Abstract
The utility model discloses a blood backflow prevention safety device for an infusion dropper. The technical scheme includes that an upper infusion tube is connected with the upper end of the infusion dropper, while a lower infusion tube is connected with the lower end of the same; a disconnected floating block arranged in the infusion dropper is a cone capable of floating on the surface of water; the cone top of the floating block is greater than the water in density, the cone bottom thereof is smaller than the water in density, and the diameter of the cone bottom of the floating block is larger than that of the lower infusion tube. During infusion, the cone bottom of the floating block floats on liquid level so as to allow a patient or family members to observe the height of the liquid level and adjust to achieve the best infusion speed; after the infusion, the cone top of the floating block drops into the lower infusion tube firstly, then the cone surface of the floating block has the nozzle of the lower infusion tube sealed, liquid in the lower infusion tube does not flow into or flows into a patient's body at an extremely slow speed to ensure that blood of the patient does not flow back for a long time due to the fact that the liquid is run out of in the infusion tube, so that infusion safety accidents can be avoided.
Description
Technical field
This utility model relates to a kind of auxiliary equipment of transfusion drip tube, relates in particular to a kind of transfusion drip tube resistant to blood refluence safety device.
Background technology
Transfusion drip tube has the effect of being convenient to observe transfusion speed in infusion process, its upper end connects upper tubing, and the lower end connects tube for transfusion down, and following tube for transfusion connects transfusion needle.Existing transfusion drip tube is interior without any parts, so have following defective: after transfusion is finished, liquid in the transfusion drip tube all flows into tube for transfusion down, all flow in patient's body then, if at this moment also do not stop transfusion, then may be because of the less phenomenon that patient's backflow of blood occurs of the pressure in the tube for transfusion, thus the security incident of infusing caused.
The utility model content
The purpose of this utility model provides a kind of transfusion drip tube resistant to blood refluence safety device with regard to being in order to address the above problem.
This utility model is achieved through the following technical solutions above-mentioned purpose:
Transfusion drip tube resistant to blood refluence safety device described in the utility model, the upper end of described transfusion drip tube connects upper tubing, the lower end of described transfusion drip tube connects tube for transfusion down, be provided with the floating block that does not connect in the described transfusion drip tube, the cone of described floating block for bubbling through the water column, the density of the cone top part of described floating block is greater than the density of water, and the density of the awl of described floating block bottom is less than the density of water, and the awl base diameter of described floating block is greater than the described diameter of tube for transfusion down.
In infusion process, the awl of floating block bottom floats on liquid level, is convenient to the patient or family members observe liquid level, regulates best transfusion speed; When transfusion was near completion, the cone top part of floating block at first fell into down in the tube for transfusion, and subsequently, the tube for transfusion ferrule will be descended in the vertebral body surface of floating block, and the liquid in the following tube for transfusion no longer flows into or flows in patient's body with extremely slow speed.
The beneficial effects of the utility model are:
Because when transfusion was near completion, the liquid in the following tube for transfusion no longer flowed into or flows in patient's body with extremely slow speed, can not flow backwards because there being liquid in the tube for transfusion in a long time so can guarantee patient's blood, thereby avoids the security incident of infusing.
Description of drawings
Fig. 1 is the structural representation of transfusion drip tube resistant to blood refluence safety device described in the utility model in infusion process;
Fig. 2 is the structural representation of transfusion drip tube resistant to blood refluence safety device described in the utility model when transfusion is near completion.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, transfusion drip tube resistant to blood refluence safety device described in the utility model, the upper end of transfusion drip tube 2 connects upper tubing 1, the lower end of transfusion drip tube 2 connects tube for transfusion 6 down, be provided with the floating block 3 that does not connect in the transfusion drip tube 2, the cone of floating block 3 for bubbling through the water column, the density of the cone top part 4 of floating block 3 is greater than the density of water, the density of the awl bottom of floating block 3 is less than the density of water, and the awl base diameter of floating block 3 is greater than the diameter of following tube for transfusion 6.
As shown in Figure 1, in infusion process, the awl of floating block 3 bottom float on liquid 5 above, cone top part 4 is sunken in the liquid 5, is convenient to the patient or family members observe liquid level, regulates best transfusion speed; When transfusion is near completion; the cone top part 4 of floating block 3 at first falls into down in the tube for transfusion 6; subsequently; the ferrule of tube for transfusion 6 will be descended in the vertebral body surface of floating block 3; liquid 5 in the following tube for transfusion 6 no longer flows into or flows in patient's body with extremely slow speed; the blood of guaranteeing the patient can not flow backwards because there being liquid in the tube for transfusion in a long time, thereby avoids the security incident of infusing.
Claims (1)
1. transfusion drip tube resistant to blood refluence safety device, the upper end of described transfusion drip tube connects upper tubing, the lower end of described transfusion drip tube connects tube for transfusion down, it is characterized in that: be provided with the floating block that does not connect in the described transfusion drip tube, the cone of described floating block for bubbling through the water column, the density of the cone top part of described floating block is greater than the density of water, and the density of the awl of described floating block bottom is less than the density of water, and the awl base diameter of described floating block is greater than the described diameter of tube for transfusion down.
