TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to a transfusion pressurizing bag. BACKGROUND

[0002] Clinically, nutrients or therapeutic drugs are often input into patients' bodies in the form of transfusion, when a transfusion bag is connected with a patient, liquid moves to the patient's body at a constant speed under the action of gravity and air pressure, but the transfusion speed of the conventional transfusion mode is relatively slow, and the transfusion speed cannot meet the treatment requirements in the treatment environment such as first aid, therefore, a transfusion pressurizing bag is often wrapped outside the transfusion bag to realize accelerated transfusion by continuously extruding the inside of the transfusion bag.

[0003] However, when the transfusion pressurizing bag is used, gas can overflow from the intermolecular gap of the material of the pressurizing bag itself, so that the air pressure in the pressurizing bag gradually decreases, thereby affecting the transfusion speed of the transfusion bag, and if the medical staff cannot supplement the gas in the pressurizing bag in time, the treatment effect on the patient will be affected.

[0028] The technical solutions of this utility model are clearly and completely described below through specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] An infusion pressure bag, such as Figures 1-8 As shown, it includes: a bag body 1, which has an internal cavity 11, and a ventilation pipe 12 connected to the cavity 11; the bag body 1 has an initial state, and gas enters the bag body 1 through the ventilation pipe 12, causing the bag body 1 to expand; the outer wall of the bag body 1 also has an inwardly recessed pressure chamber 13, which compresses the bag body 1 inward when it expands, thereby accelerating the infusion rate of the infusion bag; when the air pressure inside the bag body 1 gradually decreases and deforms back to its initial state, the pressure chamber 13 compresses the infusion bag. The squeezing effect decreases, thus affecting the infusion process; the alarm component 2 includes a gripper 21 and a sound-emitting element 22. The gripper 21 includes a fixed arm 211 and an actuating arm 212. The actuating arm 212 can rotate relative to the fixed arm 211 around an axis. When the bag body 1 is in the initial state, the fixed arm 211 is connected to the bag body 1, and the actuating arm 212 abuts against the sound-emitting element 22 and makes the sound-emitting element 22 sound. When the bag body 1 expands, it drives the actuating arm 212 to rotate and move away from the sound-emitting element 22.

[0030] In some embodiments of this application, such as Figures 1-8As shown, the bag body 1 further comprises a placement groove 3, the outer wall of the placement groove 3 is attached to the outer wall of the bag body 1, the sound producing member 22 is connected in the placement groove 3, and the placement groove 3 does not deform when the bag body 1 deforms. Specifically, the bag body 1 is made of soft and transparent medical PVC or PP, so that the bag body 1 can be bent and has a certain toughness, and can deform when inflated. The placement groove 3 is made of hard PVC or stainless steel, the edge of the placement groove 3 is welded to the bag body 1, or the placement groove 3 is attached to the outside of the bag body 1. The thickness of the placement groove 3 is not more than 3 mm, and the hard placement groove 3 cooperates with the inflatable bag body 1 to form a cavity 11 in the placement groove 3, which can prevent the execution arm 212 from contacting the loudspeaker 221 when the bag body 1 is not in the initial state. The main cavity wall of the cavity 11 is the placement groove 3, and when the bag body 1 starts to inflate from the initial state, the volume of the cavity 11 increases with the increase of the volume of the bag body 1, thereby continuously pushing the execution arm 212 away from the sound producing member 22. When the bag body 1 is deflated and returns to the initial state, the execution arm 212 falls back and presses the sound producing member 22, so that the sound producing member 22 emits sound, thereby prompting medical staff to know the pressure state in the bag body 1.

[0031] In some embodiments of the present application, as shown in Figures 1-8 The sound producing member 22 comprises a loudspeaker 221 and a button 222, the button 222 is connected to one end of the loudspeaker 221 away from the placement groove 3, when the bag body 1 is in the initial position, the execution arm 212 presses the button 222, and the loudspeaker 221 is attached or clamped in the placement groove 3 and can be detached from the placement groove 3 when the battery is replaced.

[0032] In some embodiments of the present application, as shown in Figures 1-8 The end of the execution arm 212 away from the fixed arm 211 is provided with a limiting piece 2121, the width of the limiting piece 2121 is greater than the width of the placement groove 3, and the execution arm 212 rotates away from the fixed arm 211 when the bag body 1 expands and presses the limiting piece 2121 and the fixed arm 211. The execution arm 212 is further provided with a contact block 2122, and the contact block 2122 extends into the placement groove 3 and presses the button 222 when the bag body 1 is in the initial state. The number of contact blocks 2122 is at least one, so as to ensure that at least one contact block 2122 can press the button 222 when the bag body 1 is in the initial state.

[0033] In some embodiments of the present application, as shown in Figures 1-8 The clamping jaw 21 has elasticity, the bag body 1 can expand to a critical state, the gas in the cavity 11 slowly escapes outward through the bag body 1 and makes the bag body 1 shrink to the initial state when the bag body 1 is in the critical state, the execution arm 212 resets and rotates towards the fixed arm 211 under the action of elasticity when the bag body 1 shrinks, and the execution arm 212 abuts against the sound producing member 22 when the bag body 1 shrinks to the initial state.

[0034] In some embodiments of the present application, as shown in Figures 1-8 The number of the ventilation tubes 12 is one; or, the number of the ventilation tubes 12 is at least two, and at least one of the ventilation tubes 12 is provided with a one-way valve, and gas can only enter the cavity 11 in one direction.

[0035] In some other embodiments of the present application, the clamping jaw 21 is not provided with elasticity, instead, the execution arm 212 and the fixed arm 211 are hinged around a connecting shaft, a torsion spring is sleeved on the connecting shaft, and the two ends of the torsion spring are connected with the execution arm 212 and the fixed arm 211 respectively when the bag body 1 is in the initial state; when the bag body 1 is inflated, the execution arm 212 rotates away from the fixed arm 211 and drives the torsion spring to be compressed and store energy; the bag body 1 can be inflated to a critical state; when the bag body 1 is in the critical state, the gas in the cavity 11 slowly escapes outward through the bag body 1 and makes the bag body 1 shrink to the initial state; when the bag body 1 shrinks, the torsion spring releases energy and drives the execution arm 212 to rotate towards the fixed arm 211; and when the bag body 1 shrinks to the initial state, the execution arm 212 abuts against the sound generating member 22.
