Hereinafter, embodiments of the present utility model will be described in detail with reference to the accompanying drawings.

Examples

Referring to fig. 1, the present embodiment provides a dosing needle, including:

a handle 1, the interior of which is provided with a lumen 110;

needle heads 2 are respectively arranged at two ends of the handle 1, and the two needle heads 2 are communicated with the tube cavity 110;

a flexible sleeve 3 sleeved outside each needle 2; the inner ends of the two flexible sleeves 3 are respectively connected with the two ends of the handle 1, and the outer ends of the flexible sleeves 3 are closed.

Wherein the outer end refers to the end remote from the centre point of the handle 1, i.e. the upper and lower ends as shown in figures 1 and 2. Whereas the inner end refers to the end near the centre point of the handle 1. The drug adding needle of the embodiment is provided with a handle 1 at the middle part, and a hollow tube cavity 110 is arranged in the handle. The two ends of the handle 1 are respectively connected with the needle head 2, the inside of the needle head 2 is provided with a hollow channel, and the channel communicates with the cavity 110 for the circulation of liquid medicine and air. The needle heads 2 connected with the two ends of the handle 1 are respectively and completely wrapped in the flexible sleeve 3, and the flexible sleeve 3 is made of silica gel. The outer ends of the two needles 2 are provided with needle points, and can pierce the closed outer ends of the flexible sleeve 3.

Referring to fig. 2, in the drug adding needle of the present embodiment, when a patient dispenses a drug, for example, when the powder to be dispensed in the drug bottle 6 is mixed and mixed into the drug solution to be infused in the infusion bag 5, the following steps are required:

step one, placing an infusion bag 5 above, holding a handle 1 by a medical staff, and puncturing the needle 2 above by the closed end of a flexible sleeve 3 outside the needle; continuing pushing the needle head 2, enabling the needle head 2 to penetrate out of the flexible sleeve 3 and puncture the sealing plug of the infusion bag 5 through the expansion and contraction of the flexible sleeve 3, and inserting the needle head 2 into the liquid medicine to be infused in the infusion bag 5;

step two, placing the medicine bottle 6 below, and puncturing the needle 2 below by the closed end of the flexible sleeve 3 outside the medicine bottle; continuing pushing the needle head 2, the needle head 2 pierces the bottle stopper of the medicine bottle 6 and is inserted into the medicine bottle 6 through the extension and retraction of the flexible sleeve 3; at this time, since the medicine bottle 6 containing the medicine powder to be dispensed in the prior art is generally in a negative pressure state, the medicine liquid to be dispensed in the upper infusion bag 5 is sucked into the medicine bottle 6 under the negative pressure effect in the medicine bottle 6, and the medicine bottle 6 is generally an antibiotic medicine bottle, so that the medicine powder to be dispensed and the medicine liquid to be dispensed are mixed and dissolved under the conditions of not contacting with external air and avoiding being polluted to form the medicine liquid to be dispensed;

step three, the dosing needle of the embodiment is turned upside down, namely, the medicine bottle 6 is placed above, so that the needle head 2 in the medicine bottle 6 is positioned in the liquid to be dosed; placing the infusion bag 5 below so that the needle 2 in the infusion bag 5 is positioned in the air above the liquid medicine to be infused; then pinching the infusion bag 5 to enable air in the infusion bag 5 to be squeezed into the medicine bottle 6 through the medicine adding needle so as to increase the air pressure in the medicine bottle 6, so that the medicine to be dispensed in the medicine bottle 6 is pressed into the infusion bag 5 through the medicine adding needle, and the medicine to be dispensed in the medicine bottle 6 is mixed and matched into the infusion bag 5. If multiple kinds of liquid medicine are prepared, the needle head 2 at the end of the medicine bottle 6 is only required to be pulled out, the flexible sleeve 3 is used for sleeving the needle head 2 in the medicine bottle again under the elastic action of the flexible sleeve, and then the steps are repeated.

And step four, after the medicine dispensing is finished, the two needles 2 are respectively pulled out of the infusion bag 5 and the medicine bottle 6, so that the airtight medicine dispensing for preventing the needles 2 and the medicine from being polluted by the outside and preventing the needles 2 from stabbing medical staff is realized.

It can be seen that the dosing needle of this embodiment is provided with a handle 1, which is convenient to take and use. The two ends of the handle 1 are respectively provided with the needle heads 2, and the two needle heads 2 are respectively used for penetrating the infusion bag 5 and the medicine bottle 6, namely, the two needle heads 2 can finish the medicine preparation by performing one-time penetrating operation respectively, so that pollution or stabbing of medical staff caused by repeated penetrating of the needle heads 2 through the infusion bag 5 is avoided; and two needles 2 are respectively sealed in the flexible sleeve 3, and after the needles 2 are pulled out from the plug body, the flexible sleeve 3 can automatically reset and wrap the needles 2, thereby being beneficial to avoiding the needles 2 and medicines from being polluted by the outside or injuring medical staff by mistake.

Referring to fig. 1 and fig. 2 in combination, specifically, the handle 1, the needle 2, and the flexible sleeve 3 are all configured as round tubes, and the central axes of the three are coincident. The flexible sleeve 3 is provided as a resilient, telescopic silicone sleeve. The flexible sleeve 3 may be a transparent sleeve.

In some embodiments, the outer parts of the flexible sleeves 3 are respectively sleeved with a protective sleeve 4, the inner ends of the two protective sleeves 4 are respectively connected with the two ends of the handle 1, and the outer ends of the protective sleeves 4 are closed. The protective sleeve 4 can further protect the flexible sleeve 3 and the needle 2, and the flexible sleeve 3 is prevented from being extruded by false collision and is pierced by the needle 2.

The protective sleeve 4 may in particular be provided as a plastic tube, for example a rigid plastic tube. The hardness of the protective sleeve 4 is greater than the hardness of the flexible sleeve 3. The protective sleeve 4 is provided as a circular tube, for example as a transparent sleeve. The protective sleeve 4 is arranged with the flexible sleeve 3 with the central axis coinciding.

In the dosing needle of this embodiment, when dispensing a dose to a patient, the protective sleeve 4 outside the flexible sleeve 3 of the needle 2 is removed, and then the needle 2 pierces the closed end of the flexible sleeve 3 outside the needle for subsequent use.

Can specifically be provided with the external screw thread respectively at the both ends of handle 1, be provided with the internal screw thread respectively on the inner wall of protection sleeve 4, the inner of two protection sleeve 4 is connected with the both ends screw thread of handle 1 respectively to the installation or the dismantlement of protection sleeve 4 and handle 1 are convenient for. When dispensing medicine to patients, the protection sleeve 4 is only required to be rotated firstly to remove the threaded connection with the handle 1, so that the operation is convenient, and the time and the labor are saved.

It may also be specifically that two ends of the handle 1 are respectively provided with a raised screw seat 120, a hollow channel is arranged in the screw seat 120, and the channel is communicated with the lumen 110; the outer wall of the screw seat 120 is provided with external threads, and the inner ends of the two protection sleeves 4 are respectively connected with the two screw seats 120 in a threaded manner, so that the protection sleeves 4 are conveniently connected with the two ends of the handle 1 through the screw seats 120.
