Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] The following will combine Figures 1-3 A portable high-pressure injector according to an embodiment of the present invention will be described in detail.

[0020] Example:

[0021] This utility model provides a portable high-pressure injector, which is described in reference to... Figures 1 to 3 As shown, the device includes a movable base 1, a support column 2 mounted on the movable base 1, a connecting seat 3 mounted on the top of the support column 2, a connecting rod 4 rotatably mounted on the connecting seat 3, a locking bolt 13 threadedly connected to the connecting seat 3, and a high-pressure injector body 5 detachably mounted on the connecting rod 4. In the above structure, the movable base 1, the support column 2, and the high-pressure injector body 5 constitute a medical high-pressure injection device. The high-pressure injector body 5 is used to inject liquid medication, while the movable base 1 and the support column 2 form a support frame mechanism for the high-pressure injection device, which supports and fixes the high-pressure injector body 5. During use, the rotating connecting rod 4 can adjust the up and down operating angle of the high-pressure injector body 5, and the position of the connecting rod 4 is locked by the locking bolt 13, thereby locking the angle and facilitating the use of the device.

[0022] It should be noted that the high-pressure injector body 5 mentioned above is an existing publicly disclosed device. For its specific structure, please refer to patent CN207384558U or other disclosed structures. Furthermore, this application does not improve the internal structure of the high-pressure injector body 5, so it will not be described in detail here.

[0023] refer to Figures 1 to 3 As shown, the support column 2 includes vertical tube 6, vertical tube 7, and vertical tube 8. Vertical tubes 6, 7, and 8 can be retracted and plugged together. Vertical tubes 6, 7, and 8 can be fixed together by bolts. The movable base 1 is fixedly installed at the bottom of vertical tube 6, and the connecting seat 3 is fixedly installed at the top of vertical tube 8. When the high-pressure injection equipment needs to be carried, the personnel can retract vertical tube 7 into vertical tube 8, and then retract vertical tube 8 into vertical tube 2. Then, the bolts are used to limit vertical tubes 6, 7, and 8 together, which can effectively reduce the height of the high-pressure injection equipment, making it convenient to carry and use as a whole and improving portability.

[0024] When needed, personnel first pull out vertical tube 2 7 and vertical tube 3 8 respectively, and then fix the position between vertical tube 1, vertical tube 2 7 and vertical tube 3 8 with bolts. Then the high-pressure injector body 5 can be supported and fixed for use.

[0025] refer to Figures 1 to 3 As shown, the movable base 1 includes a cross support 9 and four casters 10. The casters 10 are located at the bottom of the cross support 9, and the vertical tube 6 is installed on the cross support 9. This structure, with the cross support 9 and the casters 10, facilitates the movement of the high-pressure injection equipment.

[0026] refer to Figures 1 to 3As shown, the length of vertical tube 6 is slightly longer than that of vertical tube 7, and the length of vertical tube 8 is slightly longer than that of vertical tube 7. When the vertical tubes are folded together, vertical tube 7 is slightly higher than vertical tube 6, and vertical tube 8 is slightly higher than vertical tube 7, which makes it convenient to pull out vertical tube 7 and vertical tube 8 in later use.

[0027] refer to Figures 1 to 3 As shown, the outer diameter of vertical tube 2 7 is adapted to the inner diameter of vertical tube 1 6, and the outer diameter of vertical tube 3 8 is adapted to the inner diameter of vertical tube 2 7. This structure allows vertical tube 1 6, vertical tube 2 7 and vertical tube 3 8 to be connected in an adaptable manner.

[0028] refer to Figures 1 to 3 As shown, limit holes 11 are provided on the upper and lower sides of vertical tube 6, vertical tube 7, and vertical tube 8. Limit bolts 12 can be inserted through the limit holes 11 on vertical tube 6, vertical tube 7, and vertical tube 8. In this structure, when vertical tube 7 and vertical tube 8 are extended, limit bolts 12 can be inserted into the limit holes 11 at the upper part of vertical tube 6 and the lower part of vertical tube 7 to lock the position of vertical tube 6 and vertical tube 7. Similarly, limit bolts 12 can be inserted into the limit holes 11 at the lower part of vertical tube 8 and the upper part of vertical tube 2 to lock the position of vertical tube 7 and vertical tube 8, thus ensuring the extended use state.

[0029] When the device is retracted, after vertical tube 1 (6), vertical tube 2 (7), and vertical tube 3 (8) are retracted into place, personnel can insert bolts through the limiting holes 11 on the upper part of vertical tube 1 (6), vertical tube 2 (7), and vertical tube 3 (8) to lock the position of vertical tube 2 (7) and vertical tube 3 (8) and maintain the retracted state.

[0030] The implementation principle of a portable high-pressure injector according to an embodiment of this application is as follows: When it is necessary to carry the high-pressure injection device, the personnel can retract the second vertical tube 7 into the third vertical tube 8, and then retract the third vertical tube 8 into the second vertical tube 7. Then, the personnel can insert the bolt through the limiting hole 11 at the top of the first vertical tube 6, the second vertical tube 7, and the third vertical tube 8 to lock the position of the second vertical tube 7 and the third vertical tube 8, thereby maintaining the retracted state, reducing the height of the device, and making it convenient to carry.

[0031] When the high-pressure injection equipment is needed, the operator first pulls out the second vertical tube 7 and the third vertical tube 8 respectively. Then, the limiting bolts 12 can be inserted into the limiting holes 11 at the upper part of the first vertical tube 6 and the lower part of the second vertical tube 7 to lock the position of the first vertical tube 6 and the second vertical tube 7. Similarly, the limiting bolts 12 can be inserted into the limiting holes 11 at the lower part of the third vertical tube 8 and the upper part of the second vertical tube 2 to lock the position of the second vertical tube 7 and the third vertical tube 8, thus ensuring that the extended state is in use. Then, the high-pressure injector body 5 can be supported and fixed for use.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
