Abstract
The utility model relates to the technical field of medical apparatus and instruments, in particular to a filter for an infusion set. The filter for the infusion set comprises an upper shell body and a lower shell body which is arranged corresponding to the upper shell body; the upper shell body comprises a liquid inlet pipe, a filter chamber and a liquid outlet pipe in sequence; a filter layer is arranged in the filter chamber; the outer side of the liquid outlet pipe is provided with a fixed connection pipe; a pipe cavity is formed between the liquid outlet pipe and the fixed connection pipe; the lower shell body is in threaded connection with the upper shell body through the pipe cavity. According to the filter for the infusion set, the connection between the upper shell body and the lower shell body is more stable and is not easily loosened, so that an infusion process is safer; in addition, the filter for the infusion set also has the advantages of detachability and convenience for infusion needle replacement, so that when the infusion needle is polluted, the infusion needle can be detached and replaced, the whole infusion set does not need to be replaced, and more cost is saved.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of transfusion device filter.
Background technology
Transfusion device is a kind of process aseptic process for venous transfusion, set up the common disposable medical consumptive material of passage between vein and medicinal liquid, mainly comprise transfusion needle, helmet, tube for transfusion, filter, flow regulator, drip kettle, bottle stopper penetrator etc., in prior art, the hose connection place of tube for transfusion and transfusion needle adopts flexible material to bond together, this connected mode is easily bonding, but be easily subject to external interference and affect filter effect, another kind of mode is to adopt hard material to connect, but adopting hard material to connect easily causes transfusion needle flexible pipe and tube for transfusion to come off, to transfusion, make troubles.
Utility model content
For above-mentioned weak point of the prior art, this utility model aim to provide a kind of filter effect better, the transfusion device filter of difficult drop-off more.
For solving the problems of the technologies described above, transfusion device filter of the present utility model, it comprise upper shell and with the lower house of the corresponding setting of this upper shell, described upper shell comprises feed tube, filter chamber and the drain pipe setting gradually, in described filter chamber, be provided with filter course, drain pipe outside is also provided with affixed pipe, between drain pipe and affixed pipe, forms a tube chamber, and described lower house is threaded with upper shell by this tube chamber.
Concrete, described lower house has union joint, embeds pipe and outlet, and described union joint is arranged at and embeds pipe end, one end, embeds between the pipe other end and outlet and is provided with transition part.
The diameter of described embedding pipe is greater than the diameter of outlet and is less than the diameter of union joint.
Described affixed inside pipe wall is provided with thread groove, and union joint mates setting with thread groove.
On described outlet tube wall, be also provided with rotating vane.
Transfusion device filter of the present utility model, owing to forming a tube chamber between drain pipe and affixed pipe, lower house is threaded with upper shell by this tube chamber, so be connected more stable between upper shell and lower house, be difficult for getting loose, make infusion process safer, in addition, this utility model also has advantages of detachably, is convenient for changing transfusion needle, transfusion needle is connected setting with lower house, so when transfusion needle is contaminated, can dismantles transfusion needle and change, need not change whole transfusion device, more cost-saving.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of filter upper shell for this utility model transfusion device;
Fig. 2 is the structural representation of filter lower house for this utility model transfusion device.
The specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is only this utility model part embodiment, rather than whole embodiment.Embodiment based in this utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of this utility model protection.
As shown in Figures 1 and 2, transfusion device filter of the present utility model, its can comprise upper shell 1 and with the lower house 2 of this upper shell 1 corresponding setting, described upper shell 1 comprises feed tube 11, filter chamber 12 and the drain pipe 13 setting gradually, in described filter chamber 12, be provided with filter course 14, drain pipe 13 outsides are also provided with affixed pipe 15, between drain pipe 13 and affixed pipe 15, form a tube chamber, and described lower house 2 is threaded with upper shell 1 by this tube chamber.Transfusion device filter of the present utility model, owing to forming a tube chamber between drain pipe 13 and affixed pipe 15, lower house 2 is threaded with upper shell 1 by this tube chamber, so be connected more stable between upper shell 1 and lower house 2, be difficult for getting loose, make infusion process safer, in addition, this utility model also has advantages of detachably, is convenient for changing transfusion needle (not shown), transfusion needle is connected setting with lower house 2, so when transfusion needle is contaminated, can dismantles transfusion needle and change, need not change whole transfusion device, more cost-saving.
Concrete, described lower house 2 has union joint 21, embeds pipe 22 and outlet 23, and described union joint 21 is arranged at and embeds pipe 22 ends, one end, embeds between pipe 22 other ends and outlet 23 and is provided with transition part 24; The diameter of described embedding pipe 22 is greater than the diameter of outlet 23 and is less than the diameter of union joint 21; Described affixed pipe 15 inwalls are provided with thread groove 16, and union joint 21 mates setting with thread groove 16.On described outlet 23 tube walls, be also provided with rotating vane 25.
When concrete use, by twisting rotating vane 25, the union joint of lower house 2 21 is twisted in the thread groove 16 of upper shell 1, embed pipe 22 simultaneously and be arranged in affixed pipe 15 and the tube chamber that drain pipe 13 forms, make to be closely connected between upper shell 1 and lower house 2.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
