As shown in fig. 2, the injector with the heating function comprises an injector body 10, a heating jacket 6 is detachably sleeved outside the injector body 10, and a heating mechanism is arranged in the heating jacket 6. As shown in fig. 1, the heating mechanism includes a heating wire 2, and the heating wire 2 of the present embodiment is a conventional spiral heating wire 2. The heating chamber 3 is formed inside the heating jacket 6, and the heating wire 2 is vertically fixed in the heating chamber 3. The quantity of heating wire 2 is four altogether, and every heating wire 2 is equal vertical setting, and four heating wires 2 evenly distributed. The switch 1 is installed on the outer wall of the heating jacket 6, and as can be seen from fig. 3, the switch 1 is electrically connected to the power supply 14, in this embodiment, the power supply 14 only needs to be an existing battery, the battery is installed on the heating jacket, and the four electric heating wires 2 are connected in parallel with the power supply 14 and the switch 1.
As shown in fig. 1, the heating jacket 6 is vertically provided with an observation hole 9 for observing the progress of the liquid medicine in the syringe body 10. Two rotating shafts 4 are symmetrically and rotatably arranged at the top end of the heating sleeve 6 through the axis, and torsion springs are connected between the two rotating shafts 4 and the heating sleeve 6. The two rotating shafts 4 are respectively wound with a lining belt 5, and the lining belts 5 are made of heat-resistant materials such as polyimide materials. The inner wall of the heating sleeve 6 is vertically and slidably connected with a fixing plate 7, the fixing plate 7 is transversely arranged, and the free ends of the two lining belts 5 are respectively connected with the two ends of the fixing plate 7. It can be known from fig. 2 that, the both ends of fixed plate 7 are all slided the cover and are equipped with sliding sleeve 11, all are connected with pressure spring 12 between the tip of two sliding sleeve 11 and fixed plate 7, and when fixed plate 7 slided in heating jacket 6, two pressure springs 12 were compressed, two sliding sleeve 11 and the inner wall sliding connection of heating jacket 6. The specific connection mode is as follows: two vertical sliding grooves are symmetrically formed in the inner wall of the heating sleeve 6 through the axis of the heating sleeve, and the end portions of the two sliding sleeves 11 are connected in the sliding grooves in a sliding mode.
A temperature prompt area is arranged outside the heating sleeve 6, and temperature change ink is coated in the temperature prompt area, and specifically reversible thermosensitive decoloring ink is adopted. The reversible thermosensitive decoloring ink has the original color which disappears after being heated, and can restore the original color after being cooled. The color can be selected from Chinese yellow, golden red, scarlet, rose red, peach red, etc., and any color can be selected in practical application, and different colors can be selected according to different medicines. The temperature of the reversible thermosensitive decoloring ink is 7-13 degrees (refrigerated food), 26-31 degrees (hand feeling), 38-43 degrees, 46-51 degrees and 60-65 degrees, and the reversible thermosensitive decoloring ink with 26-31 degrees is selected in the embodiment and is closer to the temperature of a human body. When the medical staff observes that the color of the temperature change ink almost disappears, the medical staff can know that the heating of the medicine in the injector body 10 is finished.
The specific implementation process is as follows:
initially, the fixing plate 7 is positioned at the top end of the heating jacket 6, and the lining tape 5 is wound on the rotating shaft 4. In actual use, the needle 13 of the syringe body 10 is inserted through the through hole 8 of the fixing plate 7, so that the syringe body 10 abuts against the fixing plate 7. The syringe body 10 is then pushed into the heating jacket 6 until the needle 13 exits the heating jacket 6.
When the injector body 10 moves, the fixing plate 7 can be pushed to the bottom end from the top end of the heating sleeve 6, the lining belt 5 wound on the rotating shaft 4 is pulled out by the fixing plate 7, the rotating shaft 4 rotates, and the force of the torsion spring is accumulated. The backing tape 5 can be padded between the syringe body 10 and the heating jacket 6 after being pulled out, thereby stably connecting the syringe body 10 and the heating jacket 6. If the heating jacket 6 is too small in size, it is inconvenient to insert the injector body 10 into the heating jacket 6; if the heating jacket 6 is oversized, the syringe body 10 is easily inserted, but the syringe body 10 and the heating jacket 6 cannot be stably connected. The gasket 5 is used for being cushioned between the injector body 10 and the heating jacket 6 to facilitate the insertion of the injector body 10 and also to realize the stable connection between the injector body 10 and the heating jacket 6. The backing strip 5 preferably has a thickness and elasticity such that the shape-modified cushion of the backing strip 5 can be used between the syringe body 10 and the heating jacket 6.
When the fixing plate 7 slides in the heating jacket 6, the pressure spring 12 is compressed, and the sliding sleeve 11 is connected with the inner wall of the heating jacket 6 in a sliding manner and cannot extend out. When the needle 13 is pushed out to the lower part of the bottom end of the heating jacket 6, the fixing plate 7 also slides out to the lower part of the bottom end of the heating jacket 6. At this time, the compression spring 12 pushes the sliding sleeve 11 out towards the two ends of the fixing plate 7, the sliding sleeve 11 is transversely supported below the bottom end of the heating sleeve 6, and the contraction force of the compression spring pulls the sliding sleeve 11 towards the inside of the heating sleeve 6, so that the sliding sleeve 11 is tightly abutted against the bottom end of the heating sleeve 6, namely, the fixing plate 7 is positioned in a state shown in fig. 2.
After the injector body 10 is inserted into the heating jacket 6 and the fixing plate 7 is positioned, the medical staff can turn on the switch 1 to heat the liquid medicine in the injector body 10. The switch 1 controls the power supply 14 to be turned on, and the power supply 14 transmits current to the heating wire 2, so that the heating wire 2 generates heat to heat the liquid medicine in the injector body 10. The color of the temperature-change ink gradually disappears in the heating process, and the color of the temperature-change ink coated outside the heating jacket 6 almost completely disappears when the heating temperature reaches 26-31 ℃. When the medical staff observes that the color of the temperature change ink disappears, the medical staff can know that the liquid medicine in the injector body 10 is heated. At this point, switch 1 is closed and the patient is then subjected to normal ear canal irrigation. In the flushing process, medical staff can also observe the propelling condition of the liquid medicine in the syringe body 10 through the observation hole 9 on the heating sleeve 6.
After the completion of the flushing, the syringe body 10 is pulled out of the heating jacket 6, and then the two sliding sleeves 11 are simultaneously pressed to be retracted onto the fixing plate 7, and the fixing plate 7 is slightly pushed back into the heating jacket 6, thereby releasing the fixing plate 7. After the fixing plate 7 is released, the torsion spring drives the rotating shaft 4 to rotate reversely, so that the lining belt 5 is retracted to the rotating shaft 4, and the fixing plate 7 is pulled back to the initial device, thereby realizing the resetting of the device.
The present invention drives the fixing plate 7 to move when the syringe body 10 is inserted into the heating jacket 6, thereby drawing the backing tape 5 between the syringe body 10 and the heating jacket 6, and achieving stable connection of the syringe body 10 and the heating jacket 6. Compared with the prior art that the heating jacket 6 is fixed on the injector by bolts, the operation is more convenient. In addition, the invention also coats temperature change ink on the outer wall of the heating sleeve 6 so that medical staff can observe the heating condition of the liquid medicine.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
