Description
Technical Field
The utility model relates to a novel intravenous infusion apparatus, in particular to an improved structure which adopts a built-in vacuum infusion bag and generates power through chemical reaction to realize intravenous injection.
Background
The existing intravenous infusion apparatus which is common and used clinically utilizes the action principle of hydrostatic pressure to input required liquid or liquid medicine into veins of human bodies so as to achieve the purpose of treatment.
The existing infusion devices are classified into three types according to their principles: one is an air natural pressure (hydrostatic pressure) type infusion apparatus, which performs in vivo infusion by using the difference between the external air pressure and the blood pressure in blood vessels. Such hydrostatic intravenous infusion devices present a number of inconveniences to the patient and the medical institution: (1) if the transfusion stand is used and the transfusion device needs to be kept at a certain height, the freedom of movement of the transfusion person is limited; (2) once a patient with self-care ability is transfused, the patient needs to be nursed or cared by a person, and the normal living or working ability is lost; (3) and the transfusion can be only carried out in a hospital or clinic, which not only influences the personal life quality of patients. When an emergency happens and needs to be rescued in a large area outside a hospital or rescued in a battlefield, the traditional infusion apparatus isinconvenient to apply, so that the rescue of the wounded is influenced, and the rescue opportunity is even delayed; (4) and the direct contact between the outside air and the sterile liquid medicine easily causes the pollution of the air to the liquid, thereby causing certain danger and disease infection to patients.
Another infusion device utilizes an injection needle tube (or an externally powered injector) to inject and infuse by the principle of manual control pressurization. Although the intravenous injector is accurate and easy to control the infusion speed and the infusion amount, the device cost is high, and the intravenous injector is only suitable for injection of anesthetic during operation or rescue and is not suitable for common clinical or temporary outdoor rescue.
The pressure type injector is also used for infusion by utilizing empty needle mechanical pressure, is not suitable for large-dose injection of common patients, has higher cost and is not suitable for large-scale popularization.
SUMMERY OF THE UTILITY MODEL

In order to further enhance the sealing performance of the liquid medicine in the infusion bag and ensure that the liquid medicine is not mixed with and contacted with the outside air, a sealing gasket can be lined between the sealing cover of the infusion bottle and the flanging of the mouth of the infusion bag.
If the flanging of the opening of the infusion bag is broken,a sealing gasket is used for sealing; if the sealing gasket is damaged, the liquid medicine can be retained in the sealing cover of the infusion bottle, so that the integral sealing effect is ensured.
Through the last puncture needle head of infusion pipeline, can pierce sealed pad and infusion bag sack turn-ups in proper order to switch on infusion bag and infusion pipeline, the liquid medicine can follow the infusion bag and flow into in the infusion pipeline under certain pressure.
The infusion pipeline mainly comprises an upper puncture needle head, an infusion tube, a dropper and a lower puncture needle head.
The upper puncture needle is positioned at the front end of the infusion pipeline, sequentially punctures the sealing cover and the flanging of the opening of the infusion bag and then conducts the infusion bag with the infusion pipeline;
the utility model discloses a get rid of current intake pipe in the infusion pipeline to avoid air and medicine contact, mix, liquid medicine infusion power derives from the pressure that releases after the chemical reagent takes place in the infusion bottle.
A puncture needle head and a dropper are connected to the upper side part of the infusion tube, so that the medicine in the medicine container is introduced into the dropper.
The lower side part of the infusion tube is connected with a dropper and a dropping speed regulator, the dropping speed regulator is sleeved on the peripheral side of the infusion tube, and a pulley type regulator or an external pressure pump regulator can be selected, so that the pressure regulation of the dropping speed of the liquid medicine is realized.
The existing filter is removed in the transfusion pipeline of the utility model, on one hand, the transfusion bag is vacuum filled and has no air mixing; on the other hand, at the bottle mouth of the infusion bottle, the infusion bag, the infusion bottle and the sealing gasket are mutually sealed, so that air is prevented from being mixed. Therefore, the liquid medicine in the infusion pipeline does not need to be filtered to remove impurities.
The lower puncture needle head is positioned at the tail end of the infusion pipeline and is inserted into a vein of an injection site of a patient for injection.
The above contents are the basic contents of the built-in vacuum type intravenous infusion apparatus of the present invention.
The infusion pressure required by the built-in vacuum type intravenous infusion apparatus is provided by the power generated after the reagent is added between the infusion bottle and the built-in infusion bag for reaction.
A part of space is reserved between the infusion bottle and the infusion bag, a reactant is injected into the infusion bottle through an injection opening at the top end of the infusion bottle, and then the sealing plug is sealed from the outside. The gas pressure generated by reaction after the reagents are mixed with each other is released in the infusion bottle, so that the infusion bag with elasticity, retractility and extrusion is continuously pressurized to push the liquid medicine to flow into the infusion pipeline from the bag opening.
The reagent used can be sodium carbonate or sodium bicarbonate and weak acid, and the reaction principle is that carbon dioxide gas and metal salt and water without irritation and corrosiveness can be generated.
The generated carbon dioxide is non-toxic and tasteless. Sodium carbonate reacts more slowly with weak acids than does sodium bicarbonate, which can be used alone or in combination, depending primarily on the particular needs of the patient for infusion.
The weak acid is preferably dilute acetic acid with weak acidity, and the reaction speed and the reaction equilibrium can be controlled.
The specific reaction formula is as follows:
the mixing of the two chemical reagents has no complicated operation requirement, the original infusion bottle is filled with air, the sealing plug is opened and then passes through the injection hole, the two reagents with specified dosage are respectively sucked by the short-needle injection needle and injected into the infusion bottle, and then the injection hole is sealed by the sealing plug, so that the infusion bottle becomes a sealed container.
The bottle body is slightly shaken to fully mix the two chemical reagents and carry out balanced reaction, and the continuously generated carbon dioxide gas continuously expands and extrudes the infusion bag, thereby generating infusion pressure which is larger than the venous blood pressure of the human body.
The built-in vacuum type intravenous infusion apparatus has the following advantages and beneficial effects:
1. the infusion apparatus can realize large-volume liquid infusion, changes the traditional venous infusion into a built-in automatic pressure device which is convenient to carry and does not influence the work and study of a patient, cancels the use of an infusion support, and ensures that the patient can freely walk without being limited by places and environments;
