detailed description

As shown in Figure 1, the utility model provides a sharps barrel, comprising: a barrel body 1 for recovering infusion needles; a barrel cover 2 covered on the barrel body 1; cutting device. In the utility model, the cutting device is hidden in the barrel body 1, and the infusion hose can be cut off without external scissors, which saves the trouble of finding external scissors.

As shown in Figure 1, an insertion slot 11 is provided on the barrel wall of the barrel body 1. The infusion needle and the infusion hose to be separated are inserted into the barrel through the insertion slot 11, and the infusion needle and the infusion hose can be separated by the action of the cutting device. The tube is cut and separated, so that the infusion needle falls into the barrel body 1 under the action of gravity, avoiding contamination or hand injury caused by operation outside the barrel body 1 .

The cutting device of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Embodiment one

As shown in Figures 2a and 2b, the cutting device includes: a cutter 4 located in the barrel body 1, used to cut and separate the infusion hose and the infusion needle; a drive mechanism that is connected and drives the cutter 4 to move; The infusion needle support seat 3 inside. When the cutting knife 4 applies a cutting force to the infusion hose, the support seat 3 is used to support the infusion hose and provide it with a reverse force of the cutting force, so as to quickly cut off the infusion hose.

Specifically, as shown in Figures 2a and 2b, the supporting seat 3 is stably installed in the bucket body 1 through reinforcing ribs 5 to improve the supporting strength. As shown in FIG. 4 , the support base 3 has an infusion needle guide channel 30 , and the guide channel 30 communicates with the insertion slot 11 opened on the barrel wall of the barrel body 1 . When the infusion needle and the infusion hose to be separated enter the barrel body 1 from the insertion slot 11, they can move in the barrel body 1 along the guide passage 30 communicating with the insertion slot 11, so that the infusion needle to be separated and the infusion hose are accurately placed in the cuttable position of the cutter 4. Specifically, as shown in Figure 4, the guide channel 30 is formed by two opposite channel walls 31 and 32, and the channel wall 31 is provided with a cut-in slot 3a connected with the guide channel 30, and the channel wall 32 is provided with The cut-out slots (not shown) through which the guide channel 30 runs through, when the cut-in slots 3a on the channel wall 31 and the cut-out slots (not shown) on the channel wall 32 communicate with the guide channel 30 , forming the cutting channel of the cutter 4. As shown in Figures 2a and 2b, when the infusion needle and the infusion hose to be separated are placed in the guide channel 30 and the infusion hose is exposed to the cutting knife 4 from the cutting hole 3a, the driving mechanism drives the cutting knife 4 along the The cutting channel makes a cutting movement, thereby cutting off the infusion hose.

As shown in Figure 2a, the driving mechanism is a manual driving mechanism. The manual drive mechanism is installed on the barrel cover 2, and the manual drive mechanism includes: a pressing slider 41 connected to the cutter 4 and extending to the outside through the barrel cover 2; set in the barrel cover accommodation space 21 and sleeved on the pressing slider Return spring 42 on 41; wherein, the top of pressing slide block 41 is provided with the block 43 that is positioned at bung accommodating space 21; One end of return spring 42 contacts block 43, and its other end contacts bung accommodating space 21 of the lower barrier wall 21a.

The working principle of the manual drive mechanism is: place the infusion needle and the infusion hose in the guide channel 30 and expose the infusion hose to the cutting channel, apply downward pressure on the top of the pressing slider 41, under the action of the pressure, The return spring 42 is compressed, and the pressing slider 41 drives the cutter 4 connected to it to move down along the cutting channel, thereby cutting off the infusion hose straddling the cutting channel. When the downward pressure applied to the top of the pressing slider 41 disappears, the restoring force of the return spring 42 is applied to the stopper 43 , prompting the pressing slider 41 to drive the cutter 4 to return.

In order to make the guide channel 30 have an accurate guiding function, in this embodiment, the guide channel 30 has a shape adapted to the infusion needle and the infusion hose. As shown in Figures 2a and 4, the guide channel 30 includes: a circular channel 30a in the middle for the passage of the infusion hose; and flat channels 30b located on both sides of the circular channel 30a for the passage of the ears of the infusion needle. Flat channels 30b are provided on both sides of the circular channel 30a, which can be adapted to both the infusion needle with two ears and the infusion needle with one ear.

As shown in Figures 2a and 2b, the cutting edge of the cutting knife 4 in this embodiment is a serrated edge and is inclined, which effectively increases the cutting contact area and improves the cutting efficiency.

Embodiment two

As shown in Figures 3a and 3b, the cutting device includes: a cutter 4 located in the barrel body 1, used to cut and separate the infusion hose and the infusion needle; a driving mechanism that is connected and drives the cutter 4 to move; The infusion needle support seat 3 inside. When the cutting knife 4 applies a cutting force to the infusion hose, the support seat 3 is used to support the infusion hose and provide it with a reverse force of the cutting force, so as to quickly cut off the infusion hose.

The structure of the supporting seat 3 in this embodiment is the same as that in the first embodiment.

The driving mechanism is an electric driving mechanism. In addition to the entire structure of the above-mentioned manual drive mechanism, the electric drive mechanism also includes: a motor; a cam connected to the motor drive shaft and in contact with the top of the pressing slider 41, the cam has a protruding portion and a non-protruding portion opposite to the protruding portion; A position sensor (not shown) for detecting the position of the infusion needle.

The working principle of the electric drive mechanism is: when the infusion needle and the infusion hose are not inserted into the guide channel 30, the non-protruding part of the cam contacts the top of the pressing slider 41, and at this time, under the restoring force of the return spring 42, the cutting Knife 4 is located above the cutting passage; when the infusion needle and the infusion hose are placed in the guide passage 30, the position sensor detects that the infusion hose is exposed in the cutting passage, the motor is switched on, and the motor drive shaft drives the cam to rotate. During the process that the contact point on the top of the pressing slider 41 is gradually transferred from the non-protruding part to the protruding part, the pressing slider 41 drives the cutter 4 connected to it to move down along the cutting channel, straddling the infusion hose in the cutting channel is cut off, and the return spring 42 is compressed at this time. During the process that the top contact point between the cam and the pressing slider 41 is gradually transferred from the protruding part to the non-protruding part, the restoring force of the return spring 42 is applied to the stopper 43, so that the pressing slider 41 drives the cutter 4 to return.

The cutting edge of the cutting knife 4 in this embodiment is a flat edge and is arranged horizontally. Driven by the motor, the flat blade cutter 4 can quickly cut off the infusion hose.

Although the above-mentioned utility model has been described in detail, the utility model is not limited thereto, those skilled in the art can modify according to the principle of the utility model, therefore, all the various modifications carried out according to the principle of the utility model should It should be understood as falling into the protection scope of the present utility model.
