Abstract
The present invention relates to a device for assembling a disposable venous transfusion needle, and an assembling method thereof. The present invention is characterized in that: an orientator 2 is provided with a small hole; a slope which is consistent with a transfusion needle is arranged in the small hole. The method mainly comprises the step of sheathing a handle from the back part of a steel needle so that the projection of the slope of the needle tip is consistent with the plane of the handle. The present invention is characterized in that concurrent engineering and pneumatic control automation are utilized for orienting a needle tube and assembling the needle tube and a needle handle. The present invention replaces a great amount of instable manual operation with poor sanitation condition and quality and low efficiency, substitutes a foreign orienting and assembling mechanism by utilizing a sensor, enhances production efficiency and reduces the cost of equipment.
Description
A kind ofly be used to assemble the device of disposable venous infusion needle head and the method for assembling thereof.
In China, the disposable intravenous infusion set market demand potential is very big, need 1,500,000,000 approximately every year on average, only Liaoning Province just has the manufacturer of 13 tame disposable intravenous infusion sets within the border, but these producers of China are hand assembled at present, and labor intensity is big, productivity ratio is low, sanitary condition is difficult to guarantee, the quality instability.Analyze its reason, key problem in technology is that the position of needle point and handle limits, and unordered draw point and handle are difficult to adopt mechanization to assemble.The developed country such as the U.S., Japan, Germany, Korea S etc. have realized motorization assembly basically, but what use is pick off, and cost height, speed are slow, and the packaging efficiency of every equipment all is no more than one of per second.
At problem set forth above, the invention provides a kind of finder of disposable venous infusion needle head assembling and the method for assembling thereof, its purpose is to solve and has in the manual operations that productivity ratio is low, unhygienic, the problem of poor product quality, further reduces the cost of relevant import equipment and improves the speed of assembling.
The present invention comes to be realized by the following technical programs:
A kind of finder of disposable venous infusion needle head assembling is characterized in that: have an aperture on the finder, an inclined-plane consistent with infusion needle is set in the aperture.
Finder is provided with holes for clamping.
A kind of method of disposable venous infusion needle head assembling is characterized in that this method is to carry out as follows:
In a, the hole with the inside level insertion of draw point needle point finder;
B, with finder rotation, make draw point to vertical position, in the process of rotation on one side, on one side little vibration;
C, finder step up draw point.The spin orientation device makes draw point to horizontal level;
D, with handle on the rear sleeve of draw point, make the projection on needle point inclined-plane consistent with the handle plane;
E, adjustment finder unclamp draw point, and draw point is withdrawed from finder.
Characteristic of the present invention and innovation part are to utilize concurrent engineering and pneumatic control automatization that needle tubing is carried out orientation and assemble with needle handle, a large amount of not only unhygienic, quality but also unsettled inefficient manual operations have been replaced, the orientation and the assembling mechanism that have replaced the overseas utilization pick off, improved production efficiency, reduced the cost of equipment, adopt technical solutions according to the invention, can reach packaging efficiency is 3 of per seconds, and the apparatus sanitation condition meets 100,000 grades and purifies requirement.Assemble the product percent of pass 100% that rolls off the production line, quality index meets the requirement of YY0028-90 " disposable use venoclysis needle " standard, makes this equipment of China not need import, can also export.
Accompanying drawing 1 is the structural representation of finder of the present invention;
Accompanying drawing 2 is a process chart of the present invention.
The present invention is specifically described by embodiment below in conjunction with accompanying drawing:
The finder 2 of disposable venous infusion needle head assembling has an aperture 5 on it, an inclined-plane consistent with infusion needle 3 is set in the aperture 5.Finder 2 and a drive mechanism link, and can realize rotation; Connect the function that can realize clamping Yu unclamp with a pneumatic mechanism by holes for clamping.
Key problem in technology of the present invention is to close in the position of needle point and handle to fasten.The projection on needle point inclined-plane must be consistent with the plane of handle 4, just the inclined-plane of pin up, the needle point infra, the plane of handle is the position in level, and only in this way, the nurse is when transfusion, needle point better penetrates patient's blood vessel, otherwise is to be difficult to operation.
The method of disposable venous infusion needle head assembling, undertaken by step as shown in Figure 2:
In a, the aperture 5 with the inside level insertion of draw point 1 needle point finder 2; Described horizontal level is not the very strict of requirement, can be relative level;
B, with finder 2 rotation, make draw point 1 to vertical position, in the process of rotation on one side, on one side little vibration; In the process of vibration, because the effect on inclined-plane 3 is defined the position of draw point in finder.C, finder 2 step up draw point 1, and spin orientation device 2 makes draw point 1 to horizontal level; Because the quality of medical care standard is very high to the requirement of needle point, operating like this is to be unlikely when overlapping handle 4 needle point is damaged.D, with handle 4 on the rear sleeve of draw point 1, make the projection on needle point inclined-plane consistent with the handle plane; E, adjustment finder 2 unclamp draw point 1, and draw point 1 is withdrawed from finder 2.
Through such operation, needle point is not have a bit damage at microscopically.
