Description

Technical Field

[0001] This invention relates to a medical device, and more particularly to a medical liquid treatment device. Background Technology

[0002] In the medical field, the handling of liquid medications is of paramount importance, involving multiple steps such as mixing, extraction, cleaning, and ensuring a sterile environment throughout the process.

[0003] In existing drug solution processing technologies, some devices use simple stirring rods to mix the drug solution. This method offers only a single stirring effect and fails to generate strong convection in both the radial and axial directions, resulting in uneven mixing and affecting the quality and therapeutic efficacy of the drug solution. For example, the stirring shaft of some traditional devices can only rotate in one direction, failing to create a complex stirring motion, making it difficult to achieve thorough mixing of highly viscous drug solutions.

[0004] In terms of preventing contamination, some devices lack effective sealing designs. For example, repeatedly opening the container lid when injecting medication greatly increases the risk of external dust and microorganisms entering the container, easily causing medication contamination and potentially leading to serious consequences such as patient infection.

[0005] Furthermore, existing devices do not provide comprehensive and thorough sterilization of components that come into contact with the pharmaceutical solution. Some devices rely on a single sterilization method, such as ultraviolet irradiation, which fails to effectively sterilize hard-to-reach areas. Critical areas such as the inside of the stirring shaft and the inner wall of the cap can easily become sterilization dead zones, making it difficult to meet medical-grade sterility requirements.

[0006] Furthermore, some existing drug solution processing devices are not convenient or safe to operate. For example, when adjusting the container angle, there is no convenient limiting structure, making the angle unstable and affecting operation; and the operating switches of some devices are poorly designed, requiring medical staff to operate them frequently by hand, increasing the possibility of cross-contamination. Moreover, when processing waste liquid, some devices lack reasonable guidance and control structures, leading to obstructed waste liquid discharge and even potential leakage problems.

[0007] In summary, existing medical liquid treatment technologies have many shortcomings in terms of mixing effect, prevention of contamination, sterilization, ease of operation and safety, and urgently need to be improved. Summary of the Invention

[0008] The present invention aims to solve the problems of uneven mixing, easy contamination, incomplete sterilization, inconvenience and safety of existing medical liquid treatment devices, and to provide a medical liquid treatment device that can achieve aseptic mixing, uniform stirring, complete sterilization and is convenient and safe to operate.

[0009] To address the aforementioned technical problems, the present invention provides the following technical solution.

[0010] A medical liquid processing device includes a base frame, characterized in that the base frame is integrally formed from medical-grade 304 stainless steel with an electrolytic polishing finish; a liquid-suppressing frame is bolted to the top of the base frame, the liquid-suppressing frame being a rectangular cavity structure with an open top; a side frame is welded to the top of the base frame away from the liquid-suppressing frame; a faucet is screwed to the top of the side frame near the lifting rod, the faucet's inlet end being connected to a medical purified water system via a hose, and its outlet end being rotatable 360°.

[0013] In a preferred embodiment of the present invention, the bottom of the drive shaft extends into the cover and a crossbar is fixedly sleeved thereon by a flat key. The two ends of the crossbar are rotatably clamped with a stirring shaft by a miniature bearing. The top end of the stirring shaft is fixedly sleeved with a gear by a set screw.

[0015] In a preferred embodiment of the present invention, the bottom end of the cap is fixedly installed with symmetrically distributed sterilization frames by screws. The sterilization frames have a U-shaped structure, and ultraviolet lamp strips are fixedly mounted on opposite sides of the sterilization frames by slots.

[0016] In a preferred embodiment of the present invention, the sterilization assembly includes a sterilization base frame, an atomizing sterilization instrument, and a buffer liquid base frame. The sterilization base frame is a hollow cuboid structure, fixedly installed on the top left side of the side frame. Symmetrically distributed buffer gas frames are fixedly installed on both sides of its top by welding. The buffer gas frames are hollow structures and communicate with the interior of the sterilization base frame, connected by four connecting pipes. The atomizing sterilization instrument is fixedly installed on the side of the side frame by a bracket. Its output end is connected to an air inlet pipe via a silicone tube.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] like Figure 1-8 As shown, the first embodiment of the present invention provides a medical liquid processing device. The medical liquid processing device includes a base frame (1), which is integrally formed of medical 304 stainless steel and its surface is electrolytically polished.

[0033] A liquid-suppressing frame (2) is bolted to the top of the base frame (1). The liquid-suppressing frame (2) is a rectangular cavity structure with an open top. A side frame (3) is welded to the top of the base frame (1) on the side away from the liquid-suppressing frame (2). The side frame (3) provides stable support for the upper structure of the device.

[0034] On the side of the top of the side frame (3) near the lifting rod (6), a faucet (11) is fixedly installed by screws. The faucet (11) is made of medical grade brass and its surface is chrome-plated. The valve core is a ceramic valve core with a service life of ≥50,000 times. Its inlet end is connected to the medical purified water system through a hose, and the outlet end is a gooseneck tube that can rotate 360°, which is convenient for injecting cleaning water or solvent into the glass flask (5). The faucet (11) is a foot pedal switch to avoid cross-contamination caused by the hands of medical staff.

[0035] The top of the buffer frame (2) is provided with a rotating component (4), and a glass flask (5) is detachably attached to the middle of the rotating component (4). The glass flask (5) is made of medical borosilicate glass.

[0036] like Figure 2 , Figure 3 As shown, the rotating assembly (4) includes a base (41) and a sleeve (43). In the middle of the base (41), there is an arc-shaped groove that fits the bottom of the glass flask (5). A medical silicone pad is attached to the inner wall of the groove. The surface of the silicone pad has anti-slip texture. This can enhance the friction with the bottom of the glass flask (5) and prevent slippage during operation, and also avoid direct contact between the glass material and the glass, which may cause wear or breakage.

[0037] The base (41) is fixedly installed on the outside by a key connection. The central shaft (42) is rotatably installed on the top two side walls of the liquid buffer frame (2) by two sealed bearings. The bearings adopt a double lip seal design, which can effectively prevent the waste liquid in the liquid buffer frame (2) from seeping into the bearing and affecting the rotation performance, and ensure that the central shaft (42) rotates smoothly.

[0038] like Figure 3 As shown, the end of the central shaft (42) passes through the outer wall of the buffer frame (2) and is fixedly fitted with a limiting plate (44) by interference fit. The edge of the limiting plate (44) has three limiting grooves evenly distributed, namely the first limiting groove (441), the second limiting groove (442) and the third limiting groove (443). The included angle between adjacent limiting grooves is 90°, corresponding to the three working postures of the glass flask (5).

[0039] The sleeve (43) is fixedly installed on the outer wall of the buffer frame (2) by welding, corresponding to the position of the limiting plate (44). A limiting plug (45) is movably inserted on the side of the sleeve (43) away from the buffer frame (2). The limiting plug (45) is preferably a rust-proof alloy rod with a hemispherical end, which is convenient to be accurately inserted into the limiting groove. A return spring (451) is fixedly sleeved on the side of the limiting plug (45) away from the limiting plate (44) by a snap ring. The return spring (451) is made of medical grade stainless steel wire. The side of it close to the limiting plate (44) is welded and fixed to the sleeve (43). In the natural state, the return spring (451) is in a slightly compressed state, which can tightly press the limiting plug (45) against the outer wall of the limiting plate (44) to ensure the stability of the glass flask (5) after the angle is fixed.

[0040] When the limit bolt (45) is engaged in the first limit groove (441), as Figure 3 As shown, the glass flask (5) is in a vertical position with its opening facing upwards. This makes it convenient for medical staff to inject drugs, solvents, or add excipients into the flask using a syringe, avoiding splashing of drugs caused by tilting during injection. When the limiting plug (45) is engaged in the second limiting groove (442), the glass flask (5) is in a vertical position with its opening facing downwards. This is suitable for pouring the treated drugs into an infusion bag or a special container, or for draining the wastewater after cleaning. Gravity can reduce the amount of residue in the flask. When the limiting plug (45) is engaged in the third limiting groove (443), the glass flask (5) is tilted at 45°. At this time, the liquid level in the flask and the mouth of the flask form a gentle slope. Medical staff can slowly draw the drugs along the flask wall using a syringe needle. This avoids the generation of air bubbles caused by excessive angle and reduces the amount of drugs remaining at the bottom of the flask. This is especially suitable for the precise use of expensive chemotherapy drugs, biological agents, etc.

[0041] Back Figure 1 ,like Figure 1 As shown, a lifting rod (6) is rotatably mounted on the top center of the side frame (3) via a rotary bearing. The lifting rod (6) is an electric push rod type structure. A crossbeam (61) is fixedly mounted on the output end of the lifting rod (6) via a flange. A mixing component (7) is provided on the side of the crossbeam (61) away from the lifting rod (6) for uniformly mixing the liquid in the glass flask (5).

[0042] like Figure 4 As shown, the mixing component (7) includes a cover (71). In the middle of the cover (71), a drive shaft (72) is rotatably inserted via a precision bearing. The top end of the drive shaft (72) is coaxially fixed to the output end of the motor (10) via a coupling. The motor (10) is fixedly installed on the top of the crossbar (61) away from the lifting rod (6) by screws.

[0043] Two connecting rods (78) are symmetrically welded to the top of the cap (71). The connecting rods (78) are stainless steel rods, and their tops are fixedly connected to the bottom of the crossbar (61) by threads to form a triangular stable support structure. This ensures that the cap (71) does not shake during lifting and mixing, thus guaranteeing the sealing effect. The cap (71) is movably fitted onto the top of the glass flask (5). A sealing gasket (73) is pasted on the lower surface of its inner wall. The edge of the sealing gasket (73) is designed with a rounded transition. When the cap (71) is lowered and fitted, the sealing gasket (73) can fit tightly against the outer edge of the top of the glass flask (5) to form a sealing ring. This can prevent the liquid from splashing during mixing and also block dust and microorganisms in the outside air from entering the bottle, ensuring a sterile environment for the liquid.

[0044] like Figure 5 As shown, the bottom of the drive shaft (72) extends into the cover (71) and a crossbar (74) is fixedly sleeved by a flat key. The crossbar (74) is made of hollow stainless steel and a stirring shaft (75) is rotated and clamped at both ends by miniature bearings. A gear (76) is fixedly sleeved at the top of the stirring shaft (75) by a set screw. An internal gear ring (761) is fixedly clamped on the inner wall of the cover (71) by a slot. The internal gear ring (761) meshes with the gear (76).

[0045] When the motor (10) drives the drive shaft (72) to rotate, the crossbar (74) revolves synchronously with the drive shaft (72). At this time, the gear (76) rolls along the internal gear ring (761), driving the stirring shaft (75) to rotate at a speed of 120 r / min, forming a compound stirring motion, which can generate strong convection in both the radial and axial directions of the liquid.

[0046] On the side of the cap (71) away from the drive shaft (72), a cannula (77) is inserted by heat fusion. The top of the cannula (77) is integrally formed with a rubber sealing plug. The sealing plug adopts a self-sealing design and can automatically close after puncture. An injection tube (771) is movable in the cannula (77). The injection tube (771) is a disposable medical sterile infusion tube. The two ends are connected to the medicine bottle and the puncture needle, respectively. When in use, the needle is inserted into the cannula (77) through the sealing plug. Medicine can be injected into the glass flask (5) in a sealed state, avoiding the risk of contamination caused by repeatedly opening the cap (71). After the injection is completed, the injection tube (771) is removed. The sealing plug can close immediately to maintain the system's airtightness.

[0047] See you again Figure 4 ,like Figure 4As shown, the bottom of the cap (71) is fixed with screws to a symmetrically distributed sterilization frame (79), which has a U-shaped structure. The glass flask (5) is movably connected between the two sterilization frames (79). On the opposite side of the sterilization frames (79), an ultraviolet lamp strip (791) is fixedly installed by a slot. The ultraviolet lamp strip (791) can emit ultraviolet light with strong sterilization effect to sterilize the outer wall, mouth and adjacent area of ​​the glass flask (5).

[0048] like Figure 6 As shown, on the side of the top of the side frame (3) away from the lifting rod (6), there is a sterilization assembly (8) for use with the glass flask (5) and the mixing assembly (7). The sterilization assembly (8) includes a sterilization base frame (81), an atomizing sterilization instrument (82), and a slow-release base frame (84), which can achieve deep sterilization of the parts in contact with the liquid. The sterilization base frame (81) is a hollow cuboid structure and is fixedly installed on the top left side of the side frame (3). On both sides of its top, a symmetrically distributed slow-release frame (83) is fixedly installed by welding. The slow-release frame (83) is a hollow structure and communicates with the interior of the sterilization base frame (81). The two are connected by four connecting pipes (811), which are stainless steel pipes.

[0049] like Figure 7 As shown, a slot (831) corresponding to the sterilization frame (79) is formed between the two air-releasing frames (83). The width of the slot (831) is 1mm-6mm larger than that of the sterilization frame (79). When the sterilization frame (79) is movably engaged in the corresponding slot (831), a relatively closed sterilization space can be formed, reducing the leakage of sterilizing agent. The inner wall of the air-releasing frame (83) is evenly provided with multiple (e.g., 30) through slots (832). The through slots (832) are distributed in a matrix, which allows the atomized sterilizing agent to be sprayed out evenly in a fan shape, ensuring that the stirring shaft (75), the inner wall of the cap (71), and other components are in full contact with the sterilizing agent.

[0050] The atomizing sterilizer (82) is fixedly mounted on the side of the side frame (3) by a bracket. It can hold 35% medical hydrogen peroxide solution and atomizes the solution into particles with a diameter of 1-5 μm by an ultrasonic atomizing plate. The output end of the atomizing sterilizer (82) is connected to the air inlet pipe (821) through a silicone tube. The side of the air inlet pipe (821) away from the atomizing sterilizer (82) is fixedly inserted into the sterilization bottom frame (81) by a connector. The atomized hydrogen peroxide particles enter the sterilization bottom frame (81) through the air inlet pipe (821), and are then distributed to the air buffer frame (83) through the connecting pipe (811). Finally, they are sprayed out from the through slot (832) to sterilize the key components of the mixing component (7).

[0051] like Figure 6 , Figure 7As shown, on the side of the sterilization base frame (81) away from the air inlet pipe (821), a venting pipe (85) is fixedly inserted through a connector. The venting pipe (85) is a polytetrafluoroethylene pipe. On the side away from the sterilization base frame (81), it passes through the side frame (3), the buffer liquid frame (2), and the inclined frame (12) in sequence, and is fixedly inserted into the buffer liquid base frame (84). Part of the atomized sterilizing agent can be introduced into the buffer liquid base frame (84). The buffer liquid base frame (84) is a hollow structure and is fixedly clipped to the middle of the inclined frame (12). The inclined frame (12) is a stainless steel plate with an inclination angle of 15°. It is fixedly clipped to the lower surface of the inner wall of the buffer liquid frame (2) and can guide the liquid to flow to one side.

[0052] A trough (841) is provided on the top of the buffer bottom frame (84) near the glass flask (5). The trough (841) is elongated. When the glass flask (5) is tilted or inverted, the residual medicine, cleaning water or sterilization waste liquid inside it can flow into the buffer bottom frame (84) through the trough (841). A discharge trough (842) is provided on the side of the buffer bottom frame (84) away from the trough (841). The discharge trough (842) is connected to the inside of the buffer frame (2). This allows the liquid flowing in to be discharged into the buffer frame (2) through the discharge trough (842) for buffering. At the same time, the atomized sterilizing agent introduced by the venting pipe (85) can overflow through the trough (841) to assist in sterilization of the inner wall of the glass flask (5) and the inside of the buffer frame (2), thereby improving the overall sterilization effect.

[0053] like Figure 8 As shown, a control valve (13) is fixedly inserted through a flange on the side of the buffer container (2) near the outlet (842). The control valve (13) is a medical-grade ball valve, which is controlled by rotating the handle, making it convenient for medical staff to operate with one hand. When the waste liquid in the buffer container (2) reaches 2 / 3 of its volume, the control valve (13) is opened, and the waste liquid can be quickly discharged under the guidance of the inclined frame (12) and connected to a special medical waste collection bucket. A bracket (14) is fixedly installed on the outer wall of the buffer container (2) on the same side as the control valve (13) by welding. The bracket (14) is an L-shaped stainless steel frame, and a roller (141) is rotatably installed on its top through a bearing. The roller (141) is a silicone wheel, and its outer wall is in contact with the bottom end of the sealing plate (9).

[0054] The sealing plate (9) is a transparent acrylic plate that is slidably mounted on the top of the liquid buffer frame (2) and can slide left and right along the guide rail. When the liquid buffer frame (2) needs to be used or an item is placed on its top, the sealing plate (9) is slid open. The roller (141) can support the free end of the sealing plate (9) so that the sealing plate (9) remains horizontal.

[0055] The specific operating procedure for this device is as follows: Pre-use inspection: Medical staff first put on sterile gloves and check whether each part of the device is intact, the glass flask (5) is free of cracks, the sealing gasket (73) is free of damage, and the motor (10) and lifting rod (6) are operating normally. Pretreatment sterilization is then performed: the glass flask (5) is installed on the base (41), the position of the cap (71) is adjusted by the lifting rod (6), so that the sterilization frame (79) is inserted into the slot (831), the sealing plate (9) is closed, the ultraviolet light strip (791) and the atomizing sterilization instrument (82) are turned on, and the sterilization time is set to 45 minutes (with continuous ultraviolet irradiation and atomizing sterilization for the first 30 minutes). During this period, the atomized hydrogen peroxide particles fill the closed space and thoroughly sterilize the stirring shaft (75), the inner wall of the cap (71), and the inner and outer walls of the glass flask (5). After sterilization, the equipment is turned off and kept closed for 20 minutes to ensure that the sterilizing agent is fully effective. Then the sealing plate (9) is opened, the cap (71) is raised, and ventilation is carried out for 15 minutes to dissipate the residual hydrogen peroxide and avoid affecting the liquid.

[0056] Medication injection operation: Slide open the sealing plate (9), the roller (141) on the bracket (14) supports the sealing plate (9), and place the required medication bottle, sterile syringe, etc. on the top of the sealing plate (9). Pull the limiting plug (45) to disengage it from the limiting groove, rotate the central shaft (42) to drive the base (41) to rotate until the glass flask (5) is facing upward. Release the limiting plug (45), and the reset spring (451) will spring it into the first limiting groove (441) to fix the angle. Turn on the faucet (11) through the foot switch and inject an appropriate amount of medical purified water or solvent (such as physiological saline) into the glass flask (5). After turning off the faucet (11), connect one end of the injection tube (771) to the medication bottle and insert the other end through the sealing plug of the insertion tube (77). Slowly squeeze the medication bottle to inject the medication. During the injection process, you can observe the scale of the glass flask (5) to control the dosage. After the injection is completed, remove the injection tube (771), and the sealing plug will automatically close to maintain the seal.

[0057] Drug mixing operation: Rotate the lifting rod (6) to align the cap (71) with the glass flask (5), start the lifting rod (6) to lower the cap (71) until the cap (71) is on top of the glass flask (5) and the sealing gasket (73) is in close contact with the top of the glass flask (5). Adjust the motor (10) speed according to the type of drug solution: for ordinary drug solutions (such as vitamin mixture), adjust to 300 r / min, for viscous drug solutions (such as fat emulsion injection), adjust to 500 r / min. Turn on the motor (10), the drive shaft (72) drives the crossbar (74) to rotate, the gear (76) rolls along the toothed ring (761) to make the stirring shaft (75) rotate and revolve at the same time, so as to mix the drug solution evenly. During the mixing process, observe the state of the drug solution through the transparent glass flask (5). If necessary, pause and adjust the speed. After the mixing is completed, turn off the motor (10).

[0058] Medication extraction procedure: Activate the lifting lever (6) to raise the cap (71), rotate the lifting lever (6) to deviate it from the top of the glass flask (5), pull the limiting plug (45), rotate the central shaft (42) to tilt the glass flask (5) at 45°, and fix the limiting plug (45) into the third limiting groove (443).
