Description
Technical Field
The utility model belongs to the technical field of medical equipment, relates to a tube flushing device, in particular to a disposable venous transfusion tube flushing device for flushing a transfusion tube in the process of venous puncture transfusion.
Background
In the clinical nursing work, venous transfusion is one of the main work of nurses, when some clinical patients carry out venous transfusion, more than one infusion bottle is usually used, some medicines are incompatible, in the continuous venous transfusion process, physiological saline is needed to wash an infusion tube (called as a flushing tube for short) in the middle, the phenomena of turbidity, condensation, reduction of drug effect and the like among the medicines are avoided, the treatment effect is influenced, and even the life is threatened, secondly, the flushing tube liquid is usually in the specification of 100ml, if the bottles are not connected in time, the flushing tube liquid of the whole bottle is input into the body of the patient, and for the patient with poor cardiac function, the heart preload of the patient can be increased, and the risk of heart failure is aggravated.
At present, the conventional tube flushing method is that after the infusion of a medicine infusion bottle is finished, a puncture needle (puncture head) at the top end of an infusion tube is pulled out and inserted into the infusion bottle filled with normal saline to flush the tube, the tube flushing time is usually about 5 minutes, and then the puncture needle is pulled out and inserted into the infusion bottle of the next medicine to perform the infusion of the next medicine. In the actual operation process, the normal saline in the dropping bottle is usually 100-200 ml, the actual usage amount is less than 30ml, and the residual normal saline in the dropping bottle is discarded, so that great waste is caused; moreover, the puncture needle head is repeatedly pulled out and inserted for many times, so that the workload of medical care personnel is greatly increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a disposable venous transfusion wash tub ware to prior art's not enough, adopting the design theory of casing and floating plug, utilizing normal saline to the buoyancy of floating plug effect, realize the process of wash tub transfusion again earlier effectively, avoid continuous injection medicine the phenomenon that the compatibility is taboo to appear.
The utility model discloses the technical scheme who adopts:
a disposable intravenous infusion tube flushing device comprises a shell and a cone-shaped floating plug, wherein a certain amount of physiological saline is contained in the shell, and the floating plug is arranged in the shell; vertical cavity puncture head is worn to be equipped with at the top of casing, the bottom is provided with the plug mouth, dismantlement formula is provided with the lid on the puncture head, the lid suit is in the periphery of puncture head, the lower extreme of puncture head is located the casing and is provided with rather than the fixed cover of loudspeaker form that is linked together, fixed cover and floating plug phase-match, be provided with the several supporting shoe on the floating plug bottom, utilize the supporting shoe effectively to float the plug and keep apart bottom the casing, the floating plug is located between fixed cover and the casing bottom, according to the size of buoyancy, the reciprocating up-and-down motion of floating plug between fixed cover and casing bottom. The physiological saline has a buoyancy effect on the floating plug, and the conical head of the floating plug floats upwards towards the opening direction of the fixed cover, so that the outer wall of the floating plug is tightly attached to the inner wall of the fixed cover. When the tube flushing is carried out, the cover body is firstly detached, the puncture head on the top of the shell is punctured into the rubber plug bottle cap of the infusion bottle, the upper part of the puncture head enters the inner cavity of the infusion bottle, the outer wall of the floating plug is tightly attached to the inner wall of the fixed cover, so that the medicine in the infusion bottle cannot flow into the shell, the puncture needle head at the top end of the infusion tube is inserted into the rubber plug hole at the bottom of the shell, and the physiological saline in the shell smoothly flows out and washes the residual medicine in the infusion tube, so that the tube flushing is realized. When the liquid level of normal saline in the shell is reduced to a certain height, the buoyancy of the normal saline in the shell is reduced, the floating plug gradually moves downwards under the conditions that the liquid level is reduced and the buoyancy is reduced, so that a certain gap is generated between the inner wall of the fixed cover and the outer wall of the floating plug, the medicine in the dropping bottle flows into the shell through the puncture head, and then flows into the infusion tube in the shell, so that the medicine in the dropping bottle is smoothly injected into a patient, and the medicine injection work is completed.
Furthermore, the puncture head is made of hard materials. Effectively ensures the strength and hardness of the puncture head in use.
Further, the top end of the puncture head is designed to be in a bevel shape. Is beneficial to the puncture head to puncture the rubber plug bottle cap to enter the solution cavity of the drip bottle, and the medicine in the solution cavity enters the shell through the puncture head.
Furthermore, the supporting block is made of light materials. The floating plug can easily drive the supporting block to move up and down, and the total weight of the floating plug and the supporting block is effectively reduced.
Furthermore, 3 supporting blocks are arranged at the bottom of the floating plug. When the floating plug moves downwards to the bottom of the shell, in order to prevent the bottom of the floating plug from directly plugging the rubber plug opening at the bottom of the shell, the supporting block is utilized to effectively isolate the floating plug from the bottom of the shell.
Furthermore, the amount of physiological saline in the shell is set to be 15-20 ml. Generally, only 15-20 ml of physiological saline is needed for flushing the infusion tube, and waste is caused by adopting excessive physiological saline.
Furthermore, the distance between the bottom of the shell and the bottom of the fixed cover is 20-25 mm. Effectively ensures that the floating plug reciprocates up and down between the fixed cover and the bottom of the shell.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses simple structure, convenient to use through casing, floating plug, fixed cover, puncture head and normal saline's cooperation design, utilizes the normal saline in the casing to the buoyancy of floating plug effect, realizes the process of earlier wash tube reinfusion effectively, avoids continuous injection medicine can take place to mix the phenomenon of taboo.
2. Proper amount of physiological saline is put into the shell to achieve the purpose of flushing the tube, and excessive physiological saline does not need to be put into the shell to cause great waste.
3. The frequency of the plug at the top end of the infusion tube being pulled out and inserted into the drip bottle is effectively reduced, the workload of medical staff is reduced, and the problem that the plug at the top end of the infusion tube is easily led into germs in the air or easily breaks the plug at the top end of the infusion tube in the process of pulling out and inserting the plug at the top end of the infusion tube for multiple times is avoided.
