Description

Technical Field

[0001] The utility model relates to the technical field of infusion set feeding equipment, in particular to an infusion set straightening device. Background Art

[0002] Disposable infusion sets are commonly used medical consumables. There are many types of infusion sets, which are usually composed of intravenous infusion needles, needle holders, long catheters, flow regulators, drip buckets, short catheters, and medicine needles. However, when the medicine liquid in ordinary infusion sets begins to enter the drip bucket, it is easy to form a mixture of gas and medicine liquid. The gas-liquid mixture will quickly enter the infusion pipeline below the drip bucket, forming bubbles during infusion, posing a threat to the patient's health. Therefore, automatic exhaust infusion sets have appeared. An exhaust pipe is installed at the lower end of the drip bucket. The top of the exhaust pipe is semi-closed. The exhaust pipe is connected to the medicine needle and the short catheter. This structure avoids the problem of bubbles generated by liquid impact during exhaust and bubbles hidden in the catheter, and truly realizes the automatic exhaust performance of the infusion set without manual inversion of the drip bucket and manual intervention. In order to ensure the hygiene and safety of the medical infusion set, the infusion set needs to be independently packaged and sterilized after assembly and production. Therefore, the requirements for the degree of automation of infusion set packaging are increasing. The medical infusion set is a flexible, linear object, and it needs to be picked up, wound, and transported after winding before packaging.

[0003] After searching, Chinese patent CN212048048U discloses an automatic material-retrieving device for an infusion set, including a frame, a slide rail, a tail material-retrieving mechanism and a head material-retrieving mechanism, wherein the slide rail is fixedly mounted on the top of the frame along the X-axis direction, and the tail material-retrieving mechanism and the head material-retrieving mechanism are slidably mounted on the slide rail; the tail material-retrieving mechanism includes a first material-retrieving mounting profile, a profile longitudinal moving assembly and a profile translation assembly arranged at the upper end of the first material-retrieving mounting profile, and a plurality of groups of tail material-retrieving assemblies arranged at intervals at the lower end of the first material-retrieving mounting profile; the head material-retrieving mechanism includes a second material-retrieving mounting profile, a profile longitudinal moving assembly and a profile translation assembly arranged at the upper end of the second material-retrieving mounting profile, and a plurality of groups of head material-retrieving assemblies arranged at intervals at the lower end of the second material-retrieving mounting profile. The shortcomings of the above patents are as follows:

[0004] First, the above patent straightens the infusion set through the tail material taking mechanism and the head material taking mechanism, but the above patent can only straighten the long catheter of the infusion set, but the existing infusion set not only contains a long catheter, but also a short catheter. The above patent cannot straighten the short catheter, and thus cannot achieve the straightening of the entire infusion set; second, for the infusion set containing an exhaust tube, the end of the drip bucket away from the long catheter also has a short catheter, an exhaust tube, and a medicine needle, with many parts. The short catheters and exhaust tubes of multiple infusion sets are entangled together, which is not only inconvenient to take out materials, but also not conducive to winding operations; third, the short catheter of the existing infusion set is inclined relative to the long catheter, such as the Y-shaped three-way infusion set. For the inclined short catheter, the above patent cannot straighten it. Summary of the invention

[0061] When the flow regulator 6 of the infusion set 3 is close to the needle seat 5, the first clamping jaw 27 of the first straightening mechanism 1 and the second clamping jaw 30 of the second straightening mechanism 2 grab the flow regulator 6 of the infusion set 3 and the long catheter 4 between the drip bucket 8, the first straightening mechanism 1 and the second straightening mechanism 2 move away from each other, the first clamping jaw 27 of the first straightening mechanism 1 presses against the flow regulator 6, and moves the flow regulator 6 close to the needle seat 5, the first clamping jaw 27 of the first straightening mechanism 1 presses against the flow regulator 6, and the outer end of the second clamping jaw 30 of the second straightening mechanism 2 presses against the other end of the long catheter 4, and the long catheter 4 of the infusion set 3 is straightened;

[0062] Step 2: drive the clamping jaws of the third straightening mechanism 7 to grab the flow regulator 6 or the dripping funnel 8, and the width of the space between the two third straightening jaws of the third clamping jaw 17 after closing is greater than the outer diameter of the dripping funnel 8, so that the third clamping jaw 17 can slide through the dripping funnel 8;

[0063] Step 3: Drive the two second straightening claws of the second clamping jaw 30 to open, drive the first clamping jaw 27 to move forward, the front end of the first clamping jaw 27 abuts against the needle seat 5, and the infusion set 3 can be pulled forward as a whole, so that the drip bucket 8 passes through the third clamping jaw 17 forward, that is, at this time, the drip bucket 8 is located at the front end of the third clamping jaw 17;

[0064] Step 4: driving the fourth clamping jaw 20 to approach the third clamping jaw 17, and the fourth clamping jaw 20 grabs the short tube 10;

[0065] Step 5: Drive the fourth clamp 20 to move backward. The fourth clamp 20 moves backward along the short catheter 10 until the rear end of the fourth clamp 20 stops at the part where the rear end of the short catheter 10 is connected to the exhaust pipe 11 and the medicine needle. The rear end of the fourth clamp 20 presses against the exhaust pipe 11 and the medicine needle. The fourth clamp 20 continues to move backward. Because the long catheter 4 has been straightened, and the front end of the first clamp 27 presses against the needle seat 5, the fourth clamp 20 moves backward against the exhaust pipe 11, and cooperates with the first clamp 27 to straighten the short catheter 10.

[0066] There are two methods for adjusting the exhaust pipe of the infusion set to a specified state in the utility model. The specified state can be a downward drooping state or another specified state, such as a horizontal state, which can be set according to needs. One method is to drive the first straightening mechanism 1 to move toward the fourth straightening mechanism 9, or to drive the fourth straightening mechanism 9 to move toward the first straightening mechanism 1, or to drive the first straightening mechanism 1 and the fourth straightening mechanism 9 to move toward each other, so that the infusion set 3 is in a relaxed state and the exhaust pipe 11 droops under the action of its own gravity; drive the first straightening mechanism 1 and / or the fourth straightening mechanism 9 to return to their original positions to ensure that the exhaust pipe 11 remains in a drooping state when the infusion set 3 is in a straightened state; the other method is to drive the exhaust pipe toggle mechanism 12 to make the exhaust pipe 11 away from the short catheter 1. 0 is rotated to a specified state, such as a horizontal state or a drooping state. The two modes can be selected according to the needs. The utility model can also adjust the position of the flow regulator 6. The clamping claw of the regulator position adjustment mechanism 13 clamps the flow regulator 6, drives the regulator position adjustment mechanism 13 and the second straightening mechanism 2 to move toward the first straightening mechanism 1, and adjusts the distance between the flow regulator 6 and the drip bucket 8, so as to adjust the position of the flow regulator 6 on the long catheter 4 according to the packaging requirements. Compared with the prior art, the utility model can realize the straightening operation of the infusion set with the exhaust tube, and can adjust the exhaust tubes to the downward drooping state, so that all the exhaust tubes are in order, thereby further improving the efficiency of the subsequent winding operation.

[0079] The straightening operation steps of the infusion set of the utility model are as follows:

[0080] Step 1: drive the first clamp 27 and the second clamp 30 to grab the three-way long tube 43 of the Y three-way infusion set 42 from the material conveying mechanism, drive the first straightening mechanism 1 to move away from the second straightening mechanism 2, or drive the second straightening mechanism 2 to move away from the first straightening mechanism 1, or drive the first straightening mechanism 1 and the second straightening mechanism 2 to move in opposite directions at the same time,

In the initial state, the angle of the short tube clamping jaw 36 in the short tube straightening mechanism 35 on the front side of the first clamping jaw 27 is adjusted according to the inclination angle of the first short tube 44. The adjusting plate 41 is driven to rotate by adjusting the driving motor 40. The adjusting plate 41 drives the short tube clamping jaw driving cylinder 37 to rotate, thereby changing the inclination angle of the short tube clamping jaw 36. After the three-way long tube 43 is straightened, the short tube clamping jaw 36 opens and can just grab the first short tube 44. Then, the short tube clamping jaw driving moving assembly is driven to drive the first short tube 44 to move away from the first clamping jaw 27 until the front end of the short tube clamping jaw 36 abuts against the needle seat at the front end of the first short tube 44, and the first short tube 44 is straightened.

[0085] Step 4: Straighten the second short tube 45: drive the short tube straightening mechanism on the rear side of the second clamp 30, open the short tube clamp, grab the second short tube, and the short tube clamp drives the moving assembly to drive the second clamp 30 to move backward along the second short tube 45 until the short tube clamp abuts against the fixing seat at the rear end of the second short tube 45, and the second short tube 45 is straightened; the utility model is not only suitable for straightening conventional infusion sets, but also suitable for straightening Y-way infusion sets, which greatly broadens the scope of application of the utility model.
