Problems solved by technology

[0004] The existing disposable intravenous infusion needle products basically adopt manual assembly, because the manual assembly speed is slow, the efficiency is low, and the manual is easy to cause secondary pollution, which is not suitable for the development of modern industry
Therefore, it is very necessary to develop the automatic assembly technology of disposable intravenous infusion needle products to replace manual operation, while the automatic assembly process of disposable intravenous infusion needle products needs to overcome the problem of automatic material distribution of needle hub components, especially the double needle handle needle hub Because of its special appearance and shape, it greatly increases the difficulty of batch automatic material distribution

Embodiment 1

[0040] Such as Figure 4 As shown, the needle seat assembly 2 of the double-handle venous needle includes a double-needle handle seat, and the middle part of the double-needle handle seat has a mandrel sleeve 3. In some products, a mandrel can be plugged and fixed in the mandrel sleeve 3, and in some products The mandrel sleeve 3 is not inserted into the mandrel.

[0041] The material distribution method of the needle seat assembly of the double-needle-handle medical venous needle comprises the following steps:

[0042] a. Discharging: place the needle seat assembly 2 in the silo, a feeding trough 4 is arranged on one side of the silo, and output the needle seat assembly 2 from the silo to the input end of the feeding trough 4; step a The silo in the silo can be an ordinary silo or other vibrating devices. Through the vibration of the silo, the needle base assembly 2 in it can be sequentially output. The input end can be directly connected or not connected, and it can be tra...

Embodiment 2

[0052] The general content of this embodiment is the same as that of Embodiment 1, the difference is that in this embodiment, as another solution, the positioning mechanism includes a manipulator, and when the needle hub assembly 2 moves onto the conversion seat 10, the needle The seat assembly 2 is compressed on the conversion seat 10 . The manipulator here can be a common manipulator.

Embodiment 3

[0054] The general content of this embodiment is the same as that of Embodiment 1, the difference is that in this embodiment, as another solution, the intermittent stopper mechanism can also be a combination of several manipulators and sensor-9, through sensor-9 9 Detect the position of the needle base assembly 2, and realize the sequential intermittent output of the needle base assembly 2 through the asynchronous action of the manipulator.

Abstract

The invention provides a separation method and a separation device for needle seat assemblies of a double-needle-handle medical vein needle, and belongs to the technical field of medical equipment. The method and the device solve the technical problems that the needle seat assemblies are low in assembling speed and low in efficiency in the prior art. The separation method comprises the following steps of a, discharge, b, feeding, c, intermittent output, and d, reversing adjustment. The separation device comprises a base, wherein strip-shaped feeding groove bodies used for supporting the needle seat assemblies are fixed on the base; vibrators capable of allowing the feeding groove bodies to generate vibration are arranged between the feeding groove bodies and the base; the needle seat assemblies on the feeding groove bodies can be conveyed forward by the vibration of the feeding groove bodies; strip-shaped pressing strips are fixed on the base, parallel to the feeding groove bodies, and located right above the feeding groove bodies; and gaps capable of allowing the needle seat assemblies to pass through are formed between the pressing strips and the feeding groove bodies. The method and the device have the advantages of high assembling speed, high efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and relates to a material distributing method and a device for a needle seat assembly of a double-handle medical venous needle. Background technique [0002] Disposable intravenous infusion needles have been developed earlier in China, and have been produced at home and abroad for many years, and are now widely used in clinical practice. It is mainly divided into single-handle venous needles and double-handle venous needles. Disposable intravenous infusion needles are composed of protective sleeves, needle tubes, needle handles, hoses, needle hubs, and needle hub protective caps. The product is mainly used in medical units with disposable infusion sets and disposable sterile syringes. It is mainly used for intravenous infusion, blood transfusion or blood collection in clinical practice. [0003] The needle seat assembly of the double-handle venous needle includes a double-needle handle...
