Detailed Description

For a better understanding of the technical content of the present utility model, specific examples are set forth below, along with the accompanying drawings.

Referring to fig. 1-3, a sharp instrument barrel for cutting off an infusion needle comprises a sharp instrument barrel body 1, a guide bucket 2, a bearing plate 3, a support plate 4, a guide rod 5, a reset spring 6 and a cutting knife 7.

Infusion needle holding mechanism

The sharp-pointed barrel 1 is a container for collecting an infusion needle of an injector, and is generally of a cylindrical structure with one end open, an opening is arranged at the top end by default, and when the sharp-pointed barrel 1 is full of sharp-pointed objects collected in the sharp-pointed barrel 1, the collected sharp-pointed objects can be poured out of the sharp-pointed barrel 1 through an open discharge opening.

Further, the top end cover of the discharge opening is provided with a cylinder cover 11 for sealing the discharge opening when the sharp instrument collected inside the sharp instrument cylinder body 1 is not required to be discharged, so that the phenomenon that the sharp instrument collected inside the sharp instrument cylinder body 1 is inclined due to the inclined phenomenon is avoided, and the use safety and stability are improved.

Specifically, a silica gel anti-slip pad is adhered and fixed at the bottom of the sharp instrument cylinder body 1; the anti-slip device has good anti-slip effect, so that the sharp machine cylinder body 1 is placed on a tabletop, and is more stable to place on the tabletop due to the fact that friction force is generated between the sharp machine cylinder body and the tabletop through the silica gel anti-slip pad when the sharp machine is used for collecting sharp machines.

Infusion needle cutting mechanism

As shown in fig. 1 and 2, the guide hopper 2 is disposed on the cylinder cover 11, integrally formed with the cylinder cover 11, and two ends of the guide hopper 2 are both in an open structure, a first end is provided with a feed inlet, and a second end is provided with a discharge outlet.

Wherein, the feed inlet is laid along sharp ware section of thick bamboo barrel 1's direction of height perpendicularly, and the discharge gate is laid along sharp ware section of thick bamboo barrel 1's width direction level, and the cross-section of feed inlet and discharge gate is circular, has the passageway that supplies the transfusion needle to wear to establish between feed inlet and the discharge gate, and the cross-section of feed inlet is greater than the cross-section of discharge gate, makes the passageway internal diameter of feed inlet to discharge gate reduce gradually.

The guide rod 5 penetrates through the cylinder cover 11 from top to bottom and extends into the sharp machine cylinder body 1, and the bottom end of the guide rod is detachably connected with the cutting knife 7.

Further, define and cut out cutter 7 and be located the discharge gate top and be first position, be located the discharge gate below and be the second position, so, insert guide fill 2 from the feed inlet when the transfusion needle, and stretch into to the direction of discharge gate along the passageway of guide fill 2 inside from the feed inlet, until the transfusion needle runs through the discharge gate, when extending to the outside of guide fill 2, because of the discharge gate lays along sharp a section of thick bamboo barrel 1's width direction level, the transfusion needle level that extends to the discharge gate outside exposes directly under cut out cutter 7, as shown in fig. 2, the staff holds guide bar 5 and presses guide bar 5 fast perpendicularly downwards at this moment, can drive the cut out cutter 7 of guide bar 5 bottom and cut out the transfusion needle that extends to the outside of discharge gate through cut out cutter 7 and cut out, accomplish the cut out separation of transfusion needle and transfer line by first position.

Specifically, the section of the feed inlet is larger than that of the discharge outlet, so that the inner diameter of a channel from the feed inlet to the discharge outlet is gradually reduced, on one hand, the guide function is realized when the infusion needle is worn, on the other hand, the situation that the cut infusion needle is ejected out of the sharp instrument barrel body 1 when the infusion needle is cut can be avoided, and the cutting safety of the infusion needle is improved.

Bearing plate

In order to ensure that the infusion needle can be cut and separated once by the cutting knife 7, in an alternative embodiment, a supporting plate 3 for horizontally supporting the infusion needle part exposed outside the discharge hole is fixedly arranged under the guide hopper 2, the supporting plate 3 is arranged in parallel with the discharge hole, and the tail end extends to the position under the cutting knife 7.

So, insert guide funnel 2 from the feed inlet when the transfusion needle, and run through the discharge gate along the inside passageway of guide funnel 2 from the feed inlet, when extending to the outside of guide funnel 2, the transfusion needle part that extends the discharge gate exposes on the carrier plate 3, held by carrier plate 3, and the level is located and cuts the cutter 7 directly under, as shown in fig. 2, the staff holds guide bar 5 and presses guide bar 5 perpendicularly downwards fast at this moment, drive the cutter 7 through guide bar 5 and cut off the transfusion needle that will extend to the outside level of discharge gate and expose on carrier plate 3, compare in unsettled naked transfusion needle, cut the cutter 7 and cut the effort to the perpendicular of transfusion needle more accurate, can guarantee that the transfusion needle is cut off by cutter 7 once only, the separation is effectual, it is efficient to cut.

Reset mechanism for cutting knife

As shown in fig. 1 and 2, a support plate 4 is arranged at the top end of the interior of the sharp-pointed barrel body 1, a guide rod 5 is provided at the tail end of the support plate 4 to pass through a through hole 401, a blind hole 402 is provided at the outer side of the through hole 401, a return spring 6 is sleeved at the outer side of the guide rod 5 between the barrel cover 11 and the support plate 4, and end covers 61 are respectively arranged at the top end and the bottom end of the return spring 6.

Further, the end cover 61 at the top end is fixedly connected with the guide rod 5, and the end cover 61 at the bottom end is clamped and fixed at the inner side of the blind hole 402; when the staff holds the guide bar 5 and moves downwards, as shown in fig. 2, the movement of the guide bar 5 can drive the top end cover 61 fixed on the guide bar 5 to move downwards, the reset spring 6 between the two end covers 61 is compressed, the reset spring 6 is a spiral spring and has good elastic pressure, the reset spring automatically restores to the initial state after losing the action of external force, so, after the cutting knife 7 cuts the infusion needle, the staff releases the guide bar 5, the reset spring 6 loses the pressing of external force, and the rebound can automatically upwards rebound by means of the rebound of the reset spring, thereby driving the guide bar 5 to move upwards for reset, and further driving the cutting knife 7 to restore to the initial position.

The initial state of the cutting blade 7 is shown in fig. 1, and the cutting state is shown in fig. 2.

In another embodiment, since the cutting knife 7 is a wearing part, the cutting knife 7 may not be sharp after a period of use, and the cutting and separating requirement of the infusion needle cannot be met, so the cutting knife 7 and the guide rod 5 are in a detachable connection structure; the new cutting knife 7 is convenient to disassemble, assemble and replace in later period, and in particular, a threaded connection mode can be adopted.

In addition, a transparent visual window 111 is provided on the barrel cover 11, as shown in fig. 3, so as to facilitate observation of the insertion position of the infusion needle in the guide funnel 2.

While the utility model has been described with reference to preferred embodiments, it is not intended to be limiting. Those skilled in the art will appreciate that various modifications and adaptations can be made without departing from the spirit and scope of the present utility model. Accordingly, the scope of the utility model is defined by the appended claims.
