Description
Technical field
The present invention relates to technical field of medical equipment, specially a kind of connection method of PP dialyzer shell and end cap.
Background technique
Current dialyzer sheathing material is medical grade PC material, has good stability of the dimension, high mechanical strength, temperature tolerance
The characteristics such as good；Since PC material contains plasticizer, so the PP shell of plasticizer-containing is not the main side of dialyzer shell in future
To.But PP the material stability of size, mechanical strength and temperature tolerance compared with PC material are all much worse than greatly PC material.So PP
The product design of material cannot continue to use the thread connecting mode that PC material uses always.The direction of major part producer research and development at present is
Ultrasonic bonding mode connects PP shell and end cap.But ultrasonic bonding can generate dust due to high frequency vibration friction, this is right
It is totally unfavorable for the patient that dialyzer is used for a long time.
Summary of the invention
The purpose of the present invention is to provide the connection methods of a kind of PP dialyzer shell and end cap, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the invention provides the following technical scheme: a kind of connection side of PP dialyzer shell and end cap
Method includes the following steps,
S1: deep gouge is opened up respectively on PP shell, PP end cap；
S2: PP shell, PP end cap are mutually aligned, deep gouge is mutually aligned；
S3: upper connecting band is covered on the deep gouge on PP shell, PP end cap；
S4: will heat connecting band, be heated to cooling after molten condition.
Preferably, the PP shell both ends open, there are two the settings of PP end cap, connect respectively with PP shell both ends.
Preferably, nozzle is provided on the PP end cap sidewall and end face respectively, in PP shell, PP cover internal
Sky, nozzle and PP shell inner cavity are interconnected.
Compared with prior art, the beneficial effects of the present invention are: the present invention by the way that connecting band is heated to molten condition after
It is cooling, to be attached to PP shell, PP end cap；The dialyzer interiors of products made by using this method will not generate powder
Dirt, and the connection of PP shell, PP end cap is reliable, good seal performance, while appearance is preferable, clearer can identify artery and vein end.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is PP shell of the invention, PP end cap connection schematic diagram；
Figure label: 1, PP shell；2, PP end cap；3, connecting band.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that the orientation of the instructions such as term "vertical", "upper", "lower", "horizontal"
Or positional relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description of the present invention and simplification of the description, and
It is not that the device of indication or suggestion meaning or element must have a particular orientation, be constructed and operated in a specific orientation, therefore
It is not considered as limiting the invention.
In the description of the present invention, it is also necessary to which explanation is unless specifically defined or limited otherwise, term " setting ",
" installation ", " connected ", " connection " shall be understood in a broad sense, for example, it may be fixedly connected, may be a detachable connection or one
Connect to body；It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, it can also be indirect by intermediary
It is connected, can be the connection inside two elements.For the ordinary skill in the art, it can manage as the case may be
Solve the concrete meaning of above-mentioned term in the present invention.
The present invention provides a kind of technical solution referring to FIG. 1-2: a kind of connection method of PP dialyzer shell and end cap,
Include the following steps,
S1: deep gouge is opened up respectively on PP shell 1, PP end cap 2；
S2: PP shell 1, PP end cap 2 are mutually aligned, deep gouge is mutually aligned；
S3: upper connecting band 3 is covered on the deep gouge on PP shell 1, PP end cap 2；
S4: will heat connecting band 3, be heated to cooling after molten condition.
Further, 1 both ends open of PP shell, there are two the settings of PP end cap 2, connect respectively with 1 both ends of PP shell.
Further, nozzle is provided on 2 side of PP end cap and end face respectively, in PP shell 1, PP end cap 2
Portion is hollow, and nozzle and 1 inner cavity of PP shell are interconnected.
Working principle: in step sl, it is heavy to open up respectively on the both ends of PP shell 1 and the connecting end surface of PP end cap 2
Slot cooperates between deep gouge；In step s 2, PP shell 1, PP end cap 2 are mutually aligned, while keep deep gouge mutually right
Together；Later in step s3, by 3 sets of connecting band in deep gouge；In step S4, connecting band 3 is heated, makes to connect after heating
Band 3 is in cooling after molten condition, so that connecting band 3 is attached PP shell 1, PP end cap 2, seals.
It is connected by using connecting band 3, dust will not be generated in interiors of products, and the connection of PP shell, PP end cap is reliable, it is close
Sealing property is good；Meanwhile 3 color of shell of connecting band at 1 both ends of PP shell is different, can be a red-blue, red corresponds to arterial end,
The corresponding tendon and vessel end of blue clearer can identify artery and vein end to distinguish blood flow direction.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
