Description

Hand-held medical detector handle

Technical Field

The utility model relates to a handle of a handheld medical detector.

Background

The handheld medical detector is commonly used in the detection of the five sense organs and comprises a handle and a replaceable detection head matched with the handle. The replaceable detecting heads are usually an ophthalmoscope detecting head, an otoscope detecting head, an oral cavity tongue depressor detecting head and the like. The structure of a medical detector handle popular in the market at present comprises a shell, an end cover, a switch, a pen hanger and an adapter interface matched with a replaceable detection head. The dry battery is placed in the casing cavity, and the end cover sets up the afterbody at the casing for change the battery. Because the interior of the end cap needs to be in contact with one of the poles of the cell to make electrical connection, the end cap needs to be made of a conductive material. The pen hanger is arranged at one end close to the adapting interface and is used for being conveniently inserted on the pocket when the handheld medical detector is not used. The switch is arranged on the shell at the position of the pen hanger, and the button of the switch is exposed out of the outer surface of the pen hanger. The occupation space of the pen hanger is reasonably utilized, and the switch is convenient to use. The connecting structure of the electric connecting pole of the switch and the pen hanger is arranged in the gap between the adapting interface and the shell, so that the structure can be reasonably utilized, and meanwhile, the assembly is convenient. The pen hanger is made of metal materials because of a certain structural shape and a certain strength, so that the pen hanger is in contact with the electric connection electrode of the switch contacted with the pen hanger, and meanwhile, the electric connection is realized. And the other electric connection pole of the switch is electrically connected with the end cover. In general, the switch can only control the on-off of the whole circuit, but under certain special conditions with very low probability (for example, a medical detector is placed on a common stainless steel tray or a similar stainless steel platform in a medical place in a certain specific gesture), the end cover and the pen hanger can touch with external conductive materials at the same time, so that the two sides of the switch are short-circuited, the circuit of the handle bypasses the switch to be conducted under the condition that the switch of the handle is disconnected, and the detection head works abnormally in an idle state. Affecting the subsequent normal operation of the medical detector and even damaging the medical detector.

Disclosure of Invention

The utility model aims to overcome the defects in the prior art and provide a handle of a handheld medical detector, which can prevent electric conduction between an end cover and a pen hanger under unexpected conditions.

The utility model comprises a shell, an end cover, a switch, a pen hanger and an adapting interface matched with a replaceable detecting head, wherein the shell is hollow, the end cover is arranged at the tail part of the shell, the pen hanger is arranged at a position close to the adapting interface, a fixed end of the pen hanger is connected with the adapting interface, a free end extends out of the pen hanger towards the tail part of the shell, and the switch is arranged on the shell where the pen hanger is positioned.

Most of the accidents are that the free end of the pen hanger and the end cover are simultaneously contacted with the external conductive material to cause the short circuit at the two sides of the handle switch, and the structure can prevent the free end of the pen hanger from being electrically contacted with the external conductive material, so that the short circuit at the two sides of the handle switch can be effectively prevented.

Drawings

The details of the utility model are further elucidated below in connection with the accompanying drawings and examples.

Fig. 1: the structure of this embodiment is schematically shown.

Fig. 2: the front view of the direction of the pen hanger in the embodiment.

Description of the embodiments

As shown in the figure, this embodiment includes casing 1, end cover 2, switch 4, pen string 3 and the adaptation interface 5 that matches with the replaceable detection head, wherein casing 1 cavity, and the hollow part is used for placing dry cell, and end cover 2 sets up the afterbody at casing 1 for change the dry cell and pass through the negative pole spring with the negative pole of dry cell and realize electric connection simultaneously under operating condition, pen string 3 sets up and is being close to adaptation interface 5 one end, and switch 4 sets up on casing 1 of pen string 3 position, and switch 4's button 44 exposes at pen string 3's surface. The pen hanger 3 is provided with a fixed end 31 and a free end 32, the fixed end 31 of the pen hanger 3 is close to the adapting interface 5, a part of the fixed end 31 extends into a gap between the adapting interface 5 and the shell 1, meanwhile, the switch 4 is provided with an electric connection pole 41 leaning towards the direction of the adapting interface 5, a part of the electric connection pole 41 extends into the gap between the adapting interface 5 and the shell 1, and the extending part of the fixed end 31 of the pen hanger 3 and the extending part of the electric connection pole 41 of the switch 4 are overlapped in the radial direction. The adapter 5 is sleeved on the inner layer of one end of the head of the shell 1, and is provided with a notch corresponding to the positions of the fixed end 31 of the pen hanger 3 and the extending part of the electric connecting electrode 41 of the switch 4, so as to form a gap for accommodating the extending part of the fixed end 31 of the pen hanger 3 and the electric connecting electrode 41 of the switch 4. The free end 32 of the pen hanger 3 faces in the direction of the end cap 2. An opening 33 is provided in the middle of the pen hanger 3, through which opening 33 the button 44 of the switch 4 is exposed. The switch 4 also has a second electrical connection pole oriented in the direction of the end cap 2, which is electrically connected to the end cap 2. In this way, the on-off between the negative electrode of the dry battery and the adapting interface 5 can be controlled by controlling the switch 4, thereby controlling the on-off of the whole handle circuit.

An insulating element 7 is provided on the outer layer of the free end 32 of the pen hanger 3. Because the outer wall of the pen hanger is large in distance from the axis of the shell, the outer wall of the end cover is small in distance from the axis of the shell, the outer wall of the pen hanger is almost parallel to the axis of the shell, and the button of the switch also protrudes above the outer wall of the pen hanger, when the pen hanger and the end cover are simultaneously contacted with an external conductive material, particularly contacted with an external planar conductive material, most of the situations are that the free end of the pen hanger is contacted with the external conductive material. Therefore, the outer layer of the free end of the pen hanger is insulated, so that the short circuit at the two sides of the switch can be effectively prevented.

The pen hanger is made of a metal material because of a certain structural shape and a certain strength, and is made of a stainless steel material in the embodiment. The insulating member is made of an insulating material, and the embodiment is made of a plastic material.

The insulating piece 7 is fixedly connected with the free end 32 of the pen hanger 3. The two can be in a snap connection, a jogged connection, a sleeved connection, an adhesive connection or other permanently or detachably fixedly connected connection structures.

The structure arrangement of the insulating part is arranged on the outer layer of the free end of the pen hanger, so that the pen hanger has little difference compared with the prior art, and can improve and reform the performance with the least investment of cost on the basis of the prior art.

In the utility model, the head of the handle shell refers to the direction that the handle faces one side of the replaceable detecting head, and the tail of the handle shell refers to the direction that the handle faces one side of the replaceable detecting head.
