Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electrocardiographic telemeter transmitter, and particularly to a completely waterproof electrocardiographic telemeter transmitter that completely prevents water from entering the transmitter.

[Conventional technology]

(1) Background of the invention In general, an electrocardiogram telemeter transmitter is a device that is worn on the body of a heart disease patient and wirelessly transmits the patient's electrocardiogram to a receiver installed in a hospital monitoring room.

By constantly monitoring the patient's electrocardiogram displayed on the receiver, doctors and nurses can immediately take appropriate measures when a change in the patient's condition occurs.

However, since this electrocardiographic telemeter transmitter must be worn on the patient's body 24 hours a day, it is always at risk of water ingress. For example, there are many occasions when water is used in daily life, such as when washing the face, going to the toilet, taking a bath, and swimming, and in such cases, there is a risk that water may enter the electrocardiograph telemeter transmitter. It's easy to think of something.

The present invention relates to a completely waterproof electrocardiographic telemeter transmitter that completely prevents water from entering in such cases.

(2) Conventional Example A conventional electrocardiogram telemeter transmitter had the structure shown in FIG.

In the figure, a top panel 200 is fixed to the top of a case 100 that houses a transmitting circuit board and a battery (not shown) that drives the circuit, and a battery cap 300 is removably attached to the bottom. There is.

A male connector 400, a drive power switch 500, and a call switch 600 are exposed from the top panel 200. When using this electrocardiogram telemeter transmitter, a female connector is connected to the male connector 400. 700 and store the electrocardiogram telemeter transmitter in a pocket or the like.

After doing this, if the electrode (not shown) connected to the tip of the lead cord 800 is brought into close contact with the patient's body surface and the power is turned on, the measured electrocardiogram will be measured using one of the lead cords 800. The antenna is directed toward the receiver in the monitoring room, and the signal is transmitted.

[Problem that the invention attempts to solve]

However, in the conventional example shown in FIG. 9, when the female connector 700 is fitted to the male connector 400, the female connector 700 and the top panel 200 are not in close contact with each other, so water can leak out even from a small gap. invade. This also applies between the battery cap 300 and the case body 100 and between the top panel 200 and the case body 100.

Furthermore, the drive power switch 500 and the call switch 600, which are exposed when the electrocardiogram telemeter transmitter is in use, are not provided with a waterproof structure between them and the top panel 200, allowing water to enter.

On the other hand, the female connector 700 and the male connector 40
0 is the pin receiver 410A, 420
Since there are only A, 430A and pins 410, 420, and 430, the female connector 700 can easily come off when the electrocardiogram telemeter transmitter is used.

That is, conventionally, the waterproof structure of the electrocardiogram telemeter transmitter was incomplete and the connectors were easily disconnected from each other.

The purpose of the present invention is to complete the waterproof structure of an electrocardiogram telemeter transmitter and to prevent the connectors from coming off each other.
