1. Field of the Invention
The present invention is related to a syringe cap removing device, more especially to a removing device which clamps the syringe cap.
2. Description of the Prior Art
Medical workers touch and use plural syringes everyday, so they are in danger of infection by needle pricking. Thus, a used syringe needle should be covered by a cap and be removed form the syringe. However, the needle is extremely thin, and the opening of the cap is also tiny. As a result, it is difficult to insert the needle into the cap.
To prevent needle pricking, a clamping device can position the cap, and the user can hold the syringe to insert the needle into the cap without holding the cap by hand. As disclosed in patents TW 312155 and TW 363423, the clamping device is held with one hand, and the syringe is held with the other hand. That is, the device is unable to be use with a single hand. Patent TW 479524 disclosed a device which is able to be positioned on a table or others, so the device is possibly used with a single hand. However, the direction of the clamping portion can be adjusted limitedly. In addition, to release the cap into a collecting container, the seat with the clamping device has to be removed from the table.
The main object of the present invention is to provide syringe cap removing device having a clamp which is able to be positioned on a seat or to be held by hand directly.
To achieve the above and other objects, syringe cap removing device, including a seat, a main body, and a clamp.
An end of the main body is detachably disposed on the seat. An end of the clamp is disposed on an end of the main body opposite to the seat. The clamp defines a clamping space for clamping a syringe cap.
Thereby, the removing device of the present invention can be positioned on a table or a rack, or be detached for held by hand. Thus, the clamp can grasp the syringe cap so that a user can remove the syringe needle from the syringe to keep the needle in the cap. And then, the clamp is released at an appropriate place for collecting the cap and the needle. As a result, the cap and the needle may not be touched by the user so as to prevent infection.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.

In the present embodiment, the seat 10 includes a base 11, a stand 12, and a support element 13. The base 11 has positioning mechanisms to be positioned on a table, to a periphery of table, on a rack or others. The stand 12 is disposed on the base 11. The support element is detachably disposed on an end of the stand 12 opposite to the base 11. Specifically, the base 11 has a first through hole 111. The stand 12 is rod-shaped to insert through the first through hole 111 and is positioned at the first through hole 11 by a first fastening element 112.
The main body 20 is detachably disposed on the seat 10 with an end thereof. In the present embodiment, the main body 20 is detachably disposed on the support element 13. More specifically, the support element 13 has a second through hole 131. The main body 20 is rod-shaped to insert through the second through hole 131 and is positioned to the second through hole 131 by a second fastening element 132. The clamp 30 is disposed on an end of the main body 20 opposite to the seat 10.
The clamp 30 defines a clamping space to receive the cap 43 of the syringe 40 and to clamp it. In the present embodiment, the clamp includes a base portion 31 and two clamping arms 32. The base portion 31 is disposed on the main body 20. Each clamping arm 32 has a pressing portion 321 and a clamping portion 322 at two opposite ends thereof. The clamping space is enclosed by the two clamping portion 322. Each clamping arm 32 is pivotally disposed on the base portion 31. The connection between the clamping arm 32 and the base portion 31 is located between the pressing portion 321 and the clamping portion 322. The two clamping arms 32 are located at two sides of the base portion 31, and each clamping arm 32 is pushed by an elastic element 33. The elastic element 33 is located between the pressing portion 321 and the connection between the clamping arm 32 and the base portion 31 so that the two clamping portions 322 tend to approach each other. Specifically, each clamping portion 322 includes a cambered face 3221. The two cambered faces 3221 face each other. The clamping space is defined between the two cambered faces 3221. An axial direction is defined by the clamping space. Each cambered face 3221 is formed with a plurality of elongated ribs or grooves arranged spacedly. Each elongated rib or groove has a longitudinal direction parallel to the axial direction. Due to the elongated ribs or the grooves, friction is increased for positioning the cap 43 of the syringe 40. Preferably, in a normal state, the clamping space is substantially equal to or slightly smaller than the size of the cap 43. Thereby, the cap 43 can be positioned to the clamping space without pressing the pressing portion 321.
More practically, the main body 20 is formed with two contacting faces 21 opposite to each other at an end thereof opposite to the seat 10. The base portion 31 has a through 311 for sleeved onto the main body 20 to cover the contacting faces 21. The base portion 31 is screwed with the main body 20. The two contacting faces 21 are recessed relative to other portion of the main body 20 so that a stepped face 22 is formed at an end of each contacting face 21 neat the seat 10 wherein the stepped face 22 is perpendicular to the contacting face 21. The two stepped faces 22 are adapted for being abutted against by the base portion 31 to prevent the base portion 31 from pivoting with respect to the main body 20. The base portion 31 is substantially U-shaped and has a pivot portion 312 for connecting to the two clamping arms 32 at an end opposite to the trough 311. Each clamping arm 32 has an extending arm 323 which extends from a side of the clamping arm 32 facing the base portion 31. The two extending arms 323 overlap the pivot portion 312 of the base portion 31. A pivot pin 34 is inserted through the pivot portion 312 and the two extending arms 32. A first direction is defined as a direction from the opening of the trough 311 to the pivot portion 312. The axial direction of the clamping space is substantially perpendicular to the first direction. Besides, a blocking element 35 is arranged below the base portion 31 and the two clamping arms 32. The blocking element 35 has a blocking portion 351. The blocking portion 351 is right under the clamping space to be abutted against by a tip of the cap 43 to prevent it from falling down.
In the present embodiment, the bottom of the trough 311 abuts against the lateral face of the main body 20 to make the main body 20 insert through the trough so that the axial direction of the clamping space is parallel to the longitudinal direction of the main body 20. As a result, the clamp 30 and the main body 20 are L-shaped. However, as shown in
In use, the seat 10 can be positioned on a table, a rack, or other places, and the main body 20 is positioned on the seat 10, as shown in
Also, the present invention can be held by hand. Please refer to
