Description

  The present invention relates to an apparatus for transferring a volatile liquid, such as an anesthetic, from a container to a receiver provided in an inhaler.

  General anesthesia is administered as an inhalation gas or infusion liquid. Inhalation anesthesia consists of various medical gases and anesthetics, which are mixed in appropriate proportions and then administered to a patient to produce general anesthesia. In order to maintain the effect of anesthesia for the required duration (usually the duration of the operation), the anesthesia cycle must be maintained. An inhalation anesthetic is a volatile substance having a relatively low boiling point and a relatively high vapor pressure, and is stored in a bottle in a liquid state. Commonly used inhalation anesthetics are nitrous oxide (known as laughing gas), sevoflurane, desflurane, isoflurane, enflurane and halothane. The anesthetic is administered to the patient through an anesthesia inhaler attached to the anesthetic device.

  Accidental inhalation of vaporized gas by health care workers can cause drowsiness, and if this inhalation is repeated over a period of time, it causes health problems and is harmful. When an anesthetic-stored bottle is connected to the inhaler and removed from the inhaler, at any time leakage of volatile substances into the atmosphere must be completely prevented or kept to a minimum . Devices are known in the prior art to minimize leakage of anesthetic into the atmosphere. These conventional devices are designed so that volatile anesthetics are exposed to as little air as possible during connection and removal of the supply container. Also, the inhaler attached to the anesthesia device is intended to be used with a specific anesthetic agent, and is required to prevent accidental container mix-up during the setup phase. In the prior art, anesthetic containers and plugs have a special shape or protrusion, and the connection adapter has a complementary shape or recess for engaging the plug of the container. However, the conventional apparatus is not fail-safe (no double safety mechanism) and has a problem that it is easily broken by continuous use, careless storage and careless handling. Furthermore, the conventional apparatus has a problem that a certain amount of liquid remaining in the flow path of the assembly connecting the receiver to the container leaks into the atmosphere after the liquid transfer operation is completed.

  U.S. Pat. No. 5,381,836 describes a device for administering a volatile liquid medicament applied to a patient by means of an anesthesia inhaler, comprising a supply container and an inhaler with a reservoir. ing. Both the supply container and the inhaler include a valve assembly that shuts off the flow of liquid from the supply container to the reservoir when closed. The supply container and reservoir are connected to each other by a bayonet connection formed when the index elements on the container correspond. The valve assembly in the container is opened when the two containers are connected to each other by means of an insertion member arranged in the suction pipe. The suction pipe is pivotable between a raised position and a lowered position so that the valve can be opened and the storage of liquid into and from the reservoir can be controlled. It has become.

  In the device described in this document, the opening and closing of the valve assembly located in the supply container and the inhaler does not control the flow of volatile liquid from the container to the inhaler reservoir. The suction pipe rotates from the lowered position to the raised position, thereby opening the valve (provided between the suction pipe and the receiver reservoir) and controlling the liquid flow. In this configuration, there is absolutely no means for preventing liquid trapped between the valve assembly and the inhaler disposed in the supply container from leaking into the atmosphere while the supply container is removed from the receptacle. Not.

  US Pat. No. 5,505,236 describes a system for supplying a liquid anesthetic to an anesthesia inhaler. The system has a supply container with an outlet that forms a spout, through which anesthetic can be discharged. A receiver is disposed in the inhaler for storing anesthetics, and a receiver station is provided in the inhaler for receiving a container spout. The anesthetic flows from the container through the spout into the receiver by the action of gravity. A container spout is located at the station to define the maximum level of liquid anesthetic in the inhaler when gas flow into the container is hindered by an increase in liquid anesthetic level. Is done. In one embodiment, a fragile seal is provided in the container, an outlet valve is provided in the container, and an inlet valve is provided in the receiver station. These valves open automatically when the container is inserted into the receiver station of the inhaler. Also preferably, the spout of the container is movable with respect to the sputum so as to automatically break the fragile membrane when the container is inserted into the receiver station of the inhaler.

  The system operates with a spring controlled outlet valve in the container and an inlet valve in the receiver station. The container also has a movable spout that automatically opens the valve when the container is inserted into the receiving station of the inhaler. The sequence of operations for opening the receiver station valve is accomplished by first applying a smaller compressive force to the receiver station valve spring than the container valve. The one described in this document is not a fail-safe system and can cause leaks in continuous use of the device.

  US Pat. No. 5,687,777 discloses an anesthesia inhaler filling valve that can be used in connection with an anesthetic bottle with a standard key system with a rotating spear with ears, available on the market. Are listed. Such an anesthetic bottle is inserted into the inhaler filling valve in a locked state. The inhaler filling valve has an internal valve that is opened to introduce liquid anesthetic into the inhaler reservoir. With the slot of the inhaler filling valve corresponding to the mating ear of a standard anesthetic bottle, only the appropriate anesthetic bottle engages and is screwed into the filling valve designed for that particular anesthetic. It has become possible to be.

  The device described in this document is suitable for preventing accidental confusion of the anesthetic agent container, in which an anesthetic agent container with an incompatible anesthetic agent is fitted into the inhaler at the stage of setup. The valve opening / closing sequence is not described in this document.

  US Pat. No. 6,585,016 describes a system that facilitates the transfer of a liquid anesthetic from an anesthetic bottle to an anesthetic inhaler. The system includes a bottle receiver subassembly, an anesthetic agent bottle, and a filling device disposed on the anesthetic inhaler. The bottle receiver subassembly and the filling device each have a locked configuration so that only the correct anesthetic is filled into the anesthesia inhaler. The bottle receiver subassembly has a receiver subassembly valve assembly that engages a filling valve assembly disposed within the filling device. The size and configuration of the receiver subassembly valve assembly and filling valve assembly ensures that the anesthetic is delivered to the anesthetic inhaler only when the anesthetic is safely flowing from the anesthetic bottle to the anesthetic inhaler. Designed to do.

  The device described in this document is suitable for preventing accidental confusion of the anesthetic agent container, in which an anesthetic agent container with an incompatible anesthetic agent is fitted into the inhaler at the stage of setup. The valve opening / closing sequence is not described in this document.

  What is needed is an improved connection device that minimizes leakage of volatile liquids or vapors and ensures that the correct anesthetic container is connected to the inhaler inlet, regardless of operator skill. Yes.

  Throughout this specification, the terms “valve”, “seal element” and “plug element” are used interchangeably to denote the same component.

  In conventional devices, when anesthetic is transferred from the container to the receiver of the inhalation unit, a trace amount of anesthetic liquid remains trapped in the liquid path between the valve of the receiver and the valve of the container. The trapped liquid / fluid escapes into the atmosphere when the container is removed. Inhalation by humans who are not intended to inhale it poses an unavoidable occupational risk to all humans working in the area where such anesthetic transfers are made.

  That is, in an improved transfer device for volatile liquids containing anesthetic fluid, the opening of the connection between the transfer device and the inhaler in the liquid transfer sequence when the valve is opened and closed continuously The valve that guards the container is opened first, and then the valve that guards the opening of the connection between the transfer device and the anesthetic agent container is opened, thereby connecting the flow path from the container to the inhaler. A predetermined amount of liquid is transferred from the container to the inhaler, and after the transfer is complete, the valve that guards the opening connecting the container to the transfer device is first closed, and then the transfer device is connected to the inhaler It is reasoned that the valve guarding the opening is closed so that the flow path between the container and the inhaler is blocked and there is no opportunity for residual liquid to transfer and leak out of the container. It is considered to be specific. In the present specification, the realization of this valve opening / closing sequence, which is referred to as “the most preferable valve operation sequence”, is a minimum object that brings out the common technical features of the present invention. It is intended to provide various measures to achieve.

  The present invention provides a connection device for connecting a container having a volatile anesthetic to an inhaler unit attached to the anesthetic administration device. The connection device includes a first receiver subassembly connected to a container having a volatile anesthetic and a second receiver subassembly connected to an inhaler. The first and second receiver subassemblies comprise internal components that receive a biasing force from the spring element and close the flow path when the connecting device is inactive.

  According to the present invention, the flow path closing device is activated by a two-stage movement of the first receiver subassembly attached to the container relative to the second receiver subassembly. The first stage movement opens the valve assembly located in the second receiver subassembly, the second receiver subassembly is connected to the inhaler, and then the second stage movement causes the first receiver to move to the first receiver subassembly. The valve assembly arranged in the subassembly is opened and the liquid passes through the connecting device. When the container is removed from the inhaler, the series of operations described above is reversed, and this removal is performed in two stages. In the first stage, the valve assembly connecting the first receiver subassembly to the container is closed, In the second stage, the valve assembly connecting the second receiver subassembly 0 to the inhaler is closed. This is particularly effective in preventing volatile anesthetics from escaping into the atmosphere. This continuous opening and closing operation of the valve assembly allows the volatile anesthetic agent to enter the atmosphere while the filled container is connected to the inhaler and then removed from the inhaler and the liquid flow path of the transfer container is blocked. It is prevented from escaping.

  The device according to the invention also includes a container-identifying slot on the mating surface that mates with a protrusion provided on the receiver subassembly body to ensure the use of a specific anesthetic. This prevents accidental use of an anesthetic agent that is different from the one for which the assembly was designed.

  The apparatus according to the present invention (see FIGS. 1 to 12) includes a first receiver subassembly 50 and a second receiver subassembly 30.

  The second receiver subassembly 30 includes a spring 3, an internal pin 5, a gasket 9, a stop bush 11, and a safety cap 13 disposed in the second receiver subassembly main body 1. In the operative arrangement, each component of the second receiver subassembly 30 is disposed in the second receiver subassembly 1 by screw engagement between the second receiver subassembly body 1 and the stop bush 11. The A liquid flow path (not specifically numbered) is formed in the second receiver subassembly 30 so that the liquid passes through the second receiver subassembly 30. In the operative arrangement, the inner pin 5 and the gasket 9 are held in a valve seat disposed on the second receiver subassembly in a biased state, whereby liquid is contained in the second receiver subassembly 30. Is prevented from passing through. The safety cap 13 removably fitted in the bushing 11 prevents the closing element of the second receiver subassembly from being accidentally opened when not in use, and the components of the second receiver subassembly 30 are Protect. The second receiver subassembly 30 is fitted into the inlet of an inhaler (not shown in particular).

  The first receiver subassembly 50 includes a first receiver subassembly main body 19 having an internal flow path. The internal pin 17 and the gasket seal 15 are fitted into one open end of the first receiver subassembly body 19, and the spring support member 23 and the gasket 25 are assembled at the other open end of the first receiver subassembly body 19. It has been. In the operating arrangement, the internal pin 17 and the gasket seal 15 are held by the spring support member 23 in a state of being biased by the spring 21, thereby preventing liquid from passing through the first receiver subassembly 50. . A safety cap 27 detachably fitted into the first receiver subassembly body 19 protects each component of the first receiver subassembly 50. The first receiver subassembly 50 is fitted into the volatile liquid container 29.

  The “most preferable valve operation sequence” is realized as follows. A common feature of all illustrated embodiments is a method for transferring volatile liquid from a container to a receiver, comprising: (a) providing a first receiver subassembly coupled to the container; b) providing a second receiver subassembly coupled to the receiver; and (c) selectively engaging the first and second receiver assemblies with a pair of components.
