Based on the embodiments in the embodiment, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention.

In the following description, the terms "inside", "outside", "upper", "lower", "left", "right", and the like, which indicate orientations or positional relationships, are used to indicate orientations or positional relationships based on the drawings, and are only used for convenience in describing embodiments and simplifying the description, but do not indicate or imply that the indicated device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

The first embodiment is as follows:

as shown in fig. 1 to 5, the present embodiment shows a medical hand controller, which is mainly applied in a ward and used for controlling some medical devices, and includes a housing, a circuit board 5 and a flexible key pad 4, the circuit board 5 and the flexible key pad 4 are disposed in the housing, the housing includes an upper casing 2 and a lower casing 3, a hook 31 for hanging is disposed at an end of the lower casing 3, and the hook 31 can be generally hung at a position such as a guardrail of a medical bed. The circuit board 5, flexible key pad 4 holding are in the space that last casing 2 and lower casing 3 concatenation formed, upward be equipped with the key hole 21 on the casing 2, upward casing 2 is equipped with waterproof card muscle 22 in the round towards the protruding 4 one sides of flexible key pad, interior waterproof card muscle 22 is located the periphery of key hole 21, flexible key pad 4 is extruded between interior waterproof card muscle 22 and circuit board 5, the outer lane of going up casing 2 and the outer lane concatenation department of casing 3 down are equipped with outer seal ring 6.

When the waterproof improvement is carried out, the inner waterproof and the outer waterproof are mainly improved, the outer waterproof is mainly realized by the outer sealing ring 6 between the upper shell 2 and the lower shell 3, the inner waterproof is mainly realized by the upper shell 2 and the flexible key pad 4, the inner waterproof clamping rib 22 is positioned at the periphery of the key hole 21, the flexible key pad 4 is extruded between the inner waterproof clamping rib 22 and the circuit board 5, by the design, when moisture enters from the key hole 21 and cannot flow to other positions from the gap between the upper shell 2 and the flexible key pad 4, the moisture can be blocked in the space surrounded by the inner waterproof clamping rib 22 and blocked at the flexible key pad 4, and the flexible key pad 4 is generally silica gel-like and has the waterproof effect, so the moisture cannot permeate into the circuit board 5 through the flexible key pad 4, so that water entering from the key hole 21 can be prevented from contacting the circuit board 5.

And to the region outside the key hole 21, because there is outer seal ring 6 in the outer lane concatenation department of last casing 2 and lower casing 3, so on the whole, to having outer seal ring 6 to carry on waterproofly in the region outside the key hole 21, to within the key hole 21, rely on the waterproof card muscle 22 in and the flexible key pad 4 between squeeze to realize waterproofly, inboard and outside double-deck protection strengthens the whole waterproof ability of medical hand controller, makes it reach IPX 6's waterproof standard.

In order to make interior waterproof card muscle can protect more button holes 21, in this embodiment go up casing 2 and be equipped with the button district, be equipped with a plurality of button holes 21 in the button district, interior waterproof card muscle 22 is established in the outer lane in button district. Referring to fig. 3, the inner waterproof rib 22 is disposed around the 10 key holes 21, and water flowing into the 10 key holes 21 is blocked by the inner waterproof rib 22.

In order to enable better compression between the flexible keymat 4 and the circuit board 5, the outer circumference of the circuit board 5 is larger than the outer circumference of the flexible keymat 4 in this embodiment. After the design, when the inner waterproof clamping rib 22 extrudes the flexible key pad 4, the flexible key pad 4 is not extruded out of the boundary of the circuit board 5, and the separation phenomenon is prevented.

In order to enhance the sealing performance between the outer rings of the upper shell 2 and the lower shell 3, one of the upper shell 2 and the lower shell 3 is provided with an outer ring groove 23, and the other is provided with an outer ring convex rib 33, and the outer ring convex rib 33 is clamped in the outer ring groove 23. In this embodiment, preferably, the outer ring groove 23 is formed in the upper housing 2, the outer ring rib 33 is formed in the lower housing 3, and when the outer ring rib 33 is clamped in the outer ring groove 23, moisture entering from the side needs to cross the outer ring rib 33 and the outer ring groove 23, so that obviously, the entering channel is not smooth, and the waterproof effect is improved.

Preferably, the outer sealing ring 6 is arranged in the outer ring groove 23, so that the outer sealing ring 6 can be well positioned and has small displacement. Of course, the outer sealing ring 6 may be disposed inside the outer ring rib 33. As shown in fig. 5, the outer seal ring 6 in the present embodiment is just pressed inside the outer ring bead 33, but may be provided outside the outer ring bead 33 in other embodiments.

In order to increase the display function of the medical hand controller, in this embodiment, the medical hand controller further includes a display screen 7, the display screen 7 is located inside the housing, meanwhile, a display window 24 is disposed on the upper housing 2, and a mirror 25 is disposed on the display window 24. After the display window 24 is arranged, water may enter the display window 24, so in order to increase the waterproof performance at the display window 24, the mirror 25 and the display window 24 are processed by sealing glue.

Because the shell in this embodiment is formed by last casing 2 and lower casing 3 concatenation, after the concatenation go up casing 2 and lower casing 3 between through the fastener connection, the preferred screw of fastener in this embodiment, go up and be equipped with the mounting hole 26 that supplies the fastener to pass on casing 2, and set up behind the mounting hole 26, water also gets into from mounting hole 26 easily, so in order to avoid this kind of condition to take place, in this embodiment the shell still includes panel 1, panel 1 laminating is on last casing 2 and cover mounting hole 26, panel 1 not only can print some key descriptions like this, can also cover mounting hole 26 for water can't get into from mounting hole 26.

In order to better protect the key protrusions 41 on the flexible key pad 4, the medical hand controller further comprises a key cap 8 in the embodiment, the key cap 8 comprises a circle of brim arranged at the bottom, the key cap 8 is not pressed down, and the brim is attached to the bottom surface of the upper shell 2. Under the condition of not pressing, the key cap 8 is jointed with the bottom surface of the upper shell 2 under the elastic support of the key bulge 41, so that the probability of water entering the key hole 21 is reduced to a certain extent.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
