Description

Technical Field

[0001] The present invention belongs to the technical field of drug heating devices, and particularly relates to a crystallization dissolution device for mannitol injection. Background Art

[0002] Mannitol injection is a commonly used osmotic diuretic, with the main ingredient being mannitol. Clinically, it is mainly used to reduce intracranial pressure, intraocular pressure, and treat acute renal failure, etc. However, the solubility of mannitol in water decreases with the decrease of temperature. 20% mannitol injection is prone to crystal precipitation at low temperature (<20°C). If crystals appear in the injection, direct infusion may lead to increased vascular irritation and thrombosis risk. Therefore, mannitol injection is heated before use to avoid the situation of crystal input into the blood vessel.

[0003] Currently, when heating mannitol injection, generally, the mannitol injection is directly placed in a constant temperature heating box. However, since the constant temperature heating box cannot effectively contact the injection during heating and the whole box is heated during heating, the heating speed is slow, and when rapid heating is temporarily required, a long waiting time is needed, which affects the efficiency.

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 Figures 1 to 8As shown, a mannitol injection crystal dissolving device comprises a box body 1 with a placement cavity 15, a box door 17 rotatably connected to the box body 1 is arranged at the opening of the placement cavity 15, the box door 17 is in contact and sealed with the box body 1, and a control screen 16 is also arranged on the box door 17, the control screen 16 is connected to a temperature sensor located in the placement cavity 15, and the control screen 16 drives the water pump 6, the electric heater, the electromagnet 58 and the motor 22 through a corresponding drive circuit or other existing circuits, and the drive circuits or other circuits for the water pump 6, the electric heater, the motor 22 and the electromagnet 58 are all existing technologies, so they are not repeated here;

[0034] A placement plate 18 is provided in the placement cavity 15, and heating components for placing an infusion bottle or an infusion bag are provided on the upper and lower sides of the placement plate 18. After the infusion bottle or the infusion bag is placed on the heating component, the infusion bottle or the infusion bag is gradually heated by the squeezing of the placement plate 18;

[0035] At least two liquid chambers 2 are formed on the side walls of the casing 1 on both sides of the placement chamber 15. The liquid chamber 2 is connected to a hot water device. The liquid chamber 2 is provided with a lifting and adjusting assembly. The lifting and adjusting assembly is connected to a driving assembly located in the casing 1. A strip hole connected to the placement chamber 15 is formed on the side wall of the liquid chamber 2. The placement plate 18 is provided with a convex plate 184 which enters the liquid chamber 2 from the strip hole and is fixed on the lifting and adjusting assembly. The convex plate 184 is slidably and sealedly connected in the strip hole through a sealing assembly. The two liquid chambers 2 are connected through the placement plate 18.

[0036] When in use, the personnel opens the box door 17, sets the placement plate 18 that needs to be worked through the control screen 16, and then places the infusion bottle or infusion bag on the heating component. Then the driving component works, and the lifting and adjusting component drives the corresponding placement plate 18 to move downward. As the placement plate 18 moves downward, the heating component on which the infusion bottle or infusion bag is placed is turned on. At this time, the hot water device supplies hot water to the heating component through the liquid cavity 2, thereby heating the infusion bottle or infusion bag and accelerating the dissolution of the mannitol injection crystals. When it is necessary to take it out, the driving component is controlled to work so that the placement plate 18 is reset;

[0037] When it is necessary to continue heating other infusion bottles or infusion bags, the control screen 16 can be used to set it again;

[0038] For the placement board 18 selected by the control screen 16, the lifting time can be set according to the actual situation, and the corresponding placement board 18 can be controlled to move down when the lifting time is reached;

[0039] Preferably, a corresponding proximity switch may be provided on the box body 1 to detect the closing of the box door 17, and the placement plate 18 controls the corresponding placement plate 18 to move downward after the box door 17 is closed;

[0040] The sliding distance of the placement plates 18 can be selected according to the needs, so that the selected placement plates 18 can be close to each other and squeeze the infusion bottle or infusion bag each time they are used.

[0041] In this embodiment, the heating assembly includes a plurality of first support frames 10 arranged along the length direction of the placement plate 18, the plurality of first support frames 10 are fixed to the upper and lower sides of the placement plate 18, the plurality of first support frames 10 are separated by a partition 104, and an elastic bonding layer 101 is sealed and fixed on one side of the first support frame 10 away from the placement plate 18 to form a plurality of separate heating channels, and water channels 181 are respectively provided at both ends of the placement plate 18 in the width direction, and a one-way valve 182 connected to the heating channel is fixed to the water channel 181, and the one-way valve 182 is used to prevent water from entering the heating channel, and the first support frame 10 is also provided with an extrusion rod 103 that moves up and down with the change of the elastic bonding layer 101, and the extrusion rod 103 can push the one-way valve 182 to open, and the water channel 181 is connected to the liquid chamber 2 through a convex plate 184, and the convex plate 184 is provided with a circular hole 183 connected to the water channel 181;

[0042] The one-way valve 182 is provided with a valve core, which is pushed to contact the valve body by the spring to close the corresponding channel. Therefore, in this embodiment, the extrusion rod 103 is used to push the valve core to move to a position where it is not in contact with the valve body.

[0043] When in use, as the placement plate 18 moves, the infusion bag or infusion bottle squeezes the elastic bonding layer 101 and pushes the squeezing rod 103 downward to open the one-way valve 182. Then, water enters the corresponding heating channel through the water channel 181, and heat transfer is achieved under the action of the elastic bonding layer 101, thereby ensuring the heating speed. When the heating is completed, the placement plate 18 is reset, the elastic bonding layer 101 is reset, and the valve core of the one-way valve 182 pushes the squeezing rod 103 to reset.

[0044] Preferably, multiple one-way valves 182 are set according to the size of the infusion bag and the infusion bottle, so that the corresponding one-way valves 182 can be opened as long as the infusion bag and the infusion bottle are placed on the elastic bonding layer 101, and the water in the water channel 181 can enter the heating channel.

[0045] In this embodiment, a guide block 102 is fixed on the support frame, and a hole is vertically opened in the guide block 102. The extrusion rod 103 is vertically inserted into the hole of the guide block 102 and contacts the valve core of the one-way valve 182. The top of the extrusion rod 103 is round and contacts the elastic bonding layer 101.

[0046] When in use, the guide block 102 is used to guide the extrusion rod 103 to avoid deviation, thereby ensuring the normal opening of the one-way valve 182.

[0047] In this embodiment, the lifting and adjusting assembly includes a threaded rod 4 rotatably connected to the liquid chamber 2, at least one slide rail 3 fixed in the liquid chamber 2, and a plurality of lifting assemblies 5 cooperating with the threaded rod 4. The lifting assemblies 5 are slidably connected to the slide rail 3. The lifting assemblies 5 can be lifted and lowered with the rotation of the threaded rod 4, and are locked on the slide rail 3 when not cooperating with the threaded rod 4. The threaded rod 4 is transmitted to the driving assembly.

[0048] When in use, the lifting assembly 5 cooperates with the threaded rod 4 and is no longer locked with the slide rail 3. At this time, the threaded rod 4 rotates and drives the placement plate 18 to move up and down to ensure the up and down displacement. When the movement is completed, the lifting assembly 5 is locked with the slide rail 3 and disengaged from the threaded rod 4.

[0049] The driving assembly includes a motor 22 fixed on the box body 1, and the motor 22 realizes transmission with the threaded rod 4 through a transmission wheel, a conveyor belt or other transmission components.

[0050] In this embodiment, the lifting assembly 5 includes a lifting shell 53 slidably connected to the slide rail 3, a plurality of arc-shaped threaded plates 59 slidably connected in the lifting shell 53, a guide rod 56 connected to the arc-shaped threaded plates 59, and an electromagnet 58 fixed in the lifting shell 53. The plurality of arc-shaped threaded plates 59 are arranged in a ring shape with the axis of the threaded rod 4 as the center and slide along the radial direction of the threaded rod 4. The side of the arc-shaped threaded plate 59 is provided with a magnet 57 attracted by the power supply magnet 58.

[0051] The guide rod 56 can be inserted into the slide rail 3 to limit the lifting shell 53, the lifting shell 53 is fixed to the convex plate 184, and the arc-shaped threaded plate 59 is elastically connected to the lifting shell 53 through the spring sheet 54;

[0052] When in use, the electromagnet 58 is energized, and the magnetic poles of the electromagnet 58 and the magnet 57 on the opposite side are the same, and the arc-shaped threaded plate 59 is pushed to move toward the threaded rod 4 and engage with it. Then, when the threaded rod 4 rotates, the arc-shaped threaded plate 59 drives the lifting shell 53 to move. When it is necessary to disengage, the electromagnet 58 is de-energized, and the spring 54 pushes the guide rod 56 to insert into the slide rail 3 and causes the arc-shaped threaded plate 59 to disengage from the threaded rod 4.

[0053] Preferably, the guide rod 56 is first inserted into the slide rail 3 and then separated from the threaded rod 4 to prevent the placement plate 18 from falling.

[0054] In this embodiment, one of the guide rods 56 is connected to a locking cylinder 55, the convex plate 184 is provided with a hole for the locking cylinder 55 to be inserted, the locking cylinder 55 is provided with a strip-shaped water hole connected to the round hole 183, the box body 1 is provided with a plurality of locking grooves located on both sides of the strip-shaped water hole, and the locking grooves are arranged up and down; the locking groove is elastically connected to the limit rod 554 through a locking spring 553, the convex plate 184 is provided with a locking hole for the limit rod 554 to be inserted, and the push rod 55 is inserted into the lock hole 2. A displacement hole 551 with a gradually increasing depth is opened along the axial direction on the circumferential side of the locking cylinder 55. One end of the push rod 552 away from the limiting rod 554 abuts against the displacement hole 551. The limiting rod 554 gradually inserts into the locking hole as the push rod 552 moves. When the arc-shaped threaded plate 59 is tightly attached to the threaded rod 4, the limiting rod 554 is flush with the side of the convex plate 184. The upper and lower sides of the convex plate 184 are both provided with inclined splayed grooves, and the inclined grooves correspond to the upper and lower sides of the locking hole.

[0055] When in use, as the threaded rod 4 rotates, the lifting shell 53 moves to a specified position. During the movement, the limiting rod 554 shrinks along the inclined groove into the lock groove. When the lock groove is aligned with the lock hole, the locking cylinder 55 moves, and the displacement rod moves along the displacement hole 551. At this time, the limiting rod 554 is inserted into the lock hole to limit the placement plate 18.

[0056] When unlocking is required, the locking cylinder 55 is controlled to reset;

[0057] One end of the lock hole facing the lock slot is trumpet-shaped. To ensure the alignment of the lock hole and the lock slot, a corresponding distance detection device can be arranged in the placement plate 18 or the placement cavity 15 to ensure the alignment.

[0058] In this embodiment, the ends of the other guide rods 56 extending out of the lifting shell 53 are fixed with the limit plate 51, the limit plate 51 is fixed with the plug connector 52, and the slide rail 3 is provided with a hole for the plug connector 52 to be plugged in;

[0059] Secondary locking is achieved through the cooperation between the limit plate 51, the plug connector 52 and the hole to ensure positioning.

[0060] In this embodiment, the hot water device includes a water tank 9 fixed in the box body 1, a water pump 6 connected to the water tank 9, a pressure regulating assembly 7 arranged in the box body 1, and an electric heating rod 8 fixed in the water tank 9. The water pump 6 is arranged in the box body 1, and the pressure regulating assembly 7 is connected to the water tank 9. The water pump 6 and the water tank 9 are respectively connected to two liquid chambers 2, so that water enters the water tank 9 from the water pump 6 through the liquid chamber 2, the water channel 181, the heating channel, the water channel 181, and the liquid chamber 2. The pressure regulating assembly 7 is specifically composed of a liquid storage barrel and a piston sealed and plugged in the liquid storage barrel. The piston is elastically connected in the liquid storage barrel (not shown in the figure). The water in the water tank 9 can enter the liquid storage barrel when the water pressure in the water tank 9 is too high;

[0061] When in use, the electric heating rod 8 heats water, and the water enters the corresponding heating channel through the water pump 6, the liquid cavity 2, the water channel 181 and the one-way valve 182, and heats the infusion bottle or infusion bag, and returns to the water storage tank 9 through the one-way valve 182, the water channel 181 and the liquid cavity 2;

[0062] Since the water storage tank 9 has limited space, when too many infusion bottles or infusion bags are placed, the water storage space inside the hot water channel 181 is reduced, causing the overall pressure to rise. Therefore, water is stored through the pressure regulating component 7 to ensure normal use.

[0063] In this embodiment, the sealing assembly includes a plug-in slot 14 provided on the box body 1 and a telescopic sealing plate 13 sealedly plugged into the plug-in slot 14. The telescopic sealing plate 13 is sealed against the side wall of the strip hole. The telescopic sealing plate 13 is sealed and fixed on the convex plate 184.

[0064] In this embodiment, the placement cavity 15 includes a medicine bag heating zone 20, a round bottle heating zone 19 and a temporary heating zone 21 from top to bottom. The heating assembly is located in the temporary heating zone 21. The round bottle heating zone 19 and the medicine bag heating zone 20 are both provided with a placement plate 18. A second support frame 11 is fixed to the side of the placement plate 18 of the round bottle heating zone 19. An elastic bonding layer 101 is sealed and fixed on the second support frame 11. A bonding thermal conductive pad 12 is sealed and fixed on the placement plate 18 of the medicine bag heating zone 20.

[0065] The structure of the placement plate 18 of the round bottle heating zone 19 and the medicine bag heating zone 20 and the relationship between the placement plate 18, the lifting and lowering adjustment component and the liquid chamber 2 are the same as the structure of the placement plate 18 of the temporary heating zone 21 and the relationship between the placement plate 18, the lifting and lowering adjustment component and the liquid chamber 2. The temporary heating zone 21 and the round bottle heating zone 19 are not provided with an extrusion rod 103. One of the one-way valves 182 on the placement plate 18 of the round bottle heating zone 19 and the medicine bag heating zone 20 can allow the water in the water channel 181 to enter the heating channel.

[0066] The one-way valves 182 are all spring one-way valves 182;

[0067] When temporary heating is not required, the infusion bottle or infusion bag can also be placed on the placement plate 18 of the bottle heating area and the medicine bag heating area 20 to achieve heating under the action of water flow. In order to ensure that water can enter each area, the one-way valve 182 is used to ensure that the water reaches a certain water pressure before it can be discharged from the other liquid chamber 2.

[0068] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to 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.
