DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0022] As shown in Figures 1 to 5, in the first embodiment of the present disclosure, the door cover 1 is a door cover 1 for a medical pump 2, and the medical pump 2 has a door 2a that can be opened and closed by rotating an infusion tube placement section in which an infusion tube 3 is placed about a first central axis O1 (see the double-headed arrow in Figure 1), and the door 2a has an operated section 2a1 that receives a gripping operation to open the door 2a, and has a locking section 5 that can switch between a locked state (the state shown in Figures 1 and 3) and an unlocked state (the state shown in Figures 4 to 5) by operating a lock 4, and a cover section 6 that covers a part or all (a part in this embodiment) of the operated section 2a1 so as to prevent a gripping operation on the operated section 2a1 in the locked state, and that allows a gripping operation on the operated section 2a1 in the unlocked state by moving from the locked position in the locked state (removed from the medical pump 2 in this embodiment). The shape of the operated part 2a1 is not particularly limited, but in this embodiment, the operated part 2a1 is configured by a lever that can rotate around the second central axis O2 (see the double-headed arrow in FIG. 11), and the door 2a has an insertion recess 2a2 (see FIG. 15) on the back side of the operated part 2a1, into which a finger is inserted for gripping operation. In this embodiment, the medical pump 2 is an infusion pump type, but is not limited thereto, and may be applied to, for example, a syringe pump type. In this embodiment, the first central axis O1 is located at the lower end of the door 2a, and the infusion tube placement part is closed by rotating it upward relative to the medical pump body 2b, and the infusion tube placement part is opened by rotating it downward relative to the medical pump body 2b, but is not limited thereto.

[0023] According to the above configuration, the cover portion 6 can prevent the operation of gripping the operated portion 2a1 in the locked state, and can visually indicate that the gripping operation is prohibited. Therefore, this locking function can prevent unintentional removal of the infusion tube 3 from the medical pump 2 with a simple structure. The door cover 1 of this embodiment is suitable for drug administration that requires strict management, for example, as used in Patient Controlled Analgesia (PCA).

[0024] The door cover 1 has a fixing part 7 that fixes the cover part 6 to the medical pump 2 in a locked state and allows the cover part 6 to move from the locked position in an unlocked state. The lock part 5 is configured by a through part 5a formed by the cover part 6 and the fixing part 7 in a locked state. The lock part 5 is changed from the unlocked state to the locked state by passing the opening / closing part 4a of the lock 4 through the through part 5a and closing it, and the opening / closing part 4a of the lock 4 opens when the lock 4 is unlocked and can be removed from the through part 5a. In this embodiment, the through part 5a is composed of a through hole of the cover part 6 and a through hole of the fixing part 7, but is not limited to this. The opening / closing part 4a of the unlocked lock 4 can be removed from the through part 5a and the cover part 6 is operated relative to the fixing part 7 to change from the locked state to the unlocked state. In this embodiment, the lock 4 is a key type having a lock 4b and a separate key (not shown), but is not limited to this and may be a dial type, for example. In addition, the lock 4 is a padlock in this embodiment, but is not limited thereto, and may be, for example, a carabiner type or a wire type. According to the above configuration, a desired lock 4, including a general-purpose lock that allows the opening / closing part 4a to pass through the through part 5a, can be used in combination with the door cover 1 to realize the lock function. The movement of the cover part 6 from the lock position (i.e., the relative movement between the cover part 6 and the fixing part 7) is a rotational movement around the first rotation axis P1 in this embodiment, but is not limited thereto. In this embodiment, the door cover 1 is configured such that the first rotation axis P1 penetrates both end faces of the door 2a in the left-right direction along the first central axis O1 (more specifically, extends along the left-right direction), but is not limited thereto, and as in the ninth embodiment shown in Figs. 22 to 24, the movement of the cover part 6 from the lock position may be a rotational movement around the sixth rotation axis P that penetrates both end faces of the door 2a in the front-rear direction (more specifically, extends along the front-rear direction).

[0025] As in the second embodiment shown in Figs. 7 to 9, the door cover 1 has a fixing portion 7 that fixes the cover portion 6 to the medical pump 2 in the locked state and allows the cover portion 6 to move from the locked position in the unlocked state, the lock portion 5 is configured by a lock 4 formed by the cover portion 6 and the fixing portion 7, and the cover portion 6 may have a keyhole 4c for the lock 4. With the above configuration, it is not necessary to prepare a lock 4 separately from the medical pump 2 and the door cover 1. In this embodiment, the movement of the cover portion 6 from the locked position is a rotational movement about the second rotation axis P2, but the present invention is not limited to this. For example, as in the fifth embodiment shown in Figs. 15 to 16, the movement of the cover portion 6 from the locked position may be a sliding movement.

[0026] In the second embodiment, the keyhole 4c can move between a keyhole locked position where the keyhole is in a locked state from an unlocked state and a keyhole unlocked position where the keyhole is in a unlocked state from a locked state, and holds the key 4d in the keyhole unlocked position. According to the above configuration, since the keyhole 4c holds the key 4d in the keyhole unlocked position, it is possible to prevent the key 4d from falling out of the keyhole 4c when the cover part 6 moves from the locked position in the unlocked state.

[0027] As in the third embodiment of the present disclosure shown in Figs. 10-11, the door cover 1 has a fixing portion 7 that fixes the cover portion 6 to the medical pump 2 in the locked state and allows the cover portion 6 to move from the locked position in the unlocked state, and the lock portion 5 is configured by a lock 4 formed by the cover portion 6 and the fixing portion 7, and the fixing portion 7 may have a key hole 4c of the lock 4. According to the above configuration, since the key hole 4c is in the fixing portion 7, it is possible to prevent the key 4d from falling out of the key hole 4c when the cover portion 6 moves from the locked position in the unlocked state. In this embodiment, the movement of the cover portion 6 from the locked position is a rotational movement around the third rotation axis P3, but this is not limited to this. In the fifth embodiment shown in Figs. 15-16, since the movement of the cover portion 6 from the locked position is a sliding movement, the key 4d does not fall out of the key hole 4c, but the key hole 4c is provided in the fixing portion 7. However, as in a sixth embodiment shown in FIG. 17, the keyhole 4c may be provided in the cover portion 6. In the sixth embodiment shown in FIG.

[0028] As in the fourth embodiment shown in Fig. 12 to Fig. 14, the fifth embodiment shown in Fig. 15 to Fig. 16, the sixth embodiment shown in Fig. 17, the seventh embodiment shown in Fig. 18 to Fig. 19, and the eighth embodiment shown in Fig. 20 to Fig. 21, the operated portion 2a1 may be configured as a lever, the door 2a may have an insertion recess 2a2 on the back side of the operated portion 2a1 into which a finger is inserted for a gripping operation, and the door cover 1 may have an insertion portion 8 that is located in the insertion recess 2a2 in the locked state. According to the above configuration, the insertion recess 2a2 can be blocked by the insertion portion 8 to prevent a finger from being inserted into the insertion recess 2a2 for a gripping operation. In this embodiment, the operation of inserting the insertion portion 8 into the insertion recess 2a2 (i.e., the relative operation between the cover portion 6 and the fixed portion 7) is a rotation operation about the fourth rotation axis P4 penetrating both end surfaces of the door 2a in the front-rear direction, but the present invention is not limited to this. For example, as in the fifth to eighth embodiments, the operation of inserting the insertion portion 8 into the insertion recess 2a2 (i.e., the relative operation between the cover portion 6 and the fixed portion 7 in the fifth to sixth embodiments) may be a sliding operation. Note that, in the fifth to sixth embodiments, the relative operation between the cover portion 6 and the fixed portion 7 is a sliding operation in the left-right direction (more specifically, a sliding operation along the left-right direction), but the present invention is not limited to this. As in the seventh embodiment, the relative operation between the cover portion 6 and the fixed portion 7 may be a sliding operation in the up-down direction (more specifically, a sliding operation along the up-down direction).

[0029] As in the eighth embodiment shown in Figs. 20-21, the locking unit 5 may be configured with a lock 4 formed by the door cover 1 and the door 2a. With the above configuration, there is no need to prepare a lock 4 separately from the medical pump 2 and the door cover 1. Also, the door cover 1 can be easily attached to the medical pump 2. In this embodiment, the operation of locking the lock 4 is a rotation operation about the fifth rotation axis P5, but this is not limited to the configuration.

[0030] In the first to eighth embodiments, the cover portion 6 has a locking portion 6a that can be hooked and locked to the door 2a in the locked state and can release the locking to the door 2a in the unlocked state. According to the above configuration, the cover portion 6 can be held in the locked position by the locking portion 6a in the locked state, so that the cover portion 6 can be configured with a simple structure.

[0031] In the first to eighth embodiments, the locking portion 6a has a claw 6a1 that can be locked to the edge of the door 2a. According to the above configuration, the locking portion 6a can be configured with a simple structure.

[0032] In the first to eighth embodiments, in the unlocked state, the cover part 6 can be held by the medical pump 2. According to the above configuration, it is possible to prevent the cover part 6 from falling off the medical pump 2 when the cover part 6 is in the unlocked state.

[0033] In the first to ninth embodiments, the door cover 1 is attached to the medical pump 2. According to the above configuration, by attaching the door cover 1 to an existing medical pump 2, unintentional removal of the infusion tube 3 can be prevented.

[0034] In the first to ninth embodiments, the medical pump device 9 is composed of a set of a medical pump 2 and a door cover 1. According to the above configuration, it is possible to realize the medical pump device 9 that can prevent unintentional removal of the infusion tube 3 from the medical pump 2 with a simple structure.

[0035] 6, in the first embodiment, the rack system 10 has a medical pump device 9 and a rack 11 on which the medical pump device 9 is mounted. In the present embodiment, the rack 11 is configured to be capable of mounting up to three medical pump devices 9, but the number of medical pump devices 9 that can be mounted on the rack 11 can be set as appropriate. With the above configuration, it is possible to realize a rack system 10 that can prevent unintentional removal of the infusion tube 3 from the medical pump 2 with a simple structure.
