Background

Ultrasonic detection is a common medical detection mode, and when an ultrasonic wave enters an object and encounters a defect, a part of sound waves generate reflection to feed back detection information, so that a detection effect is achieved. In the use of the ultrasonic detection apparatus, air between the probe of the ultrasonic detection apparatus and the skin of the patient may obstruct the ultrasonic waves from being transmitted into the human body, and in order to obtain a high-quality clear image, a layer of couplant may be coated between the probe and the skin of the patient, so that the probe is connected with the body surface of the patient through the couplant.

The couplant commonly used by medical staff is directly arranged in a couplant bottle, the couplant bottle is made of harder plastic materials and is designed with a sharp-mouth structure at one end, when the couplant bottle is used, the couplant bottle is independently placed aside, the medical staff needs to pick up the couplant bottle when checking, the couplant flows out from the sharp-mouth end through directly extruding the bottle body, so that the couplant is directly sprayed on the body surface of a patient, and then an ultrasonic detection instrument is started to operate; when more places need to be detected or the coupling agent amount is insufficient to be supplemented, medical staff can only operate the coupling agent bottle by one hand to smear the coupling agent because of the problems of medical care, sanitation and the like. However, as the hardness of the couplant bottle is high, and the medical staff needs to consider the operation of the detection instrument when in use, the single hand directly extrudes the couplant bottle, so that the labor is wasted, the extrusion force is difficult to control, and the couplant is easily extruded out in a large quantity, so that the waste is caused; meanwhile, if the residual quantity of the couplant in the couplant bottle is not enough, the couplant is very difficult to extrude, the operation is very inconvenient, and finally, the couplant bottle can only be replaced with a new one, so that the residual quantity is wasted.

Moreover, because the couplant is a flowable liquid, the couplant is frequently taken and moved repeatedly, the couplant is easy to drip, so that the couplant can be remained on an operation interface of an ultrasonic instrument, a couplant bottle and the ground, the couplant is sticky and dirty and is difficult to clean, and the ultrasonic instrument is easy to damage when being cleaned, thereby influencing the detection result, even damaging the instrument and increasing unnecessary medical cost.

2) Parameters are set. The rotary multi-path rotary joint selects the couplant conveying pipe 3 to be used and a detecting instrument probe connected with the couplant conveying pipe 3, so that the couplant conveying pipe 3 is aligned with the discharging hole 11. The temperature in the bottle body 2 is set through the control panel 5, so that the couplant in the bottle body 2 reaches the specified temperature, and the couplant in the couplant bottle is heated, so that discomfort to a patient during smearing is avoided. Meanwhile, according to the graduated scale on the opening and closing door 4 and in combination with the consumption of the basic couplant required by the current ultrasonic detection instrument each time, a single pushing-out value of the couplant is set, so that the pushing distance parameter of the push rod structure 6 is determined, and in the embodiment, the rapid adjustment setting of the addition or the reduction can be carried out according to the actual consumption each time, and the addition of 1-9ml or the reduction of 1-9ml can be set.

3) The control board 9 is started. When detecting, the control board 9 is directly stepped on, so that the push rod structure 6 drives the piston structure 24 to push forward according to the set dosage value parameter, the couplant flows out of the tip end 23 and reaches the couplant conveying pipe 3 through the discharging hole 11, the couplant directly reaches the probe 15 of the ultrasonic detecting instrument through the couplant conveying pipe 3, and when detecting, a medical staff directly presses the control end 14 on the probe 15 by holding the probe 15, so that the couplant is smeared on the body surface of a patient along with the movement of the probe.

4) The amounts were observed. The use condition of the current couplant can be observed in real time through the graduated scale on the opening and closing door 4, and when the couplant in the bottle body 2 is found to be used up, the couplant can be replaced in time.

In this embodiment, the amount of the coupling agent is set by the control panel 5, so that the amount of each pushing can be ensured during pushing, and overflow waste is avoided. Simultaneously through pedal mode control panel 9 start the couplant is extruded to push rod structure 6, avoids still needing to operate the couplant bottle through single hand alone in the operation in-process, when liberating both hands, also makes the couplant release more laborsaving convenient, reduces the extrusion degree of difficulty, lets medical personnel can directly carry out the interpolation of couplant when detecting and scribbles, guarantees to detect continuous uninterrupted. Meanwhile, when the probe is smeared, the smearing amount is further accurately controlled through the touch switch on the control probe 15, so that the smearing position is more accurate, waste is avoided, and meanwhile, if too much couplant is smeared on a patient, the patient is uncomfortable and is difficult to clean after the examination is finished.

Simultaneously, through setting up the cross incision membrane 25 structure in the bottle 2, can guarantee that couplant in the bottle 2 can not leak when not having the extrusion state, avoid the couplant to spill over the health that the drip influences service environment, avoid difficult clear-up state, also avoid the couplant to fall on instrument and equipment simultaneously, cause the damage to the instrument, influence the use of instrument, more avoid the washing to the instrument, reduce the secondary damage to the instrument.

And, through setting up heating structure 12, can carry out heating treatment to the couplant, avoid the couplant to directly paint at the patient body surface, bring the discomfort for the patient, simultaneously through the seal structure setting of casing 1, can stop heating and keep the constant temperature state after the temperature reaches the settlement temperature in casing 1, energy-conserving reaches the heating effect promptly again.

Example two

Unlike the first embodiment, in this embodiment, a power supply device is further disposed in the housing 1, the power supply device is disposed at the discharge hole 11, and the power supply device is communicated with the control panel 5, in this embodiment, the power supply device is a removable and replaceable lithium battery, and the lithium battery provides power for the device, so that the device can be carried for single use, and the application range is wider and more flexible.

Meanwhile, in another embodiment, the propulsion device can be directly powered by the ultrasonic detection instrument, so that the volume of the propulsion device is saved, and the propulsion device can be directly installed on the ultrasonic detection instrument, so that the whole movement and the use are convenient.

The foregoing is merely exemplary of the present utility model, and specific technical solutions and/or features that are well known in the art have not been described in detail herein. It should be noted that, for those skilled in the art, several variations and modifications can be made without departing from the technical solution of the present utility model, and these should also be regarded as the protection scope of the present utility model, which does not affect the effect of the implementation of the present utility model and the practical applicability of the patent. The protection scope of the present utility model is subject to the content of the claims, and the description of the specific embodiments and the like in the specification can be used for explaining the content of the claims.
