The infusion equipment used clinically at present is usually an infusion bag or an infusion bottle, infusion is carried out in a mode of hanging the infusion bag or the infusion bottle, and conventional nursing can be met; however, not only general patients but also some patients with epilepsy, visual disturbance, mania, inconvenience in legs and feet and the like in hospitals are in danger, when the patients go to a toilet independently, for example, the probability of the epileptic getting ill in a small space such as the toilet is high, after the patients fall down, the infusion tube is possibly torn off by the obstacle in the toilet in the falling down process due to the long pipeline of the infusion tube, the infusion tube is separated from the hands of the patients, or the situation that the pipeline is wound around the bodies of the patients occurs, and the first aid of the patients is hindered; moreover, the patients with inconvenient legs and feet and poor eyesight are easy to fall down or the pipeline is hung on an obstacle or a door handle, so that the problem that the needle head falls off is easily caused; therefore, the applicant provides a medical portable hanging-free self-priming infusion device, which can solve the problem of overlong infusion tube, and the specific implementation mode is as follows:

the existing scheme is provided with a suspension bracket, an infusion bag or an infusion bottle; the suspension bracket can slide on the ground; in practical use, however, the patient needs to push the suspension bracket when going out, and generally holds an infusion bag or an infusion bottle by hand in clinic; when the suspension bracket is adopted, the infusion tube is easy to hang on a barrier, and when the suspension bracket is handheld, the height of the infusion tube is always higher than that of the needle head, so that backflow is avoided, and the problem of arm fatigue is easily caused; and usually require assistance from others when going to the toilet, but in practice many patients are unaided. In the scheme, the take-up box is arranged at the middle section of the infusion tube, and when the infusion bag needs to be hung, the infusion tube can be partially pulled out and fixed; when going to the toilet or going out, the transfusion tube can be recovered for a part of length; when the infusion tube is short, the infusion tube is not easy to be torn off by the barrier, and the condition that the infusion tube is wound around the patient is thoroughly avoided. Therefore, the scheme can avoid the problems that patients with epilepsy, inconvenience in legs and feet and poor eyesight have the problems that the life safety is influenced because the infusion pipeline is long and fixed and is easily torn off by the barrier when a disease occurs or a dark space is removed. The applicant also finds that the existing mode of hanging the infusion bag and the infusion box is not suitable for the field or disaster relief situation, under the actual rescue situation, the infusion bag hanger cannot be carried, the infusion bag is generally held by hands, the height of the infusion bag higher than the needle head needs to be ensured constantly, otherwise serious influence can be caused to a patient, the patient needs to be sent to a centralized medical area to find the hanger, two rescue workers are needed for lifting the patient to the medical area originally, when infusion is needed, one person is required to hold the infusion bag or the infusion bottle, namely at least three persons are needed to transport the patient, more medical resources are undoubtedly occupied, and the rescue speed is reduced. In the scheme, the infusion bag is placed in the shell for fixing, the peristaltic pump is arranged on the infusion tube, and the drugs in the infusion bag are injected into a receptor in a mode that the peristaltic tube is extruded by the peristaltic pump; compared with the existing infusion mode by hanging the infusion bag, the scheme does not need a hanging frame and ensures that the infusion bag is higher than the needle head, thereby thoroughly avoiding the problem of blood backflow; and particularly under the condition of emergency rescue, such as earthquake, the hanging rack shakes violently, and the problem that the infusion bottle or the infusion bag shakes and falls off can occur, thus causing panic to the psychology of the patient; and direct settle infusion bag in this scheme in the shell, even the earthquake condition appears, the condition that infusion bag dropped can not appear yet, can normally infuse the patient, has guaranteed patient's life safety. In addition, the applicant researches and discovers that if the peristaltic pump and the take-up box are arranged on the infusion tube at the same time, and the infusion bag, the peristaltic pump and the take-up box are all arranged inside the shell, the infusion tube can be used in practice; the shell can be fixed on the waist of a patient, when the needle is inserted into the back of the hand of the patient, the distance between the waist and the back of the hand is short, namely the length of the infusion tube outside the shell is short; when the patient stretches the body and the like, the length of the infusion tube pulled out is lengthened, so that the length of the infusion tube pulled out can be controlled by the take-up box according to the activity state of the patient; so as to avoid the situations that the transfusion tube is torn off and the transfusion tube is wound on the body of the patient due to the overlong transfusion tube; especially for special patients (e.g., epileptics, inconvenience of hands and feet, visual impairment, etc.); and under the disaster relief condition, if the infusion set in this scheme is adopted, during rescue, only need to fix infusion set at wounded's health or stretcher etc. position can, need not to adopt and hand, and infusion tube length is adjustable, adopts peristaltic pump extrusion peristaltic tube, produces the negative pressure of certain direction, makes liquid and air flow to fixed direction, carries out the mode of infusing to the patient, more can be adapted to the condition of emergency rescue to need extra medical staff to hand medical bag, save medical resources, the more wounded of rescue.

Specifically, be provided with the center pin in the receipts line box, the center axle circle cover is established on the center pin, be provided with clockwork spring in the center axle circle, clockwork spring sets up and is the circle around the center pin, and clockwork spring's one end is fixed with the center pin, and the other end is fixed with the center axle circle. In the scheme, in the actual use process, the infusion tube is wound on the outer side of the central shaft ring, the clockwork spring is positioned in the central shaft ring and wound on the central shaft, when the hand of a patient extends, an outward tension effect is exerted on the wire outlet end of the wire collecting box, the infusion tube enables the central shaft ring to rotate (set to rotate in the forward direction), at the moment, a part of the infusion tube is pulled out, when the hand of the patient is close to the shell, the outward tension effect exerted on the infusion tube disappears, at the moment, the central shaft ring rotates in the reverse direction under the action of the spring clockwork spring in the central shaft ring, and at the moment, the pulled-out part of the infusion tube retracts into the wire collecting box, so that the scheme can adapt to the action state of the patient; and the infusion tube positioned outside the shell can be provided with a limiting ring, the outer diameter of the limiting ring is larger than the pipeline outlet, the shortest distance of the infusion tube outside the shell can be limited, and the limiting ring can be adjusted according to the preference of a patient.

Further, a safety bag is arranged between the peristaltic pump and the take-up box. The safety bag is a safety pressure storage bag, comprises a precise medicine adding port, can be added with a trace amount of liquid medicine, can exhaust air and can extract gas liquid; the pressure relief port is arranged, when the pressure reaches a set value, the liquid in the pressure storage bag is discharged, the pressure is stopped after the pressure is kept at the set value, and due to the fact that a certain pressure storage function is arranged in the pressure storage bag, blood can be kept in a static state and cannot flow backwards, when the transfusion is blocked, the liquid is discharged, the cabin body senses and alarms to stop transfusion, and a set transfusion threshold value is kept to wait for medical staff to handle. The water outlet of the pressure storage bag adopts a superfine hard tube to take out and output liquid in the middle point of space, so that the pressure storage bag can allow a certain amount of other liquid to exist and cannot be output to an output end no matter what state the pressure storage bag is in, an emergency stop switch (can close an infusion terminal to output liquid and is used in emergency), and a standard infusion interface (is compatible with various existing intravenous puncture needles).

Preferably, be provided with the fixed band on the shell, still including can twine the solid fixed ring at patient's waist, the fixed band can be fixed with solid fixed ring. The shell can be fixed on the waist of a patient, and if the shell is fixed on the arm, the arm of the patient can be inconvenient to extend due to the fact that the infusion device is heavy; therefore, the waist part is fixed, so that the patient can move normally, and the arm movement of the patient is not influenced.

The fixing ring can be bent and deformed; the surface of the fixing ring is provided with a magic tape; the fixing belt can be matched and connected with the magic tape. The adhesive mode is convenient for fixing and can be used repeatedly; compare and adopt to set up the draw-in groove on solid fixed ring, set up the mode of fixture block on the shell, simple structure, cost are low to can hug closely with patient's health, avoid heavier object to hang and arouse the condition of uncomfortable sense easily at the waist.

The infusion bag further comprises a display screen, wherein the display screen is arranged on the surface of the shell and can display the dosage of the infusion bag and the amount of bubbles in the infusion tube in real time. Clinically, when adopting infusion bag infusion, generally rely on nurse or patient self macroscopic observation to confirm infusion bag's surplus, if under the busier condition in hospital, the condition that does not in time change dressings appears easily, consequently this scheme is provided with the display screen outside the shell, the dose in the infusion bag that the display screen can show to detect out to can give nurse voice prompt or report to the police etc.. And the applicant found that: if the air quantity entering the human body is large and rapid during transfusion, air embolism can occur. Because the air inlet amount is large and rapid, the air and the blood in the heart chamber are stirred after the heart beats to form a large amount of foams which are equivalent to emboli; when the right heart contracts, pushing these emboli to the branches of the pulmonary artery at all levels causes the pulmonary artery to block, causing a respiratory circulatory disturbance; therefore, the shell is also internally provided with the bubble detection device which can detect the amount of bubbles in the infusion tube, and when the amount of bubbles endangers the body of a patient, the alarm is given in time.

Preferably, the inner cavity of the wire-rewinding box is larger than or equal to the outer diameter of the infusion tube and smaller than two times of the outer diameter of the infusion tube. The height of the inner cavity of the take-up box in the scheme is larger than the outer diameter of the infusion tube and smaller than the two times of the outer diameter of the infusion tube, so that the infusion tube can smoothly enter the take-up box, and the problem that the infusion tube is wound in the take-up box in a disordered manner is solved.

The applicant finds that in the research process, when a patient extends an arm, the infusion tube is bent to a greater extent at the position of the outlet of the pipeline, that is, when the patient extends, the inner wall of the outlet of the pipeline may obstruct the infusion tube from extending out of the shell to a certain extent or damage the outer surface of the infusion tube to a certain extent; the applicant has therefore made the following improvements in view of the above problems: the pipeline outlet is formed in the shell, a first ring body is arranged in the pipeline outlet, the outer diameter of the first ring body is smaller than the inner diameter of the pipeline outlet, the first ring body is connected with the inner wall of the pipeline outlet through a first connecting rod, a plurality of first rotating cylinders are sleeved on the first ring body, and the first rotating cylinders can rotate around the first ring body. In the in-service use in-process, when the transfer line was pulled out, the transfer line can make first a rotary drum rotate around first ring body, turns into rolling friction when sliding friction, can effectively alleviate the restriction of pipeline export to the transfer line. Preferably, the outer surface of the first rotating cylinder is sleeved with a sponge cylinder. Because the patient moves when more, the transfer line is constantly dragged, and the surface of transfer line produces the damage easily, consequently establishes a sponge section of thick bamboo after the surface cover of a first section of thick bamboo that rotates, can avoid the transfer line to a certain extent at the tensile and damage problem that the back retraction in-process caused.
