[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: an anesthesia catheter with adjustable anesthesia flow, including a fixed seat 1, the inner wall of the fixed seat 1 is detachably mounted with a catheter 2, the catheter 2 is a prior art, and is a normal medical anesthesia drainage tube, the upper end of the inner side wall of the fixed seat 1 is provided with a plurality of through holes 5, the bottom end of the inner side wall of the fixed seat 1 is provided with a slide groove 6, the inner wall of the fixed seat 1 is provided with a cavity, and the inner wall of the cavity is provided with an adjustment component 3.

[0032] Reference Figure 3-Figure 4 The adjusting component 3 includes an extrusion block 31, which is slidably connected to the inner wall of the cavity of the fixed seat 1. The interior of the fixed seat 1 is an inclined surface, and the bottom end of the extrusion block 31 is provided with an arc surface. The extrusion block 31 moves on the inclined surface of the fixed seat 1 to squeeze the conduit 2, thereby adjusting the flow of the conduit 2. The slider 32 is slidably connected to the inner wall of the slide groove 6. The outer walls on both sides of the extrusion block 31 are fixedly connected with the sliders 32. The setting of the sliders 32 enables the extrusion block 31 to only move back and forth on the inner wall of the fixed seat 1, thereby squeezing the conduit 2 to different degrees to adjust the flow. The inner wall of the top of the extrusion block 31 is penetrated and slidably connected with a pressing block 33, and the bottom end of the outer wall of the pressing block 33 is fixedly connected with a moving block 35. By pressing the pressing block 33, the moving block 35 can be driven to move downward on the inner wall of the extrusion block 31.

[0033] Reference Figure 3-Figure 4The top of the outer wall of the two groups of connecting blocks 36 is provided with an inclined surface, and the inner side wall of the moving block 35 contacts the inclined surface of the top of the connecting block 36. By descending the moving block 35, the inner side wall thereof contacts the inclined surface of the top of the connecting block 36, thereby squeezing the two groups of moving blocks 35 closer to each other. The inner wall of the extrusion block 31 is slidably connected with the two groups of connecting blocks 36, and the bottom ends of the outer walls of the two groups of connecting blocks 36 are fixedly connected with the clamping block 34, which is plugged into the inner wall of the through hole 5. The plugging between the two fixes the extrusion block 31 at multiple positions of the inner wall of the fixing seat 1, and the moving block 35 It is slidably connected to the inner wall of the extrusion block 31, and the two groups of card blocks 34 are elastically connected by a limit spring 37. By arranging the limit spring 37 between the two groups of card blocks 34, when the top ends of the two groups of connection blocks 36 are no longer squeezed and moved by the moving block 35, the card blocks 34 will be elastically acted upon by the limit spring 37, and the connection blocks 36, the moving blocks 35 and the pressing blocks 33 will be synchronously restored to their initial positions. The card blocks 34 penetrate and are slidably connected to the inner wall of the extrusion block 31, and the bottom end of the outer wall of the extrusion block 31 contacts the top end of the outer wall of the conduit 2, and a positioning assembly 4 is arranged on the inner wall of the fixed seat 1.

[0034] Reference Figure 1 and Figure 2 The positioning assembly 4 includes a block 43, and the bottom end of the block 43 is provided with an arc surface, so that when the catheter 2 enters its inner wall, the block 43 can be automatically moved upward by the arc surface of the block 43, and the block 43 is slidably connected to the inner wall of the fixed seat 1, and the pull rod 41 passes through and is slidably connected to the inner wall of the fixed seat 1. The block 43 is elastically connected to the inner wall of the fixed seat 1 through a return spring 42, one end of the return spring 42 is fixedly connected to the top of the outer wall of the block 43, and the other end of the return spring 42 is fixedly connected to the top of the inner wall of the fixed seat 1. The function of the return spring 42 is to automatically reset the position of the block 43 after it moves, and the top of the outer wall of the block 43 is fixedly connected to the pull rod 41.

[0035] Working principle: When adjusting the flow of the conduit 2, first place the conduit 2 directly into the inner wall of the fixed seat 1. The outer wall of the conduit 2 will squeeze the arc surface of the block 43, thereby squeezing the block 43 to drive the pull rod 41 to move upward on the inner wall of the fixed seat 1, and allow the return spring 42 to be elastically compressed until the conduit 2 completely enters the inner wall of the fixed seat 1. The block 43 will be elastically acted upon by the return spring 42 to restore it to its original position, thereby fixing the conduit 2 inside the fixed seat 1.

[0036] When it is necessary to adjust the anesthetic flow rate inside the catheter 2, the pressing block 33 can be pressed to drive the moving block 35 to move on the inner wall of the extrusion block 31, so that the inner side wall of the moving block 35 squeezes the inclined surface of the top of the two groups of connecting blocks 36, so that the two groups of connecting blocks 36 move toward each other, and drive the two groups of clamping blocks 34 to move synchronously on the inner wall of the extrusion block 31, and allow the limit spring 37 to be elastically compressed. At this time, the extrusion block 31 can be directly moved on the inner wall of the fixed seat 1 to contact the surface of the catheter 2, and as the extrusion block 31 moves downward on the inclined surface of the fixed seat 1, the surface of the catheter 2 is squeezed to reduce the anesthetic flow rate inside the catheter 2, and the pressing block 33 is released after the adjustment is completed. The clamping block 34 will be elastically acted upon by the limiting spring 37, and the connecting block 36, the moving block 35 and the pressing block 33 will be synchronously restored to their initial positions, thereby fixing the extrusion block 31 at the current position of the fixed seat 1.

[0037] After the anesthesia flow of the catheter 2 is adjusted, the stopper 43 can be driven by the pull rod 41 to move upward on the inner wall of the fixing seat 1, so that the catheter 2 can be taken out from the inner wall of the fixing seat 1, so that the fixing seat 1 as a whole can be recycled to avoid unnecessary waste of resources.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
