Description

Technical Field

[0001] The present invention relates to the technical field of infusion pumps, and in particular to a intravenous infusion pump. Background Art

[0002] Intravenous infusion pumps can accurately control the speed and volume of infusion. During dehydration treatment, elderly patients have poor tolerance to fluids due to decreased physiological functions, and their heart, kidney and other functions may decline to varying degrees. Using an intravenous infusion pump can ensure that drugs or fluids are delivered at a constant rate, avoiding complications such as increased cardiac load and pulmonary edema caused by too fast infusion, and also avoiding too slow infusion that affects the efficacy of drugs or the effect of correcting dehydration. This precise control helps reduce the risks caused by improper infusion and ensures patient safety.

[0003] Infusion pumps play a key role in large-dose infusion situations, but in actual applications, especially when patients need long-term infusion and may have the need to move (such as going to the bathroom), the design of existing infusion pumps has some limitations. Specifically, due to the lack of a place to directly hang the infusion bag, the infusion pump usually needs to be used in conjunction with an infusion stand. This dependence is particularly inconvenient when the patient needs to move, because the limitations of the infusion stand prevent the infusion pump from moving flexibly over a large range, which means that the patient often needs to be accompanied by others when going to the toilet, which brings a poor experience to the patient. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-Figure 10 As shown, the present invention is an intravenous infusion pump, comprising a pump body 1 and a shell cover 2 installed on the back of the pump body 1, a groove body 3 is arranged on the side of the shell cover 2 away from the pump body 1, a plurality of movably arranged vacuum suction cups 4 are arranged through the bottom of the groove body 3, a negative pressure mechanism 5 corresponding to the vacuum suction cup 4 is installed in the shell cover 2, and a linkage mechanism 6 for controlling the extension and retraction of the vacuum suction cup 4 and sterilizing it is installed on the shell cover 2; the linkage mechanism 6 comprises a toggle member 61, a rotating member 62, an adjusting mechanism 63 and a sterilizing mechanism 64, the toggle member 61 is rotatably arranged in the groove body 3, a rotating hole for the rotating member 62 to rotate is arranged at the center of the bottom of the groove of the groove body 3, the rotating member 62 is rotatably arranged in the shell cover 2 and is coaxially connected with the toggle member 61, the sterilizing mechanism 64 is installed between the toggle member 61 and the rotating member 62, and the rotating member 62 is connected to the negative pressure mechanism 5 through the adjusting mechanism 63.

[0034] It should be noted that when in use, the toggle member 61 is rotated clockwise so that it no longer covers the vacuum suction cup 4. Under the action of the negative pressure mechanism 5, not only will the vacuum suction cup 4 automatically extend into the slot body 3, but multiple vacuum suction cups 4 can also be vacuumed. The adjustment mechanism 63 can be used to limit the vacuum suction cup 4 after it is extended into place, so that the vacuum suction cup 4 can fit closely to the wall or the door panel of the bathroom, and achieve stable adsorption and positioning under the action of vacuum negative pressure. When there is no need to adsorb and position the pump body 1, separation can be achieved by canceling the vacuum adsorption, and the toggle member 61 is rotated counterclockwise to reset. During the resetting process, the adjustment mechanism 63 is used to compress the vacuum suction cup 4 to shrink it into the shell cover 2. In conjunction with the toggle member 61, it is not only convenient to cover and protect the vacuum suction cup 4, but also in the process of counterclockwise rotation, the adsorption surface of the vacuum suction cup 4 can be disinfected and sterilized in conjunction with the disinfection mechanism 64.

[0035] like Figure 3 and Figure 7 As shown, the negative pressure mechanism 5 includes a vacuum generator 51, an annular base 52 and a sealing telescopic member 53. The annular base 52 is installed on the back of the pump body 1, and the annular base 52 is an internal hollow structure. The vacuum generator 51 is installed in the shell cover 2, and the vacuum input end of the vacuum generator 51 is connected to the inner cavity of the annular base 52. One end of the sealing telescopic member 53 is connected to the annular base 52, and the other end is connected to the corresponding vacuum suction cup 4.

[0036] It should be noted that the use of the sealing telescopic part 53 can not only realize sliding telescoping, but also ensure sealing. Starting the vacuum generator 51 facilitates the generation of vacuum inside the annular base 52. The annular base 52 is connected to the vacuum suction cup 4 through the sealing telescopic part 53, thereby facilitating the vacuum suction cup 4 to be vacuumed and achieve positioning adsorption.

[0037] like Figure 1 and Fig. 9 As shown, the toggle member 61 includes an annular cover 611, a square tube 612 and a swivel 614 with an annular groove 613. The swivel 614 is arranged at the center of the slot body 3. A plurality of square tubes 612 are equidistantly distributed along the circumference of the swivel 614. The annular groove 613 is provided on the edge of the swivel 614 close to the slot body 3, and the annular groove 613 is connected to the annular cover 611 through the square tube 612.

[0038] It should be noted that the side of the annular cover 611 close to the bottom of the groove body 3 is an open structure, and the annular cover 611 can cover the vacuum suction cup 4. Multiple square tubes 612 are distributed circumferentially along the rotating ring 614, so that the overall rotation of the toggle member 61 can be achieved by conveniently toggling the square tubes 612.

[0039] like Figure 1 , Figure 2 and Fig. 9 As shown, the groove body 3 includes a rotation groove 31 and an arc surface limiting groove 32. A plurality of arc surface limiting grooves 32 are connected to the rotation groove 31 and are equidistantly distributed along the circumference thereof. The arc surface limiting grooves 32 are used to limit the rotation stroke of the annular cover 611.

[0040] It should be noted that the two ends of the arc-surface limit groove 32 are arc-surface structures that can fit with the curved side walls of the annular cover 611. When the toggle member 61 rotates, it drives the annular cover 611 to move along the trajectory of the arc-surface limit groove 32, driving the square tube 612 and the rotating ring 614 to rotate in the rotating groove 31.

[0041] like Figure 6 and Fig.10 As shown, the rotating member 62 includes a rotating cylinder 621 and an annular plate 622. One end of the rotating cylinder 621 passes through the rotating hole and is coaxially connected to the rotating ring 614, and the end of the rotating cylinder 621 away from the rotating ring 614 is rotatably connected to the back of the pump body 1. The annular plate 622 is installed in the rotating cylinder 621, and the annular plate 622 is flush with the cylinder mouth of the rotating cylinder 621.

[0042] It should be noted that, in order to improve the stability of the drum 621 , the drum 621 is connected to the back of the pump body 1 via a rotary damping shaft so that the drum 621 does not rotate easily. In addition, the annular plate 622 is also fixedly connected to the swivel 614 .

[0043] like Figure 5-Figure 6As shown, the sealing telescopic member 53 includes a cylinder 531, a sliding tube 532, a sealing plug 533, a spring 534 and a positioning block 535. The cylinder 531 is connected and installed on the side of the annular base 52 away from the pump body 1. One end of the sliding tube 532 is connected to the vacuum suction cup 4, and the other end slides through the end of the cylinder 531 and extends to its inner cavity. The sealing plug 533 is sleeved on the outer tube wall of the end of the sliding tube 532 away from the vacuum suction cup 4, and the sealing plug 533 is slidably connected to the cylinder 531. The positioning block 535 is sleeved on the sliding tube 532, the spring 534 is sleeved on the sliding tube 532, and the spring 534 is installed between the positioning block 535 and the cylinder 531.

[0044] It should be noted that the slide tube 532 and the cylinder 531 can slide adaptively, and cooperate with the spring 534 to facilitate the control of the extension and retraction of the vacuum suction cup 4. The use of the sealing plug 533 can not only ensure the sliding sealing, but also will not affect the sliding of the slide tube 532.

[0045] like Figure 2 and Figure 6-Figure 9 As shown, the adjustment mechanism 63 includes an arc plate 631, a support rod 632, an arc extrusion groove 633, a strip plate 634, a pressing pin 635 and a limiting strip 636. The arc plate 631 is movably arranged between two adjacent cylinders 531, and the arc plate 631 is connected to two adjacent positioning blocks 535 through two support rods 632. The arc extrusion groove 633 is arranged on a side of the arc plate 631 away from the annular base 52, and the depth of the arc extrusion groove 633 increases along the toggle member 61. The clockwise rotation direction gradually increases, and multiple strip plates 634 and multiple limit strips 636 are distributed along the circumference of the rotating member 62. When the positioning block 535 is in contact with the inner wall of the shell cover 2, the limit strip 636 is in contact with the side of the positioning block 535 away from the inner wall of the shell cover 2. The pressing pin 635 is installed at the end side wall of the strip plate 634 and extends into the arc-shaped extrusion groove 633. When the toggle member 61 rotates counterclockwise, the pressing pin 635 is used to apply pressure to the bottom of the arc-shaped extrusion groove 633.

[0046] It should be noted that after the toggle member 61 rotates clockwise until it is limited by the arc-surface limiting groove 32, the vacuum suction cup 4 now partially protrudes from the side wall of the shell cover 2 (to facilitate the vacuum suction cup 4 to fit against the wall or bathroom door panel), and the limiting strip 636 fits against the side of the positioning block 535 away from the inner wall of the shell cover 2, so that it will not retract when it contacts the vacuum suction cup 4; when the toggle member 61 rotates counterclockwise, when the annular cover 611 is about to overlap with the vacuum suction cup 4, the vacuum suction cup 4 now only partially extends into the arc-surface limiting groove 32, but the extended part will not hinder the deflection of the annular cover 611, because in this embodiment, a gap is provided between the annular cover 611 and the bottom of the arc-surface limiting groove 32.

[0047] like Figure 9-10As shown, the disinfection mechanism 64 includes a first adsorbent 641, a second adsorbent 642, a third adsorbent 643 and a fourth adsorbent 644 which are connected in sequence. The first adsorbent 641, the second adsorbent 642 and the third adsorbent 643 are respectively installed in the annular cover 611, the square tube 612 and the annular groove 613. A plurality of through holes are circumferentially opened on the annular plate 622 for the fourth adsorbent 644 to pass through. One end of the fourth adsorbent 644 passes through the through hole and extends to the drum 621.

[0048] It should be noted that the first adsorbent 641, the second adsorbent 642, the third adsorbent 643 and the fourth adsorbent 644 can be adsorbent cotton, but are not limited to adsorbent cotton. The area between the annular plate 622 and the bottom of the rotating drum 621 is used to accommodate alcohol for disinfection. The fourth adsorbent 644 is used to automatically adsorb alcohol and transfer it to the third adsorbent 643, and then the second adsorbent 642 transfers it to the first adsorbent 641. The first adsorbent 641 partially extends to the outside of the annular cover 611. When the vacuum suction cup 4 only partially extends into the arc limit groove 32, the protruding part of the first adsorbent 641 can wipe the adsorption surface of the vacuum suction cup 4 when it is deflected.

[0049] like Fig.10 As shown, a liquid inlet 623 for replenishing alcohol into the rotating drum 621 is provided through the center of the annular plate 622 , and a sealing cover 624 located on the inner circle of the rotating ring 614 is threadedly installed at the liquid inlet 623 .

[0050] It should be noted that the sealing cover 624 is loosened to open the liquid inlet 623, and alcohol can be conveniently injected into the cavity of the rotating drum 621 with the aid of a syringe or other tools, so that the alcohol can be replenished as needed.

[0051] like Figure 1-Figure 2 and Figure 4 As shown, a battery 7 is installed on the top of the shell cover 2, and a protective shell 8 covering the battery 7 is installed on the top of the shell cover 2, a storage groove 9 is provided on one side of the pump body 1, and a retractable bracket 10 is rotatably installed in the storage groove 9, a notch groove is opened at the side wall of the telescopic end of the bracket 10, and a hook 11 is provided in the notch groove, and a deflection member 12 for limiting the position of the bracket 10 is rotatably provided on the top of the pump body 1.

[0052] It should be noted that the battery 7 is used to power the pump body 1 after the power cord is unplugged (the battery 7 can be charged when the power cord is powered on), the bracket 10 is rotated to adjust it to the required height, the deflection member 12 is rotated to position the bracket 10, the hook 11 is used to facilitate hanging the infusion bag, and the storage slot 9 is used to facilitate storage of the bracket 10 when it is not in use.

[0053] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
