Description

A medical infusion holding device with alarm function

technical field

The invention relates to the technical field of medical devices, in particular to a medical infusion holding device with an alarm function.

Background technique

Currently, infusion is the most widely used and simple medical method, which can achieve various functions such as treatment, medication, electrolyte and body fluid replenishment, and plays a pivotal role in clinical practice. However, when we perform infusion therapy clinically, especially in the operating room, we often encounter problems such as recording medical documents, anesthesia treatment, performing other operations, and being too busy to take care of infusion management. Evacuation, even passive inhalation of air into the vein, has caused great hidden dangers to clinical work, and also threatened the safety of patients to a certain extent. If an alarm device is designed, then the medical staff can be reminded in time to pull out the needle. .

At the same time, most of the current infusion bottles use straight-hanging hooks, and there is no corresponding clamping device. When the patient needs to move the position, they often need to hold the infusion bottle to move. In this case, if the bottle body shakes and Due to the uncoordinated behavior of the human body, the infusion needle tends to be offset. At the same time, if the bottle body is squeezed, the liquid flow in the infusion tube will increase significantly, which is very unfavorable for the patient's infusion. Two or more drug infusions will be carried out at the same time. Some drugs have better output after mixing. If the drugs can be mixed and input, without the need for medical staff to mix with hand-held syringes, it can not only prevent air infection, but also reduce medical care. The concentration of the drug injected into the human body should reach a certain standard concentration, which should match the pH value of the human body. If the concentration is too low, it will affect the absorption of the drug solution by the human body. Therefore, it is necessary to design a medical infusion holding device with an alarm function that has strong stability and can independently select the mixing ratio of the medicine.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

1-10, the present invention provides a technical solution: a medical infusion clamping device with an alarm function, comprising an infusion stand 1, a clamping mechanism is installed on the upper end of the infusion stand 1, and a mixing mechanism is fixed in the middle of the infusion stand 1 , an alarm mechanism is set on one side of the mixing mechanism, and a speed regulating mechanism is set below the mixing mechanism; when the patient is undergoing infusion, if the infusion bag or infusion bottle shakes, the clamping mechanism can adjust the infusion bottle according to the degree of shaking. Different reactions prevent the patient from moving at the injection needle during infusion, allowing air to enter the interior of the infusion bottle, and the clamping mechanism can fix multiple infusion bottles to achieve subsequent multi-liquid mixing to save a single bottle The time during the infusion, so that the medical staff does not need to mix the medicine by manual injection and suction. By setting the mixing mechanism, the choice can be made according to whether the infusion medicine is mixed. When the infusion is completed, the alarm mechanism works to remind Doctors and patients, when the infusion is about to end, should pull out the needle to prevent the phenomenon of emptying after the end of the infusion. At the same time, when the concentration of the drug is too high, the speed regulating mechanism can change the flow rate of the drug to prevent the drug under high concentration. After being injected into the human body, a relatively strong rejection effect occurs, thereby effectively improving the absorption of the medicinal liquid by the human body.

The clamping mechanism includes a clamping frame 2, a set of clamping grooves 3 is opened inside the clamping frame 2, a bracket 13 is arranged above the clamping groove 3, the inner part of the bracket 13 is rotatably connected with a turnbuckle 12, and a set of clamping grooves are provided. Infusion bottle 1 4 and infusion bottle 2 5 are installed in the inside of 3 respectively, the lower pipeline of infusion bottle 1 4 is connected with connecting pipe 10, the lower pipeline of infusion bottle 2 5 is connected with connecting pipe 2 11, and the inner part of the clamping groove 3 is connected. A number of air cavities 15 are arranged below, and the interior of the several air cavities 15 is slidably connected with a shock-proof plate 16. One side of the shock-proof plate 16 is fixed with a shock-proof block 14, and the other side of the shock-proof plate 16 is connected with the bottom spring of the air cavity 15. The holder 2 is provided with a plurality of air cylinders 17 at the rear positions of the corresponding clamping grooves 3. The interior of the plurality of air cylinders 17 is slidably connected with a moving plate 19. The lower side of the moving plate 19 is fixedly connected with a liquid bag 18, and the interior of the liquid bag 18 is filled with There is concentrated ammonia water, and a group of connecting rods 20 are fixedly connected to the other side of the moving plate 19; when installing multiple infusion bottles, instead of installing multiple infusion bottles on a turnbuckle, the device connects multiple infusion bottles. They are respectively installed in the clamping grooves in the clamping frame, and each infusion bottle is clamped to avoid collision of the infusion bottles during the movement of the infusion frame. When installing the infusion bottle, place the infusion bottle from bottom to top. It is stuck between the anti-vibration blocks, so that the two sides of the anti-vibration block are respectively subjected to outward thrust. Under the action of the thrust, the anti-vibration block pushes the anti-vibration plate connected to it to start sliding toward the inside of the air cavity, and the spring compresses and applies the clamping force to the anti-vibration plate. The force of the infusion bottle toward the inside increases the friction between the bottle wall of the infusion bottle and the shock-proof block, so as to realize the clamping of the infusion bottle by the shock-proof block, and at the same time, the shock-proof plate initially squeezes the gas in the air cavity , so that the gas inside the air cavity enters the interior of the liquid cylinder along the pipeline, and the liquid cylinder pushes the moving plate down after the intake air, so that the moving plate drives the connecting rods on both sides to move down, so as to realize the subsequent middle convex block pairing. The second clamping of the infusion bottle, and the moving plate also squeezes the liquid bladder below.

The interior of the clamping groove 3 is located above the air cavity 15 with a set of convex blocks 25, the interior of the clamping frame 2 corresponding to the clamping groove 3 is provided with a set of liquid grooves 1 21, and the interior of a set of liquid grooves 1 21 slides. A squeeze plate 22 is connected, one side of the squeeze plate 22 is fixedly connected with one end of the adjacent connecting rod 20, and the side of the convex block 25 facing the outside is provided with a second liquid tank 23, and the inside of the second liquid tank 23 is slidably connected There is a push plate 24, the side of the push plate 24 close to the convex block 25 is fixedly connected with the protrusion of the convex block 25, the liquid tank one 21 and the liquid tank two 23 are filled with liquid, and the inside of the liquid tank one 21 is filled with liquid. It is connected with the inner pipe of the liquid tank 23; when the moving plate drives the connecting rod to move downward, the connecting rods on the left and right sides move to both sides respectively; when the connecting rod on the left moves downward, the other end of the connecting rod drives the connecting rod The squeeze plate on the left moves to the left, and the squeeze plate exerts a leftward pressure on the liquid inside the liquid tank 1 on the left. Under the action of this pressure, the liquid enters the inside of the liquid tank 2 on the left through the pipeline. When the inside of the second liquid tank is continuously filled with liquid, the liquid in the liquid tank two pushes the push plate to move to the right, so that the convex block moves out to the right, and the working principle of the right connecting rod is the same as that of the left connecting rod. The convex block on the right protrudes to the left, which effectively realizes the clamping and fixing of the installed infusion bottle by the convex block. The concentrated ammonia water volatilizes ammonia gas under the action of shaking, and the ammonia gas expands the liquid bladder. The expanded liquid bladder exerts an upward driving force on the moving plate. Negative pressure appears in tank 1, so the liquid in tank 2 returns to the inside of tank 1 through the pipeline, and the convex block moves toward the inside of tank 2, then the volume is reduced when the infusion bottle shakes. The contact with the convex block reduces the shaking effect of the infusion stand on the infusion bottle, and at the same time, the moving plate rises to squeeze the gas in the liquid cylinder, and the gas returns to the inside of the air cavity through the pipeline, and the gas in the air cavity Apply the inward thrust of the infusion bottle to the shock-proof block connected to the shock-proof plate, thereby increasing the clamping force between the shock-proof block and the underside of the infusion bottle, and the spring stretches outward, so that the shock-proof block holds the infusion bottle to balance. This can not only reduce the influence of the infusion stand on the infusion bottle when it is shaken, but also increase the stability of the lower end of the infusion bottle, effectively avoiding the gap between the infusion needle and the infusion bottle socket, which will cause air to enter the infusion bottle. , when the infusion bottle stops shaking, the spring inside the air cavity where the shock-proof plate slides begins to retract, and the air cavity is pulled inward to the sliding shock-proof plate. Under the action of the pulling force, the shock-proof plate drives the shock-proof block to return to the initial state, the internal gas returns to the inside of the liquid sac through the pipeline in an equal volume, and the liquid sac expands and drives the moving plate to slide down to the initial state, so that the convex block slowly restores the clamping of the upper half of the infusion bottle, so that The device can automatically change and restore the state when the infusion bottle shakes or stops shaking.

The alarm mechanism includes a warning light 1 251 and a warning light 2 252, and the mixing mechanism includes a control box 6.

The connecting pipe 10 and the connecting pipe two 11 are provided with a liquid passage cavity 29 below the internal clamping point of the control box 6. ;Because most infusion bottles are made of plastic products, when the infusion bottle shakes and the convex block clamps the infusion bottle, the inside of the infusion bottle will be under partial pressure. Under this pressure, the inside of the infusion bottle will enter the connecting tube. The amount of medicine inside will increase. When the infusion bottle normally infuses the inside of the connecting tube, the medicine flows through the pressure-bearing tablet normally. When the amount of medicine output in the infusion bottle increases, the pressure on the pressure-bearing tablet increases. , the pressure-receiving sheet is deformed downward, thereby throttling the input medicine, preventing the dosage of medicine from being too large during infusion, so that the dosage of medicine entering the inside of the infusion tube is too fast, causing discomfort to the human body, and the clamping block is used for connecting the tube. Fixed between the control box and the control box, the warning light is used to monitor the dose of the medicine in the connecting tube one. When the medicine in the connecting tube one is finished, under the action of its internal device, the warning light is on. The second light is used for the monitoring of the drugs in the second connecting tube. The two are in no particular order.

Press the liquid-passing button, and at the same time, the bottom of the liquid-passing button squeezes the liquid in the lower liquid cylinder. The liquid inside the liquid cylinder enters the right cavity of the lower pushing cylinder through the pipeline. The piston plate on the side exerts a leftward thrust, and the push rod moves to the left under the drive of the piston plate and pushes the liquid-passing device to move to the left. When the liquid-passing button is pressed to the position of the limit block, the liquid-passing button is locked and the inside The liquid that can enter the right cavity of the push cylinder enters the right cavity through the pipeline. At this moment, the liquid inlet is aligned with the inside of the connecting pipe. There is a positional deviation in the connection with the connecting pipe, and at the same time, the joint is sealed to prevent the overflow of the medicine when it enters the inside of the liquid-passing device.

The speed regulating mechanism includes a regulating box 7, a regulating chamber 40 is arranged inside the regulating box 7, a fixing rod 41 is arranged in the middle of the regulating chamber 40, the outer bearings at both ends of the fixing rod 41 are connected to the rotating drum, and the surface of the rotating drum is provided with a Set of fan blades, both sides of the fan blades are provided with liquid inlet chambers 421, the surface of the rotating drum is provided with a liquid outlet chamber 422, an elastic bag 47 is installed on the outside of the fixing rod 41, and the inside of the elastic bag 47 is filled with standard concentration reagents , a friction plate 48 is installed on the outer surface of the elastic bag 47, and a permeable membrane 43 is arranged between the friction plate 48 and the elastic bag 47; The blade exerts a turning force, under the action of this force, the fan blade drives the rotating drum to rotate counterclockwise around the fixed rod, and the fan blade stirs the medicine flowing through it during the rotation process, so that the medicine can be mixed more effectively. Since the human body easily absorbs liquids with a slightly higher pH value, the concentration often affects the pH value of the medicine. If the concentration of the medicine is low, the flow rate of the medicine should be reduced. Therefore, when the medicine first comes into contact with the fan blade, part of the mixed medicine enters the The inside of the liquid inlet chamber and the inside of the rotating drum through the pipeline. The osmotic membrane has a one-way osmosis function. If the concentration of the mixed agent is not less than the concentration of the standard concentration reagent, the elastic bladder will start to shrink under the influence of osmosis, and there will be moisture. It flows out, but does not affect the rotation of the fan blade. Part of the mixed agent entering the drum is discharged from the drum through the liquid outlet cavity. At this time, the fan blade is driven by the agent to rotate normally. If the concentration of the mixed agent is lower than the standard concentration of the reagent When the concentration of the medicament enters the drum, the water molecules penetrate into the elastic bag through the osmotic membrane, and the elastic bag begins to expand under the condition of water infiltration until it contacts the interior of the drum. Driven by the bladder, it rubs against the interior of the rotating drum, the liquid outlet cavity and the liquid inlet cavity are blocked by elastic bladders, the medicine cannot pass through the interior of the rotating drum, and the rotating speed of the rotating drum is reduced under the contact with the friction plate, so that the The flow rate of the low-concentration mixed medicament is decelerated, thereby reducing the speed of the liquid flowing in the infusion tube, so that the input speed of the low-concentration mixed medicament can be reduced to prevent the human body from being unable to quickly absorb the medicament.
