In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0025] See also Figures 1 to 4 , the utility model provides a technical solution:

[0026] Embodiment 1, a negative pressure control catheter of a multi-dimensional drug delivery device, comprises: a control box 1 and a protective rubber hose 8.

[0027] Specifically, a control panel 2 is provided on the upper surface of the control box 1. The control panel 2 is a touch screen for the staff to operate and control the device. A control mainboard 3 and an air pump 5 are installed inside the control box 1. Both the control mainboard 3 and the air pump 5 are selected from existing known products.

[0028] Secondly, a monitoring connector 4 is provided on the surface of the control main board 3, and an air pressure sensor is provided in the monitoring connector 4. The MEMS technology is used to process a vacuum cavity and a Wheatstone bridge on a single crystal silicon wafer. The output voltage at both ends of the bridge arm of the Wheatstone bridge is proportional to the applied pressure. After temperature compensation and calibration, it has the characteristics of small size, high precision, fast response speed, and is not affected by temperature changes. Its output mode is generally analog voltage output and digital signal output. The monitoring connector 4 of this device uses a digital signal output mode, which is convenient for connecting with the control main board 3. The vacuum pump 5 is connected to a vacuum hose 6, and a three-way connector 7 is installed in the middle of the vacuum hose 6. One end of the three-way connector 7 is fixed to the monitoring connector 4. The control main board 3 monitors the air pressure in the inner cavity of the vacuum hose 6 through the monitoring connector 4. Figure 3 As shown, when the vacuum pump 5 is working and the vacuum hose 6 is pumping negative pressure, the control mainboard 3 can monitor the air pressure in the inner cavity of the vacuum hose 6 in real time through the monitoring connector 4 and the three-way connector 7;

[0029] Furthermore, a drug delivery device 9 is connected to one end of the protective hose 8. The drug delivery device 9 uses an existing known product and is equipped with a nano-infrared emitter inside for further treatment of the patient's skin. The other end of the protective hose 8 passes through the surface of the control box 1 and extends into the inner cavity of the control box 1. One end of the vacuum hose 6 passes through the protective hose 8 and draws negative pressure to the drug delivery device 9. The vacuum pump 5 draws negative pressure to the inner cavity of the drug delivery device 9 through the vacuum hose 6 to ensure that the drug delivery device 9 can be stably adsorbed on the patient's skin surface.

[0030] In order to control the normal operation of the drug delivery instrument 9, the present application also has a power cord 10 arranged in the inner cavity of the protective hose 8. The power cord 10 is used to control the operation of the drug delivery instrument 9 and the start and stop of the nano-infrared emitter. A power connector 11 is arranged on the surface of the control main board 3. One end of the power cord 10 supplies power to the drug delivery instrument 9, and the other end is connected to the power connector 11. The control main board 3 can control the drug delivery instrument 9 through the power cord 10. When the pressure in the inner cavity of the drug delivery instrument 9 is insufficient, the drug delivery instrument 9 does not work. Only when the drug delivery instrument 9 is tightly fitted to the patient's skin and the vacuum hose 6 draws negative pressure into the inner cavity of the drug delivery instrument 9, the control main board 3 detects through the monitoring connector 4 that the negative pressure in the inner cavity of the vacuum hose 6 is sufficient, the control main board 3 will control the drug delivery instrument 9 to work normally.

[0031] In order to facilitate the staff to observe the working status data of the drug delivery device 9, the present application also has a module power supply 14 for powering the control main board 3 arranged in the inner cavity of the control box 1, and the vacuum pump 5 is also electrically connected to the module power supply 14 and powered by it. The control main board 3 and the module power supply 14 are both fixed to the inner wall of the control box 1 by screws, and the control main board 3 is electrically connected to the control panel 2. After the control main board 3 is connected to the control panel 2, the staff can observe the working data of the drug delivery device 9 through the control panel 2, and control the start and stop of the drug delivery device 9.

[0032] In order to avoid damage to the exhaust hose 6 and the power cord 10, the present application also has a threading tube 13 fixedly penetrating the inner wall of the control box 1, the protective hose 8 is movably connected to the threading tube 13, and the inner wall of the threading tube 13 is provided with a rubber layer, such as Figure 2 and Figure 4 As shown, the threading tube 13 is provided to allow the protective hose 8 to pass through the inner wall of the control box 1 , and the rubber layer can protect the surface of the protective hose 8 , thereby providing good protection for the exhaust hose 6 and the power cord 10 .

[0033] In order to further protect the exhaust hose 6 and the power cord 10, the present application also has a seal 12 provided at the other end opening of the protective hose 8, and the seal 12 is formed by wrapping the exhaust hose 6, the power cord 10 and the protective hose 8 together with electrical tape, such as Figure 4 As shown, after the vacuum hose 6 and the power cord 10 are incorporated into the inner cavity of the protective hose 8, electrical tape is wrapped around the port of the protective hose 8 to fix the vacuum hose 6 and the power cord 10, which can effectively prevent the vacuum hose 6 and the power cord 10 from being pulled and damaged.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
