Description
Technical field
The present invention relates to and a kind of carry out venous transfusion medical apparatus and instruments to clinical patients, specifically a kind of automatic liquid-stopping dropping funnel and there is the transfusion device of this dropping funnel.
Background technology
When at present venous transfusion being carried out to patient, widely use disposable infusion set, form primarily of bottle plug puncture unit, air inlet device, dropping funnel, flow regulator, liquid medicine filter, venoclysis needle and some connecting ducts.Under atmospheric pressure effect, the infusion tube that in bottle, liquid runs down is thinner flows into dropping funnel, and when dropping funnel water column pressure is greater than venous pressure, the liquid runs down flexible pipe in bottle flows into vein.In infusion process, need family members to pay close attention to the liquid level of medicinal liquid, otherwise when the liquid level of medicinal liquid is down to dropper lower end, gas enters lower end, as gas instillation blood vessel easily causes air embolism, threat to life safety, leads to malpractice.
In order to solve the problem and the raising day by day of clinical requirement, in succession create the transfusion device that some can be adapted to special clinical requirement.Automatic liquid-stopping transfusion apparatus is exactly a kind of medical treatment consumptive materials replacing the new disposable of general infusion set.Automatic liquid-stopping transfusion apparatus, still needs to carry out gravity infusion, but its feature is when the fast infusion of liquid is complete, can automatic liquid-stopping, automatically avoids air to enter vein.
Chinese utility model patent ZL201210284440.5 safety automation liquid-controlled open-close valve, described safety automation liquid-controlled open-close valve is placed in dropping funnel, it is characterized in that, comprising: valve body, valve gap, upper float and seal; Described valve body comprises a frustum section, and the liquid outlet on described valve body is fixedly connected with the liquid outlet in dropping funnel; Described bonnet central position is provided with the through hole that buoyancy aid connecting rod passes through, and described valve gap snaps onto on valve body; Described upper float is connected with the buoyancy aid connecting rod of seal by hollow, and described upper float is placed in outside valve body; Described seal is frustum, is placed in valve body; Wherein, the contact of incline plane in the sealing surface on described seal and valve body frustum section realizes sealing.
Above-mentioned patent can carry out self-sealing, prevents air from entering in patient body, occurs the situation of blood back.Owing to adopting inclined-plane sealing, sealing surface is large, can cause sealing dead shortcoming, first time infuses end, when carrying out second time transfusion, because buoyancy is large not or other reasons causes buoyancy aid that seal cannot be driven to rise, current employing be extrude dropper with hands, get rid of the gas in dropper, liquid in dropper inhaler, principle upper float floats by the buoyancy of self, but, when extruding dropper, exert pressure up and down, make lower face seal tighter, also dropper will be rocked if desired, seal is made to depart from bottom dropper, such operational motion is many, more time-consuming, easily cause the damage of seal, when hospital busier or special, how to reduce time of changing dressings of medical worker and patient and independently can change dressings and just seem particularly important.
In view of the shortcoming of prior art, one is provided to use continuously, when exchanging infusion bottle and at the end of transfusion nearly, can automatic-sealed be guaranteed, can rise by certain external force when second time transfusion, prevent air from entering in patient body, avoid the situation occurring blood back, improving the reliability of infusion pipeline sealing, improve safety further, is a kind ofly have that good detent plug effect is simultaneously convenient again removes detent plug and the automatic liquid-stopping dropping funnel that can use continuously and the transfusion device with this dropping funnel.
Summary of the invention
The object of the invention is to provide a kind of automatic liquid-stopping dropping funnel, and it is while meeting detent plug effect, convenient releasing medicinal liquid detent plug state.
For this reason, one aspect of the present invention provides a kind of automatic liquid-stopping dropping funnel, comprises the housing, buoyancy aid, seal, hook, upper drain pan and the lower drain pan that are made up of upper shell and lower house, is also provided with a back-up ring in described housing; Described upper shell and lower house grafting form; Described seal is connected to below buoyancy aid, and is placed in housing; Described seal and inclined-plane, housing lower end seal; Described buoyancy aid upper end is provided with a handle, and described handle upper end is formed with a table top, and described handle table top is because pressure make seal depart from inclined-plane sealing, ensureing that transfusion is normal by when pinching the hollow part of dropping funnel; Described upper drain pan and lower house grafting form, and described hook sleeve is connected on lower house and drain pan junction; Described upper drain pan becomes cavity with hull shape of going to the bottom, and is provided with a supporting seat in described cavity, be provided with in described supporting seat can impurity in filter liquide, prevent the filter membrane of blood vessel blockage.
When infusing to prevent secondary, seal cannot normally rise according to buoyancy, described handle is exactly head it off and designs, handle upper end is formed with a table top, as long as gently by the position of hollow part near handle upper end of pinching dropping funnel, under the pressure of dropping funnel tube wall, handle because the pressure of tube wall can make seal depart from sealing inclined-plane bottom dropping funnel easily, and does not need to rock dropping funnel to realize disengaging.
The design of above-mentioned drain pan, mainly based on the needs arranging filter membrane, different with conventional filter independent design, filter membrane is arranged on drain pan lower end, and housing is integrated.
Further, overlap between described lower house and upper drain pan and have above-mentioned hook; Described hook conveniently hangs syringe needle, plays the effect preventing from syringe needle from leaving about injuring other people and facilitate medical worker to treat.
Further, described hook comprises hanger bulk and establishes several coupler bodies equally distributed thereon.
Another goal of the invention according to the present invention provides a kind of automatic liquid-stopping transfusion apparatus, and described transfusion device comprises any automatic liquid-stopping dropping funnel above-mentioned.
Major advantage of the present invention is: can use continuously, when exchanging infusion bottle and at the end of transfusion nearly, automatic-sealed can be guaranteed, easily can rise by handle when second time transfusion, reduce the time of changing dressings and reduce the risk of changing dressings, preventing repetitive operation, improve safety further, is a kind ofly have that good detent plug effect is simultaneously convenient again removes detent plug and the automatic liquid-stopping dropping funnel that can use continuously and the transfusion device with this dropping funnel.
Except object described above, feature and advantage, other object, feature and advantage that the present invention has, will be described in further detail by reference to the accompanying drawings.
