DETAILED DESCRIPTION

[0029] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0030] See also Figures 1 to 4 The present invention provides an anesthesia dosage adjustment device, including a base 100, a support plate 200, an anesthesia tank 300, a dilution tank 400, a drive connection mechanism 500 and a configuration tank 600.

[0031] Specifically, the support plate 200 is disposed above the base 100 through the elastic support member 110. The support plate 200 can be a bed plate or a seat plate.

[0032] The anesthesia bottle 300 is provided with a first piston, which separates the anesthesia bottle 300 along its axis into a first cavity and a second cavity which are not connected to each other. The second cavity stores the anesthetic agent. The first piston is provided with a first push rod, which passes through one side of the first cavity. The anesthesia bottle 300 is provided with an anesthetic agent outlet connected to the second cavity.

[0033] A second piston is provided in the dilution tank 400, and the second piston separates the anesthetic cannula 300 along its axial direction into a third chamber and a fourth chamber that are not connected to each other. The fourth chamber stores a diluent, and a second push rod is provided on the second piston. The second push rod passes through one side of the third chamber. The dilution tank 400 is provided with a diluent outlet connected to the fourth chamber.

[0034] The driving connection mechanism 500 connects the support plate 200 with the first push rod and the second push rod. When the support plate 200 moves up and down, it can drive the first push rod and the second push rod to move simultaneously along the axis direction of the anesthesia tank 300 and the dilution tank 400. The configuration tank 600 is connected with the diluent outlet and the anesthetic original agent outlet through the connecting pipe, and the configuration tank 600 is provided with a mixed liquid outlet.

[0035] During use, when the patient is located on the support plate 200, the support plate 200 will be pressed down, thereby driving the first push rod and the second push rod to move through the driving connection mechanism 500, and the anesthetic raw material and the preparation liquid can be squeezed into the preparation tank 600, and mixed into the anesthetic liquid of the required measurement and concentration in the preparation tank 600.

[0036] With this device, during the configuration process, there is no need to recalculate and separately sample according to the patient's weight. The device can automatically and accurately prepare anesthetic solutions that are suitable for different patients, while reducing the workload of medical staff.

[0037] In this embodiment, the elastic support member 110 includes a support rod 111 and an elastic member 112. A plurality of mounting holes are provided at intervals on the base 100. The support rods 111 are provided on the support plate 200 in a one-to-one correspondence with the mounting holes and can be slidably inserted into the mounting holes. An elastic member 112 is provided in each mounting hole, and the elastic member 112 is supported on the support rod 111.

[0038] In this embodiment, the anesthesia bottle 300 and the dilution tank 400 are arranged vertically. The drive connection mechanism 500 includes a first pressing plate 510 and a second pressing plate 520. The first pressing plate 510 and the second pressing plate 520 are both arranged on the support plate 200 and are connected to the first push rod and the second push rod, respectively. By arranging the anesthesia bottle 300 and the dilution tank 400 vertically, the structure of the drive connection mechanism 500 can be reduced, and it is convenient for the drive connection mechanism 500 to drive the first push rod and the second push rod to move.

[0039] As a preferred embodiment, the device further comprises a distance adjusting member 700, which is connected to the first pressing plate 510 and the first push rod and is used to adjust the distance of the up and down movement of the first push rod.

[0040] By changing the distance that the first push rod pushes, the amount of diluent entering the configuration tank 600 can be changed while the original anesthetic dose remains unchanged, thereby changing the concentration of the anesthetic solution.

[0041] Specifically, the distance adjusting member 700 includes a first rack 710, a second gear 720, a driving disk 730, a connecting member 740 and a connecting rod 750. The second gear 720 is rotatably arranged on the top of the dilution tank 400. The driving disk 730 is coaxially fixedly arranged with the first rack 710. The first rack 710 is arranged on the first pressing plate 510, and is arranged parallel to the first push rod, and is meshed with the second gear 720. The connecting member 740 is movably connected to the driving disk 730. The two ends of the connecting rod 750 are respectively connected to the connecting member 740 and the top of the first push rod. When the driving disk 730 rotates, the first push rod can be driven to move up and down through the connecting rod 750.

[0042] When in use, the connector 740 is installed on the driving disk 730 according to the required concentration. When the driving disk 730 rotates, the first push rod can be driven to move up and down through the connecting rod 750, and the distance of the up and down movement of the connector 740 is the distance of the up and down movement of the first push rod. When the connector 740 is located near the center of the driving disk 730, when the support plate 200 drops the same distance, the distance of the up and down movement of the connector 740 is shorter, and the configuration pot 600 is pressed less at a single time. On the contrary, when the connector 740 is located near the edge of the driving disk 730, the distance of the up and down movement of the connector 740 is longer, and the configuration pot 600 is pressed more at a single time, thereby achieving the purpose of changing the concentration of the anesthetic solution.

[0043] Specifically, a slide groove is provided on the driving disk 730 along its radial direction. The connecting member 740 includes a slider 741 and a locking member 742. The slider 741 is clamped in the slide groove and can slide along the slide groove, the end of the connecting rod 750 is hinged to the slider 741, and the locking member 742 is provided on the slider 741 for locking the slider 741 on the driving disk 730.

[0044] When in use, the locking member 742 is loosened and the connecting block is slid along the slide groove.

[0045] As another preferred embodiment, the stirring mechanism 800 includes a second rack 810, a second gear 720, a rotating shaft 830 and a stirring rod. The second rack 810 is vertically disposed on the support plate 200, and the second gear 720 is rotatably disposed on the base 100 and meshes with the second rack 810. The rotating shaft 830 is coaxially disposed with the second gear 720 and rotatably extends into the configuration tank 600. There are multiple stirring rods, and the multiple stirring rods are circumferentially spaced and disposed on the outer wall of the rotating shaft 830 located in the configuration tank.

[0046] When the support plate 200 moves up and down, the second rack 810 and the second gear 720 can drive the rotating shaft 830 to rotate, thereby driving the stirring rod to stir and improve the uniformity of the anesthetic solution.

[0047] In addition, in a specific implementation, the device may further include an anesthesia supplement tank and a dilution supplement tank, which are respectively connected to the second chamber and the fourth chamber through a connecting pipe, and a one-way valve that can only communicate in the direction of the second chamber and the fourth chamber is provided on the connecting pipe. Through the anesthesia supplement tank and the dilution supplement tank, during the movement of the first piston and the second piston toward the first chamber and the third chamber, liquid can be added to the second chamber and the fourth chamber, which is necessary for the next patient to use.

[0048] The use of the above-mentioned anesthesia dosage adjustment device:

[0049] During use, when the patient is located on the support plate 200, the support plate 200 will be pressed down, thereby driving the first push rod and the second push rod to move through the driving connection mechanism 500, and the anesthetic raw material and the preparation liquid can be squeezed into the preparation tank 600, and mixed in the preparation tank 600 to form an anesthetic liquid with the required measurement and concentration.

[0050] With this device, during the configuration process, there is no need to recalculate and separately sample according to the patient's weight. The device can automatically and accurately prepare anesthetic solutions that meet the different characteristics of different patients, while reducing the workload of medical staff.
