[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0031] Depend on Figure 1 , Figure 2 and Figure 3As shown, an infusion pump flow detection device includes an infusion pump host 1, an opening and closing component 2, an infusion board 3 and an infusion tube 4. The opening and closing component 2 is rotatably installed at the side opening of the infusion pump host 1, the infusion board 3 is fixedly installed inside the infusion pump host 1, the infusion board 3 is provided with an infusion tube 4, a counting mechanism 5 is fixedly installed on one side of the infusion board 3, the counting mechanism 5 includes a moving groove 51, a moving groove 51 is opened on one side of the infusion board 3, a counting block 53 is slidably installed inside the moving groove 51, and a pushing mechanism 6 is provided inside the infusion board 3. The mechanism 6 is squeezed and extruded with the inner wall of the delivery tube 4, so that the infusion tube 4 for delivering the drug solution can be installed inside the infusion plate 3. Through the operation of the internal components of the infusion pump host 1 and the pushing mechanism 6, the drug solution inside the infusion tube 4 is squeezed to achieve peristaltic pushing of the drug solution. When the pushing mechanism 6 is working, it will automatically push the counting block 53, and the moving plate 52 will move stably left and right inside the moving groove 51. Every time the moving plate 52 moves, it will trigger the counting mechanism 5 components to work, so that the total amount of drug solution delivered can be accurately calculated to achieve the purpose of flow monitoring.

[0032] By the attached Figure 3 As shown, in this embodiment, the counting mechanism 5 also includes a moving plate 52, a touch component 54, a counting module 55 and a reset component 56. The moving plate 52 is slidably installed inside the moving groove 51, and the moving plate 52 is fixedly connected to the end of the counting block 53. The touch component 54 is fixedly installed on the side of the moving plate 52, and the counting module 55 is arranged on one side inside the infusion plate 3. The reset component 56 is symmetrically fixedly installed inside the moving groove 51, and the reset component 56 is slidably connected to the moving plate 52. When the counting block 53 is squeezed during use, the moving plate 52 will move synchronously with the moving plate 52, so that the touch component 54 automatically performs the counting operation. With the cooperation of the reset component 56, the number of times the touch component 54 is touched is accurately calculated. The existence of the counting module 55 can automatically move to the opening part of the moving groove 51 when the counting block 53 is not squeezed, so as to realize the rapid reset of the counting block 53, which is convenient for subsequent multiple and cyclic use.

[0033] By the attached Figure 4As shown, in this embodiment, the touch assembly 54 also includes a touch rod 541, a touch block 542 and a touch switch 543. The touch assembly 54 is fixedly installed on the side of the movable plate 52, the touch block 542 is fixedly installed on the end of the touch rod 541, and the touch switch 543 is fixedly installed on one side of the inner wall of the movable groove 51. The touch block 542 is squeezed and contacted with the top touch end of the touch switch 543. When the counting block 53 moves during use, the touch rod 541 will push the touch block 542 to move to the side close to the touch switch 543. When the touch block 542 moves to the target position, the movable plate 52 will touch the touch switch 543 to connect the internal circuit of the touch switch 543. At this time, the reset assembly 56 will automatically calculate the number of times the touch switch 543 is touched, and complete the calculation of the total number of reciprocating times of the counting block 53.

[0034] By the attached Figure 4 As shown, in the present embodiment, the reset assembly 56 further comprises a sliding rod 561, a sliding groove 562 and a spring 563. The sliding rod 561 is fixedly mounted inside the sliding rod 561. The sliding groove 562 is symmetrically provided inside the movable plate 52. The sliding rod 561 is slidably connected to the sliding groove 562. The outside of the sliding rod 561 is provided with a spring 563 on the side of the movable plate 52. When the counting block 53 is close to the side opening of the movable groove 51, the spring 563 is in a relaxed state. During use, the existence of the sliding rod 561 allows the counting block 53 to slide along the outside of the sliding rod 561 through the sliding groove 562 at all times, thereby ensuring the stability of the counting block 53 when moving. The existence of the spring 563 can always keep the position of the movable plate 52 squeezed, so that the movable plate 52 is tightly attached to the side opening of the movable groove 51, thereby facilitating the subsequent recycling of the counting block 53.

[0035] By the attached Figure 5 As shown, in this embodiment, the pushing mechanism 6 includes a driving component 61, a turntable 62, a pushing block 63 and a pushing groove 64. The driving component 61 is arranged inside the infusion plate 3, the turntable 62 is fixedly installed outside the driving component 61, and the pushing block 63 is symmetrically fixedly installed on the outer wall of the turntable 62. A pushing groove 64 is provided inside the infusion plate 3 outside the turntable 62. The top of the pushing block 63 is squeezed and contacted with the outer wall of the infusion tube 4. During use, the pipeline for conveying the liquid medicine is installed inside the infusion plate 3, and then the driving component 61 is driven to provide power for the rotation of the turntable 62. When the turntable 62 rotates, the two groups of pushing blocks 63 will be squeezed and contacted with the outer wall of the infusion tube 4 in turn. The squeezed part of the infusion tube 4 will form a negative pressure area, which will automatically absorb other liquid medicine inside the infusion tube 4, and then when the pushing block 63 moves close to the outer wall of the infusion tube 4, the liquid medicine inside the infusion tube 4 will be pushed.

[0036] By the attached Figure 6As shown, in this embodiment, the driving assembly 61 also includes a driving motor 611 and a conveying shaft 612. The driving motor 611 is fixedly installed inside the infusion plate 3, and the conveying shaft 612 is fixedly installed at the output end of the driving motor 611. The conveying shaft 612 is fixedly connected to the turntable 62. When in use, the driving motor 611 drives the conveying shaft 612 to rotate, providing power for the rotation of the turntable 62 on the side, and the turntable 62 automatically rotates instead of the pushing block 63.

[0037] By the attached Figure 7 As shown, in this embodiment, the infusion plate 3 also includes a bottom plate 31, a mounting groove 32, a blocking block 33, a bubble detector 34 and a liquid stopping clamp 35. The bottom plate 31 is fixedly installed on the side surface of the infusion pump host 1, and a mounting groove 32 is opened inside the bottom plate 31. The blocking block 33 is symmetrically fixedly installed at the top opening of the mounting groove 32. The bubble detector 34 is fixedly installed at the top of the bottom plate 31, and the liquid stopping clamp 35 is fixedly installed at the bottom end of the bottom plate 31. During use, the infusion tube 4 is installed inside the mounting groove 32. The use of the blocking block 33 limits the position of the infusion tube 4 itself to prevent the infusion tube 4 from automatically bouncing up when delivering the medicine. The existence of the bubble detector 34 can detect bubbles in the infusion tube 4 when the medicine is delivered to prevent excessive air from being input, which affects the health safety of subsequent patients. The use of the bottom liquid stopping clamp 35 can quickly close the infusion tube 4 as a whole to achieve pipeline closure.

[0038] By the attached Figure 8 As shown, in this embodiment, the opening and closing component 2 also includes an opening and closing plate 21, a connecting port 22, and an extruded rubber layer 23. The opening and closing plate 21 is rotatably installed at the side opening of the infusion pump host 1. The upper and lower ends of the opening and closing plate 21 are provided with connecting ports 22. The inner wall of the opening and closing plate 21 is fixedly installed with an extruded rubber layer 23. During use, the infusion tube 4 can be quickly and stably installed into the infusion plate 3 through the use of the connecting port 22. After the opening and closing plate 21 is closed, the infusion tube 4 can pass through the connecting port 22 to be stably connected to other components. The installation of the extruded rubber layer 23 can extrude the infusion tube 4 inside the infusion plate 3 to ensure the stability of the infusion tube 4 when in use.

[0039] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
