[0014] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0015] As shown in FIG. 1 , a pump cover 1 according to a first embodiment of the present disclosure is a pump cover 1 for a medical pump 2 having a main body 3 and an opening / closing part 4. The medical pump 2 is, for example, an infusion pump for intravenous administration or enteral nutrition. The opening / closing part 4 has a front panel 5 having a display 5a and an input operation part 5b consisting of buttons. Note that the input operation part 5b is not limited to being composed of buttons. The opening / closing part 4 is not limited to being composed of a front panel 5.

[0016] In this specification, the up-down direction D1 coincides with the vertical direction when the medical pump 2 is in use.

[0017] The opening / closing unit 4 can be opened and closed by rotating relative to the main body 3 around a rotation axis O extending in the vertical direction D1. Note that the opening / closing unit 4 is not limited to a configuration in which the rotation axis O extends in the vertical direction D1, and may be configured, for example, so that the rotation axis O extends horizontally. The opening / closing unit 4 is not limited to a configuration in which it can be opened and closed by rotating, and may be configured, for example, so that it can be opened and closed by sliding. Furthermore, the opening / closing unit 4 is held by the main body 3 so that it can be opened and closed. Note that the opening / closing unit 4 is not limited to this, and may be configured so that it can be attached to and detached from the main body 3. In other words, the opening / closing unit 4 may be closed by attaching it to the main body 3, and opened by removing it from the main body 3.

[0018] As shown in FIGS. 1 and 2, the opening-closing part 4 forms a boundary 6 between the main body 3 and the opening-closing part 4 when the opening-closing part 4 is closed. The main body 3 has a handle part 7 that extends elongatedly in a direction across the boundary 6 in a top view (hereinafter, for convenience of explanation, also referred to as the front-to-back direction D2). The upper surface of the handle part 7 forms part of the upper surface of the main body 3. A bag-shaped or bottle-shaped container that contains a liquid to be delivered by the medical pump 2 is disposed above the medical pump 2, and a liquid delivery tube 8 extending from the container is passed through the medical pump 2. More specifically, the liquid delivery tube 8 is disposed so as to pass through a through-hole 6a that passes through the boundary 6 in the up-down direction D1 on the upper surface of the medical pump 2.

[0019] As shown in FIG. 3, the pump cover 1 has an upper cover 9, a lower cover 10, and fixing screws 11.

[0020] The pump cover 1 also has a screw fixing portion 12 consisting of a part of the upper cover 9 and a part of the lower cover 10 that are fixed to each other by a fixing screw 11. The fixing screw 11 has an engaging recess 11a that can engage with a screwdriver. The part of the upper cover 9 that constitutes the screw fixing portion 12 has a through hole 12a in which the fixing screw 11 is placed when the cover is fixed with the fixing screw 11, and the part of the lower cover 10 that constitutes the screw fixing portion 12 has an engaging hole 12b that screws into the fixing screw 11 when the cover is fixed. Note that the configuration of the screw fixing portion 12 is not limited to this, and for example, the positions of the through hole 12a and the engaging hole 12b may be reversed.

[0021] The pump cover 1 also has a fitting portion 13 made up of a part of the upper cover 9 and a part of the lower cover 10, which can be displaced relative to each other in the longitudinal direction of the handle portion 7 (i.e., the front-to-rear direction D2) when the screw fixing portion 12 is released, thereby enabling the upper cover 9 and the lower cover 10 to be detached from the handle portion 7. The part of the upper cover 9 that constitutes the fitting portion 13 is made up of two pairs of convex portions 13a that face each other in the width direction D3 that is perpendicular to the longitudinal direction in a top view, and the part of the lower cover 10 that constitutes the fitting portion 13 is made up of two pairs of groove portions 13b that face each other in the width direction D3. Note that the configuration of the fitting portion 13 is not limited to this, and for example, the positions of the convex portions 13a and the groove portions 13b may be interchanged, or the number of convex portions 13a and groove portions 13b may be changed.

[0022] The pump cover 1 can be removed from the handle portion 7 by releasing the screw fixing portion 12 from the attached state in which the pump cover 1 is attached to the handle portion 7, releasing the engagement of the engagement portion 13, and detaching the upper cover 9 and the lower cover 10 from the handle portion 7.

[0023] The upper cover 9 has an upper handle cover portion 9a and an upper extension cover portion 9b. In the attached state, the upper handle cover portion 9a covers at least the longitudinal center portion of the upper surface of the handle portion 7. In the attached state, the upper extension cover portion 9b extends from one end of the upper handle cover portion 9a on the boundary 6 side in the longitudinal direction, over the boundary 6, toward the front opening / closing portion 4. In addition, in the attached state, the upper extension cover portion 9b extends from one end of the upper handle cover portion 9a on the boundary 6 side in the longitudinal direction to both the left and right directions perpendicular to both the up-down direction D1 and the front-to-back direction D2. In the attached state, the upper extension cover portion 9b partially covers the boundary 6 in a top view. Note that the upper extension cover portion 9b may be configured to cover the entire boundary 6 in a top view in the attached state.

[0024] The upper extension cover portion 9b has a cutout portion 14 and a liquid guide portion 15. As shown in FIG. 4, the liquid supply tube 8 passes through the cutout portion 14. The liquid guide portion 15 is a flow path that guides the flow of liquid that has descended onto the upper surface to areas other than the boundary 6. In other words, the liquid guide portion 15 prevents the liquid that has descended onto the upper surface of the liquid guide portion 15 from flowing to the boundary 6. To this end, the liquid guide portion 15 has a restricting rib 15a that protrudes upward and is provided along the edge of the upper extension cover portion 9b so that the curved convex portion protrudes forward in a top view and has a slit-like apex corresponding to the cutout portion 14. The restricting rib 15a guides the flow of liquid that has descended onto the upper surface of the liquid guide portion 15 to both left and right sides of the upper handle cover portion 9a.

[0025] For example, liquid such as nutrients leaking from a container may flow down the liquid delivery tube 8 or directly from the container near the through-hole 6a of the boundary 6. If such liquid enters the interior of the medical pump 2 through the boundary 6, it may become contaminants that are difficult to remove. Furthermore, such liquid may contain infectious substances, which may enter the interior of the medical pump 2 and delay removal, potentially leading to the spread of infection. However, as shown by the bold arrows in Figure 4, the liquid guide 15 directs the descending liquid to areas other than the boundary 6, thereby preventing the liquid from entering the interior of the medical pump 2 through the boundary 6.

[0026] The upper cover 9 further has a restricting protrusion 9c that restricts liquid that has fallen onto the upper surface of the upper extension cover portion 9b from flowing up to the upper handle cover portion 9a.

[0027] Furthermore, for example, when an infusion pump for intravenous administration and an infusion pump for enteral nutrition are used together, the pump cover 1 can be placed so that it is easily visible on only one of the infusion pumps, making it easy to identify the infusion pumps. The color of the pump cover 1 can be set appropriately taking into consideration ease of identification. Pump covers 1 of different colors can be attached to both infusion pumps to make identification easier. This makes it possible to identify the type of drug and the patient, which has the effect of reducing medical errors such as mix-ups and alerting users to the dangers of dangerous drugs.

[0028] According to this embodiment, the pump cover 1 is placed on the medical pump 2 so as to at least partially cover the boundary 6 when viewed from above when the opening / closing section 4 is closed, thereby preventing liquid from entering the interior of the medical pump 2 through the boundary 6.

[0029] Furthermore, according to this embodiment, the liquid guide portion 15 can further prevent the liquid from entering the interior of the medical pump 2 through the boundary 6.

[0030] Furthermore, according to this embodiment, by passing the fluid delivery tube 8 through the cutout portion 14, it becomes easier to catch the liquid that descends along the fluid delivery tube 8, and as a result, it is possible to further prevent the liquid from entering the interior of the medical pump 2 through the boundary 6.

[0031] Furthermore, according to this embodiment, the upper handle cover portion 9a is disposed in an easily visible position, making it possible to easily identify the medical pump 2.

[0032] Furthermore, according to this embodiment, the restricting protrusions 9c can prevent liquid dripping onto the upper surface of the upper extension cover portion 9b from flowing down to the upper handle cover portion 9a and contaminating the upper handle cover portion 9a, which serves as the gripping portion. This also reduces the risk of the medical pump 2 dropping and resulting damage when the hand is easily slippery due to dripping liquid and the medical pump 2 is transported while gripping the upper handle cover portion 9a. Furthermore, there is a risk of infection transmitted by dripping liquid, and preventing the upper handle cover portion 9a from becoming contaminated can help prevent the spread of infection within a hospital. Therefore, preventing the upper handle cover portion 9a from becoming contaminated by the restricting protrusions 9c can help prevent medical accidents, equipment failure, and the spread of infection within a hospital in medical settings.

[0033] Furthermore, according to this embodiment, a screwdriver is required to remove the pump cover 1 from the medical pump 2, which prevents the pump cover 1 from being removed from the medical pump 2 in the medical field, thereby maintaining good identification of the medical pump 2. Furthermore, if necessary, an administrator with a screwdriver can easily remove the pump cover 1 by releasing the fixation of the screw fixing portion 12 and the engagement of the engagement portion 13, and can also easily attach the pump cover 1 by performing the reverse operations.

[0034] Furthermore, as shown in FIGS. 5 and 6, an adhesive member 16 made of, for example, a film may be provided to be attached to the front panel 5 to enhance its distinguishability. The adhesive member 16 may have a color, a pattern, or a combination thereof to enhance its distinguishability. In this case, the color, pattern, etc. may correspond to a characteristic such as the color of the pump cover 1. In other words, when the pump cover 1 is placed on the top surface of the medical pump 2, the adhesive member 16 on the front panel 5 makes it easy to distinguish the pump cover 1 even when viewed from below, where the pump cover 1 may be in a blind spot. This improves the distinguishability of the medical pump 2.

[0035] The pump cover 1 of the second embodiment shown in FIG. 7 is for a medical pump 2 similar to that of the first embodiment. In the second embodiment, the pump cover 1 is placed on the medical pump 2 so that it at least partially covers the boundary 6 in a top view when the opening / closing part 4 is closed. When attaching the pump cover 1 to the medical pump 2, it may be attached using adhesive tape or a pressure-sensitive adhesive other than the screw fixing part 12. In this case, an adhesive that can be attached and removed multiple times may be appropriately selected. Furthermore, the pump cover 1 may be made of disposable materials and priced to be disposable, allowing it to be frequently replaced for the purpose of preventing infection in hospitals.

[0036] The pump cover 1 of this embodiment has a top surface portion 17, a pair of side surfaces 18, and a rear surface portion 19. When the pump cover 1 is placed on the medical pump 2, the top surface portion 17 covers the entire main body portion 3 and part of the boundary 6 in a top view. One side surface portion 18 extends downward from one edge of the top surface portion 17 in the left-right direction in the placed state, and the other side surface portion 18 extends downward from the other edge of the top surface portion 17 in the left-right direction in the placed state. The rear surface portion 19 extends downward from the rear edge of the top surface portion 17 in the placed state.

[0037] The top surface portion 17 has a pair of inclined surface portions 17a connected via a ridge line portion 20 extending in the front-rear direction D2 at the center in the left-right direction. One of the inclined surface portions 17a is inclined downward from the ridge line portion 20 toward one side in the left-right direction, and the other inclined surface portion 17a is inclined downward from the ridge line portion 20 toward the other side in the left-right direction. The pair of inclined surface portions 17a, the pair of side surface portions 18, and the rear surface portion 19 are each flat.

[0038] Each inclined surface portion 17a has a front end portion 17b located forward of the front end of the side surface portion 18 adjacent to that inclined surface portion 17a in a top view. A notch portion 14 is provided between the front end portions 17b of the pair of inclined surface portions 17a, through which the liquid supply tube 8 passing through the boundary 6 is passed. The front end portions 17b of the pair of inclined surface portions 17a cover the entire portion of the boundary 6 except for the through-hole 6a in the top view. As shown by the thick arrows in FIG. 7, the front end portions 17b of the pair of inclined surface portions 17a function as a liquid guide portion 15 that guides the flow of liquid that has descended onto the upper surface to portions other than the boundary 6. The pair of inclined surface portions 17a also function as an upper handle cover portion 9a that covers at least the longitudinal center portion of the upper surface of the handle portion 7.

[0039] The pump cover 1 of the third embodiment shown in Figure 8 differs from that of the second embodiment only in that the upper surface portion 17 has a cutout 21 in a portion corresponding to at least the longitudinal center portion of the upper surface of the handle portion 7. In other words, the pump cover 1 of the third embodiment differs from that of the second embodiment only in that it does not have an upper handle cover portion 9a.

[0040] The pump cover 1 of the fourth embodiment shown in FIGS. 9 to 13 is a pump cover 1 for a medical pump 2 having a different configuration from the medical pump 2 of the first embodiment.

[0041] The medical pump 2 of the fourth embodiment has a main body 3, an opening / closing unit 4, and a clamp unit 22. The opening / closing unit 4 is openably and closably provided on the lower front surface of the main body 3. More specifically, as indicated by the thick bidirectional arrow in FIG. 12 , the opening / closing unit 4 is openably and closably provided by rotating relative to the main body 3 about a rotation axis O extending in the left-right direction at the lower end of the opening / closing unit 4. When the opening / closing unit 4 is closed, the opening / closing unit 4 forms a boundary 6 between the main body 3 and the opening / closing unit 4. Note that the opening / closing unit 4 is not limited to a configuration in which the rotation axis O extends in the left-right direction, and may be configured, for example, so that the rotation axis O extends in the up-down direction D1. The opening / closing unit 4 is not limited to a configuration in which it can be opened and closed by rotation, and may be configured, for example, so that it can be opened and closed by sliding.

[0042] The upper front surface of the main body 3 is an inclined surface that slopes downward and forward. The front panel 5 is provided on the upper front surface of the main body 3, not on the opening / closing unit 4. One side of the main body 3 has a dial 23. Note that the configuration may not include the dial 23. The clamp unit 22 is provided on the rear surface of the main body 3. Note that the configuration may not include the clamp unit 22. The medical pump 2 of this embodiment is, for example, an infusion pump for intravenous administration or enteral nutrition.

[0043] The pump cover 1 of this embodiment is placed on the medical pump 2 so that it covers the entire boundary 6 when viewed from above when the opening / closing part 4 is closed. When attaching the pump cover 1 to the medical pump 2, it may be attached using adhesive tape or a glue other than the screw fixing part 12. In this case, an adhesive that can be removed and attached multiple times may be selected as appropriate. Furthermore, the pump cover 1 may be made of disposable materials and priced to be disposable, allowing it to be replaced frequently to prevent infection within the hospital.

[0044] The pump cover 1 of this embodiment has a top surface portion 17, a front surface portion 24, a pair of side surface portions 18, and a rear surface portion 19. The top surface portion 17 covers the top surface of the main body portion 3 in a top view when in the deployed state. The front surface portion 24 covers the entire upper front surface of the main body portion 3 and the entire boundary line 6 in a top view when in the deployed state. As shown by the thick arrow pointing in one direction in FIG. 12 , the front surface portion 24 functions as a liquid guide portion 15 that guides the flow of liquid that has descended onto the top surface to an area other than the boundary line 6. In this embodiment, the liquid guide portion 15 guides the flow of liquid that has descended onto the top surface of the liquid guide portion 15 to an area below the boundary line 6. One side surface portion 18 extends downward from one edge of the top surface portion 17 in the left-right direction when in the deployed state, and the other side surface portion 18 extends downward from the other edge of the top surface portion 17 in the left-right direction when in the deployed state. The side surface portion 18 arranged on the dial 23 side covers the dial 23 from the side when in the deployed state. The rear surface portion 19 extends downward from the rear end edge of the upper surface portion 17 in the deployed state, and is provided so as to expose the clamp portion 22.

[0045] Pump cover 1 is a soft cover that is flexible enough to allow front portion 24 and side portion 18 to be rolled up. The user can easily operate front panel 5 by rolling up front portion 24 as shown by the thick arrow in Fig. 10. The user can also easily operate dial 23 by rolling up side portion 18 located on the dial 23 side as shown by the thick arrow in Fig. 11.

[0046] The pump cover 1 of the fifth embodiment shown in Figures 14 to 17 is a pump cover 1 for a medical pump 2 similar to that of the fourth embodiment. In the fifth embodiment, the pump cover 1 is a hard-type cover, and a front portion 24 is supported on a cover body 26 via a hinge portion 25 so as to be rotatable about an axis extending in the left-right direction. The cover body 26 has a top surface portion 17, a pair of side surfaces 18, and a rear surface portion 19. The side surface portion 18, which is disposed on the dial 23 side, is provided so as to expose the dial 23 when in the deployed state. The other configurations of the pump cover 1 are the same as those of the fourth embodiment.

[0047] The user can easily operate the front panel 5 by rotating and lifting the front part 24 as shown by the thick arrow in Figure 15. Furthermore, the user can easily operate the dial 23 because the side part 18 arranged on the dial 23 side exposes the dial 23.

[0048] The present disclosure is not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the present disclosure.

[0049] Therefore, the pump cover 1 according to the above-described embodiment can be modified in various ways as long as it is a pump cover 1 for a medical pump 2 having a main body 3 and an opening / closing part 4, and is placed on the medical pump 2 so as to at least partially cover the boundary 6 between the main body 3 and the opening / closing part 4 when viewed from above when the opening / closing part 4 is closed.
