Abstract
A bag-type infusion apparatus with a liquid medicine filter capable of preventing blood backflow comprises a puncture outfit, an air filter, an inflowing liquid flow regulator, a liquid dividing bag, a dropping funnel, an outflowing liquid flow regulator, the liquid medicine filter and an infusion needle which are connected into a whole through a hose; and the infusion apparatus provided by the utility model is characterized in that a liquid medicine baffle, a support and a baffle base are arranged in the liquid medicine filter. According to the utility model, a general liquid medicine filter is changed to the liquid medicine filter capable of preventing blood backflow, so when the liquid medicine is filtered, the function of preventing blood backflow is also provided, thereby greatly improving the safety of the infusion apparatus; besides, the infusion apparatus has the advantages of simple structure, convenience in operation, low cost and the like, and has a better market prospect.
Description
Technical field
This utility model belongs to armarium, is specifically related to a kind of transfusion device with resistant to blood backflow Pharmaceutical filter.
Background technology
Transfusion device is widely used in clinical transfusion, and it mainly is linked in sequence by perforator, separatory bag or dropping funnel, flow regulator, liquid medicine filter and transfusion needle and forms.Because its frequency of utilization is high, these transfusion devices all are disposable, so the safety of transfusion device also receives publicity.The liquid medicine filter of existing transfusion device does not have the resistant to blood design that refluxes, and its liquid outlet directly is connected with transfusion needle, therefore after the completion of infusing, understands some blood backflow, thereby has had influence on the healthy and safe of patient.
Practical fresh content
This practical new purpose is the deficiency that customer service overcomes above-mentioned existence, provides a kind of simple in structure, easy to operate and can effectively prevent the transfusion device that blood refluxes.
This practical technical scheme that is newly adopted to achieve these goals is following:
A kind of transfusion device with resistant to blood backflow liquid medicine filter; It comprises perforator, air filter, Y-type three way type pipe, dropping funnel, flow regulator, liquid medicine filter and transfusion needle; Be integral through hose connection therebetween; The liquid level that goes out that it is characterized in that the liquid medicine filtering membrane of said liquid medicine filter is provided with the medicinal liquid baffle plate, also is provided with bearing between the liquid outlet of medicinal liquid baffle plate and liquid medicine filter.
This practical new described in medicinal liquid baffle plate lower end be movably connected on the baffle plate base, this baffle plate base is hinged on the annular fixture block that is used for fixing filter membrane.Said medicinal liquid baffle plate is a circular baffle plate, and its diameter is greater than the inlet diameter of liquid medicine filter.Distance between baffle plate base and the bearing is less than the diameter of medicinal liquid baffle plate.
This is practical newly through general liquid medicine filter being changed into a kind of filter that can prevent that blood from refluxing; Therefore can in medical filtration, play the function that prevents that blood from refluxing; Improved the safety of transfusion device widely; Have advantages such as simple in structure, easy to operate, with low cost simultaneously, have market prospect preferably.
Description of drawings
Fig. 1 is this practical new structural representation.
Fig. 2 liquid medicine filter structural representation.
Among the figure: 1-helmet, 2-perforator, 3-flexible pipe A, 4-air filter, 5-exhaustor; 6-tack rubber cap, 7-Y type tee T, 8-dropping funnel, 9-flexible pipe B; The 10-flow regulator, 11-liquid medicine filter, 12-venoclysis needle, 13-medicinal liquid baffle plate; The 14-bearing, 15-baffle plate base, 16-liquid medicine filtering membrane, the ring-like fixture block of 17-.
The specific embodiment
To combine accompanying drawing that this practical new technical scheme is further specified below.
Like Fig. 1, shown in 2: a kind of transfusion device with resistant to blood backflow liquid medicine filter, it comprises perforator 2, air filter 4, Y-type three way type pipe 7, dropping funnel 8, flow regulator 10, liquid medicine filter 11 and transfusion needle 12, is integral through hose connection therebetween.Specifically, perforator 2 tops are covered with helmet 1, and the below connects air filter 4 and is connected Y-type three way type pipe 7 through flexible pipe A through exhaustor 5 respectively, and these Y-type three way type pipe 7 belows connect dropping funnel 8, and the other end seals with tack latex medicated cap.Said dropping funnel 8 belows are through flexible pipe B9 connection traffic actuator 10, and flow regulator 10 liquid outlets connect successively through flexible pipe and have the liquid medicine filter 11 and transfusion needle 12 that prevents that blood from refluxing.These practical new improvements just are to set up a medicinal liquid baffle plate 13 at the liquid level that goes out of the liquid medicine filtering membrane of liquid medicine filter 11, and between the liquid outlet of this medicinal liquid baffle plate 13 and liquid medicine filter 11, also are provided with bearing 14.Its herb liquid baffle plate 13 lower ends are movably connected on the baffle plate base 15, thereby can swing, and can the inlet sealing of liquid medicine filter 11 be prevented liquid return when swinging to vertical-horizontal position thing.This baffle plate base 15 is hinged on the annular fixture block 17 that is used for fixing filter membrane 16.This medicinal liquid baffle plate 13 is made as circular baffle plate, and its diameter is greater than the inlet diameter of liquid medicine filter 11.Distance between baffle plate base 15 and the bearing 14 is set to the diameter less than medicinal liquid baffle plate 13.Therefore when medicinal liquid from top to bottom, when filter inlet gets into, filter earlier at liquid medicine filtering membrane 16 places; Wash the medicinal liquid baffle plate then open, the middle part of baffle plate is leaned against sit on 14, when blood refluxes when making that medicinal liquid is counter to flow; Under the fluid pressure situation, medicinal liquid baffle plate 13 closures stop blood to reflux.Therefore basis is practical has newly added active round medicinal liquid baffle plate in the liquid medicine filter the inside, prevents that blood from refluxing; Baffle plate base strand is connected on the annular fixture block, makes to sit that to drive the medicinal liquid retaining movable at the bottom of the baffle plate; The bearing that adds is that anti-baffle plate blocks medicine outlet and the baffle plate stretching is opened very much, and medicinal liquid can not make the medicinal liquid baffle plate closed when refluxing; Therefore this transfusion device is made simple, with low cost.
