Medical equipment

Technical Field

The application relates to the technical field of medical equipment, in particular to medical equipment.

Background

In the related art, a waterproof design of a medical device is generally implemented by using a material having sealing properties such as foam or silica gel to achieve waterproof by means of positive structural pressure, for example, referring to fig. 1, in order to prevent a liquid 05 from flowing into the medical device from a gap between a first member 01 and a second member 02, a waterproof sealing member 03 is added between the first member 01 and the second member 02, and the sealing member 03 is pressed by a positive pressure F1 acting on the second member 02, such as a positive pressure F1 applied to the second member 02 by a screw 04 fastened to the second member 02, so that the sealing member 03 is in close contact with the second member 02 to achieve waterproof.

However, this design method makes it impossible to achieve an effective waterproof purpose by means of a side pressure waterproof structure, for example, referring to fig. 2, a side pressure F2 is provided on one side of the second member 02, but the sealing member 03 is not pressed by a positive pressure above the second member 02, the sealing member 03 cannot be in close contact with the second member 02, and the liquid 05 easily enters the inside of the medical device along a gap between the sealing member 03 and the second member 02.

Disclosure of Invention

In view of this, it is desirable to provide a medical device having a good waterproof effect under lateral pressure.

To achieve the above object, embodiments of the present application provide a medical device including:

a housing provided with a receiving chamber having an opening;

the sealing piece comprises a substrate and a sealing rib, one end of the sealing rib is connected with the substrate, and one end of the sealing rib, which is away from the substrate, is a free end; the sealing piece is arranged on the shell, a diversion trench is defined between the sealing piece and the shell, and the diversion trench is positioned at one side of the sealing piece, which is away from the opening;

the cover plate translates towards the direction where the diversion trench is located from one side of the sealing rib, which is away from the diversion trench, under the action of external force so as to push the sealing rib to bend towards one side where the diversion trench is located; when the cover plate is in a closed state for closing the opening, the cover plate is in sealing contact with the bent sealing ribs, so that sealing is realized between the cover plate and the shell at least in the area where the sealing element is arranged.

The embodiment of the application provides medical equipment, and the sealing piece that has basement and sealing rib has been set up on the casing to this medical equipment, prescribes a limit to the guiding gutter between sealing piece and the casing, and the guiding gutter is located the side of the opening of the holding chamber of sealing piece facing away from the casing. The cover plate moves horizontally in the direction of the diversion trench from one side of the sealing rib, which is away from the diversion trench, under the action of external force, so that the sealing rib can be pushed to bend towards one side of the diversion trench, namely, the sealing rib bends towards one side of the diversion trench under the action of lateral pressure of the cover plate. When the cover plate is in a closed state for closing the opening, the cover plate is in sealing contact with the bent sealing rib. Because the sealing rib is bent towards one side where the guide groove is located under the lateral pressure effect of the cover plate, the cover plate and the bent sealing rib can be in close contact with each other, when external liquid flows from one side of the sealing element away from the opening to the opening, the sealing element can better intercept the liquid, and the liquid is not easy to flow from between the cover plate and the sealing rib to one side of the sealing element close to the opening, so that the sealing element can have better waterproof effect under the action of the lateral pressure.

Detailed Description

Embodiments of the present application provide a medical device of the type that is not limited, and the medical device shown in fig. 3 is illustratively a medical infusion pump.

Referring to fig. 3 to 10, the medical device includes a housing 10, a seal 20, and a cover 40.

The housing 10 is provided with a receiving chamber 10b having an opening 10 a. The housing chamber 10b is a chamber for housing the medical device in its internal structure including, but not limited to, a motherboard, components, structural members, and the like.

The sealing member 20 includes a base 21 and a sealing rib 22, wherein one end of the sealing rib 22 is connected to the base 21, and one end of the sealing rib 22 facing away from the base 21 is a free end, that is, one end of the sealing rib 22 facing away from the base 21 is a freely movable end. The sealing member 20 is disposed on the housing 10, and a flow guiding groove 30 is defined between the sealing member 20 and the housing 10, the flow guiding groove 30 is used for guiding external liquid, and the flow guiding groove 30 is located at one side of the sealing member 20 away from the opening 10 a.

The substrate 21 may be directly placed on the housing 10, or may be fixed to the housing 10 by adsorption, adhesion, or the like.

The sealing rib 22 may be a solid structure or a hollow structure.

At least one of the opposite ends of the guide groove 30 along the extending direction may be communicated with the outside, so that the liquid flowing into the guide groove 30 may flow out from the communication between the guide groove 30 and the outside and naturally flow to the ground under the action of self gravity.

The cover plate 40 is moved by an external force in a translational motion from the side of the sealing rib 22 away from the flow guide groove 30 toward the flow guide groove 30 (i.e., in a direction indicated by an arrow at F2 in fig. 8) to push the sealing rib 22 to bend toward the side of the flow guide groove 30. When the cover 40 is in a closed state closing the opening 10a, the cover 40 is in sealing contact with the curved sealing rib 22, so that sealing is achieved between the cover 40 and the housing 10 at least at the portion where the sealing rib 22 is provided.

Specifically, referring to fig. 8, an external force that translates the cover 40 from the side of the sealing rib 22 away from the flow guiding groove 30 toward the flow guiding groove 30 is actually a lateral pressure F2 acting on the cover 40, the external force pushes the cover 40 to translate, and the cover 40 pushes the sealing rib 22 to bend toward the side of the flow guiding groove 30, which is equivalent to bending the sealing rib 22 toward the side of the flow guiding groove 30 under the action of the lateral pressure F2 of the cover 40. When the cover 40 is in a closed state closing the opening 10a, i.e., the cover 40 is provided at the opening 10a, the sealing rib 22 remains in a bent state by the side pressure F2 of the cover 40, and the cover 40 is in sealing contact with the sealing rib 22 which remains in the bent state.

In addition, the sealing between the cover 40 and the housing 10 at least in the area where the seal 20 is provided means that the seal 20 is provided between the cover 40 and the housing 10, and other areas where the seal 20 is not provided may be provided with other sealing structures according to actual needs, or the cover 40 may be directly abutted against the housing 10, that is, other areas where the seal 20 is not provided may be sealed by other means, or may not be sealed.

That is, the medical device of the embodiment of the present application is that the sealing member 20 having the base 21 and the sealing rib 22 is provided on the housing 10, the flow guiding groove 30 is defined between the sealing member 20 and the housing 10, and the flow guiding groove 30 is located at a side of the sealing member 20 facing away from the opening 10a of the accommodating chamber 10b of the housing 10. The cover plate 40 can push the sealing rib 22 to bend towards the side of the flow guiding groove 30 by translating towards the direction of the flow guiding groove 30 from the side of the sealing rib 22 away from the flow guiding groove 30 under the action of external force, namely, the sealing rib 22 bends towards the side of the flow guiding groove 30 under the action of the lateral pressure F2 of the cover plate 40. When the cover 40 is in a closed state closing the opening 10a, the cover 40 is in sealing contact with the curved sealing rib 22. Because the sealing rib 22 is bent towards the side where the diversion trench 30 is located under the action of the lateral pressure F2 of the cover plate 40, the cover plate 40 and the bent sealing rib 22 can be in close contact, when external liquid flows from the side of the sealing element 20 away from the opening 10a to the opening 10a, the sealing element 20 can better intercept the liquid, and the liquid is not easy to flow from the position between the cover plate 40 and the sealing rib 22 to the side of the sealing element 20 close to the opening 10a, so that the sealing element 20 can have better waterproof effect under the action of the lateral pressure F2.

In an embodiment, referring to fig. 5, 8 and 10, the number of the sealing ribs 22 may be plural, and the plural sealing ribs 22 are disposed at intervals from a side of the substrate 21 close to the flow guiding groove 30 to a side of the substrate 21 away from the flow guiding groove 30.

Specifically, the seal 20 in fig. 5 is provided with two seal beads 22, and in other embodiments, the number of seal beads 22 may be greater than two. Providing a plurality of seal bars 22 may perform multiple interception functions, for example, taking the seal 20 shown in fig. 5, 8 and 10 as an example, for convenience of description, two seal bars 22 may be referred to as a first seal bar 22a and a first seal bar 22b, where the first seal bar 22a is located at a side of the first seal bar 22b facing away from the opening 10a, and if in an unexpected situation, the liquid passes over the first seal bar 22a, the first seal bar 22b may further intercept the liquid again, thereby further improving the sealing effect of the seal 20.

It will be appreciated that in some embodiments, the seal 20 may be provided with only one sealing bead 22.

In one embodiment, referring to fig. 5, 8 and 10, the cross section of the sealing rib 22 gradually decreases from the end connected to the base 21 toward the free end, that is, the sealing rib 22 may have a relatively thick end near the base 21 and a relatively thin end, so that the sealing rib 22 may have a better strength and may be easily bent under the lateral pressure of the cover 40.

In one embodiment, referring to fig. 5, 8 and 10, the housing 10 has a first side wall 10c1, the first side wall 10c1 is located on a side of the sealing member 20 facing away from the opening 10a, the flow guiding groove 30 is located between the first side wall 10c1 and the sealing member 20, and the first side wall 10c1 forms a side wall of the flow guiding groove 30 facing away from the sealing rib 22.

Specifically, the base 21 of the seal 20 in fig. 5, 8 and 10 is spaced from the first sidewall 10c1, and in other embodiments, the base 21 of the seal 20 may abut against the first sidewall 10c 1. The side wall of the first sealing rib 22a facing away from the opening 10a corresponds to the side wall of the other side of the flow guide groove 30.

In one embodiment, referring to fig. 5, 8 and 10, the housing 10 has a first step 10c and a second step 10d extending toward the opening 10a, the first step 10c has a first sidewall 10c1, the sealing member 20 is disposed on a side of the second step 10d facing away from the first step 10c, the base 21 abuts against the second step 10d, and the step surface 10d1 of the second step 10d at least forms a part of the bottom wall of the flow guiding groove 30.

Specifically, the base 21 of the seal 20 in fig. 5, 8 and 10 has a partial structure protruding from the side of the first bead 22a facing away from the opening 10a, and the top end surface corresponding to the region of the base 21 protruding from the side of the first bead 22a facing away from the opening 10a and the step surface 10d1 of the second step 10d together constitute the bottom wall of the flow guide groove 30. In other embodiments, the side wall of the base 21 facing away from the opening 10a may be flush with the side wall of the first sealing rib 22a facing away from the opening 10a, which corresponds to the step surface 10d1 of the second step 10d alone forming the bottom wall of the flow guiding groove 30.

The second step 10d may provide a certain positioning function for the sealing member 20 to facilitate the installation of the sealing member 20.

Further, referring to fig. 5, 8 and 10, a positioning rib 10e may be further disposed on the housing 10, where the positioning rib 10e is located between the base 21 and the opening 10a, and the positioning rib 10e cooperates with the second step 10d to position the base 21.

The number of the positioning ribs 10e may be plural, the plural positioning ribs 10e may be arranged at intervals, and the number of the positioning ribs 10e may be one.

Although the second step 10d may have a certain positioning effect on the sealing member 20, the sealing member 20 may also be shifted in a direction away from the second step 10d during long-term use, and thus, by providing the positioning ribs 10e, the substrate 21 may be positioned on opposite sides of the substrate 21, and thus, the positional shift of the sealing member 20 may be preferably avoided.

In another embodiment, referring to fig. 11 and 12, no matter whether the second step 10d is provided, the side of the substrate 21 facing away from the sealing rib 22 may be provided with the first positioning portion 21a, meanwhile, the housing 10 is provided with the second positioning portion 10f, in fig. 12, the first positioning portion 21a is a positioning protrusion, the second positioning portion 10f is a positioning groove, in other embodiments, the first positioning portion 21a may be a positioning groove, the second positioning portion 10f is a positioning protrusion, and the positioning protrusion may also have a better positioning effect on the sealing element 20 by extending into the positioning groove.

In an embodiment, referring to fig. 5, 8 and 10, for the housing 10 provided with the first step 10c, the cover 40 may rest on the step surface 10c2 of the first step 10c when the cover 40 is in the closed state, regardless of whether the housing 10 is provided with the second step 10 d.

The first step 10c may support the cover 40 to improve the reliability of the sealing contact of the cover 40 with the curved sealing rib 22.

In some embodiments, when the cover 40 is in the closed state, the cover 40 may not rest on the step surface 10c2 of the first step 10 c.

In an embodiment, referring to fig. 5, 8 and 10, the housing 10 has an appearance surface 10g located on a side of the first step 10c away from the diversion trench 30 and a second side wall 10h connected to the appearance surface 10g, when the cover 40 is in a closed state, the cover 40 and the second side wall 10h are spaced apart, so that a diversion trench 10i communicating with the outside is formed at the spacing, and a liquid path passing through the first step 10c is formed between the diversion trench 10i and the diversion trench 30.

Specifically, the drainage groove 10i can play a role of converging the liquid flowing to the outer surface of the appearance surface 10g or the cover plate 40, that is, the liquid flowing to the outer surface of the appearance surface 10g or the cover plate 40 can flow into the drainage groove 10i and then flow downwards from the drainage groove 10i into the diversion groove 30, thereby better avoiding the accumulation of the external liquid on the outer surface of the appearance surface 10g or the cover plate 40.

Further, referring to fig. 5, 8 and 10, the housing 10 further has a third step 10j located between the second side wall 10h and the first step 10c, and when the cover 40 is in the closed state, the cover 40 abuts against the third step 10 j.
