Description

Medicine tank

The present invention relates to a medicinal liquid tank, in particular to a medicinal liquid tank that can be used to assist a non-linear safety injection needle to penetrate deeply and thoroughly withdraw the medicinal liquid, so as to avoid the residual liquid.

In clinical medicine, the drug delivery system can be divided into oral, smear, drip, injection and other methods. Among them, the injection drug delivery system injects the liquid into the human body through a syringe, which has better rapid effect and convenience, which is suitable for the current medical process. The most common medical practice is that the syringe includes an injection barrel (12), an injection needle (1) that is connected to the outlet end of the injection barrel (12) with a sleeve (11), and a set of injection barrels ( 12) The injection plunger (13) that can be pushed and pulled, please refer to Figure 1. It mainly uses the pull back of the injection plunger (13) to transfer the liquid medicine through the injection needle (1) and its injection port (10) After the liquid medicine in the bottle (14) is drawn, push the injection plunger (13) back into the injection cylinder (12), and the medicine in the injection cylinder (12) can be passed through the injection needle (1) The injection port (10) is sent out; and the liquid medicine bottle (14) contains a soft stopper (17), the top of the medicine bottle (14) is provided with a necking opening (15), and the necking opening (15) is The soft stopper (17) is closed to avoid the loss or deterioration of the liquid medicine. The soft stopper (17) allows the injection needle (1) and its injection port (10) to penetrate deep into the liquid medicine bottle (14) to draw the liquid medicine. Wherein, the bottom (16) of the liquid medicine bottle (14) is a horizontal plane. When the injection needle (1) draws liquid medicine through its injection port (10), the medicine liquid bottle (14) must be tilted 80 degrees to inject The port (10) is placed on the inner side of the liquid medicine bottle (14) and the corner of the bottom (16) to divert and collect the liquid medicine to provide the injection port (10) for extraction, so as to avoid the medicine liquid remaining in the medicine bottle (14). ) Forms residual medicine, so the operation is more troublesome.

According to the conventional syringe, except for the non-circular rear end of the injection barrel (12), the rest of the parts are round. When placed on a flat surface, due to the influence of gravity, the injection barrel (12) will be The non-circular part at the end is the axis of rolling phenomenon, which causes damage or injury to the human body by falling from a height. The reason is that the injection needle (1) is linear and circular; When in use, the injection needle (1) is located at the front end of the syringe. Therefore, in a busy medical working environment, when holding the syringe, a slight carelessness will stab yourself or hurt others. The reason is The injection needle (1) is located at the foremost end of the syringe; furthermore, the injection of the liquid medicine is required by the medical condition to invasively inject the liquid medicine into the human skin, muscles, or blood vessels. Medical work is complicated. Medical personnel often operate syringes while narrating important matters to others. With multi-tasking, they may over-pierce the injection needle (1) into the skin, muscles, or blood vessels of the recipient, causing human injury , And even cause medical disputes. The reason is that the injection needle (1) is straight, and there is no restriction on the travel distance during injection.

To this end, the applicant aims at the lack of use of conventional injection needles, and provides a safety injection needle, which has been approved to be listed as the invention patent No. I669140. The safety injection needle (2) is constructed with a rewinding structure. The injection needle (2) is combined with an injection syringe (22). The injection syringe (22) is sleeved with an injection push rod (23). The revolving structure is extended forward from the center of the sleeve (21) for a short section to become a The base section (201), the front end of the base section (201) extends laterally to one side for a short section to become a transverse section (202), and the outer end of the transverse section (202) extends straight forward to become a first straight section (203), the front end of the first straight section (203) turns backward to become a first winding end (204), and the front end of the first winding end (204) extends straight backward for a section to become a second straight Section (205), the front end of the second straight section (205) turns forward to become a second rewinding end (206), and the front end of the second rewinding end (206) extends straight forward for a section to become A third straight section (207), the third straight section The front end of (207) is an injection port (20), and the position of the injection port (20) is lower than the first revolving end (204). The third straight section (207) can be located on the same straight line as the base section (201). The second straight section (205) can be located on the same straight line as the base section (201). Accordingly, because the safety injection needle (2) is non-straight, it will not roll when placed, and at the same time, when it is about to stab a person or is about to pierce excessively, it can be touched by the first winding end (204) To the surface of the skin of the person receiving the injection, the safety injection needle (2) is protected against injury or excessive penetration.

but! After the applicant proposed to expose the safety injection needle, the safety injection needle continued to be studied. Among them, the liquid medicine bottle (14) used to provide the safety injection needle (2) to extract the liquid medicine was found to be unsatisfactory in use by the applicant. It is necessary to further develop and innovate it to meet the use of safe injection needles (2) and conventional general injection needles (1), in order to improve the function of the liquid bottle. The general liquid bottle (14) is used in the safety injection needle (2) There are deficiencies such as the following:

1. When the height of the liquid medicine bottle (14) is equal to the height of the second straight section (205) of the safety injection needle (2), please refer to the figure 2 for the medical staff to facilitate the extraction of liquid medicine In actual use, the liquid medicine bottle (14) is usually placed on a flat surface, the injection plunger (23) is pulled back with one hand, and the injection plunger (22) is held with the other hand, and the injection is safe The third straight section (207) of the needle (2) and the injection port (20) are pierced from the soft stopper (17) of the medicine bottle (14) deep into the medicine bottle (14), and the injection The port (20) draws liquid medicine, yes! Since the necked opening (15) of the liquid medicine bottle (14) will block and limit the second rewinding end (206) of the safety injection needle (2), the injection port (20) cannot reach the medicine. The bottom (16) of the liquid bottle (14) is suspended in the liquid medicine bottle (14), resulting in the residual liquid in the liquid medicine bottle (14), which becomes residual medicine, causing waste. The reason is the liquid medicine The necked opening (15) of the bottle (14) blocks the second rewinding end (206) of the safety injection needle (2), so that the injection port (20) of the safety injection needle (2) cannot touch the liquid medicine bottle ( Caused by the bottom (16) of 14).

2. When the height of the liquid medicine bottle (14) is lower than the height of the second straight section (205) of the safety injection needle (2), please refer to Figure 3, although the medicine liquid bottle (14) The third straight section (207) and injection port (20) of the safety needle (2) can be pierced deeply from the soft plug (17), and the bottom of the liquid medicine bottle (14) is touched by the injection port (20) (16) Extract the liquid medicine, but! However, it is impossible for medical personnel to place it on a flat surface for operation. Instead, the injection plunger (23) must be pulled back with one hand, and the injection plunger (22) and the liquid bottle (14) must be held with the other hand, resulting in operation The above is extremely troublesome and inconvenient, especially because the safety injection needle (2) is formed by adopting a rewinding structure extension, the whole body is larger and even more noticeable. The reason is that the liquid medicine bottle (14) and the safety injection needle (2) ) Due to the height difference of the second straight section (205).

3. When the height of the liquid medicine bottle (14) is equal to the height of the second straight section (205) of the safety injection needle (2), since the bottom (16) of the liquid medicine bottle (14) is a horizontal plane, In order to avoid the residual liquid in the liquid medicine bottle (14), the medical personnel must tilt the liquid medicine bottle (14) at 80 degrees and divert the liquid medicine to the inner side and bottom of the medicine liquid bottle (14). (16) is a corner for extraction from the injection port (20), but the liquid medicine bottle (14) is fastened against the second straight section (205) of the safety injection needle (2), and because of the liquid medicine The bottle (14) and the second rewinding end (206) of the safety injection needle (2) block each other. Therefore, the liquid medicine bottle (14) cannot be tilted at all. The reason is that the liquid medicine bottle ( The bottom (16) of 14) is horizontal.

The known liquid bottle (14) is limited to the function of avoiding the loss or deterioration of the liquid, and is only suitable for the general linear injection needle (1) to withdraw the liquid, but it cannot be used to improve the safety of the non-linear injection needle (2) ), and it is easy to cause the drug solution to remain as a residual drug, which increases the waste of the drug solution and phytotoxicity pollution. In some special drug solutions, it is not only expensive, and sufficient doses must be injected. Residual drugs may cause insufficient injection volume. , It should not happen.

Therefore, it is necessary to develop a safe injection needle with a non-linear shape and a generally linear injection needle that can provide a non-linear injection needle with a retractable structure to completely extract the liquid medicine, so that medical personnel have better operation convenience and avoid liquid medicine residue The medicine tank.

The liquid medicine tank of the present invention includes a tank body, a groove, a positioning plate, an opening and a bottom plate. The tank body is a hollow container, and the groove is recessed adjacent to the upper end of the side wall of the tank body On the top plate of the tank, the positioning plate is defined by the upper end of the side wall of the tank body separated by the groove. The opening is opened in the groove, and its height is lower than the top plate of the tank body. It can be formed by a soft plug Closed, the bottom plate is erected above the bottom of the peripheral wall of the tank body to form a high medicine containing space in the tank body. The bottom plate is inclined downwards from the outside to the inside, which can divert and collect the liquid medicine in the medicine containing space. Below the opening.

The effect of the present invention can provide a safety injection needle with a revolving structure extending into a non-linear shape. When the safety injection needle pierces the soft plug of the opening and penetrates into the medicine containing space in the tank, the positioning plate can make the safe injection The needle is suspended and positioned, and the liquid is guided through the bottom plate to collect the liquid under the opening, which can be used for the safety injection needle to completely extract the liquid in the medicine containing space to avoid the residual liquid from the liquid and the operation. Has better convenience.
