion tube on the downstream side are filled with the solution. By pre-sealing the solution in the infusion tube on the downstream side of the drip chamber, the operation of passing the solution through the infusion tube is eliminated. Thus, it can be said that the preparation of the infusion set has been simplified.

  However, in the invention described in Patent Document 1, the infusion tube on the upstream side of the drip chamber needs to pass the solution from the bag containing the solution, and the infusion tube is provided at one end of the infusion bag containing the chemical solution. There is no difference from the conventional infusion set in that it is necessary to stab the bottle needle provided at the tip of the bottle. Therefore, you may be injured by touching the bottle needle accidentally, and bacteria may adhere to the bottle needle. There is a risk of letting it go.

  In addition, there is a problem that the air existing in the drip chamber may enter the infusion tube on the downstream side of the drip chamber during storage and the like, which eventually requires a liquid passing operation to remove the entered air. .

  Therefore, as a result of the inventor's extensive studies to solve the above problems, the present invention is an infusion tube connected to one end of a medicine-enclosed bag, and the air is not present in the infusion tube. The infusion tube of the invention has been developed.

  At the same time, the present inventor has developed the medicinal solution administration set of the present invention comprising such an infusion tube and a drug-filled bag.

  That is, the present inventor, for the infusion tube connected to one end of the medicine enclosing bag, in the manufacturing stage, liquid such as physiological saline or medicinal solution is enclosed in advance in the infusion tube, or the infusion tube is evacuated or vacuumed. If air is not allowed to exist in the infusion tube by making it collapsed, preparation work such as infusion and defoaming into the infusion tube in hospitals and ambulances can be simplified. As a result, it has been found that preparation of a drug solution administration set can be realized extremely rapidly as compared with a syringe and an infusion set.

  In addition, as a medicinal solution administration set, the infusion tube is already connected to one end of the drug-enclosed bag in the manufacturing stage, so that the work of attaching the infusion tube to the drug-enclosed bag in a hospital or an ambulance is omitted. They learned that they could solve the problem of injuries or attachment of germs by accidentally touching bottle needles.

  The present invention has been completed on the basis of the above findings, and provides an infusion tube and a medicinal solution administration set that realize a quick preparation of a medicinal solution administration set represented by infusion and injection, and that have improved hygiene and safety. Furthermore, it aims at providing the connection adapter which can be used conveniently in the connection of the chemical | medical agent enclosure bag, infusion tube, etc. in this infusion tube and a chemical | medical solution administration set.

  In order to achieve this object, an infusion tube according to the present invention is an infusion tube connected to one end of a medicine-filled bag, and is characterized in that no air exists in the infusion tube.

The medicinal solution administration set according to the present invention comprises such an infusion tube and a drug-filled bag.
Hereinafter, the infusion tube and the medicinal solution administration set of the present invention will be described in detail.

  The infusion tube of the present invention is connected to one end of a drug-filled bag such as an infusion bag or a medicine bottle. This infusion tube is subjected to external pressure or impact that normally occurs during storage or use. Is not particularly limited as long as it has hermeticity and physical strength such that the encapsulated liquid does not leak, and specifically, for example, generally known polymer materials such as , Polyurethane, polyethylene, ethylene-vinyl acetate copolymer, polyvinyl chloride, polybutadiene, polypropylene, cellophane, polychloroprene, polyamino acid, nitrile rubber, butyl rubber, silicon rubber, etc., which are formed into a tube shape are used. It is also possible to laminate or mix at least one selected from these polymer materials. The may be used to form the tubular those.

  Further, the infusion tube of the present invention is not limited to a simple straight tube. For example, a three-way stopcock is provided in the middle of the infusion tube, and a bifurcating branch is provided, or a later-described administration state visualizing means is provided in the route. Is also included.

  On the other hand, the medicinal solution administration set of the present invention is for administering an arbitrary liquid into a patient's body, and is composed of a combination of the infusion tube and the medicine-enclosed bag.

  The medicine-enclosed bag has a hermeticity and physical strength enough to prevent tearing or leakage of the encapsulated liquid even if it is subjected to external pressure or impact that normally occurs during storage or use. It is not particularly limited, and known drip bags and medicine bottles can be used. Generally, known polymer materials such as polyurethane, polyethylene, ethylene-vinyl acetate copolymer, polyvinyl chloride are used. It is preferable to use a polybutadiene, polypropylene, cellophane, polychloroprene, polyamino acid, nitrile rubber, butyl rubber, silicon rubber and the like suitably formed into a bag shape, and at least selected from these polymer materials You may form and use what laminated | stacked or mixed 1 or more types in the bag shape.

  And in the infusion tube and chemical | medical solution administration set in this invention, it has the biggest characteristic in the point which made air not exist in the said infusion tube.

  That is, if the liquid is filled in the infusion tube in advance in the manufacturing stage so that the infusion tube is filled with the liquid and air is not present in the infusion tube, the infusion tube is connected to the drug-encapsulating bag. Thus, the liquid passing and defoaming work can be completed. Thus, when using in a hospital, an ambulance or the like, it is possible to quickly prepare a chemical solution administration set.

  In addition, if the infusion tube is evacuated or collapsed in the manufacturing stage so that air does not exist in the infusion tube, the liquid in the medicine enclosure bag can be simply connected to the infusion bag. Is drawn into the infusion tube, or after connection, the infusion tube is filled with liquid just by lightly applying pressure to the medicine-filled bag. In the case of use in the above, it is possible to realize quick preparation of a drug solution administration set.

  Here, the means for connecting the drug-enclosed bag and the infusion tube is not particularly limited, but specifically, for example, a seal plug means such as silicone rubber is provided at one end of the drug-enclosed bag and / or the infusion tube, In use, a hollow needle or the like is passed through the sealing means and connected, or a connecting member consisting of a male type and a female type is provided in the drug-filled bag and the infusion tube, respectively, and the connecting member is connected in use. Examples of the connecting means are as follows.

  The connecting means is preferably provided with a cap or the like so as not to be contaminated by various germs, etc. Further, liquid stored in an infusion tube or a medicine-filled bag during storage or the like leaks from the connecting means or air Partitioning means such as an easy peel seal is provided at the end of the infusion tube or drug-filled bag where the connecting means is provided or in the vicinity thereof so as to prevent invasion of bacteria and other germs. It is preferable that the partition means such as a seal is peeled off.

  Here, when the liquid is sealed in the infusion tube, the liquid to be sealed is not particularly limited as long as it is a chemical liquid that is generally used in medical practice, and specifically, for example, physiological saline, glucose aqueous solution, etc. Liquids that do not have a serious effect even when administered to the human body, pain relievers, nutrients, antibiotics, and other chemicals that have a pharmacological effect on the human body.

  In addition, the liquid enclosed in the drug-filled bag and the infusion tube may be different from each other. For example, the drug-filled bag may contain pain relief, nutrients, antibiotics, other chemicals that have a pharmacological effect on the human body, etc. On the other hand, the infusion tube may contain a liquid that does not have a serious influence even when administered to the human body, such as physiological saline or an aqueous glucose solution.

  Furthermore, the liquid medicine is not limited to the liquid liquid literally, and the inside of the medicine-filled bag is partitioned by a partitioning means such as an easy peel, and during storage, the powdered medicine and the liquid are separated in the inside of the liquid medicine bag. The powdery medicine and the liquid may be mixed by peeling the easy peel seal in use.

  In addition, it is not always necessary to enclose the drug solution in the drug-enclosed bag in advance. In use, a desired drug solution may be injected into the drug-enclosed bag using a syringe or the like.

  By the way, in the medicinal solution administration set of the present invention, since the drug-filled bag and the infusion tube exist separately, they may be injured by accidentally touching the hollow needle at the time of connection, or the connecting means There is a problem of adhering various bacteria.

  In this regard, in the present invention, in the manufacturing stage, it is preferable to configure a medical solution administration set in which an infusion tube is connected in advance to one end of a medicine-enclosed bag. By configuring in this way, the inside of a hospital or ambulance When using the product, it is possible to omit the work of connecting the drug-filled bag and the infusion tube, improve safety and hygiene, and realize more rapid preparation of the drug solution administration set. Can do it.

  Here, the means for connecting the infusion tube to one end of the medicine enclosure bag is not particularly limited, and specifically, for example, after the medicine enclosure bag and the infusion tube are separately manufactured, Examples include means for connecting the infusion tube to the infusion tube using the connecting means and the like, but there is a risk that liquid may leak from the connection site or the like, or air or bacteria may enter during storage.

  Therefore, in the present invention, the medicine-enclosed bag provided with the connection means so that the liquid enclosed in the medicine-enclosed bag or the infusion tube does not leak from the connection means or air or germs enter during storage or the like. It is preferable that partition means such as an easy peel seal is provided at the end of the tube or the end of the infusion tube or in the vicinity thereof, and pressure is applied during use to peel off the partition means such as the easy peel seal.

  In this respect, that is, in order to prevent such liquid leakage and contamination, it is preferable in the present invention to integrally form the drug-filled bag and the infusion tube at the manufacturing stage.

  Here, the method for integrally forming the drug-enclosed bag and the infusion tube is not particularly limited, but specifically, for example, two films or sheets made of a polymer material are superimposed, Examples include a means for providing a mold for a medicine-enclosed bag and an infusion tube by means such as heat sealing, and cutting off the outer edge of the mold simultaneously with heat sealing or after heat sealing or during use.

  In this case, since the medicine-enclosed bag and the infusion tube are integrally formed, the infusion tube is more suitable than a vacuum in the infusion tube or the liquid in the infusion tube and the liquid in the medicine-enclosed bag are different. It is preferable to enclose the same liquid (chemical solution) enclosed in the medicine enclosure bag.

In addition, the liquid (medicine solution) is sealed in the drug enclosure bag and the infusion tube. First, a film or sheet made of two polymer materials is formed into a bag shape, and after the liquid is injected into this bag, heat sealing, etc. The method of sealing the liquid at the same time as applying the mold of the medicine enclosing bag and the infusion tube by the above means, or the film or sheet made of two polymer materials were overlapped, and then a part was opened as the liquid inlet The method of injecting the liquid from the liquid injection port after applying the mold of the drug-filled bag and the infusion tube by means such as heat sealing in the state, and finally sealing the liquid injection port by means of heat sealing, etc. Can do.

  The medicinal solution administration set of the present invention has an insertion tube attached to the end of the infusion tube on the side not connected to the drug enclosure bag, and the insertion needle is inserted into the human body etc. An encapsulated liquid (medical solution) is administered to a human body or the like.

  Here, the method for sending the liquid (medicine solution) enclosed in the drug-enclosed bag to the human body is not particularly limited, but in general, the pressure is obtained by grasping or pushing the drug-enclosed bag. To push the liquid in the medicine-filled bag and send it to the human body, or to send the liquid in the medicine-filled bag to the human body little by little, as in the case of administration by infusion And so on.

  The means for connecting the insertion needle to the end of the infusion tube is not particularly limited, but specifically, for example, the end of the insertion needle is screwed into the end of the infusion tube, or the infusion tube And / or a sealing means such as silicon rubber is provided at one end of the insertion needle, and in use, a hollow needle or the like is passed through the sealing means and connected, or a connecting member composed of a male type and a female type is connected to the infusion tube. Examples of the connecting means include a connecting unit that is provided on each of the insertion needles and connects the connecting member during use.

  The connecting means is preferably provided with a cap so as not to be contaminated by germs and the like, and further, the liquid sealed in the infusion tube during storage or the like does not leak from the connecting means or enter the germs. In this way, partition means such as an easy peel seal is provided at the end of the infusion tube where the connection means is provided or in the vicinity thereof, and the partition means such as the easy peel seal is peeled off by applying pressure during use. It is preferable.

  By the way, recently, as a means for visually confirming whether a drug solution or the like enclosed in an infusion bag is reliably administered to a patient through an infusion tube, a drip chamber (infusion tube) is provided in the route of the infusion tube. It is common to provide a means for visually confirming the administration state.

  Therefore, when the medicinal solution administration set of the present invention is used as an infusion set, the puncture needle is not directly attached to the end of the infusion tube that is not connected to the drug-enclosed bag, but at the end. It is preferable to use it by attaching an administration state visualizing means such as a drip chamber and attaching an insertion needle to the end of a tube (another infusion tube) communicating with the downstream side of the administration state visualizing means.

  However, with such a configuration, an operation for passing the liquid through the administration state visualizing means and the downstream tube below the administration state visualizing means is required.

  In this regard, in the present invention, a tube is communicated with one end of the administration state visualizing means, and the administration state visualizing means and a tube filled with a liquid are combined with the above-mentioned medical solution administration set to provide a chemical administration set. It is preferable to configure, and by using such a configuration, it is possible to omit the operation of passing the liquid through the tube on the downstream side below the administration state visualizing means in use, and the administration state visualizing means is used. In this case, it is possible to quickly prepare the chemical solution administration set.

  In the present invention, it is also preferable to provide the administration state visualizing means in the route of the infusion tube that is previously connected / communicated to the medicine enclosing bag in the manufacturing stage, and this configuration also provides the administration state visualizing means during use. The operation of passing the liquid through the tube on the downstream side described below can be omitted, and the quick preparation of the drug solution administration set using the administration state visualizing means can be realized.

  In addition, a drip chamber is representative as a currently used administration state visualizing means, but in the present invention, there is no particular limitation as long as the liquid passage state can be visually recognized. In addition to the drip chamber, other administration state visualizing means, for example, a rotating body that rotates in accordance with the state of liquid passing through the infusion tube can be used.

  Here, the means for providing the administration state visualizing means in the route of the infusion tube is not particularly limited, and specifically, for example, after the administration state visualizing means and the two infusion tubes are individually manufactured, The connection state visualizing means and the infusion tube are connected via a hollow needle, or a connection means comprising a male type and a female type connecting member on the administration state visualizing means and the infusion tube, respectively, for connecting the connection member, etc. However, there is a risk that liquid may leak from the connection site or germs may enter during storage or use.

  In view of this point, in the present invention, in order to prevent the leakage of liquid and the mixing of germs and to realize the quick preparation of a drug solution administration set, a drip chamber is provided as a dosing state visualizing means in the manufacturing stage. It is preferable that the drip chamber and the infusion tube are integrally formed.

  Here, the method of integrally forming the drip chamber and the infusion tube is not particularly limited, but specifically, for example, two films or sheets made of a polymer material are stacked, and then the drip chamber is formed. And a means for cutting off the outer edge of the mold at the same time as heat sealing or after heat sealing or during use.

  In this case, the liquid is sealed in the drip chamber and the infusion tube by first forming a film or sheet made of two polymer materials into a bag shape, injecting the liquid into the bag, and then performing heat sealing or the like. A method of enclosing a liquid at the same time as applying a mold of a drip chamber and an infusion tube by means, or overlapping a film or sheet made of two polymer materials, and then opening a part as a liquid inlet Examples include a method of injecting a liquid from the liquid inlet after the drip chamber and infusion tube molds are provided by means such as heat sealing, and finally sealing the liquid inlet by means of heat sealing. .

  By the way, the visual confirmation of the administration state in the drip chamber as the administration state visualizing means is performed by allowing a certain amount of air to exist in the drip chamber and dropping the liquid in the drip chamber.

  Therefore, also in the chemical solution administration set of the present invention, when the drip chamber is used as the administration state visualizing means, it is necessary to allow air to exist in the drip chamber during use.

  Therefore, when a drip chamber is used in the drug solution administration set of the present invention, it is preferable that a liquid exists in the drip chamber and the infusion tube and a certain amount of air is interposed in the drip chamber in advance.

  However, if the air intervened in the drip chamber enters the infusion tube during storage or the like, it is necessary to remove the air in the infusion tube at the time of use. .

  In this regard, in the present invention, it is preferable to provide a partition with an easy peel seal between the drip chamber and the infusion tube, or between the drip chamber and the tube, that is, the air interposed in the drip chamber is the infusion solution. It is preferable that the infusion tube and the drip chamber are partitioned by the easy peel seal so as not to enter the tube, and pressure is applied during use to peel off the easy peel seal.

  On the other hand, in the present invention, in addition to the means for providing the partition by the easy peel seal, it is also preferable to provide an air injecting means capable of feeding a certain amount of air into the drip chamber.

  The air injecting means is not particularly limited as long as a certain amount of air can be fed into the drip chamber during use. Specifically, for example, a rubber stopper is provided in a part of the drip chamber. A means for injecting air by inserting a needle such as a syringe into the rubber stopper, or providing an air bag communicating with the drip chamber, and providing an easy peel seal between the air bag and the drip chamber. A means for sending air in the air bag into the drip chamber by applying pressure to break (peel) the easy peel seal can be mentioned.

  In particular, in the present invention, the air bag is preferably formed integrally with the drip chamber. For example, a mold of a drip chamber and an air bag is provided by heat sealing, and the air bag is simultaneously or after heat sealing. And an easy peel seal between the drip chamber and the drip chamber.

  By the way, it is often necessary to administer a drug different from the drug solution in the infusion bag, for example, an anticoagulant for blood such as painkillers or heparin, during or after administration of the drug solution by infusion.

  Correspondingly, in the present invention, by providing a chemical solution injection means in the infusion tube and / or the route of the tube, a drug different from the drug solution in the drug encapsulating bag is administered during or after the administration of the drug solution. It can also be configured to be able to.

  The chemical solution injecting means is not particularly limited as long as a desired chemical solution can be fed into the infusion tube at the time of use. Specifically, for example, a rubber plug or the like is connected to a part of the infusion tube. Means for injecting medicinal liquid by inserting a needle such as a syringe into the rubber stopper, means for injecting medicinal liquid by attaching another medicinal liquid administration set of the present invention to the connecting means, or medicinal liquid communicating with an infusion tube In addition to providing a bag, an easy peel seal is provided between the drug solution bag and the infusion tube, and pressure is applied during use to break (peel) the easy peel seal so that the drug solution in the drug solution bag is infused. A means for feeding into the tube can be mentioned.

  In particular, in the present invention, it is preferable to form the drug solution bag integrally with an infusion tube or a tube for drugs or the like frequently used at the same time. For example, the mold of the infusion tube or tube and the drug solution bag is formed by heat sealing. It can be formed by providing an easy peel seal between the drug solution bag and the infusion tube or tube at the same time as heat sealing or after heat sealing.

  As described above, the connection between the drug-filled bag and the infusion tube in the infusion tube and the medicinal solution administration set of the present invention, the connection between the infusion tube and the administration state visualizing means, the connection between the infusion tube and the insertion needle, or the tube and insertion The connection with the needle is achieved by connecting with a hollow needle or a connecting member, etc., but when connecting, liquid leaks from the medicine enclosure bag or infusion tube, or air enters. There is.

  Therefore, in the present invention, it is preferable to achieve these connections by using a coupling adapter in which a hollow needle having sharpened ends is passed through a slider that slides within a certain range in the outer casing.

  That is, for example, even if this connection adapter is attached to one end of the infusion tube, the slider is retracted so that the end of the infusion tube is not penetrated. When attached to one end of the bag, one end of the drug-enclosed bag and the end of the infusion tube are simultaneously penetrated by the hollow needle to complete the connection between the drug-enclosed bag and the infusion tube. If the adapter is used, it is possible to prevent the liquid from leaking from the medicine-filled bag or the infusion tube or the ingress of air during the connection work.

  The present invention is a very excellent infusion tube and medicinal solution administration set having the above-described configuration, realizing a quick preparation of a medicinal solution administration set, and improving hygiene and safety.

  That is, according to the present invention, in the infusion tube connected to one end of the medicine-enclosed bag, a liquid such as a physiological saline solution or a chemical solution is previously enclosed in the infusion tube in the manufacturing stage, or the inside of the infusion tube is evacuated or collapsed. It is configured so that air does not exist in the infusion tube by making it into a state, omitting the liquid passing through and defoaming work in the infusion tube in hospitals, ambulances, or disasters, etc. Prompt preparation can be realized.

  In addition, as a medicinal solution administration set, the infusion tube is already connected to one end of the drug-enclosed bag at the manufacturing stage, so that the work of attaching the infusion tube to the drug-enclosed bag in a hospital, an ambulance, or at the time of a disaster is omitted. Thus, it is possible to solve the problem of injuries or attachment of germs by accidentally touching the bottle needle or the like.

  That is, the infusion tube and the medicinal solution administration set of the present invention are novel medicinal solution administration means replacing normal injection or infusion, and are inexpensive, excellent in storage, hygiene, and usability, and also excellent in disposal. Moreover, it is suitable not only for normal medical use but also for stockpiling in preparation for earthquakes, fires and other great disasters, and its convenience is extremely great.

  Furthermore, the connection adapter according to the present invention includes a connection between the drug sealed bag and the infusion tube in the infusion tube and the medicinal solution administration set according to the present invention, a connection between the infusion tube and the administration state visualizing means, and a connection between the infusion tube and the insertion needle.
