Description

The present invention relates to a structure of a needle device housing that houses a needle device used in various medical therapies before or after use.

A needle device used in various medical therapies in a medical institution has a sharp structure at the tip thereof for the purpose of puncturing a treatment target. For this reason, the needle device is generally used in combination with a needle device housing (so-called needle cover) that can cover the tip of the needle device.
This needle device housing has a hollow, substantially cylindrical shape with a distal end closed and a proximal end opened. To combine the needle device and the needle device storage body, the tip of the needle device is inserted from the opening at the base end of the needle device storage body, and the entire needle device is stored in the hollow portion of the needle device storage body. Thereby, the sharp part of the tip of the needle device is covered with the needle device housing, and the finger operated by the medical staff does not come into contact with the tip of the needle device.
As a result, the finger operated at the tip of the needle device is not damaged, and blood or the like attached to the tip of the needle device does not adhere to the operated finger, so that a safe operation can be obtained.

As such a needle device housing for the purpose of preventing the puncture of the needle device, one that covers only the tip portion of the needle device is known. However, in such a needle device storage body, the proximal end portion of the needle device, the so-called needle base portion, is exposed from the proximal end portion of the needle device storage body, and a finger that operates the base end portion accidentally touches. There are things to do. For this reason, a needle device storage body that covers the entire needle device is known. For example, a needle cover body consisting of a needle cover body with an opening at one end and a closed end at the other end and a lid connected to the opening end by a hinge, and a linear groove for guiding the injection needle into the needle cover body inside the lid. A formed needle cover is disclosed (see Patent Document 1).
Such a needle cover accommodates the entire used needle device and does not expose any part of the needle device to the outside, so that it is useful for obtaining a puncture prevention effect. However, the main body and the lid of the needle cover are made of plastic. When the main body is covered with the lid, the space in the needle cover is blocked from the external space, and the air permeability between the two is lost. Thereby, water vapor | steam and various gas cannot be permeate | transmitted to the space inside a needle cover, and the needle apparatus accommodated in the needle cover cannot be sterilized. Therefore, the present needle cover is not suitable for the storage body of the needle device before use.
Also, a syringe needle package having a hollow tube shape that protects the needle of a puncture device having a needle at one end and a needle base at the other end, and the hollow tube has a length sufficient to cover the puncture device. A step that can fix the puncture device by contacting with the needle base of the puncture device, one end of the hollow tube is closed, the other end is open, and the opening has a flange; An injection needle package comprising at least a hollow tube and a shield, which aseptically seals the puncture device by adhering to each other, is disclosed (see Patent Document 2).
According to this injection needle package, the entire needle device is accommodated, and any part of the needle device is not exposed to the outside. In addition, the opening of the syringe needle package is configured to be equipped with a highly gas permeable shield, and the interior space of the syringe needle package can be sterilized and can be maintained in a sterile state. is there. For this reason, it is not only useful as a storage body after use of the needle device, but also applicable as a storage body before use of the needle device.

On the other hand, the needle devices used in various medical therapies include a metal needle device for puncturing the blood vessels and skin of the human body and a plastic device for mixing and preparing a specific drug in the infusion used for infusion therapy. A needle device and the like are known. When the metal needle device is used by puncturing the human body, it is usually used once and not used multiple times. In the case of preparing a drug, the plastic needle device may be prepared a plurality of times with a predetermined time, and may be used a plurality of times. In such a case, a plastic needle device for drug preparation is stored in a needle device housing after use and temporarily stored.

However, the proximal end portion of the injection needle package described in Patent Document 2 remains open when the shield is removed. For this reason, when the needle device described above is temporarily stored, it may be exposed to foreign matter or dust in the outside air.
Furthermore, the injection needle package described in Patent Document 2 houses the entire needle device, and does not expose any part of the needle device to the outside. For this reason, the base end part of the said injection needle package is comprised so that the base end part of a needle apparatus may not be protruded. That is, in the injection needle package, the needle base that is the proximal end portion of the needle device is disposed at a deep position in the hollow portion of the injection needle package.
For this reason, when the above-mentioned plastic needle device for drug preparation is temporarily stored and reconnected to a syringe or the like, it cannot be said that the visibility is high, and the operation may be somewhat complicated.

While comprising a stepped portion capable of supporting the needle device, and a base end hollow member having a hollow portion that is connected to the base end portion of the stepped portion and the base end is opened,
The base end hollow member is composed of an expandable and contractible tubular member that can be expanded and contracted in the axial direction, and the expandable and contractible tubular member contracts in the axial direction when a stress is applied in a direction from the base end toward the distal end. The proximal end of the member is movable to the distal side from the normal position, and is extended in the axial direction when the stress load is released, and the proximal end of the telescopic tubular member is moved from the moved position to the normal position. A needle device housing, characterized in that the needle device housing is movable.

According to the invention of (1), the telescopic tubular member of the proximal hollow member of the storage body main body of the needle device storage body can be contracted and extended in the axial direction.
That is, the open base end portion of the needle device housing can be moved back and forth in the axial direction.
Accordingly, when the needle device stored in the internal space of the needle device storage body is connected to a syringe or the like and used, the proximal end portion of the needle device storage body is moved to the distal end side, and the stored needle device Since the base end part which is a connection part can be exposed, visibility improves and connection operation becomes easy.
In addition, the operation of moving the proximal end of the needle device housing opening can be performed by applying a stress load that presses the distal end side with an operating finger, so that a safer and more reliable operation can be obtained. It is.

As a result, even if the proximal end portion of the stored needle device is exposed by the above-described operation, the proximal end portion can be covered again, and the storage operation can be performed more easily.
Furthermore, since the needle device is sufficiently covered when it is discarded as a used needle device after storage, a highly safe disposal operation can be performed more easily.
This is particularly useful in a needle device housing that houses the entire needle device from the needle body to the proximal end of the needle device and does not expose any part of the needle device to the outside.
In the case of the needle device storage body described above, the base end portion of the storage body main body that is open is configured so as to protrude from the base end portion end of the needle base.
As a result, the proximal end portion of the needle device is arranged at a deep position in the hollow portion of the housing body, and the connection operation is performed when the needle device is connected to the proximal end portion of the needle device with a syringe or the like. Was relatively cumbersome.
Therefore, in the case of the needle device storage body according to the present invention, the proximal end portion of the storage body main body can be contracted, the proximal end portion of the stored needle base can be exposed, And the connection operation can be performed safely and reliably.
Furthermore, it is very useful in the following aspects of the present invention.
A plastic needle device for drug preparation may be used multiple times.
In this case, the needle device once used for drug preparation may be temporarily stored until it is used for the next drug preparation. At this time, since the base end portion of the storage body main body is open, there is an undeniable possibility that the stored needle device is contaminated with foreign matter, dust, or the like. Therefore, it is possible to protect the needle device by attaching a cap that can be engaged with the proximal end portion of the needle device stored in the storage body main body portion, and closing the open state of the proximal end portion of the storage body main body portion. is there. At this time, in the case of the needle device storage body according to the present invention, the base end portion of the storage body main body can be contracted, and the base end portion of the stored needle base can be exposed. Thereby, there exists an effect which the attachment or detachment operation of the cap to a needle | hook apparatus becomes possible easily.

(2) The stretchable tubular member extends in the axial direction when stress is applied in the direction from the distal end toward the proximal end, and the proximal end of the telescopic tubular member can move from the normal position to the proximal side. Because
The needle device housing according to (1), wherein when the stress load is released, the proximal end portion of the telescopic tubular member is braked to a moved position.

According to invention of (2), the expansion-contraction tubular member of the base end hollow member of the storage body main-body part of a needle | hook apparatus storage body becomes extensible in an axial direction.
Furthermore, the extended telescopic tubular member can be held in the extended state.
Accordingly, even if the needle device is stored in the hollow portion of the storage body main body of the needle device storage body, the base end of the storage body main body further protrudes from the base end of the needle device.
For this reason, it is possible to securely store the needle device in the housing body without exposing the stored needle device to the external space, and the safety is high.

(3) The needle device housing according to (1) or (2) above, wherein the telescopic tubular member has a bellows structure.
According to the invention of (3), since the expansion / contraction mechanism of the needle device housing is achieved by the bellows structure, the operation for operating it is simple and the load stress during the operation can be reduced. Operability is obtained.
In addition, the configuration of the telescopic tubular member that makes it possible to achieve the telescopic mechanism of the needle device housing is simplified, which is advantageous from the viewpoint of manufacturing. Furthermore, it becomes possible to integrally mold the storage body main body of the needle device storage body, which is advantageous in consideration of manufacturing processes and costs.

(4) A needle body that can be punctured at the distal end, and a needle device that has a needle base portion at the proximal end and is provided with an engaging projection protruding outward on the outer peripheral surface of the distal end of the proximal end portion of the needle base portion; ,
It has a cylindrical shape with a long bottom in the axial direction, and a hollow part is formed with its distal end closed and its proximal end open, and the needle device can be stored in the hollow part, and the proximal end part extends and contracts in the axial direction. A storage body main body composed of a stretchable tubular member,
A needle device storage body comprising a substantially cylindrical cap having an inner peripheral surface with a lure that can be engaged with an engagement protrusion of the needle device,
Positional relationship such that when the engaging protrusion of the needle device and the lure of the cap are engaged, the proximal end portion of the container body opening is protruded from the proximal end portion of the cap. When the stress is applied in a direction from the base end to the tip, and the base end of the cap is open to the base of the housing body when the telescopic tubular member is contracted in the axial direction. A needle device housing, which is configured in a positional relationship so as to protrude from the end of the end.

According to the invention of (4), the needle device storage body is composed of three elements: a needle device, a storage body main body that stores the needle device, and a cap that can be engaged with the proximal end portion of the needle device. Yes.
Accordingly, the cap is engaged with the base end portion of the needle device after the needle device is stored in the storage body main body portion, so that the opening of the base end portion of the needle device can be covered. For this reason, it becomes possible to protect the hollow site | part of a needle | hook apparatus from contamination, such as a foreign material and dust. Moreover, it is also possible to substantially cover the opening of the base end portion of the storage body main body with the entire cap, and it is possible to protect against contamination of the hollow part of the storage body main body. As a result, it becomes possible to obtain high hygiene of the needle device housed in the needle device housing.
This aspect of the needle device housing is useful because the cap is removed immediately before use, so that the hygiene of the needle device is maintained until just before use. Also, when using a needle device that is used multiple times, such as a plastic needle device for drug preparation, store the needle device with high hygiene when temporarily storing it in the main body of the container. It is useful because it can.
Furthermore, according to this aspect, the expansion-contraction tubular member of the base end part of a storage body main-body part can be expanded-contracted. For this reason, each operativity at the time of attaching / detaching a cap with respect to the base end part of the needle | hook apparatus accommodated in the storage body main-body part mentioned above improves.

The needle device housing of this aspect has a configuration in which the telescopic tubular member at the base end of the housing main body can be expanded and contracted in the axial direction, and therefore the telescopic tubular member at the base end of the housing main body contracts. Thus, it is possible to move the proximal end portion opening of the storage body main body portion from the normal position to the distal end side.
As a result, stress is applied to the storage body main body by operating fingers to move the proximal end of the storage body main body opening from the normal position to the distal end side, and the base end of the stored cap is operated. It can be exposed to the extent that it can be gripped with a finger.
As a result, it is possible to easily attach / detach the cap.
In addition, since the telescopic tubular member at the base end portion of the storage body main body is configured to be able to expand and contract in the axial direction,
For example, when connected to a syringe or the like at the proximal end portion of the stored needle device, the connected portion is easily visually recognized, and the operability is improved.
Furthermore, since the cap covers the opening at the proximal end of the needle device and the opening at the proximal end of the storage main body, it is useful for disposal after use of the needle device.
That is, a liquid (medicine, blood, etc.) that covers each opening with a cap and adheres to the needle device housing body containing the needle device may leak to the outside through each opening. Absent.
For this reason, the disposal operation of the needle device housing with higher safety becomes possible.

Furthermore, the extended telescopic tubular member can be held in the extended state. Accordingly, even if the needle device is stored in the hollow portion of the storage body main body of the needle device storage body, the base end of the storage body main body further protrudes from the base end of the needle device.
For this reason, it is possible to reliably store the needle device in the storage body main body without exposing the stored needle device to the external space, and the safety is high.

(6) The needle device housing according to (4) or (5) above, wherein the telescopic tubular member has a bellows structure.

Operability is obtained. In addition, the configuration of the telescopic tubular member that makes it possible to achieve the telescopic mechanism of the needle device housing is simplified, which is advantageous from the viewpoint of manufacturing. Furthermore, it becomes possible to integrally mold the storage body main body of the needle device storage body, which is advantageous in consideration of manufacturing processes and costs.

(7) A flange is provided on the opening end face of the base end portion of the storage body main body, and a shield that can be bonded to the flange and seals the opening of the storage body main body is provided. (4) to (6) above, wherein the space formed by the hollow portion of the container body and the shield is sealed so as to be independent of the external space and maintain sterility.

It becomes possible to form a space independent of the external space in the hollow portion of the main body.
Thereby, the contamination by the foreign material and dust from the external space of the hollow part of the needle device housing can be prevented, and the sterility of the stored needle device and cap can be maintained.
In the aspect of the present invention, since the shield is removed from the collar portion of the opening end face immediately before use and released from the sealed state, the needle device and the cap can be kept sterile until just before use. it can. For this reason, in this aspect, it becomes possible to provide as a product form for use without packaging with other outer packaging materials or the like.

The telescopic tubular member 131 according to the first embodiment of the present invention is preferably a bellows structure. Since the expansion / contraction tubular member 131 has a bellows structure, an operation for contracting the expansion / contraction tubular member 131 in the axial direction can be performed by a pressing operation in one direction, so that the operation is simple and high operability is obtained.
Further, the configuration of the telescopic tubular member 131 is simplified, and the storage body main body 10 having the telescopic tubular member 131 can be integrally formed, which is very advantageous from the viewpoint of manufacturing process and cost. .
The bellows structure in the needle device housing of the present invention is required to have a specific stretchability. In other words, the bellows structure of this aspect is required to have elasticity such that it is contracted by a stress load and restored (extends) to its original shape by releasing the stress load.
Furthermore, the basic characteristics of the bellows structure according to this aspect are to have rigidity as a member, to be capable of linear expansion and contraction in the axial direction, and to be operable with an appropriate operating force during expansion and contraction. It is done. Therefore, by appropriately setting each requirement such as the thickness of the bellows structure, the pitch of the irregularities of the bellows, the expansion / contraction ratio and bending resistance of the bellows structure suitable for this aspect can be obtained, and in the needle device storage body of the present invention It becomes possible to obtain elasticity.

As a result, the distal end of the proximal end hollow member 13 having the opening 15 is moved from the original normal position to the distal end side, and the proximal end portion of the needle base 22 which is a connection site of the stored needle device is exposed. Therefore, the visibility is improved and the connection / disconnection operation can be easily performed.
Further, when the stress load on the distal end of the proximal end hollow member 13 is released, the telescopic tubular member 131 expands and returns to its shape, so that the distal end of the proximal end hollow member 13 is moved from the position on the distal end side to the original position. It can be moved to the normal position.
As a result, the open base end portion of the needle base 22 which is the connection part of the stored needle device can be covered with the base end hollow member 13 of the storage body main body portion 10, so that the storage operation and the disposal operation can be performed. It becomes safer and easier.

The telescopic tubular member 131 has a bellows structure.
Thereby, when the telescopic tubular member 131 is expanded and contracted, the operating force is applied only in the front-rear direction which is the axial direction without being distributed in the vertical and horizontal directions. The contraction / extension movement of the As a result, the contraction / extension operation is simple and the load stress during the operation is small, so that high operability can be obtained. In addition, the configuration of the telescopic tubular member 131 is simplified, the housing body main body 10 of the needle device housing 1 can be formed integrally, and the manufacturing process becomes relatively easy.

Next, a second embodiment to a fourth embodiment of the present invention will be described.
In addition, about the point similar to 1st Embodiment, description regarding 1st Embodiment mentioned above shall be applied suitably, and description was abbreviate | omitted.

As shown in FIG. 3, the needle device housing 1 of the second embodiment of the present invention has a configuration in which the expandable tubular member 131 has a stretchability that can be extended toward the proximal end side in the axial direction as compared to the original shape. This is different from the first embodiment. That is, when the elastic tubular member 131 in the needle device housing 1 of the second embodiment is subjected to stress load (pulling) toward the proximal end in the axial direction, the proximal end of the proximal hollow member 13 is moved toward the proximal end. Move and extend in the axial direction.
