Examples
Referring to fig. 1-4, an embodiment of the present invention provides an infusion apparatus, as shown in fig. 1, the infusion apparatus includes a liquid inlet tube 101, a drip chamber column 106, a drip coefficient tube 102, a liquid stop plate 104, a liquid stop chamber column 105, an elastic expansion device 103, a liquid outlet tube 107, and a flow regulator 108. The liquid stopping cavity column 105 is located on the inner top wall of the dropping funnel cavity column 106, and the liquid stopping cavity column 105 is communicated with the liquid inlet pipe 101. The drip coefficient pipe 102 is arranged in one end of the liquid inlet pipe 101 extending into the drip chamber column 106, and the liquid stopping plate 104 is attached to and covers one end of the liquid stopping chamber column 105.
In this embodiment, the specification of the droplet coefficient tube 102 can adopt, but is not limited to, a 10 droplet/ml droplet coefficient tube 102, a 15 droplet/ml droplet coefficient tube 102, a 20 droplet/ml droplet coefficient tube 102, a 30 droplet/ml droplet coefficient tube 102, and a 60 droplet/ml droplet coefficient tube 102, and the larger the tube diameter of the droplet coefficient tube 102, the smaller the droplet coefficient; therefore, in this embodiment, the dropping coefficient tube 102 of 60 drops/ml is preferably used, and the liquid flow can be achieved to reach a straight drop column, so as to reduce the speed error.
When the patient is a child, the dropping speed can be controlled to be 60-120 drops/min, and when the patient is an adult, the dropping speed can be controlled to be 120-180 drops/min, so that the aim of dropping a large number of drops of liquid per minute to form linear dropping can be achieved, and the liquid quantity per drop is small because the pipe diameter of the dropping coefficient pipe 102 is small, so that the liquid cannot be infused too much.
In this embodiment, the liquid stopping plate 104 is made of a light material, for example, the liquid stopping plate 104 may be, but not limited to, a medical sponge plate, a silicone plate, a PVC plate, or a medical barrier film.
One end of the elastic telescopic device 103 is connected with the inner top wall of the dropping funnel cavity column 106, the other end of the elastic telescopic device 103 is connected with the liquid stopping plate 104, the side wall of the dropping funnel cavity column 106 is provided with scale marks 109, one end of the liquid outlet pipe 107 is communicated with the bottom of the dropping funnel cavity column 106, and the flow regulator 108 is arranged on the liquid outlet pipe 107.
In this embodiment, the elastic expansion device 103 may be, but is not limited to, a PVC spring, a stainless steel medical spring, or a medical grade elastic cord. The scale marks 109 are used for representing the infusion speed, for example, the scale marks 109 can be 60 drops/min, 120 drops/min, 180 drops/min, 240 drops/min, and are uniformly engraved on the side wall of the drip chamber column 106.
As one embodiment, as shown in fig. 2, an infrared emitter 111 is disposed at one end of the liquid stop plate 104, and the light beam emitting direction of the infrared emitter 111 is directed to the side wall of the drip chamber column 106 where the scale mark 109 is disposed. It can be understood that the infrared emitter 111 moves along with the liquid stop plate 104, and the light beam emitted by the infrared emitter 111 can hit the scale mark 109 on the sidewall, so that the medical staff can observe the current infusion speed more clearly.
As another embodiment, as shown in FIG. 3, one end of the liquid stop plate 104 is provided with a pointer 110, and the pointer 110 points to the side wall of the drip chamber column 106 provided with the scale mark 109.
As can be appreciated, the pointer 110 moves with the drip stop plate 104 and points to the graduated markings 109 so that the medical personnel can more clearly view the current infusion rate.
As another embodiment, as shown in FIG. 4, two blocking needles 112 are disposed at both ends of the liquid stop plate 104, and one end of each of the two blocking needles 112 is in contact with the inner sidewall of the drip chamber column 106. Considering that when a drip drops onto the drip stop plate 104, the drip stop plate 104 may be left or right shaken to affect the reading of the medical staff, the two stopper pins 112 contacting the inner sidewall of the drip chamber column 106 may prevent the drip stop plate 104 from left or right shaking. Further, as the two blocking pins 112 move along with the liquid stop plate 104, the blocking pin 112 near the scale mark 109 can be used as a pointer 110 and point to the scale mark 109, so that the medical staff can more clearly observe the current infusion speed.
Preferably, the infusion apparatus comprises two elastic telescopic devices 103, and the two elastic telescopic devices 103 are respectively connected to two sides of the liquid stop plate 104, so that the horizontal reliability of the two sides of the liquid stop plate 104 can be enhanced.
In this embodiment, the infusion apparatus may be a light-shielding infusion apparatus, a blood transfusion apparatus, a bucket infusion apparatus, or a hanging bag infusion apparatus.
In this embodiment, the bottom of the chamber column 106 is provided with a liquid medicine filtering membrane, which can prevent large particle impurities in the liquid from entering the blood, and the contact area between the liquid medicine filtering membrane and the liquid medicine in the chamber column 106 is the largest in the whole infusion set pipeline.
In summary, since it is very important to precisely control the infusion speed, which affects the treatment effect of the patient's condition and prevents complications caused by the infusion speed, the infusion apparatus of the present invention attaches and covers the liquid stopping plate on the end of the liquid inlet tube extending into the chamber column of the dropping funnel, one end of the elastic expansion device is connected to the top wall of the chamber column of the dropping funnel, the other end of the elastic expansion device is connected to the liquid stopping plate, and the side wall of the chamber column of the dropping funnel is provided with scale marks, so that when the liquid inlet tube is inserted into the liquid, the column of the dropping funnel is first squeezed to make part of the liquid enter the dropping funnel, then the flow controller is opened, initially, the liquid stopping plate is aligned with the scale mark 0, when the liquid stopping plate drops on the liquid stopping plate through the liquid inlet tube, the liquid stopping plate moves downward under the action of gravity, the opening speed of the flow controller is higher, the descending height of the liquid stopping plate is higher, and the, medical personnel can observe the current transfusion speed according to the reading of the scale marks, so that the precise adjustment of the transfusion speed is realized, no liquid drops on the liquid stopping plate after the liquid is transfused, the liquid stopping plate rebounds to be tightly attached to the liquid inlet pipe, the cavity column of the dropping funnel is closed, the liquid in the dropping funnel cannot drop under the action of pressure intensity to achieve the effect of automatic liquid stopping, the blood of a patient cannot flow back to the liquid outlet pipe, the reliability is high, air can be prevented from entering the transfusion tube to enter the blood vessel to generate air embolism, the working efficiency of the medical personnel can be improved, and the situations that the transfusion tube enters air, the blood return of the transfusion tube, the needle head of the transfusion tube is blocked and the like due to the fact that the liquid is not timely replaced due to the emptying of the transfusion liquid; the patient is facilitated, the transfusion condition is not concerned in real time (timely attention), and the satisfaction degree of the patient is improved.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
