背景技术Background Art
富血小板凝胶在治疗糖尿病足尤其是难治性糖尿病足病具有非常良好的效果。而在富血小板凝胶的制造过程的灌胶步骤为：富血小板血浆与凝血酶激活剂按10:1的比例同时注射于创面，静置30-60秒后形成的凝胶即为富血小板凝胶。伤口用泡沫敷料覆盖、包扎，3-5天后观察伤口可见明显肉芽组织爬行。该步骤既对富血小板血浆与凝血酶激活剂比例有严格要求又强调同时注射于创面，操作者通常将装有富血小板血浆和凝血酶激活剂的两个注射器用三通管连接，然后同时推动两个注射器将富血小板血浆和凝血酶激活剂注射至创面，然而这样难以保证两者的比例，且两个注射器不在同一方向，单人操作难度大。Platelet-rich gel has a very good effect in treating diabetic foot, especially refractory diabetic foot disease. The gel-filling step in the manufacturing process of platelet-rich gel is: platelet-rich plasma and thrombin activator are injected into the wound at a ratio of 10:1 at the same time, and the gel formed after standing for 30-60 seconds is platelet-rich gel. The wound is covered and bandaged with a foam dressing, and after 3-5 days, obvious granulation tissue crawling can be seen in the wound. This step has strict requirements on the ratio of platelet-rich plasma to thrombin activator and emphasizes simultaneous injection into the wound. The operator usually connects two syringes containing platelet-rich plasma and thrombin activator with a three-way pipe, and then pushes the two syringes at the same time to inject platelet-rich plasma and thrombin activator into the wound. However, it is difficult to ensure the ratio of the two, and the two syringes are not in the same direction, which makes it difficult for one person to operate.

It has very good effects in treating diabetic foot, especially refractory diabetic foot disease.
富血小板凝胶的制作流程包括：(1)采血：抽取患者自体适量静脉血；(2)离心：采血管置于离心机以一定的转速离心，离心后静置5分钟；(3)制备富血小板血浆(PRP)：观察刻度，底层的为红细胞，上层的为贫血小板血浆(PPP)，中间呈白色雾状的即为血小板，按需抽取上层的贫血小板血浆，剩余的液体即为富血小板血浆，抽取富血小板血浆备用；(4)制备凝血酶激活剂：用10％的葡萄糖酸钙或者氯化钙溶解凝血酶冻干粉，充分摇匀，制成500U/ml的凝血酶激活剂；(5)灌胶：富血小板血浆与凝血酶激活剂按10:1的比例同时注射于创面，静置30-60秒后形成的凝胶即为富血小板凝胶。伤口用泡沫敷料覆盖、包扎，3-5天后观察伤口可见明显肉芽组织爬行。The production process of platelet-rich gel includes: (1) blood collection: draw an appropriate amount of venous blood from the patient; (2) centrifugation: place the blood collection tube in a centrifuge and centrifuge at a certain speed, and let it stand for 5 minutes after centrifugation; (3) prepare platelet-rich plasma (PRP): observe the scale, the bottom layer is red blood cells, the upper layer is platelet-poor plasma (PPP), and the white mist in the middle is platelets. The platelet-poor plasma in the upper layer is extracted as needed, and the remaining liquid is platelet-rich plasma. The platelet-rich plasma is extracted for later use; (4) prepare thrombin activator: dissolve thrombin freeze-dried powder with 10% calcium gluconate or calcium chloride, shake it thoroughly, and prepare 500U/ml thrombin activator; (5) gel filling: platelet-rich plasma and thrombin activator are injected into the wound at the same time in a ratio of 10:1. The gel formed after standing for 30-60 seconds is platelet-rich gel. The wound was covered and bandaged with foam dressing, and obvious granulation tissue crawling was observed in the wound after 3-5 days.
而在富血小板凝胶的制造过程的灌胶步骤为：富血小板血浆与凝血酶激活剂按10:1的比例同时注射于创面，静置30-60秒后形成的凝胶即为富血小板凝胶。伤口用泡沫敷料覆盖、包扎，3-5天后观察伤口可见明显肉芽组织爬行。该步骤既对富血小板血浆与凝血酶激活剂比例有严格要求又强调同时注射于创面，操作者通常将装有富血小板血浆和凝血酶激活剂的两个注射器用三通管连接，然后同时推动两个注射器将富血小板血浆和凝血酶激活剂注射至创面，然而这样难以保证两者的比例，且两个注射器不在同一方向，单人操作难度大。The gel-filling step in the manufacturing process of platelet-rich gel is: platelet-rich plasma and thrombin activator are injected into the wound surface at a ratio of 10:1 at the same time, and the gel formed after standing for 30-60 seconds is the platelet-rich gel. The wound is covered and bandaged with a foam dressing, and after 3-5 days, the wound can be observed to have obvious granulation tissue crawling. This step has strict requirements on the ratio of platelet-rich plasma to thrombin activator and emphasizes simultaneous injection into the wound surface. The operator usually connects two syringes containing platelet-rich plasma and thrombin activator with a three-way pipe, and then pushes the two syringes at the same time to inject platelet-rich plasma and thrombin activator into the wound surface. However, it is difficult to ensure the ratio of the two, and the two syringes are not in the same direction, which makes it difficult for one person to operate.
因此，参照图1至图2，本实用新型提供了一种双管注射器，并作出如下实施例：Therefore, referring to Figures 1 to 2, the utility model provides a double-barreled syringe, and makes the following embodiments:
在一些实施例中，一种双管注射器，包括并排设置的粗针管100和细针管200，所述粗针管100和细针管200下端均设有出药嘴110，所述粗针管100和细针管200内部套设有与其配套的活塞杆120，所述活塞杆120外端设有按压块121，两个所述按压块121可拆设置有总压块300；Y型管400包括相互连通的两个分支进液管道和一个分支出液管道，两个分支进液管道分别与两个出药嘴110连接，所述分支出液管道连接有针嘴500。In some embodiments, a double-tube syringe includes a thick needle tube 100 and a thin needle tube 200 arranged side by side, and the lower ends of the thick needle tube 100 and the thin needle tube 200 are each provided with a medicine outlet nozzle 110, and the thick needle tube 100 and the thin needle tube 200 are internally sleeved with a piston rod 120 matching therewith, and the outer end of the piston rod 120 is provided with a pressing block 121, and the two pressing blocks 121 are detachably provided with a total pressing block 300; the Y-shaped tube 400 includes two branch liquid inlet pipes and one branch liquid outlet pipe that are interconnected, and the two branch liquid inlet pipes are respectively connected to the two medicine outlet nozzles 110, and the branch liquid outlet pipe is connected to a needle nozzle 500.
做血小板凝胶时根据创面大小确定所需富血小板血浆的剂量，再根据所需富血小板血浆剂量选择20:2ml、10:1ml、5:0.5ml等不同规格的双管注射器，不同规格的双管注射器中的粗针管100和细针管200容量比都是10:1，其中粗针管100用来抽吸富血小板凝胶，细针管200用来抽吸凝血酶激活剂，灌胶时用Y型管400连接粗针管100和细针管200，同时推动粗针管100和细针管200的活塞。这样既可以保证富血小板血浆和凝血酶激活剂的比例，又可以使得两种液体充分混合注射到创面。When making platelet gel, the required platelet-rich plasma dosage is determined according to the size of the wound, and then double-tube syringes of different specifications such as 20:2ml, 10:1ml, and 5:0.5ml are selected according to the required platelet-rich plasma dosage. The volume ratio of the thick needle tube 100 and the thin needle tube 200 in the double-tube syringes of different specifications is 10:1, wherein the thick needle tube 100 is used to draw platelet-rich gel, and the thin needle tube 200 is used to draw thrombin activator. When filling the gel, the thick needle tube 100 and the thin needle tube 200 are connected with a Y-shaped tube 400, and the pistons of the thick needle tube 100 and the thin needle tube 200 are pushed at the same time. In this way, the ratio of platelet-rich plasma and thrombin activator can be ensured, and the two liquids can be fully mixed and injected into the wound.
在抽取液体时，总压块300从按压块121拆装，分别拉动活塞杆120进行抽取液体，在注射时，总压块300安装于按压块121上，方便按相同比例注射，操作更为方便。也可以同时将两个出药嘴110与两种不同的液体连通，拉动总压块300，同时按比例抽取不同液体，操作更加灵活。可以单人完成注射操作。When extracting liquid, the total pressure block 300 is disassembled from the pressing block 121, and the piston rod 120 is pulled to extract liquid. When injecting, the total pressure block 300 is installed on the pressing block 121, which is convenient for injection in the same proportion and more convenient to operate. The two medicine outlets 110 can also be connected to two different liquids at the same time, and the total pressure block 300 is pulled to extract different liquids in proportion at the same time, which is more flexible to operate. The injection operation can be completed by one person.
进一步改进，所述总压块300包括卡接块310和设于卡接部顶部的按压板320，所述卡接块310的底部设有两个卡接槽311，所述按压块121分别卡接于所述卡接槽311。卡接结构简单，操作容易。As a further improvement, the total pressure block 300 includes a clamping block 310 and a pressing plate 320 disposed at the top of the clamping portion, and the bottom of the clamping block 310 is provided with two clamping grooves 311, and the pressing blocks 121 are respectively clamped in the clamping grooves 311. The clamping structure is simple and easy to operate.
进一步改进，所述卡接块310的侧边设有与所述卡接槽311连通的插入通槽312。卡接更为牢固。在其他一些实施例中，也可不设置插入通槽312，直接从下往上卡接，这种卡接方式，卡接力度较大，可能会使得活塞杆120相对粗针管100活动，影响液体存储。设置插入通槽312，则可以将按压块121从插入通槽312滑入卡接，卡接力度较小，不容易使得活塞杆120相对粗针管100活动，更符合实际使用情况。As a further improvement, the side of the clamping block 310 is provided with an insertion slot 312 connected to the clamping slot 311. The clamping is more secure. In some other embodiments, the insertion slot 312 may not be provided, and the clamping is directly from bottom to top. This clamping method has a large clamping force, which may cause the piston rod 120 to move relative to the thick needle tube 100, affecting liquid storage. If the insertion slot 312 is provided, the pressing block 121 can be slid into the insertion slot 312 for clamping. The clamping force is small, and it is not easy for the piston rod 120 to move relative to the thick needle tube 100, which is more in line with actual usage.
进一步改进，所述分支出液管道的直径大于所述分支进液管道。便于液体混合。As a further improvement, the diameter of the branch liquid outlet pipe is larger than that of the branch liquid inlet pipe, so as to facilitate liquid mixing.
进一步改进，所述粗针管100和细针管200的横截面积比为10:1。面积比为10:1，则推动相同的长度，注入的液体量比也为10:1，因此可以同时推动按压块121，即可控制注射比例。一般常用的注射剂为20:2ml、10:1ml、5:0.5ml。As a further improvement, the cross-sectional area ratio of the thick needle tube 100 and the thin needle tube 200 is 10:1. When the area ratio is 10:1, the ratio of the amount of liquid injected is also 10:1 when the same length is pushed, so the pressing block 121 can be pushed at the same time to control the injection ratio. Commonly used injections are 20:2ml, 10:1ml, and 5:0.5ml.
进一步改进，所述分支进液管道与出药嘴110可拆连接，常用的方式为插接，或者螺纹连接。As a further improvement, the branch liquid inlet pipe is detachably connected to the medicine outlet nozzle 110, and a common method is plug-in connection or threaded connection.
进一步改进，所述粗针管100和细针管200均设有刻度。便于观测抽取量。As a further improvement, both the thick needle tube 100 and the thin needle tube 200 are provided with scales to facilitate observation of the extraction amount.
进一步改进，所述Y型管400为软质管件。操作更加方便。As a further improvement, the Y-shaped tube 400 is a soft tube, which makes the operation more convenient.
进一步改进，所述粗针管100和细针管200为透明构件。便于观测抽取量。As a further improvement, the thick needle tube 100 and the thin needle tube 200 are transparent components, so as to facilitate observation of the extraction amount.
进一步改进，所述粗针管100和细针管200可以由连接件卡接并排固定。使得粗针管100和细针管200也可单独注射使用。具体地，卡接件设置有两个安装槽，所述粗针管100和细针管200分别卡接于所述安装槽内。As a further improvement, the thick needle tube 100 and the thin needle tube 200 can be fixed side by side by a connector, so that the thick needle tube 100 and the thin needle tube 200 can also be used for injection separately. Specifically, the connector is provided with two mounting grooves, and the thick needle tube 100 and the thin needle tube 200 are respectively mounted in the mounting grooves.
以上对本实用新型的较佳实施方式进行了具体说明，但本发明创造并不限于实施例，熟悉本领域的技术人员在不违背本实用新型精神的前提下还可作出种种的等同变型或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。The preferred implementation modes of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
