Detailed Description

The present invention will be further explained with reference to the following examples and drawings.

First embodiment, as shown in fig. 1, a schematic structural diagram of a protecting and fixing device for an invasive artery catheterization of a child includes a fixing cylinder 1, a fixing ring 2 is disposed on an outer side of the fixing cylinder 1, an inflation and deflation air bag 3 is disposed on an inner side of the fixing cylinder, a piezoelectric film (not shown in the figure) covers a surface of the inflation and deflation air bag 3 facing a center of the fixing cylinder 1, and the piezoelectric film is connected to a storage battery through a charging and discharging circuit.

Specifically, when the hand fixing device is used, the hand of a child can be fixed by inserting the hand into the fixing cylinder 1 and then fixing the fixing ring 2 to the seat with a rope. An inflation and deflation air bag 3 capable of inflating and deflating is arranged on the inner side wall surface of the fixed cylinder 1, and the inflation and deflation air bag 3 is provided with an air nozzle (not shown in the figure) which can be communicated with an inflation and deflation pump. The inflation and deflation pump can regularly inflate and deflate the inflation and deflation air bags 3, so that the inflation and deflation air bags 3 are alternately expanded and contracted to extrude and relax the arm, thereby achieving the effect of extrusion massage.

Fill the surface covering of gasbag 3 and have a layer and make piezoelectric film by flexible piezoelectric material, so, not only can not influence the travelling comfort when filling gasbag 3 massage arm, moreover, piezoelectric film can fill when the gasbag 3 inflation of filling, along with filling gasbag 3 extrusion arm. Under the piezoelectric effect, the piezoelectric film can generate electric energy, and the storage battery is charged through a charging and discharging circuit. The storage battery can reversely supply power to the piezoelectric film through the charging and discharging circuit, so that the piezoelectric film generates vibration, and the arm is extruded and massaged by the charging and discharging air bag 3 in a vibration massage mode. And the whole device has simple structure, and is convenient for children to use when sitting on the seat for transfusion.

In this embodiment, preferably, the fixed cylinder 1 includes a supporting plate 4, a right side plate 5 and a left side plate 6, and one side of the right side plate 5 and one side of the left side plate 6 are respectively hinged to two sides of the supporting plate 4. The right side plate 5 and the left side plate 6 can be broken off so as to place arms on the supporting plate 4, and after the arms are placed, the right side plate 5 and the left side plate 6 can be folded to form the fixed cylinder 1 to fix the arms. The inner sides of the supporting plate 4, the right side plate 5 and the left side plate 6 are respectively provided with the independent inflation and deflation air bags 3, and each inflation and deflation air bag 3 can be communicated with an inflation and deflation pump. Therefore, the arm can be placed conveniently, the whole arm surface can be massaged, and blood circulation is promoted.

In order to reinforce the stability of the right and left side panels 5, 6 after being folded, the other sides of the right and left side panels 5, 6 are connected by elastic bands 7 and elastic buckles 8. Elastic bands 7 and elastic buckles 8 may be provided at both ends of the right and left side plates 5 and 6, respectively. In use, the elastic fastener 8 can be unfastened to place the arm on the supporting board 4, and then the elastic fastener 8 can be fastened to close the right side board 5 and the left side board 6. The right side plate 5 can be kept connected with the left side plate 6 through the elastic band 7, so that the right side plate 5 and the left side plate 6 are prevented from being completely separated, and the use is convenient.

Further, semiconductor heating fins 9 are provided on the outer wall surfaces of the pallet 4, the right side plate 5, and the left side plate 6. When the temperature is low, the semiconductor heating sheet 9 can heat the whole temperature of the fixed cylinder 1, thereby promoting blood circulation. When the temperature is high, the temperature of the fixed cylinder 1 can be reduced through the semiconductor heating sheet 9 only by changing the electrode direction of the semiconductor heating sheet 9, so that a large amount of sweating of the arm is avoided, and the use comfort of the device is improved.

In this embodiment, it is preferable that the charge and discharge circuit includes a charge circuit and a discharge circuit, and the charge circuit are connected to the secondary battery via a circuit switching switch. The charging circuit, the circuit change-over switch and the discharging circuit are the same as the existing charging circuit, circuit change-over switch and discharging circuit.

When the charging and discharging air pump works, the storage battery and the charging circuit can be conducted through the circuit changeover switch, so that the storage battery can be charged through the piezoelectric film while the charging and discharging air bag 3 massages the arm. When the inflator pump stops working, the storage battery and the discharge circuit can be conducted through the circuit switch, so that the storage battery can reversely supply power to the piezoelectric film to enable the piezoelectric film to vibrate, and the arm is vibrated and massaged by replacing the extrusion massage mode of the charge-discharge air bag 3. And the circuit change-over switch is a timing change-over switch, and can change over the connection circuit of the storage battery in a timing way, thereby achieving the purpose of alternately changing over the massage modes.

The second embodiment and the second embodiment are substantially the same as the first embodiment, and the main differences are as follows: the circuit change-over switch is a temperature change-over switch.

Because the air filling and discharging bag 3 can form a gap with the arm when being contracted, air can enter the gap to take away the skin temperature and sweat of the human body. Therefore, when the air temperature is high, the mode of squeezing and massaging can avoid the inflatable air bag from being contacted with the skin all the time, and the comfort is optimal. When the temperature is low, the inflatable air bag can be kept in contact with the skin in a vibration massage mode, and heat loss is avoided.

The temperature change-over switch is the same with current temperature change-over switch, can switch over the circuit that the battery switched on according to ambient temperature to switch into with external environment temperature assorted mode with the massage, improve the comfort level of massage.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
