Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, in particular to an automatic bottle opening and medicine mixing device for medical use. Background Art

[0002] In the process of treating patients, it is often necessary to mix reagents packaged in different bottles. In daily injection drug dispensing operations, medical staff need to mix powders or liquid medicines stored in glass medicine bottles or flexible plastic bottles with liquid medicines in drip bottles to achieve the purpose of dispensing treatment.

[0003] When using the drip bottle in the prior art, it is necessary to first insert the needle into the rubber cover of the flexible dosing bottle with great effort, extract the medicine to be mixed from the flexible dosing bottle, and then insert the needle for extracting the medicine into the flexible drip bottle, and perform time-consuming and laborious shaking to mix, which increases the labor burden of medical staff and also causes the problem of incomplete and uneven mixing of the medicine.

[0004] Therefore, the present invention provides a medical automatic bottle opening and medicine mixing device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is: the medical automatic bottle opening and medicine mixing device described in the present invention comprises a support seat; a mixing chamber is installed on the support seat, a piston is slidably connected inside the mixing chamber, one end of the mixing chamber is connected to an air source through an air flow tube, the other end of the mixing chamber is connected to two delivery pipes, and the other end of the delivery pipe is connected to a clamping assembly, and the two clamping assemblies can clamp and fix the bottle mouths of the drip bottle and the dosing bottle respectively, the end of the delivery pipe is slidably connected to a slider that fits with the inner wall, the outer end of the slider is connected to a conical block, and the conical block and the inner end of the slider are connected The outer wall of the conical block is provided with a guide hole connected to the guide groove, and a control valve is installed on the delivery pipe; when the drip bottle in the prior art is used, it is necessary to insert the needle into the rubber cover of the flexible dosing bottle with great effort, and then insert the needle for extracting the medicine into the flexible drip bottle after the medicine to be mixed is drawn out from the flexible dosing bottle, and then the time-consuming and laborious shaking and mixing are performed, which increases the labor burden of medical staff and also has the problem of incomplete and uneven mixing of the medicine; when the medicine mixing device in the present invention is used, the rubber covers in the dosing bottle and the drip bottle are respectively inserted into the two cones, and the mixing bottle is put into the mixing bottle. The tip of the conical block is positioned at the top of the conical block, so that the guide hole of the conical block is located inside the rubber cover, and then the bottle mouths of the dosing bottle and the drip bottle are clamped and fixed respectively by the clamping assembly, and then the mixing chamber is inflated by the air source, so that the piston can press the gas inside the mixing chamber into the delivery tube, and exert pressure on the slider in the delivery tube, so that the slider can drive the conical block to continue to be inserted into the corresponding rubber cover until the guide hole in the conical block completely penetrates the rubber cover and enters the inside of the medicine bottle, so that the delivery tube is connected with the inside of the medicine bottle, thereby completing the automatic opening of the medicine bottle, reducing the labor burden of medical staff, and then the air source is used to open the medicine bottle. The piston is driven to reset inside the mixing chamber, so that the medicine in the two medicine bottles can be drawn into the mixing chamber through the guide groove and the delivery tube for mixing, and the two medicine bottles made of flexible material are convenient for the extraction of the medicine inside them. Then the piston performs multiple reciprocating motions, which can press the mixed medicine into the two medicine bottles and extract them again, so that the medicine can be automatically and efficiently mixed. When the medicines are mixed and drawn into the mixing chamber, the control valve at the medicine adding bottle is controlled to close, and then the piston is controlled by the air source to press the mixed medicine into the drip bottle, thereby completing the automatic proportioning of the medicine. While it is time-consuming and labor-intensive, it also improves the quality of the mixed use of the medicine.

[0007] Preferably, the openings at one end of the two delivery tubes away from the mixing chamber are both arranged vertically upward; by setting the orientation of the delivery tube ports, when the dosing bottle and the drip bottle are installed at the end of the delivery tube, their bottle mouths are both vertically downward, so that when the medicine liquid is extracted under the action of the mixing chamber, the conical block located at the bottle mouth can fully draw the medicine liquid in the two medicine bottles into the mixing chamber, so that the medicine liquid can be mixed more evenly. When the medicine liquid is mixed and concentratedly drawn into the mixing chamber, the conical block can also more fully extract the medicine liquid in the inverted dosing bottle and deliver it to the drip bottle, reducing the situation of insufficient extraction of the medicine liquid in the dosing bottle.

[0008] Preferably, the inside of the delivery tube is rotatably connected with fan blades via a rotating shaft; when the medicine liquid inside the delivery tube flows back and forth under the action of the mixing chamber, it can drive the fan blades to rotate, thereby promoting the mixing of the medicine liquid flowing through the fan blades.

[0009] Preferably, the fan blades corresponding to the dosing bottle are installed at the end of the delivery tube away from the mixing chamber, and the conical block is composed of a movable block at the top and a fixed block at the bottom, a rotating rod is fixedly connected to the guide groove in the movable block, and the bottom end of the rotating rod passes through the guide groove of the fixed block and the slider and is connected to the rotating shaft, and a connecting groove connecting the guide hole and the side wall of the rotating shaft at the bottom end of the slider is opened inside the rotating rod; when the medicine liquid is mixed and the medicine liquid in the dosing bottle needs to be extracted, the medicine liquid in the dosing bottle flows out of the delivery tube at this time, driving the fan blades and the rotating shaft to rotate, so that the rotating shaft can drive the movable block and the guide hole to rotate synchronously through the rotating rod, and the guide hole rotating under negative pressure at this time can more fully inhale the residual medicine liquid in the dosing bottle, further reducing the residual medicine liquid in the dosing bottle.

[0010] Preferably, a magnetic block is connected to the side wall of the rotating shaft at the dosing bottle, and a sliding cavity is connected to the outer wall of the delivery tube corresponding to one side of the rotating shaft, and an adsorption block that can attract the magnetic block is slidably connected inside the sliding cavity, and a spring is connected between the adsorption block and the end of the sliding cavity, and a shaking cavity is provided on one side of the dosing bottle, and a shaking block is slidably connected inside the shaking cavity, and a shaking rod is connected to the outer end of the shaking block, and the inner end of the shaking cavity is connected to the outer end of the sliding cavity through an air pipe; when the medicine liquid in the dosing bottle is completely discharged, the fan blades intermittently attract the adsorption block through the magnetic block on the rotating shaft, so that the adsorption block slides back and forth in the sliding cavity while driving the shaking rod to move back and forth, and reciprocatingly impacts the dosing bottle, thereby promoting the flow and outflow of residual medicine liquid on the dosing bottle.

[0011] Preferably, a push rod is installed on the support seat corresponding to the bottom end of the drip bottle, and the top end of the push rod is connected to an exhaust needle, and an exhaust groove is opened inside the exhaust needle along its axial direction; before the mixed medicine in the mixing chamber is filled into the drip bottle, the exhaust needle is driven by the push rod to penetrate the rubber cover and pierce the inner top end of the drip bottle in advance, and then when the mixed medicine in the mixing chamber is pressed into the drip bottle, the medicine flowing into the drip bottle can press the air at the top end of the medicine bottle out through the exhaust groove of the exhaust needle, thereby reducing the situation in which the medicine in the mixing chamber is difficult to fully press into the interior of the drip bottle due to excessive pressure in the drip bottle.

[0012] Preferably, the bottom end of the exhaust groove is connected to the air pump through a hose; when the piston completely presses the medicine liquid in the mixing chamber into the delivery tube at the drip bottle, the air at the top of the drip bottle is extracted by the operation of the air pump, so that the inside of the drip bottle is in a negative pressure state and the medicine liquid remaining in the delivery tube can be sucked into the inside of the medicine bottle, thereby enabling the medicine liquid to flow into the drip bottle more fully and be used.

[0013] Preferably, the two control valves are respectively installed at the intersection of the delivery pipe and the mixing chamber; by controlling the position of the control valve, after the mixing chamber extracts the mixed medicine, when the control valve at the dosing bottle is closed, the control valve can completely block the delivery pipe at the dosing bottle, thereby reducing the situation where a part of the medicine enters the delivery pipe at the dosing bottle and is difficult to discharge when the piston discharges the medicine, and after the medicine is completely drawn into the drip bottle under the action of the air pump, by closing the control valve at the drip bottle, the situation where the medicine inside the drip bottle flows back from the conical block to the delivery pipe after the air pump stops working is reduced.

[0014] Preferably, a floating ring made of rubber is provided inside the delivery tube at the bottom end of the dosing bottle, and the side wall of the floating ring is in contact with the inner wall of the delivery tube; when the medicine liquid is mixed and the medicine liquid at the dosing bottle is completely extracted, as the liquid level in the delivery tube at the dosing bottle drops, the floating ring will drop synchronously and push down the residual medicine liquid on the inner wall of the delivery tube, so that the mixed medicine liquid can be more fully utilized.

[0015] Preferably, the guide hole at the dosing bottle is set to an arc shape, and when the top end of the guide hole is inserted into the dosing bottle, the bottom end of the guide hole is located in the delivery tube, and a guide sleeve is connected to the inner wall of the delivery tube at the top of the slider; by setting the shape of the guide groove, the contact area between the conical block and the rubber cover is reduced without affecting its normal operation, thereby reducing the resistance when it pierces the rubber cover, and when the medicine liquid flows from the guide hole into between the slider and the rubber cover, the guide sleeve can promote the medicine liquid at this location to flow out of the guide groove in the slider, so that the medicine liquid can be discharged more fully.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention can automatically open the medicine bottle, reducing the labor burden of medical staff. At the same time, the piston is driven by the air source to reciprocate inside the mixing chamber, and the mixed medicine can be pressed into the two medicine bottles and drawn out again, so that the medicine can be automatically and efficiently mixed. After the medicine is mixed and drawn into the mixing chamber, the control valve at the medicine adding bottle is controlled to be closed, and then the piston is controlled by the air source to press the mixed medicine into the drip bottle, thereby completing the automatic proportioning of the medicine. While it is time-consuming and labor-intensive, it also improves the quality of the mixed use of the medicine.

[0018] 2. The present invention reduces the contact area between the conical block and the rubber cover without affecting its normal operation by setting the shape of the guide groove, thereby reducing the resistance when the conical block pierces the rubber cover, and when the medicine liquid flows from the guide hole into between the slider and the rubber cover, the guide sleeve can promote the medicine liquid at this location to flow out of the guide groove in the slider, so that the medicine liquid can be discharged more fully.

Then the piston 3 performs multiple reciprocating motions, which can press the mixed liquid medicine into the two medicine bottles and extract it again, so that the liquid medicine can be automatically and efficiently mixed. After the liquid medicine is mixed and drawn into the mixing chamber 2, the control valve 13 at the dosing bottle 8 is controlled to be closed, and then the piston 3 is controlled by the air source to press the mixed liquid medicine into the drip bottle 7, thereby completing the automatic proportioning of the liquid medicine. While it is time-consuming and labor-intensive, it also improves the quality of the mixed use of the liquid medicine.

[0030] The openings at one end of the two delivery tubes 5 away from the mixing chamber 2 are both arranged vertically upward; by setting the direction of the port of the delivery tube 5, when the dosing bottle 8 and the drip bottle 7 are installed at the end of the delivery tube 5, their bottle mouths are both vertically downward, so that when the medicine liquid is extracted under the action of the mixing chamber 2, the conical block 10 located at the bottle mouth can fully draw the medicine liquid in the two medicine bottles into the mixing chamber 2, so that the medicine liquid can be mixed more evenly. When the medicine liquid is mixed and concentratedly drawn into the mixing chamber 2, the conical block 10 can also more fully extract the medicine liquid in the inverted dosing bottle 8 and deliver it to the drip bottle 7, reducing the situation of insufficient extraction of the medicine liquid in the dosing bottle 8.

[0031] The inside of the delivery pipe 5 is rotatably connected to the fan blades 15 via the rotating shaft 14; when the liquid medicine in the delivery pipe 5 flows back and forth under the action of the mixing chamber 2, it can drive the fan blades 15 to rotate, thereby promoting the mixing of the liquid medicine flowing through the fan blades 15.

[0032] The fan blade 15 corresponding to the dosing bottle 8 is installed at the end of the conveying pipe 5 away from the mixing chamber 2. The conical block 10 is composed of a movable block 16 at the top and a fixed block 17 at the bottom. A rotating rod 18 is fixedly connected to the guide groove 11 in the movable block 16. The bottom end of the rotating rod 18 passes through the guide groove 11 of the fixed block 17 and the slider 9 and is connected to the rotating shaft 14. A connecting groove 19 is provided inside the rotating rod 18 to connect the guide hole 12 and the side wall of the rotating shaft 14 at the bottom of the slider 9; when the liquid medicine is mixed and the liquid medicine in the dosing bottle 8 needs to be extracted, the liquid medicine in the dosing bottle 8 flows out of the conveying pipe 5 at this time, driving the fan blade 15 and the rotating shaft 14 to rotate, so that the rotating shaft 14 can drive the movable block 16 and the guide hole 12 to rotate synchronously through the rotating rod 18. At this time, the guide hole 12 rotating under negative pressure can more fully inhale the residual liquid medicine in the dosing bottle 8, further reducing the residual liquid medicine in the dosing bottle 8.

[0033] A magnetic block 20 is connected to the side wall of the rotating shaft 14 at the dosing bottle 8, and a sliding cavity 21 is connected to the outer wall of the delivery pipe 5 corresponding to one side of the rotating shaft 14, and an adsorption block 22 that can attract the magnetic block 20 is slidably connected inside the sliding cavity 21, and a spring is connected between the adsorption block 22 and the end of the sliding cavity 21, and a shaking cavity 23 is provided on one side of the dosing bottle 8, and a shaking block is slidably connected inside the shaking cavity 23, and a shaking rod 24 is connected to the outer end of the shaking block, and the inner end of the shaking cavity 23 is connected to the outer end of the sliding cavity 21 through an air pipe; when the liquid medicine in the dosing bottle 8 is completely discharged, the fan blade 15 intermittently attracts the adsorption block 22 through the magnetic block 20 on the rotating shaft 14, so that the adsorption block 22 slides back and forth in the sliding cavity 21 while driving the shaking rod 24 to move back and forth, and reciprocatingly impacts the dosing bottle 8, thereby promoting the flow and outflow of the residual liquid medicine on the dosing bottle 8.

[0034] A push rod 25 is installed on the support seat 1 corresponding to the bottom end of the drip bottle 7, and an exhaust needle 26 is connected to the top end of the push rod 25, and an exhaust groove 27 is opened inside the exhaust needle 26 along its axial direction; before the mixed liquid medicine in the mixing chamber 2 is filled into the drip bottle 7, the exhaust needle 26 is driven by the push rod 25 to penetrate the rubber cover and pierce the inner top end of the drip bottle 7. Subsequently, when the mixed liquid medicine in the mixing chamber 2 is pressed into the drip bottle 7, the liquid medicine flowing into the drip bottle 7 can press the air located at the top end of the bottle through the exhaust groove 27 of the exhaust needle 26, thereby reducing the situation in which the liquid medicine in the mixing chamber 2 is difficult to be fully pressed into the interior of the drip bottle due to excessive pressure in the drip bottle 7.

[0035] The bottom end of the exhaust groove 27 is connected to the air pump 28 through a hose; when the piston 3 completely presses the liquid medicine in the mixing chamber 2 into the delivery tube 5 at the drip bottle 7, the air at the top of the drip bottle 7 is extracted by the operation of the air pump 28, so that the inside of the drip bottle 7 is in a negative pressure state and the liquid medicine remaining in the delivery tube 5 can be sucked into the inside of the bottle, so that the liquid medicine can flow into the drip bottle 7 more fully and be used.

[0036] The two control valves 13 are respectively installed at the positions where the delivery pipe 5 and the mixing chamber 2 intersect; by controlling the position of the control valve 13, after the mixing chamber 2 extracts the mixed medicinal liquid, when the control valve 13 at the dosing bottle 8 is closed, the control valve 13 can completely block the delivery pipe 5 at the dosing bottle 8, thereby reducing the situation where a part of the medicinal liquid enters the delivery pipe 5 at the dosing bottle 8 and is difficult to be discharged when the piston 3 discharges the medicinal liquid, and after the medicinal liquid is completely drawn into the interior of the drip bottle 7 under the action of the air pump 28, by closing the control valve 13 at the drip bottle 7, the situation where the medicinal liquid inside the drip bottle 7 flows back from the conical block 10 to the delivery pipe 5 after the air pump 28 stops working is reduced.

[0037] A floating ring 29 made of rubber is provided inside the delivery tube 5 at the bottom end of the dosing bottle 8, and the side wall of the floating ring 29 fits with the inner wall of the delivery tube 5; when the liquid medicine is mixed and the liquid medicine at the dosing bottle 8 is completely extracted, as the liquid medicine level in the delivery tube 5 at the dosing bottle 8 drops, the floating ring 29 will drop synchronously and push down the residual liquid medicine on the inner wall of the delivery tube 5, so that the mixed liquid medicine can be more fully utilized.

[0038] Embodiment 2:

[0039] like Figure 5As shown, compared with Example 1, another embodiment of the present invention is: the guide hole 12 at the dosing bottle 8 is set to an arc shape, and when the top end of the guide hole 12 is inserted into the dosing bottle 8, the bottom end of the guide hole 12 is located in the delivery tube 5, and a guide sleeve 30 is connected to the inner wall of the delivery tube 5 at the top of the slider 9; by setting the shape of the guide groove 11, the contact area between the conical block 10 and the rubber cover is reduced without affecting its normal operation, thereby reducing the resistance when it pierces the rubber cover, and when the medicine liquid flows from the guide hole 12 into between the slider 9 and the rubber cover, the guide sleeve 30 can promote the medicine liquid at this location to flow out from the guide groove 11 in the slider 9, so that the medicine liquid can be discharged more fully.

[0040] Working principle: The rubber covers of the medicine adding bottle 8 and the drip bottle 7 are respectively inserted into the tips of the two conical blocks 10, so that the guide hole 12 of the conical block 10 is located inside the rubber cover, and then the bottle mouths of the medicine adding bottle 8 and the drip bottle 7 are clamped and fixed by the clamping assembly 6, and then the mixing chamber 2 is inflated through the air source, so that the piston 3 can press the gas inside the mixing chamber 2 into the delivery tube 5, and apply pressure to the slider 9 in the delivery tube 5, so that the slider 9 can drive the conical block 10 to continue to be inserted into the corresponding rubber cover until the guide hole 12 in the conical block 10 completely penetrates the rubber cover and enters the inside of the medicine bottle, so that the delivery tube 5 is connected with the inside of the medicine bottle, thereby completing the automatic opening of the medicine bottle, reducing the medical staff's The labor burden of the staff is reduced, and then the piston 3 is driven by the air source to reset inside the mixing chamber 2, so that the liquid medicine in the two medicine bottles can be drawn into the mixing chamber 2 through the guide groove 11 and the delivery pipe 5 for mixing. Then the piston 3 performs multiple reciprocating movements, which can press the mixed medicine into the two medicine bottles and draw it out again, so that the medicine can be automatically and efficiently mixed. When the medicine liquids are mixed and drawn into the mixing chamber 2, the control valve 13 at the medicine adding bottle 8 is controlled to be closed, and then the piston 3 is controlled by the air source to press the mixed medicine liquid into the drip bottle 7 in a concentrated manner, thereby completing the automatic proportioning of the medicine liquid, which is time-consuming and laborious, and also improves the quality of the mixed use of the medicine liquid; by setting the direction of the port of the delivery pipe 5, the medicine adding bottle 8 and the drip bottle 7 are installed in the delivery chamber 2. When the ends of the delivery tube 5 are in a state of being drawn out under the action of the mixing chamber 2, the conical block 10 located at the bottle mouth can fully draw the liquid in the two medicine bottles into the mixing chamber 2, so that the liquid medicine can be mixed more evenly. When the liquid medicine is mixed and concentratedly drawn into the mixing chamber 2, the conical block 10 can also more fully draw out the liquid medicine in the inverted dosing bottle 8 and deliver it to the drip bottle 7, thereby reducing the situation where the liquid medicine in the dosing bottle 8 is not fully extracted; when the liquid medicine in the delivery tube 5 flows back and forth under the action of the mixing chamber 2, it can drive the fan blades 15 to rotate, thereby promoting the mixing of the liquid medicine flowing through the fan blades 15; when the liquid medicine is mixed and needs to be drawn out of the dosing bottle 8, When the liquid medicine in the dosing bottle 8 flows out from the delivery pipe 5, the fan blades 15 and the rotating shaft 14 are driven to rotate, so that the rotating shaft 14 can drive the movable block 16 and the guide hole 12 to rotate synchronously through the rotating rod 18. At this time, the guide hole 12 rotating under the negative pressure state can more fully absorb the residual liquid medicine in the dosing bottle 8, further reducing the residual liquid medicine in the dosing bottle 8; when the liquid medicine in the dosing bottle 8 is completely discharged, the fan blades 15 intermittently attract the adsorption block 22 through the magnetic block 20 on the rotating shaft 14, so that the adsorption block 22 slides back and forth in the sliding cavity 21 while driving the shaking rod 24 to move back and forth, and reciprocatingly impacts the dosing bottle 8, thereby promoting the flow and outflow of the residual liquid medicine on the dosing bottle 8;Before the mixed liquid medicine in the mixing chamber 2 is filled into the drip bottle 7, the exhaust needle 26 is driven by the push rod 25 to penetrate the rubber cover and pierce the inner top of the drip bottle 7. Then, when the mixed liquid medicine in the mixing chamber 2 is pressed into the drip bottle 7, the liquid medicine flowing into the drip bottle 7 can press the air at the top of the bottle out through the exhaust groove 27 of the exhaust needle 26, thereby reducing the situation in which the liquid medicine in the mixing chamber 2 is difficult to be fully pressed into the drip bottle due to excessive pressure in the drip bottle 7. After the delivery tube 5 at the drip bottle 7 is completely pressed into the drip bottle 7, the gas at the top of the drip bottle 7 is extracted by the air pump 28, so that the inside of the drip bottle 7 is in a negative pressure state and the remaining liquid medicine in the delivery tube 5 can be sucked into the inside of the drip bottle, so that the liquid medicine can flow into the drip bottle 7 more fully and be used; by controlling the position of the control valve 13, the mixing chamber 2 extracts the mixed liquid medicine, and when the control valve 13 at the dosing bottle 8 is closed, the control valve 13 can completely drain the delivery tube 5 at the dosing bottle 8 The piston 3 is sealed to reduce the situation that when the medicine liquid is discharged, a part of the medicine liquid enters the delivery tube 5 at the dosing bottle 8 and is difficult to be discharged. After the medicine liquid is completely pumped into the drip bottle 7 under the action of the air pump 28, the control valve 13 at the drip bottle 7 is closed to reduce the situation that the medicine liquid inside the drip bottle 7 flows back from the conical block 10 to the delivery tube 5 after the air pump 28 stops working; when the medicine liquid is mixed and the medicine liquid at the dosing bottle 8 is completely extracted, at this time, as the liquid level of the medicine in the delivery tube 5 at the dosing bottle 8 drops, the floating The ring 29 will then drop synchronously and push down the residual liquid medicine on the inner wall of the delivery tube 5, so that the mixed liquid medicine can be more fully utilized; by setting the shape of the guide groove 11, the contact area between the conical block 10 and the rubber cover is reduced without affecting its normal operation, thereby reducing the resistance when it pierces the rubber cover, and when the liquid medicine flows from the guide hole 12 between the slider 9 and the rubber cover, the guide sleeve 30 can promote the liquid medicine there to flow out of the guide groove 11 in the slider 9, so that the liquid medicine can be discharged more fully. ;
