Description

Intravenous needle fin feeding mode

Technical Field

The invention relates to the technical field of intravenous needle fin assembling equipment in medical instruments, in particular to a feeding mode of intravenous needle fins.

Background

With the improvement of the social living standard, infusion is more widely applied to clinical cases as an important treatment mode. The infusion is a large dose (more than 100ml per administration) of injection infused into the body by intravenous drip, and the infusion is continuously and stably infused into the vein by adjusting the infusion drip speed through an infusion apparatus in the infusion process so as to supplement body fluid, electrolyte or provide nutrient substances.

In the medical infusion industry, disposable infusion sets have been widely used due to the advantages of convenience in use, safety and sanitation. The infusion device does not need to be disinfected during infusion, and a user only needs to unpack the package to connect the infusion device and the intravenous needle together. However, the unclean infusion apparatus can not only weaken the drug effect of the drug, but also possibly cause cross infection, thereby greatly damaging the health of the patient. Therefore, the method has important significance in ensuring the cleanness of the infusion set.

Intravenous needles (also known as plastic needles) are an important component of infusion sets for puncturing the veins of patients and introducing medical fluids into the veins. The existing intravenous needle comprises a needle base, a steel needle and a single blade. For example, chinese patent No. [ patent No. ZL 200820018844.9; the grant publication No. CN201164629Y discloses a venous needle, which comprises a needle body, wherein the front end of the needle body is a needle point inclined plane, a needle handle is arranged on one side of the rear end of the needle body, and the needle handle is positioned on the left side of the rear end of the needle body when the needle point inclined plane faces upwards.

In the prior art, the handle of the vein needle can also adopt a double-blade type, for example, Chinese patent (patent number ZL 200520086804.4; the patent publication No. CN2829755Y discloses a disposable safety intravenous needle, which comprises a needle seat, a needle tip, blades and a needle sleeve, wherein the blades are positioned on two sides of the needle seat.

In order to ensure that the medical instrument (particularly the vein needle wing panel device or equipment used for assembling or assembling the invention) is not manually assembled as much as possible, and the greatest disadvantage of manual operation is that the medical instrument is easy to be attached with germs, so that the sanitary requirement of the product is not qualified; and the assembly speed of manual operation is also low. The medical instrument assembling machine adopts an automatic control mode to carry out automatic assembly, does not pollute products, can ensure that the sanitary index of the products conforms to the national standard, and has higher practical value.

The medical device is usually composed of a plurality of components, and some components need to be installed according to a certain direction, so that deviation can not occur, and the assembled medical device can meet the requirements. However, the mechanism for feeding and transporting the components is generally not provided with a direction-adjusting mechanism for the components, and even if the direction-adjusting mechanism is provided, the direction of the individual components may be incorrect. If the assembly is performed in such an orientation, the product cannot meet the set requirements, and the product is discarded.

For example, chinese patent No. ZL200720113479.5, issued publication No. CN201076644Y discloses an assembling machine for a medical plastic needle assembly, which solves the problems that the existing plastic needles are assembled manually, the assembling mode is inefficient, and the plastic needle assembly is easily contaminated. The device comprises a rotating shaft connected with a motor shaft, a rotating disc which can rotate along with the rotating shaft is fixed on the rotating shaft, a plurality of clamps for fixing workpieces are uniformly distributed on the rotating disc, and three feeders, namely a plastic needle feeder, a filter cap feeder and a sheath feeder, are arranged around the rotating disc.

Obviously, the device also does not disclose a structure for adjusting the mounting direction of the component. The plastic needles in the prior art are generally conveyed by two parallel rails, and although two blocking pieces in the middle of the plastic needle can ensure that the plastic needles are conveyed vertically, the side tubes of the plastic needles are difficult to position, and the side tubes face to the conveying direction or back to the conveying direction, which easily causes the situation that the directions of the plastic needles in a row (i.e. intravenous needle wings) are opposite.

Further, chinese patent No. ZL200710070560.4, CN101152586A, discloses a process and an assembly machine for assembling a plastic needle assembly for medical use, which respectively place a plastic needle, a filter cap, and a sheath in respective feeders, each feeder arranges the accessories placed therein in an array and then sequentially arranges the accessories on respective conveying rails arranged around a turntable, and mounts a roll of filter paper on a filter punching device which is located in the filter cap on the filter cap conveying rail when the filter is punched. Although, it has smooth operation, stable operation, low noise and high automation degree during working. However, the positions of the air outlets of the plastic pins cannot be unified, so that the plastic pins need to be additionally corrected in the assembling process, and the assembling efficiency is low. Similar problems exist with other plastic needle (or intravenous needle) assemblies.

firstly, the vein needle fins 6 are conveyed downwards to the bottom end of a plurality of grooves I101 in a needle handle main board 1, meanwhile, a blowing cylinder 11 is started, a blowing hole 110 on the blowing cylinder 11 is aligned with the grooves I101 in the needle handle main board 1 for blowing, so that the vein needle fins 6 embedded in the grooves I101 slide downwards to the bottom end of the needle handle main board 1 along with airflow and self gravity, and the vein needle fins 6 are blocked in the grooves I101 of the needle handle main board 1 by a row of first thimbles 102 and/or a row of second thimbles 103;

then, the first ejector pins 102 and the second ejector pins 103 are driven to reciprocate up and down along the directions of the corresponding through holes vertical to the axial direction of the corresponding groove I101; when the first thimbles 102 are retracted downwards into the groove I101, and the second thimbles 103 are ejected upwards out of the groove I101, a row of vein needle fins 6 which are blocked by the first thimbles 102 and clamped between the first thimbles 102 and the second thimbles 103 are conveyed downwards along the groove I101, and meanwhile, part of vein needle fins 6 staying on the groove I101 in the row of vein needle fins 6 are conveyed downwards along the groove I101 under the action of the up-and-down and front-and-back reciprocating pushing of a row of baffle needles 201 on the pushing assembly 2; while the following side-by-side intravenous needle wings 6 are blocked by the second needles 103; when the first thimbles 102 are ejected out of the groove I101 and the second thimbles 103 are retracted downwards into the groove I101, the vein needle wing pieces 6 which are subsequently arranged side by side and blocked by the second thimbles 103 are conveyed downwards by the length distance of one vein needle wing piece 6, and are blocked by the first thimbles 102; the first thimble 102 and the second thimble 103 move back and forth in sequence, so that the vein needle fins 6 start to leave the needle handle main board 1 to be conveyed downwards orderly row by row;

meanwhile, the feeding seat 3 is rotationally guided through the driving device 31, so that a plurality of feed inlets II 301 on the feeding seat 3 are aligned with a discharge outlet corresponding to the groove I101 on the needle handle main board 1, and a row of vein needle fins 6 in the needle handle main board 1 are conveyed downwards into the feeding seat 3; the stop slider 320 on the bottom end face of the feeding seat 3 stops the row of intravenous needle wings 6 conveyed in.

Then, the feeding seat 3 is continuously subjected to rotary guiding adjustment through the driving device 31, meanwhile, the material blocking slider 320 on the bottom end face of the feeding seat 3 is removed to convey a row of intravenous needle fins 6 downwards into a falling track of the guiding device, and the intravenous needle fins 6 slide downwards or fall into a row of alternate slotted holes 502 in the intravenous needle fin jig 5 after deflecting and guiding for 0-90 degrees along the falling track of the guiding device;

The vein needle fins 6 are conveyed row by row and sent into the groove V501 in the vein needle fin jig 5 by the sequential and cyclic reciprocating operation, so that the two rows of vein needle fins 6 which are conveyed adjacently and successively correspond to the full load of one vein needle fin jig 5.

Example 4:

based on example 2, as shown in fig. 1, the present invention provides another specific example of the intravenous needle tab loading manner, which comprises the following steps:

the two vein needle fin feeding mechanisms are arranged side by side, the two vein needle fin feeding mechanisms almost keep the same working operation process, the operation time difference of the two vein needle fin feeding mechanisms is controlled to be one unit length time for transferring the vein needle fin jig 5, and the vein needle fin jig 5 is transferred from a falling track discharge port at the bottom end of the former vein needle fin feeding mechanism to a falling track discharge port at the bottom end of the latter vein needle fin feeding mechanism. (note: wherein the two intravenous needle fin feeding mechanisms are divided into a former intravenous needle fin feeding mechanism and a latter intravenous needle fin feeding mechanism according to the time sequence.)

The operation procedure in delivering the intravenous needle wing 6 into the falling trajectory of the guide device is the same as that of embodiment 3; then, aligning and dropping a row of vein needle fins 6 in a dropping track in a guiding device at the bottom end of the previous vein needle fin feeding mechanism into a row of alternate caulking groove holes on a vein needle fin jig 5;

moving the vein needle fin jig 5 by a unit length distance to enable the other row of alternate caulking groove holes of the vein needle fin jig 5 to be aligned with one row of vein needle fins 6 in a falling track in the bottom end guide device of the next vein needle fin feeding mechanism, and simultaneously, dropping the one row of vein needle fins 6 in the falling track in the bottom end guide device of the next vein needle fin feeding mechanism into the other row of alternate caulking groove holes of the vein needle fin jig 5; the complete loading of each caulking hole 502 on the intravenous needle blade jig 5 is achieved. The vein needle fins 6 are conveyed row by row and sent into a groove V501 in the vein needle fin jig 5 by sequential and cyclic reciprocating operation, so that the two rows of vein needle fins 6 which are separated by one unit length time difference on the front and rear vein needle fin feeding mechanisms are fully loaded corresponding to one vein needle fin jig 5.

According to the technical scheme in the embodiment, the pushing assembly 2 is matched with the two groups of ejector pins arranged at the bottom end of the needle handle main board 1 to work, so that the phenomenon that a plurality of vein needle fins 6 stay in the groove I101 of the needle handle main board 1 due to factors such as light dead weight of the vein needle fins 6 is avoided, and the vein needle fins 6 are effectively conveyed neatly, accurately and efficiently; meanwhile, the needle handle main board 1 is obliquely arranged and the feeding seat 3 can be rotationally guided, so that the stroke distance of the vein needle conveying wing piece 6 is greatly reduced, and the size of the occupied space of the equipment device is reduced; the vein needle fin 6 conveyed into the falling track in the guiding device is guided by the guiding device in a rotating and offsetting way through the mutual matching work of the guiding device and the vein needle fin jig 5 arranged at the outlet at the bottom end of the guiding device, and specifically: after the vein needle fin 6 in one row entering from the inlet at the top end of the falling track of the guiding device rotates and deviates by 0-90 degrees in the downward sliding process of the falling track, the vein needle fin slides out from the outlet at the bottom end of the falling track and enters into the slotted eye 502 at intervals on the vein needle fin jig 5. Because the mutual side-by-side overlapping region of at least half the length of the vein needle fin 6 exists between the two adjacent caulking holes 502 on the vein needle fin jig 5, at least two rows of vein needle fins 6 can be accommodated in the vein needle fin jig 5 with the same length, the capacity expansion effect on the vein needle fin jig 5 is realized, the equipment and process cost are not increased, the internal capacity of the vein needle fin jig 5 per unit length (namely the quantity of the vein needle fins 6) is increased, and the capacity efficiency of the vein needle fin 6 assembling equipment is effectively improved.

It is to be emphasized that: the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
