Abstract
The utility model discloses a safe and falling-off prevention infusion apparatus, which comprises an infusion tube and a puncture needle arranged at one end of the infusion tube; a circular hole is formed in the side wall at the upper part of the puncture needle, an elastic piece is arranged in the puncture needle; the bottom end of the elastic piece is fixedly connected onto the inner wall at the lower part of the puncture needle; a spherical end head is arranged at the top end of the elastic piece and extends out of the circular hole; an extruding button is arranged at the middle lower part of the puncture needle and can push the elastic piece to enable the spherical end head to slide off from the circular hole. When the safe and falling-off prevention infusion apparatus is used for being connected with an infusion bottle, the extruding button is pressed to enable the spherical end head of the elastic piece to slide off from the circular hole in the side wall at the upper part of the puncture needle, so that the puncture needle can be smoothly inserted into the bottle plug of the infusion bottle, after the puncture needle is inserted into the bottle plug successfully, the extruding button is released, the elastic piece returns to the original position under the action of the elastic force to drive the spherical end head of the elastic piece to extend out of the circular hole, and the extended spherical end head is clamped at the upper part of the bottle plug, so that the infusion apparatus can be connected with the infusion bottle more firmly, is not easy to fall off and reduces medical solution waste and pollution.
Description
Technical field
this utility model relates to medical apparatus technical field, particularly a kind of transfusion device.
Background technology
use existing transfusion device when infusing to patient, piercing needle is inserted in the bottle stopper in infusion bottle slightly tractive and is just easy to, drops, particularly for child or comatose patient, the situation that transfusion device comes off is more frequent, transfusion device comes off and causes liquid waste, pollution, also easily there is pricking wound accident, thereby increased medical worker's workload.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of easy to use, infuse safe falling-prevention transfusion device safer.
For solving the problems of the technologies described above adopted technical scheme: a kind of safe falling-prevention transfusion device, comprise tube for transfusion and the piercing needle of being located at one of tube for transfusion, on sidewall above described piercing needle, have a circular hole, in described piercing needle, be provided with a shell fragment, the bottom of described shell fragment is fixedly connected on the inwall of piercing needle below, the top of described shell fragment has a spherical termination of stretching out through circular hole, and described piercing needle middle and lower part is also provided with one can promote the squeeze buttons that shell fragment makes spherical termination disengaging circular hole.
Further, described squeeze buttons is the soft chamber capsule that is convexly set in piercing needle middle and lower part, is provided with the protruding block stretching into in the capsule of soft chamber in described shell fragment middle and lower part.
Beneficial effect: while using this safe falling-prevention transfusion device to be connected with infusion bottle, first pin the circular hole that squeeze buttons makes the spherical termination disengaging piercing needle top sidewall of shell fragment, so that piercing needle can be inserted in the bottle stopper of infusion bottle smoothly, after inserting smoothly, unclamp squeeze buttons, shell fragment is got back to initial position under the effect of elastic force, and then stretch out through circular hole with the spherical termination of spring plate, outwardly directed spherical termination is stuck in bottle stopper top, transfusion device is connected more firm with infusion bottle, should not come off, reduce liquid waste or pollution, reduce pricking wound, also alleviated medical worker's workload.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is described further;
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is the partial structurtes schematic diagram of this utility model embodiment.
The specific embodiment
See figures.1.and.2, a kind of safe falling-prevention transfusion device of this utility model, comprise tube for transfusion 1 and the piercing needle 2 of being located at 1 one of tube for transfusions, on sidewall above piercing needle 2, have a circular hole 21, in piercing needle 2, be provided with a shell fragment 3, the bottom of shell fragment 3 is fixedly connected on piercing needle 2 below inwalls, and the top of shell fragment 3 has a spherical termination 31 of stretching out through circular hole 21, and piercing needle 2 middle and lower parts are also provided with one can promote the squeeze buttons 22 that shell fragment 3 makes spherical termination 31 disengaging circular holes 21.
While using this safe falling-prevention transfusion device to be connected with infusion bottle, first pin the circular hole 21 that squeeze buttons 22 makes the spherical termination 31 disengaging piercing needle 2 top sidewalls of shell fragment 3, so that piercing needle 2 can be inserted in the bottle stopper of infusion bottle smoothly, after inserting smoothly, unclamp squeeze buttons 22, shell fragment 3 is got back to initial position under the effect of elastic force, and then stretch out through circular hole 21 with the spherical termination 31 of spring plate 3, outwardly directed spherical termination 31 is stuck in bottle stopper top, transfusion device is connected more firm with infusion bottle, should not come off, reduce liquid waste or pollution.
In the present embodiment, whole piercing needle 2 upper parts be steel syringe needle, and lower part is the colloid needle tubing being connected with tube for transfusion 1, circular hole 21 is opened on steel syringe needle, and squeeze buttons 22 is arranged on colloid needle tubing, on this colloid needle tubing, be convexly equipped with and form a soft chamber capsule as squeeze buttons 22, shell fragment 3 middle and lower parts are provided with the protruding block 32 suitable with soft chamber capsule size, by pushing soft chamber capsule, just can squeeze protruding block 32, and then drive the spherical termination 31 that is positioned at shell fragment 3 tops to move.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but this utility model is not limited to above-mentioned embodiment, in the ken possessing at described technical field those of ordinary skill, can also under the prerequisite that does not depart from this utility model aim, make various variations.
