[0001] The invention relates to the technical field of rescue nursing, and in particular to an infusion device for helicopter rescue nursing. Background Art

[0002] At present, if you are injured in an accident during outdoor adventure, you need timely rescue. Outdoor adventures, especially in sparsely populated areas, require rescue helicopters to rescue the injured in a timely manner, especially when encountering some injuries with large wounds, which require timely infusion rescue;

[0003] However, the rescue helicopter itself is very bumpy, and the infusion bottle will keep shaking when hanging on the helicopter. This will not only put the infusion bottle at risk of breaking, but also generate a large number of bubbles in the infusion bottle during the continuous bumping process. It is necessary to eliminate these bubbles in time, and the drip bucket in the prior art can eliminate the bubbles in the infusion tube under static conditions. However, under bumpy conditions, the medicine in the drip bucket is equivalent to a small infusion bottle.

DETAILED DESCRIPTION

[0039] Reference Figure 1-Figure 6 The invention discloses an infusion device for helicopter rescue care, comprising an infusion bottle 1 and an infusion tube 7 inserted into the infusion bottle 1, wherein a needle 11 is arranged at the other end of the infusion tube 7, so that the rescued wounded can be provided with emergency rescue on the rescue helicopter.

[0040] Among them, reference Figure 1 and Figure 2 In the shown state, the infusion tube 7 is in a bent state, and the bending of the infusion tube 7 can not only fully utilize the space, but also the bent infusion tube 7 can effectively change the wall-attached position of the bubble group in the infusion tube 7, that is, the exhaust body 10 arranged at the bent protruding part of the infusion tube 7 can better receive the bubble group floating upward, and the bubble group located in the top area of ​​the inner wall of the infusion tube 7 at the bent protruding part of the infusion tube 7 can be well squeezed into the exhaust body 10 as the infusion proceeds, which is convenient for subsequent exhaust operations.

[0041] The infusion tube 7 is also provided with a drip bucket 8 and an exhaust body 10. The drip bucket 8 in the prior art can eliminate bubbles in the infusion tube under static conditions, but under bumpy conditions, the drip bucket 8 will also generate bubbles in the drip bucket and continue to enter the infusion tube 8. Therefore, an exhaust body 10 is required to further eliminate the bubbles in the infusion tube 7.

[0042] The horizontal position of the exhaust body 10 is lower than that of the drip bucket 8. This arrangement can discharge the bubble clusters collected in the infusion tube 7 out of the exhaust body 10 under the action of air pressure. If the horizontal position of the exhaust body 10 is higher than that of the drip bucket 8, then as the liquid separation branch 9 is connected, the position of the bubble clusters in the drip bucket 8 will be lower than that of the bubble clusters in the exhaust body 10, which will cause the liquid medicine in the liquid separation branch 9 to be introduced into the drip bucket 8, and the liquid replenishment operation of the exhaust body 10 will not be performed.

[0043] A liquid branch pipe 9 is connected between the exhaust body 10 and the infusion tube 7 located above the drip bucket 8, and the liquid branch pipe 9 is used to perform a liquid replenishment operation on the exhaust body 10. The infusion bottle 1 is suspended on the rescue helicopter through a balanced suspension mechanism. Figure 3 As shown, the balanced suspension mechanism includes a support ring 2 for lifting and hanging the infusion bottle 1, a weight plate 4 is provided above the infusion bottle 1, and a suspension rope 3 is connected between the support ring 2 and the weight plate 4. It should be noted that such an operation can effectively inject the liquid medicine in the infusion bottle 1 into the body of the injured person, and at the same time can provide a stable support condition for the infusion bottle 1;

[0044] The balancing suspension mechanism also includes a rolling groove 15, which is opened at the top center of the weight plate 4, and the rolling groove 15 is spherical, and the center of the rolling groove 15 is located in the weight plate 4. This arrangement can not only provide support for the rotation of the rotating ball 5, but also prevent the rotating ball 5 from leaving the rolling groove 15 during the rotation process.

[0045] The balance suspension mechanism also includes a rotating ball 5, which rotates in the rolling groove 15. A hook 6 for hanging on the rescue helicopter is fixed on the rotating ball 5. This arrangement can effectively ensure that the infusion bottle 1 can be stably hung on the rescue helicopter through the hook 6;

[0046] A counterweight 12 is also fixed to the outer wall of the weight plate 4 for increasing the stability of the weight plate 4. It should be noted that since the infusion bottle 1 can be stably suspended on the rescue helicopter through the hook 6, when the rescue helicopter is bumpy, the hook 6 will be driven to swing left and right, and the swinging hook 6 will drive the rotating ball 5 to rotate in multiple directions in the rolling groove 15, thereby ensuring that the infusion bottle 1 is always in a vertical downward state, avoiding the bubble clusters generated by the constantly shaking infusion bottle 1 from entering the infusion tube 7.

[0047] The balance suspension mechanism also includes a ball groove 13 formed on the outer wall of the rotating ball 5. A plurality of first rolling balls 14 are arranged in the ball groove 13 to abut against the rolling groove 15. This can effectively reduce the contact area between the rotating ball 5 and the rolling groove 15, so that the rotating ball 5 can rotate more smoothly in the rolling groove 15.

[0048] The balancing suspension mechanism further includes a ball groove opened at the bottom of the rolling groove 15, in which a second rolling ball 16 is arranged to abut against the rotating ball 5 and to maintain the stability of the rotating ball 5, so that the triangular support formed by the plurality of first rolling balls 14 and the second rolling balls 16 at the bottom can support the relatively stable rotation of the rotating ball 5;

[0049] The rolling groove 15 is also filled with lubricating oil to avoid dry friction, which can effectively reduce friction and effectively reduce the impact of the rotation of the rotating ball 5 on the vertical state of the weight plate 4.

[0050] A baffle 17 flush with the top of the weight plate 4 is provided in the rolling groove 15, and the baffle 17 is used to prevent the infusion bottle 1 from excessive deflection. It should be noted that such a setting can not only prevent the leakage of the lubricating oil, but also when the rotating ball 5 is excessively deflected, the first rolling ball 14 carried by the rotating ball 5 will conflict with the baffle 17, effectively preventing the infusion bottle 1 from excessive deflection.

[0051] Reference Figure 4-Figure 6 As shown, a bubble elimination mechanism for discharging bubbles in the infusion tube 7 is provided in the exhaust body 10, and the bubble elimination mechanism includes a first liquid through hole 18 provided in the exhaust body 10, and a plurality of top grooves 19 for storing bubble clusters are provided on the top of the first liquid through hole 18, and the top grooves 19 are inverted arc shapes. It should be noted that this design can effectively make the bubble clusters originally located at the bent and protruding part of the infusion tube 7 gather in the top grooves 19 on the top of the first liquid through hole 18 under the influence of buoyancy when passing through the exhaust body 10, thereby preventing the bubble clusters from flowing with the flow of the liquid medicine, and providing a field for the subsequent elimination of the bubble clusters, so that the liquid medicine without bubble clusters will flow out of the exhaust body 10 under the action of the top grooves 19 on the top of the first liquid through hole 18;

[0052] It should be noted that during use, the bent infusion tube 7 will keep the exhaust body 10 in a horizontal state under the pulling force of the liquid distribution branch tube 9, and the setting of the balanced suspension mechanism can ensure a stable horizontal environment for the collection of bubble clusters.

[0053] The bubble elimination mechanism also includes a gas-liquid exchange chamber 20 opened in the exhaust body 10, and the gas-liquid exchange chamber 20 is connected to the infusion tube 7 above the drip bucket 8 through the liquid separation branch pipe 9, so that part of the medicine liquid originally flowing into the drip bucket 8 can be diverted, that is, diverted to the gas-liquid exchange chamber 20 in the exhaust body 10 through the liquid separation branch pipe 9, and then flows into the first liquid hole 18 with subsequent operations, that is, the volume exchange between the bubble cluster and the medicine liquid is realized, thereby realizing the elimination of the bubble cluster.

[0054] The top of the gas-liquid exchange chamber 20 is set as an inclined surface to prevent the bubble clusters from gathering, so that the bubble clusters flowing into the gas-liquid exchange chamber 20 can be effectively slid out of the gas-liquid exchange chamber 20 along the inclined surface and enter the liquid separation branch pipe 9;

[0055] Multiple top grooves 19 are connected to the gas-liquid exchange chamber 20 through the second liquid hole 21. It should be noted that when the second liquid hole 21 is opened, the bubble clusters gathered at the top of the top groove 19 will rise along the second liquid hole 21 into the gas-liquid exchange chamber 20, and the medicinal liquid originally located in the gas-liquid exchange chamber 20 will quickly fill the part of the space where the bubble clusters leave the top groove 19, thereby realizing gas-liquid volume exchange and ultimately achieving the effect of eliminating the bubble clusters in the top groove 19.

[0056] Reference Figure 5 As shown, the bubble elimination mechanism also includes a plurality of ball-blocking racks 23, which are circumferentially fixed on the top of the top groove 19, and the plurality of ball-blocking racks 23 are evenly distributed below the second liquid-passing hole 21, and the ball-blocking racks 23 are arranged in an L shape, so that when the bubble group gathers at the top of the top groove 19, the light ball 22 that originally floats under the action of the liquid medicine and blocks the second liquid-passing hole 21 will fall, thereby achieving the effect of opening the second liquid-passing hole 21;

[0057] The bubble elimination mechanism also includes a lightweight ball 22, which is located between a plurality of circumferentially distributed ball baffles 23, and the spacing between two adjacent ball baffles 23 is smaller than the diameter of the lightweight ball 22, and the diameter of the lightweight ball 22 is larger than the diameter of the second liquid through hole 21. It should be noted that the arrangement of the lightweight ball 22 can effectively cause the bubble cluster at the top of the top groove 19 to fall under the action of gravity, that is, the second liquid through hole 21 is opened, and after the bubble cluster at the top of the top groove 19 is discharged, the liquid medicine is refilled. The top groove 19 is filled, wherein a rubber edge 24 is provided at the bottom of the second liquid hole 21, and the connection between the rubber edge 24 and the lightweight ball 22 is arc-shaped, so that a sealing effect can be achieved, thereby avoiding a poor sealing effect so that the liquid medicine directly passes through the second liquid hole 21 without passing through the drip bucket 8 and enters the first liquid hole 18, which will not achieve the effect of eliminating the bubble clusters. At this time, the lightweight ball 22 can be vertically upward under the action of a buoyancy greater than gravity to re-block the second liquid hole 21, thereby achieving the effect of eliminating the bubble clusters.

[0058] The working principle of the present invention is as follows: the infusion bottle 1 is suspended on the rescue helicopter through a balanced suspension mechanism, and when the rescue helicopter bumps, the hook 6 will be driven to swing left and right, and the swinging hook 6 will drive the rotating ball 5 to rotate in multiple directions in the rolling groove 15, thereby ensuring that the infusion bottle 1 is always in a vertical downward state, and preventing the bubble group generated by the constantly shaking infusion bottle 1 from entering the infusion tube 7;

[0059] At the same time, the setting of the balanced suspension mechanism can ensure a stable horizontal environment for the collection of bubble clusters;

[0060] When the medicine with bubble clusters passes through the exhaust body 10, the lightweight balls 22 that were originally floating due to the action of the medicine and blocking the second liquid hole 21 will fall down, thereby realizing the opening effect of the second liquid hole 21, and then the bubble clusters gathered at the top of the top groove 19 will rise along the second liquid hole 21 to the gas-liquid exchange chamber 20, and the medicine originally located in the gas-liquid exchange chamber 20 will quickly fill the part of the space where the bubble clusters leave the top groove 19, thereby realizing the gas-liquid volume exchange, and finally achieving the effect of eliminating the bubble clusters in the top groove 19.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
