Description

Transfusion exhaust device

Technical Field

The invention relates to a nursing device, in particular to an infusion exhaust device.

Background

Venous transfusion is an important treatment means, and because the venous transfusion is directly aimed at human blood, the safety of the venous transfusion is very important, and the venous transfusion has a plurality of potential risks, wherein the common risks are that air is mixed in a transfusion tube, and serious consequences can be caused if the air is not discharged, and even the life of a patient is threatened. Currently, nurses often vent air using the following methods:

1. when air exists in the infusion tube, a nurse utilizes fingers to flick the infusion tube lightly, so that the air slowly moves upwards under the action of buoyancy until the air is discharged into the Murphy's dropper, the method needs the patience and experience of the nurse, and the air is not easy to be completely discharged due to time waste.

2. The nurse exhausts by using the pen, the infusion tube is wound on the pen in a mode, then the pen moves upwards to extrude the infusion tube, and air in the infusion tube is discharged into the Murphy's dropper.

3. When the method is difficult to exhaust air, the regulating valve of the infusion apparatus is closed firstly, the joint of the infusion pipeline and the infusion needle is disconnected, then the regulating valve of the infusion apparatus is opened to allow liquid mixed with gas to flow out, and then the infusion pipeline and the infusion needle are connected again. This method is prone to waste of the liquid medicine and risks contamination of the liquid medicine and infection of the patient.

Detailed Description

The invention will be further explained with reference to the drawings.

As shown in fig. 1, the present invention comprises an exhaust rod 1, and a spiral transfusion tube placing groove 2 is arranged on the exhaust rod 1. When using, with the transfer line along the 2 windings of transfer line standing groove, fixed transfer line lower extreme, then with exhaust stem 1 rebound, the transfer line slides along transfer line standing groove 2 to receive the extrusion of transfer line standing groove 2, thereby extrude the bubble to observing the intracavity gradually, so accomplish the exhaust. The section of the transfusion tube placing groove 2 can be set into various shapes, so that the transfusion tube can be extruded conveniently, and the transfusion tube placing groove can be set into shapes with large top and small bottom, such as a triangle, a trapezoid and the like.

In order to better discharge the bubbles adsorbed on the tube wall of the infusion tube, as shown in fig. 4 and 7, balls 3 or protrusions 4 are arranged on the inner wall of the infusion tube placing groove 2 at intervals, and the balls 3 or the protrusions 4 are arranged at intervals along the extending direction of the infusion tube placing groove 2. Fig. 4 and 7 represent two different embodiments, and fig. 4 is implemented by using the balls 3, and the balls 3 can reduce the friction between the infusion tube and the infusion tube placing groove 2, and simultaneously generate the effect of unevenness, so that the infusion tube can vibrate when sliding, and bubbles attached to the tube wall can be bounced away. Fig. 7 is realized by adopting the convex objects 4, the convex objects 4 are generally spheres and can be in other shapes, and the convex objects 4 generate the uneven effect, so that the infusion tube can vibrate when sliding, and bubbles attached to the tube wall can be flicked away.

In order to facilitate the rotation of the exhaust rod 1, as shown in fig. 2 and 5, the exhaust rod further comprises a grip 5, and the grip 5 is rotatably disposed at an end portion of the exhaust rod 1. The rotation of the exhaust rod 1 can facilitate the upward movement of the exhaust rod 1, namely, the relative sliding of the infusion tube is reduced through the rotation, so that more labor is saved.

In order to facilitate the air discharge, as shown in fig. 2 and 5, a vibration structure 6 is disposed at the rotationally-matched position of the handle 5 and the exhaust rod 1, and when the handle 5 and the exhaust rod 1 rotate relatively, the vibration structure 6 can vibrate the exhaust rod 1. The vibrating structure 6 has various embodiments, which are as follows:

in the present embodiment, as shown in fig. 3, the vibrating structure 6 includes a ball 8 and a groove 10; the handle 5 and the exhaust rod 1 are two mutually matched components, a ball 8 is arranged on one component, and a groove 10 is arranged on the other component; when the handle 5 and the exhaust rod 1 are relatively rotated, the ball 8 and the groove 10 can meet on the motion track. When the ball 8 passes through the groove 10, the ball will be sunk and shaken, so that the exhaust rod 1 shakes when rotating, and the infusion tube is driven to vibrate, thereby being beneficial to gas discharge. The ball 8 and the groove 10 are generally arranged at intervals of one circle, and can also be arranged with a plurality of circles, which can be determined according to the situation.

In this embodiment, the vibrating structure 6 may be an eccentric ball disposed on the handle 5 or/and the exhaust rod 1. When the eccentric ball rolls, the eccentric ball can randomly vibrate, so that the exhaust rod 1 and the grip 5 vibrate mutually, the infusion tube is driven to vibrate, and gas is discharged conveniently.

In the present embodiment, as shown in fig. 6, the vibrating structure 6 includes a protrusion 9 and a groove 10; the handle 5 and the exhaust rod 1 are two mutually matched parts, the bulge 9 is arranged on one part, and the groove 10 is arranged on the other part; when the handle 5 and the exhaust rod 1 are relatively rotated, the protrusion 9 and the groove 10 can meet on a motion track. Every time the bulge 9 passes through the groove 10, the bulge will be sunk and shaken, so that the exhaust rod 1 shakes during rotation, the infusion tube is driven to vibrate, and gas is discharged conveniently. The protrusion 9 and the groove 10 are generally arranged at intervals of one circle, and may also be arranged at multiple circles, which may be the case. The protrusions 9 are spherical, wheel-shaped or tooth-shaped.

In order to better extrude the infusion tube, as shown in fig. 1, the cross section of the infusion tube placing groove 2 is triangular or trapezoidal. The triangle or trapezoid is big outside and small inside. Thus, after the infusion tube is placed in the infusion tube placing groove 2, the infusion tube is gradually extruded by the infusion tube placing groove 2 under the pulling action. The transfusion tube is not only pulled, but also extruded, which is more beneficial to the discharge of air.

Finally, a pen tube 7 can be further arranged, the exhaust rod 1 is hollow, and the pen tube 7 is arranged at one end of the exhaust rod 1 in a telescopic mode. When a nurse needs to write, the pen can be used as a pen.
