[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0021] Secondly, the term "an 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 phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0022] Example 1
[0023] Please see Figures 1-8 This is the first embodiment of the present invention. This embodiment provides a disposable infusion pump, including: a mounting box 1, a first mounting cover 2, an insertion hole 5, and a diaphragm pump 9. The first mounting cover 2 is disposed on one side of the outer surface of the mounting box 1, the insertion hole 5 is disposed on the other side of the outer surface of the mounting box 1, and the diaphragm pump 9 is disposed inside the mounting box 1. It also includes: The protective cover 3, the mounting component 18, and the fixing component 19 are provided. The protective cover 3 is disposed on one side of the outer surface of the first mounting cover 2, the mounting component 18 is disposed on the top of the diaphragm pump 9, and the fixing component 19 is disposed inside the mounting component 18.
[0024] The mounting component 18 includes a spring retaining ring 181, a return spring 182, a sliding sleeve 183, a first connecting member 184, a mating hole 185, and a limiting ball 186. The first connecting member 184 and the second connecting member 187 are respectively located at the component connection points inside the mounting box 1. The spring retaining ring 181 is disposed on the outside of the first connecting member 184. The return spring 182 and the sliding sleeve 183 are both disposed on the outside of the first connecting member 184. The mating hole 185 is opened inside the first connecting member 184 and communicates with one end. There are multiple limiting balls 186, which are rotatably disposed inside the mating hole 185.
[0025] The fixing member 19 includes a second connector 191, a limiting protrusion 192 and a limiting groove 193. The limiting protrusion 192 is disposed on the outer surface of the second connector 191, and the limiting groove 193 is opened on the outer side of the second connector 191 and located on one side of the limiting protrusion 192.
[0026] The first connector 184 and the second connector 191 are respectively located at the component connection points inside the mounting box 1. The spring plug ring 181 is disposed on the outside of the first connector 184. The return spring 182 and the sliding sleeve 183 are both disposed on the outside of the first connector 184. The mating hole 185 is opened inside the first connector 184 and passes through one end. There are multiple limiting balls 186 that are rotatably disposed inside the mating hole 185. The limiting protrusion 192 is fixedly disposed on the outer surface of the second connector 191. The limiting groove 199 is opened on the outside of the second connector 191 and is located on one side of the limiting protrusion 192.
[0027] Slide the sliding sleeve 183 downwards, keeping it in a downward position, thus freeing it from the pressure on the limiting ball 186. Insert one end of the second connector 191 directly into the mating hole 185 inside the first connector 184. The limiting ball 186 moves outwards under the push of the second connector 191. At the same time, the position of the limiting groove 19 corresponds exactly to the position of the limiting ball 186, so that the insertion of the second connector 191 is completely locked into the interior of the first connector 184.
[0028] The protective cover 3 includes a connecting block 31, a protective plate 32, four embedded posts 33, a locking hole 34, a transparent plate 35, and a groove 36. The protective plate 32 is disposed in the middle of one side of the connecting block 31. The four embedded posts 33 are respectively disposed around the outer surface of the connecting block 31. The two locking holes 34 are respectively opened on both sides of the outer surface of the embedded posts 33. The transparent plate 35 is disposed in the middle of one side of the protective plate 32. The two grooves 36 are respectively opened on both sides of the outer surface of the protective plate 32.
[0029] The groove 36 makes it easy for users to grip the connecting block 31 with their fingers, and the transparent plate 35 is made of transparent plastic.
[0030] The inner walls of the socket 5 are provided with storage slots 6 on both sides. The storage slots 6 are provided with clips 7. Four sockets 5 are respectively opened around the rear side of the mounting box 1, and another four sockets 5 are respectively opened around the front side of the first mounting cover 2.
[0031] For example, the card 7 includes an embedded protrusion and a spring. The embedded protrusion is hemispherical in shape, and the two ends of the spring are respectively connected to the receiving groove 6 and the embedded protrusion.
[0032] For example, the diameter of the embedded post 33 is adapted to the diameter of the insertion hole 5, and the locking hole 34 is in the shape of a hemispherical groove, and the diameter of the locking hole 34 is adapted to the diameter of the embedded protrusion.
[0033] Example 2
[0034] Please see Figure 1 - Figure 8 This is the second embodiment of the present invention. For example, a diaphragm pump 9 is fixedly installed in the middle inside the mounting box 1. Furthermore, the flow controller 10 is connected to the diaphragm pump 9 through a pipe, the diaphragm pump 9 is connected to the flow sensor 11 through a pipe, the pipe is connected to another pipe through a tee pipe, and extends to the outer surface of the mounting box 1 to connect to the heparin cap 4.
[0035] Furthermore, a battery 8 is provided on one side of the inside of the mounting box 1, a diaphragm pump 9 is fixedly installed in the middle of the inside of the mounting box 1, a flow controller 10 is provided on one side of the top inside of the mounting box 1, and a flow sensor 11 is provided on the other side of the top inside of the mounting box 1.
[0036] Furthermore, the diaphragm pump 9, flow controller 10, and flow sensor 11 are all existing devices. Water flows into the pump from the inlet through the inlet hose, and flows out through the pump outlet to the outlet hose. The outlet hose is connected to a pressure sensor via a tee for pressure feedback. The remaining port of the tee is connected to the tee again via a hose. At this point, there are two remaining ports. One end is connected to the outlet equipped with flow sensor 11 via a hose (which can detect the outlet flow in real time and control the pump to shut down when the outlet is closed). The other end is connected to the inlet of the mechanical flow knob via a hose. One end of the knob outlet is connected to the inlet hose via a hose and a tee. When the knob is opened, the liquid flowing back to the inlet hose increases, and the actual outlet flow decreases. When the knob is opened, the liquid flowing back to the inlet hose decreases, and the actual outlet flow increases.
[0037] In use, the connecting block 31 is embedded into the socket 5 via the embedding post 33. Due to the spring elasticity, the locking piece 7 causes the limiting protrusion to embed into the socket 34, restricting the protective cover 3 to the surface of the first mounting cover 2, thus protecting the digital display screen, control switch, and adjustment keys from damage caused by external impacts during transportation and storage. By holding the groove 36, the connecting block 31 is separated from the surface of the connecting plate, and the locking piece 7 disengages from the socket 34, causing the embedding post 33 to disengage from the socket 5. This allows the connecting block 31 to remove the protective plate 32 from the surface of the connecting plate. Then, the protective cover 3 is fastened to the back of the mounting box 1, and the embedding post 33 is embedded into the socket 5 on the back of the mounting box 1, causing the embedding protrusion of the locking piece 7 to embed into the groove 36. After use, the protective cover 3 is replaced on the front of the mounting box 1 and then discarded. This prevents the digital display screen from being broken and damaged during disposal, thus improving recycling safety.
