Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an injection dispersion vibrator, which uses a suction cup-like abutment head that moves in a circular motion so that the drug solution injected subcutaneously or into the muscle spreads into the muscle tissue. It relates to a vibrator that causes massaging.

[Prior art]

Many patients receive injections at hospitals and clinics. In general, when injected subcutaneously or into a muscle (upper arm or buttocks), if the local area is not thoroughly massaged by hand to ensure that the injection solution is dispersed evenly into the muscle tissue, or if the injection is insufficient, the injection This can lead to undesirable reactions such as delayed or diminished effectiveness and even the formation of hard lumps within the muscles, causing prolonged pain. One way to counter this is by having a doctor's assistant or nurse massage the patient in place of the patient. It has become completely unthinkable.

[Problem that the invention attempts to solve]

Therefore, I came up with an electric vibrator used for massaging, but this type of electric massager uses a vibrating part with a pad of soft material such as rubber attached to the tip to apply it to the affected area, or it can be individually shaken with a rubber tip fitted. Although it is suitable for massaging the affected area due to the multiple claw-shaped swinging parts that move, it is not possible to uniformly massage a certain range of the injection site.

[Purpose of invention]

The present invention has been developed in view of the above, and is intended to provide an injection solution dispersion vibrator that can massage the muscles of the injection site so that the injection solution is quickly and uniformly dispersed.

Another object of the present invention is to provide a vibrator that can not only be held and used, but also can be moved up and down along a guide rail, and can be directly applied to injection sites at different heights as required.

The invention also aims to provide a vibrator that can be used for electromassage if desired.

[Means for solving problems]

Based on the above object, the injection solution diffusion vibrator of the present invention rotates a camshaft with a DC motor via a continuously variable transmission whose rotational speed is adjustable.
A vibrator is configured such that a head eccentrically mounted on a camshaft is moved in a circular motion by the rotation of the vibrator, and a pad formed in the shape of a suction cup made of an elastic soft material such as rubber is removably mounted on the head; The pad is characterized in that its surface is removably covered with a thin layer of disinfectant cotton or the like.

The present invention is also characterized in that the vibrator is supported by an upright guide rail so as to be movable up and down, and can be stopped at any position.

Furthermore, instead of the suction cup-like pad, the head is equipped with a pad formed in a block-like abutting portion made of an elastic soft material for use in massage.

[Functions and effects of the invention]

After the vibrator of the present invention having the above configuration is connected to an AC power source via a battery or a rectifier,
When the switch is turned on during use, the camshaft is rotated by the motor, causing the head to perform an eccentric rotational movement, and the pad covered with disinfectant cloth attached to the head of the camshaft is also integrated into the eccentric rotation movement. It begins to move in rotation. After adjusting this movement to an appropriate speed, if the pad is brought into contact with the muscle through a disinfectant towel so that the injection site is located approximately in the center, the eccentric rotational movement of the pad will massage the muscle.

Furthermore, if the vibrator is attached to a guide rail installed along an upright wall or furniture so that it can slide freely and stop at any position, the injection site can be adjusted to the required height depending on the upper arm or buttocks, or standing or sitting posture. By sliding and stopping the device along the guide rail, it is possible to rub the device while standing or sitting.

In the above-mentioned use, by wearing the pad formed in the shape of a suction cup, its suppleness allows it to contact the muscles around the injection site evenly and softly, and in this state, the eccentric rotation movement allows the injection to be applied over a wide area. You can rub it to diffuse it.

Furthermore, if the pads are replaced with block-shaped pads, the rotating speed can be increased to massage affected muscles that feel stiff or painful in the same way as a conventional massage device.

〔Example〕

The above-mentioned and other objects, features, and advantages will be explained below with reference to the illustrations of the embodiment. In FIGS. It has a built-in continuously variable transmission that can freely adjust direction and speed, and the output shaft 11 is exposed from one end (usually 20~
180RPM shifting range). The camshaft 20 has a center portion on one end side connected to the output shaft 11 by screwing through a connecting hole (not shown in the diagram), and an eccentric pin 24 integrally protruding from an eccentric position on the other end side.

The eccentric rotating head 30 has a hollow cylindrical lower end 31 and is rotatably fitted onto the eccentric pin 24 from above through a ball bearing 32 on the circumferential surface and a steel ball 38 on the end surface. Both ends of the ring 32 are engaged with each other by snap rings 27, 37 to prevent them from coming off, and a plurality of ring-shaped grooves 35, 35, . . . are formed along the outer peripheral surface of the cylindrical upper end 36.

The upper end portion 36 of the eccentric rotating head 30 is made of an elastic soft material such as rubber and has a suction cup-shaped abutment portion 43 with a shallowly concave center, and the lower portion integrally connected to the suction cup-shaped abutment portion 43 is made of an elastic soft material such as rubber. In addition to forming the joint portion 41, the inner peripheral surface is provided with the above-mentioned grooves 35, 35...
A pad 40 formed with a plurality of ring-shaped protrusions 45, 45... corresponding to each other is fitted so that the protrusions 45, 45... are engaged with the grooves 35, 35... I'm letting you do it. Note that a plurality of locking protrusions 44 are formed at equal intervals on the circumference of the outer peripheral edge of the corresponding contact portion 43.

The suction cup-shaped abutment part 43 of the pad 40 is further covered with a covering layer 50 of disinfectant cotton or gauze spread in a sheet shape over the entire surface of the recessed part above, and the covering layer 50 is thread loop 51 in the section,
51... are formed, and the loops 51, 51...
... are hooked onto the locking protrusions 44, 44... of the pad 40 and locked.

As shown in FIG. 3, in the vibrator having the above configuration, the housing 10 is slidably held between a pair of guide rails 60, 60 installed upright in parallel along the wall surface. It can be stopped at any position by a brake piece biased by a known spring interposed in the sliding portion of the housing. In this case, a rectifier is installed at one end of the guide rail 60.
A control device 61 such as an output control device is provided and connected to the vibrator housing 10 by an elastic cord, etc., and a motor control switch sensor 62 is provided in the housing 10 (or pad 40) to detect contact of the pad 40. The motor operation may be controlled, or the control operation of the control device 61 may be remotely controlled by a switch box 63 as shown at 63 in the figure.

When the configuration of the above embodiment is used, the camshaft 20 rotates through the output shaft 11 due to the rotational drive of the motor, and the eccentric pin 24 rotates eccentrically.
The eccentric rotary head 30, which is pivotally mounted on the shaft, is also caused to move along a circular orbit. The head 30
The pad 40, in which the cylindrical fitting part 41 is fitted almost integrally, is simultaneously moved along a circular orbit, and the muscle part, etc., which is applied through the disinfectant cotton layer 50, is uniformly rubbed by the circular movement. You will need to knead it gently.

Furthermore, by holding the vibrator on a wall or the like using the guide rail 60, the vibrator can be fully automated by an automatic control device without being held in the hand, and can be applied to health centers and hospitals.
