Description
Technical field
The utility model relates to a kind of secondary filter no-needle transfusion connector, in particular to the sealing of infusion connector and
The technological improvement of filter structure.
Background technique
Infusion is one of most common treatment and nursing means of clinical care, and the quality of infusion treatment directly affects
The disease healing time of patient.Transfusion particle refers to that the non-metabolism granule foreign in input liquid, pollution of transfusion particles in clinical therapy refer to
Transfusion particle is brought into human body in infusion process, and the process seriously endangered is caused to human body.As country is to transfusion particle management
Increasingly pay attention to, state administration supervision department constantly improves infusion apparatus and perfect.Filtering has been installed additional on many infusion apparatuses
Device, research have shown that this device can cut stifled particle in infusion process, have largely ensured the safety of patient.It is clinical
In, some patients need through venoclysis Chinese medicinal liquid, since Chinese medicinal liquid is made by Chinese herbal medicine, place meeting after a period of time
Sediment is generated, therefore needs to be filtered medical fluid before being infused, filter method used at present is installed additional in infusion apparatus
One layer of filter screen, precipitating spy are filtered on filter screen, and filtering is not thorough, and using effect is bad.In addition to no-needle transfusion connector
Filter structure design it is unreasonable outer, infusion connector is led in use, liquid is easy to ooze out from the sealing position of upper cover and lower cover
Causing infusion connector, there are certain risks.
Utility model content
The utility model provides a kind of secondary filter no-needle transfusion connector, and the technology for solving infusion connector excellent sealing is asked
Topic, improves the sealing effect of infusion connector.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution:
A kind of secondary filter no-needle transfusion connector, which is characterized in that fastened by upper cover and lower cover sealing and form an inner cavity, silicon
Glue valve is placed in the inner cavity, and silica gel valve and lower cover are tightly connected to form infusion channel, forms a kerf on silica gel valve, notch with it is defeated
The connection of liquid channel, the filter core of the interior installation stratiform of infusion channel；
The infusion channel in the feed liquor direction of the filter core forms a flaring, and the periphery of flaring, which reclines, is sealed in the feed liquor of filter core
On face；
The filter core is extruded between silica gel valve and lower cover；
The filter core is that high molecular polythene is sintered to be formed；
Arc reinforcing rib along inner wall protrusion is set on the annular groove inner wall that the lower cover is connect with remaining needle inlet.
The beneficial effect that the utility model generates is to improve the sealing performance of no-needle transfusion connector, specifically in upper cover and
A built-in silica gel valve in the inner cavity of lower cover, silica gel valve and lower cover are tightly connected, and it is logical that infusion is formed between silica gel valve and lower cover
Road opens up notch on silica gel valve, which is connected to the inlet as infusion channel, such silica gel valve and lower cover with infusion channel
Between form sealing structure, sealing structure is also formed between upper cover and lower cover, so that infusion channel has the excellent of double-layer seal
Good sealing effect, in addition, the filter core of the high molecular polythene sintering of stratiform is arranged in infusion channel, so that no-needle transfusion connector
Have a good filter effect, the liquid-transport pipe-line that especially filter core feed liquor is surveyed forms flaring, expand feed liquor survey infusion channel and
The connection area of filter core, improves the filter capacity of filter core.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of one embodiment.
Fig. 2 is partial schematic diagram, shows flaring structure and positional relationship above filter core.
Appended drawing reference
1 notch, 2 silica gel valves, 3 upper covers, 4 infusion channels, 5 flarings, 6 filter cores, 7 lower covers, 8 reinforcing ribs, 9 liquid outlets.
Specific embodiment
It elaborates with reference to the accompanying drawings and examples to the utility model.
Such as Fig. 1, upper cover 3 and lower cover 7 are fastened togather to form inner cavity, built in silica gel valve 2 in the lumen.Upper cover 3 and lower cover 7
It is tightly connected.The top of upper cover 3 is unique opening of inner cavity, and silica gel valve 2 and lower cover 7 are also to be tightly connected, and it is logical to form infusion
Road 4.There is a notch 1, notch 1 is connected to infusion channel 4, the inlet as infusion channel 4 on silica gel valve 2.Needleless is defeated
Liquid device is directly inserted into notch 1, the injection medicament into infusion channel 4, prevents medicament from oozing out from notch 1.Infusion channel 4
Liquid outlet 9 is inserted into the connector of remaining needle.
Such as Fig. 1, sealing structure is formed between silica gel valve 2 and lower cover 7, avoids medicament from oozing out from infusion channel 4, silica gel valve
One stratiform filter core 6 is installed, stratiform filter core 6 plays the role of filtering medicament between 2 and lower cover 7.In order to optimize the filtering effect of filter core 6
Fruit, the filter core in the present embodiment are made of the method for high molecular polythene sintering.
Since 4 self structure of infusion channel has long and narrow feature, in order to guarantee that medicament smoothness filters, above filter core 6
The infusion channel 4 of (i.e. filter core towards the direction of feed liquor) forms 5 (referring to Figures 1 and 2) of flaring, is flared 5 and increases infusion
Channel 4 is connected to aperture area with filter core 6.
In addition, the reinforcing rib 8 of several protrusions is arranged on the annular groove inner wall of lower cover 7, improves the entirety of annular groove such as Fig. 1
The safety that firm performance and annular groove are connected with indwelling adapter.
