[0024] Figure 1 is an axonometric diagram of an infusion device for convenient inhalation of liquid medicine in this embodiment. Figure 2 yes Figure 1 Axonometric view after removing the infusion tube. Figure 1 and Figure 2 As shown, the infusion device provided in this embodiment can not only realize the output of the medicine liquid through the setting of the traction device 1 and the piston cutting assembly 2 (that is, after the airbag 6 is removed, the medicine liquid can be output to the outside through the needle tube 5), but also can suck the external medicine liquid into the infusion tube 3 through the setting of the sealing cover 7 and the airbag 6 (that is, open the sealing cover 7, insert the infusion tube 3 into the medicine liquid container, then suck the medicine liquid into the infusion tube 3 through the airbag 6, and then cover the sealing cover 7 tightly). The infusion device designed with this structure can ensure the normal infusion of the infusion tube 3 and conveniently suck the medicine liquid into the infusion tube 3.

[0025] Specifically, the infusion device provided in this embodiment is composed of a bracket 4, a piston cutting assembly 2, an infusion tube 3, a needle tube 5, an airbag 6, a sealing cover 7 and a traction device 1. Preferably, the piston cutting assembly 2 in this embodiment includes a blade 21 mounted on the bracket 4, and a piston assembly fastened to the blade 21. The piston assembly includes a piston rod fastened to the blade 21, and a piston 22 sleeved on the end of the piston rod. The piston 22 is inserted into the infusion tube 3 through the piston rod. Further preferably, the piston assembly is arranged on the side of the blade 21 where the cutting edge 211 is provided, the traction device 1 is arranged adjacent to the piston cutting assembly 2, and the traction device 1 is arranged on the side away from the cutting edge 211 of the blade 21.

[0026] When the traction device 1 is started, the traction device 1 pulls the infusion tube 3 to feed and leads the infusion tube 3 cut by the blade 21 outward, and then the infusion tube 3 is squeezed by the piston 22 to complete the output of the liquid medicine.

[0027] To be more specific, in order to achieve both the outward output of the medicinal liquid in the infusion tube 3 and the satisfaction of sucking the medicinal liquid into the infusion tube 3, as a preference, in this embodiment, a needle tube 5 is inserted on the piston 22, one end of the needle tube 5 is inserted into the piston 22 and connected with the infusion tube 3, and the other end is provided with a detachable air bag 6. In addition, in this embodiment, an adapter 8 is provided at the end of the infusion tube 3 away from the traction device 1, and a sealing cover 7 is provided on the adapter 8.

[0028] With the infusion device of the above-mentioned structural design, after the empty infusion tube 3 is installed, the end of the infusion tube 3 provided with the sealing cover 7 is opened, and then the airbag 6 is installed to the needle tube 5. The airbag 6 is then manually squeezed to suck the medicine into the infusion tube 3. Then the sealing cover 7 is closed tightly, the airbag 6 at one end of the needle tube 5 is removed, and the needle tube 5 is connected to the external infusion needle. Then, the normal output of the medicine can be completed through the traction device 1.

[0029] The infusion device designed in this way can conveniently suck the drug solution into the infusion tube 3, avoiding many troubles caused by the infusion tube 3 carrying the drug solution during installation.

[0030] More specifically, the traction device 1 in this embodiment includes two bearing seats 11 mounted at one end of the bracket 4, an upper traction roller 12 and a lower traction roller 13 mounted along the height direction of the two bearing seats 11, and a motor 14 for driving the upper traction roller 12 and the lower traction roller 13 to rotate. The cut infusion tube 3 is led between the upper traction roller 12 and the lower traction roller 13, and then under the driving action of the motor 14, the infusion tube 3 can be pulled outward through the synchronous rotation of the upper traction roller 12 and the lower traction roller 13, and at the same time, the piston 22 in the piston cutting assembly 2 can continuously squeeze the liquid medicine in the infusion tube 3 and output it outward along the needle tube 5, thereby meeting the infusion demand of the infusion device.

[0031] As a further preference, the same end of the drive shafts of the upper traction roller 12 and the lower traction roller 13 in this embodiment are exposed on the outside of the bearing seat 11, and the two drive shafts are respectively fastened with transmission teeth for mutual engagement. When the motor 14 is actively fastened to the drive shaft of the upper traction roller 12 or the lower traction roller 13 through the coupling, the upper traction roller 12 and the lower traction roller 13 can be driven to work by the rotation of the motor 14.

[0032] Furthermore, in the present embodiment, in order to facilitate the stable and reliable positioning of the infusion tube 3 when cooperating with the piston 22, so that the piston 22 and the infusion tube 3 can cooperate more smoothly, preferably, in the present embodiment, a positioning hole is provided through the bracket wall of the bracket 4. After the infusion tube 3 passes through the positioning hole, it cooperates with the piston 22 on the above-mentioned piston cutting assembly 2. In this way, it is possible to prevent the infusion tube 3 from swinging randomly when cooperating with the piston 22, thereby affecting the normal output of the medicine.

[0033] When using the infusion device with the above-mentioned structural design, the empty infusion tube 3 can be installed first, and then the medicine liquid can be sucked into the infusion tube 3 through the air bag 6. This operation can greatly avoid the many troubles caused by the installation of the infusion tube 3 with medicine, and the required medicine liquid can also be mixed into the infusion tube 3 as needed.

[0034] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
