西林瓶配药装置及配药方法Vial dispensing device and dispensing method

技术领域technical field

本发明涉及医疗器械技术领域，特别是涉及一种西林瓶配药装置及配药方法。The invention relates to the technical field of medical devices, in particular to a vial dispensing device and a dispensing method.

背景技术Background technique

配药是静脉输液的一项常规工作，通常具有标准的操作流程，通常是借助注射器将不同的药剂混合在一起。由于医药产业的标准化，现如今仍然有大量的药剂是采用西林瓶装载的，因此，配药作业也有很多是在西林瓶中进行的。The dispensing of medicines is a routine job of intravenous infusion, usually with standard operating procedures, usually mixing different medicines together with the help of syringes. Due to the standardization of the pharmaceutical industry, a large number of medicines are still loaded in vials, so many dispensing operations are carried out in vials.

然而，西林瓶往往较小而且密封性很好，特别是对于容量在10ml以下的西林瓶，注射器注入或者抽吸瓶内药剂时都会引起瓶内气压剧烈的变化，使得药剂注入或吸出不顺畅，还容易残留或者泄漏，尤其是在对橡胶瓶盖多次穿刺之后。有些药剂对于正常人是有健康损害的，这种常规的西林瓶配药过程会影响医护人员自身的健康。However, vials are often small and well-sealed, especially for vials with a volume below 10ml. When injecting or aspirating the drug in the bottle, the air pressure in the bottle will change drastically, making the injection or suction of the drug difficult. It is also prone to residue or leakage, especially after multiple punctures of the rubber cap. Some medicaments are harmful to normal people's health, and this routine dispensing process of vials can affect the health of medical staff.

专利号为CN202210768084，名称为“一种侧导管型全封闭式安全配药装置”的发明专利，以及专利号为CN201981035166，名称为“一种配药用注射器针头”的实用新型专利等，都提供了能够平衡配药的西林瓶内外气压的装置和方案。然而，上述方案都是将两根管道集中到一根针管中，采用套管的方式实现药剂注射和气压平衡，这种方案看起来间接方便，但生产这种装置则极为困难，要想在较细的针管中开辟多条通路，并且通路还可能是弯曲的，目前可能只有采用3D打印的生产工艺，很显然，采用这种工艺生产配药装置，实在大材小用，效率也低，成本很高。再者，现有技术中的配药装置排气针和药剂针都是相对固定的，要么只能将西林瓶正放取药，要么只能倒放取药，不能灵活自由调节，操作适应性不佳，还是存在一定程度的不便，需要有进一步的改进。The patent number is CN202210768084, the invention patent named "a side catheter type fully enclosed safety dispensing device", and the utility model patent named CN201981035166, named "a syringe needle for dispensing", etc., all provide The device and scheme capable of balancing the internal and external air pressures of the vials for dispensing medicines. However, the above-mentioned solutions all concentrate two pipelines into one needle tube, and use a sleeve to realize drug injection and air pressure balance. This solution seems to be indirect and convenient, but it is extremely difficult to produce this device. Multiple channels are opened in the thin needle tube, and the channels may be curved. At present, only the production process of 3D printing may be used. Obviously, using this process to produce dispensing devices is really overkill, low efficiency, and high cost. Furthermore, the exhaust needle and the drug needle of the dispensing device in the prior art are relatively fixed, and either the vial can only be placed upright to take the medicine, or it can only be put upside down to take the medicine, which cannot be adjusted flexibly and freely, and the operation adaptability is not good. Good, there is still a certain degree of inconvenience, and further improvement is needed.

下面以具体地实施例对本发明的技术方案以及该技术方案如何解决上述的技术问题进行详细说明。The technical solution of the present invention and how the technical solution solves the above-mentioned technical problems will be described in detail below with specific embodiments.

本申请第一个方面的实施例提供了一种西林瓶配药装置，如图1和图2所示，包括第一穿刺针100、连接软管300、气瓶400、注射器(图中未示意)和至少一根第二穿刺针200。The embodiment of the first aspect of the present application provides a vial dispensing device, as shown in Figure 1 and Figure 2, including afirst puncture needle 100, a connectinghose 300, agas cylinder 400, and a syringe (not shown in the figure) and at least onesecond puncture needle 200.

其中，第一穿刺针100的针管为弯折针管，第一穿刺针100的针管的弯折处设置有按压块110。第二穿刺针200通过连接软管300与气瓶400连接，注射器可卡接在第二穿刺针200的连接部上。Wherein, the needle tube of thefirst puncture needle 100 is a bent needle tube, and the bending part of the needle tube of thefirst puncture needle 100 is provided with apressing block 110 . Thesecond puncture needle 200 is connected to thegas bottle 400 through the connectinghose 300 , and the syringe can be clamped on the connection part of thesecond puncture needle 200 .

本申请的实施例中，注射器可直接选用现有技术中的成熟商品，也可生产与第二穿刺针200一体化连接的，或者固定连接的一次性注射器。当注射器选用普通注射器时，注射器可密封套设到第二穿刺针200上。第一穿刺针100、连接软管300以及气瓶400的作用是向封闭的、容积很小的西林瓶10补充空间，补充气压，当西林瓶10中的液体被抽出，西林瓶10中气压下降时，气瓶400中的气体可快速进入到西林瓶10中使得瓶中气压恢复。而当西林瓶10中被注入药剂，瓶中气压变大时，多余的气体会进入气瓶400中，同样可以使得西林瓶10中的气压不会大幅度上升，降低药剂注入的难度。第二穿刺针200及注射器的作用是向西林瓶10中注入或者抽吸药剂。In the embodiment of the present application, the syringe can be directly selected from a mature commodity in the prior art, or a disposable syringe integrally connected with thesecond puncture needle 200 or fixedly connected can also be produced. When the syringe is a common syringe, the syringe can be sleeved on thesecond puncture needle 200 in a sealed manner. The functions of thefirst puncture needle 100, the connectinghose 300 and thegas cylinder 400 are to supplement space and air pressure to theclosed vial 10 with very little volume. When the liquid in thevial 10 is drawn out, the air pressure in thevial 10 drops At this time, the gas in thegas cylinder 400 can quickly enter thevial 10 so that the air pressure in the bottle is restored. And when medicament is injected in thevial 10, when the air pressure in the bottle becomes larger, excess gas will enter in thegas cylinder 400, which can also make the air pressure in thevial 10 not rise significantly, reducing the difficulty of medicament injection. The function of thesecond puncture needle 200 and the syringe is to inject or draw medicine into thevial 10 .

由于第一穿刺针100与连接软管300连接，将第一穿刺针100设置成弯折状态，方便在狭窄的西林瓶10瓶盖410上留下第二穿刺针200的操作空间，设置按压块110则方便对第一穿刺针100进行穿刺作业。按压块110的顶部可以设置成跟手指表面形状类似凹坑，以使得操作更舒适。Since thefirst puncture needle 100 is connected with the connectinghose 300, thefirst puncture needle 100 is set in a bent state, which is convenient to leave an operating space for thesecond puncture needle 200 on thebottle cap 410 of thenarrow vial 10, and a pressing block is provided. 110 facilitates the puncturing operation of thefirst puncture needle 100 . The top of thepressing block 110 can be configured as a pit similar to the surface of a finger, so as to make the operation more comfortable.

S20：将第二穿刺针与带有第二药剂的注射器组装后，刺入西林瓶内。S20: After assembling the second puncture needle and the syringe with the second medicament, puncture it into the vial.

S30：调整第一穿刺针和第二穿刺针在西林瓶中的位置，将第二药剂注入西林瓶内，混药后，通过注射器吸取西林瓶内的药剂，拔出第一穿刺针和第二穿刺针。S30: Adjust the positions of the first puncture needle and the second puncture needle in the vial, inject the second medicament into the vial, after mixing the medicines, draw the medicament in the vial through the syringe, and pull out the first puncture needle and the second puncture needle. puncture needle.

操作人员做好清洁消毒作业后，拿起第一穿刺针100，将针头对准待配药的西林瓶10，按住按压块110，将第一穿刺针100刺入到西林瓶10内，实现西林瓶10与气瓶400的连通。在需要将西林瓶10倒置以便于更彻底地吸取其中的第一药剂时，此时第一药剂一般是液体药剂，第一穿刺针100应该深入西林瓶10，由于西林瓶10与气瓶400的气压相同，第一药剂不会从第一穿刺针100进入到气瓶400内。After cleaning and disinfecting, the operator picks up thefirst puncture needle 100, aligns the needle with thevial 10 to be dispensed, presses thepressing block 110, and inserts thefirst puncture needle 100 into thevial 10 to realize The communication between thebottle 10 and thegas cylinder 400. When thevial 10 needs to be turned upside down so as to absorb the first medicament therein more thoroughly, the first medicament is generally a liquid medicament at this time, and thefirst puncture needle 100 should go deep into thevial 10, because thevial 10 and thegas cylinder 400 With the same air pressure, the first medicament will not enter thegas cylinder 400 from thefirst puncture needle 100 .

刺入第一穿刺针100后，可以接着刺入第二穿刺针200，如果是需要吸取西林瓶10中的第一药剂，需要将第二穿刺针200深入到液面以下，而如果是倒置西林瓶10，则第二穿刺针200只需刺入到西林瓶10内即可。在西林瓶10倒置的情况下，第一穿刺针100的针尖可以更靠近西林瓶10的瓶底，而第二穿刺针200的针尖可以更靠近西林瓶10的瓶口。After thefirst puncture needle 100 is pierced, thesecond puncture needle 200 can then be pierced. If the first medicament in thevial 10 needs to be sucked, thesecond puncture needle 200 needs to be penetrated below the liquid level, and if the penetrating needle is invertedbottle 10, then thesecond puncture needle 200 only needs to pierce in thevial 10 and get final product. When thevial 10 is upside down, the needle point of thefirst puncture needle 100 can be closer to the bottom of thevial 10 , and the needle point of thesecond puncture needle 200 can be closer to the mouth of thevial 10 .

如果需要向西林瓶10内注入第二药剂，当西林瓶10内原本的第一药剂是液体药剂，第一穿刺针100和第二穿刺针200的针尖都可以靠近西林瓶10的瓶口。本申请的第一穿刺针100和第二穿刺针200并非固定在同一个连接零件上，因此可以随时灵活调整。当西林瓶10内原本的第一药剂是粉剂，则可在西林瓶10正放的情况下，使得第二穿刺针200的针尖更靠近西林瓶10的瓶底，第一穿刺针100的针尖更靠近西林瓶10的瓶口，避免粉剂虽气流进入到第一穿刺针100内，并进入到气瓶400内，也避免造成第一药剂的流失同时堵塞第一穿刺针100、连接软管300，或污染气瓶400。If the second medicament needs to be injected into thevial 10 , when the original first medicament in thevial 10 is a liquid medicament, the needle points of thefirst puncture needle 100 and thesecond puncture needle 200 can be close to the mouth of thevial 10 . Thefirst puncture needle 100 and thesecond puncture needle 200 of the present application are not fixed on the same connecting part, so they can be flexibly adjusted at any time. When the original first medicament in thevial 10 is powder, then the needle point of thesecond puncture needle 200 can be closer to the bottom of thevial 10 when thevial 10 is placed upright, and the needle point of thefirst puncture needle 100 can be closer to the bottom of thevial 10. Close to the bottle mouth of thevial 10, prevent the powder from entering thefirst puncture needle 100 and thegas cylinder 400 through the air flow, and avoid the loss of the first medicament and block thefirst puncture needle 100 and the connectinghose 300 at the same time. Or pollutecylinders 400.
