输液是疾病治疗的一种常用治疗方式。目前，主要是依靠药液的重力，通过调节输液管上的流量调节器来调节输液的速度，流量调节器打开的越大，输液速度就会越快，反之，输液速度就会越慢。由于是依靠重力输液，通常需要输液架或专人提着输液袋才能正常输液。Infusion is a common treatment modality for disease treatment. At present, the speed of infusion is regulated by adjusting the flow regulator on the infusion tube mainly relying on the gravity of the liquid medicine. The larger the flow regulator is opened, the faster the infusion speed will be, otherwise, the slower the infusion speed will be. Due to relying on gravity infusion, it usually requires an infusion stand or a special person to carry the infusion bag to perform normal infusion.
但是，对于目前抢救烧伤，大出血的病人时，需要大剂量的输液。依靠重力输液，其流速都无法满足抢救的需要，目前，医院大剂量输液，都是采用人工挤压输液袋的办法来提高液体的流速。其缺点是需要专人来手动打气加压，其输液速度不稳定，影响抢救效果。But, when rescuing burn at present, the patient of massive hemorrhage, needs the transfusion of large dose.

具体实施方式Detailed ways
下面结合附图和具体实施例对本实用新型进行详细说明。The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
如图1所述，在一个实施例中，一种输液加压器，包括控制器110、输气管120与用于收容输液袋20的加压袋130。控制器110包括微处理器111、气室112、充气装置113、排气装置114与气压传感器115。此外，控制器110还包括为处理器、充气装置113、排气装置114与气压传感器115进行供电的电源116。充气装置113与排气装置114分别连通至气室112。通常，充气装置113为充气泵，排气装置114为电磁阀或吸气泵。气压传感器115的传感元件伸入气室112内，加压袋130具有气囊132，气囊132通过输气管120与气室112相连通，微处理器111分别电连接充气装置113、排气装置114与气压传感器115，微处理器111获取用户设置的预设压力，控制充气装置113向气室112充气，气压传感器115检测气室112的气压并将检测的气压信号传输至微处理器111，当气室112的气压达到预设压力时，微处理器111控制充气装置113停止充气，当气室112的气压大于预设压力时，微处理器111控制排气装置114对气室112放气。As shown in FIG. 1 , in one embodiment, an infusion pressurizer includes a controller 110 , an air delivery tube 120 and a pressurized bag 130 for accommodating an infusion bag 20 . The controller 110 includes a microprocessor 111 , an air chamber 112 , an inflation device 113 , an exhaust device 114 and an air pressure sensor 115 . In addition, the controller 110 also includes a power supply 116 for powering the processor, the inflation device 113 , the exhaust device 114 and the air pressure sensor 115 . The inflator 113 and the exhaust device 114 communicate with the air chamber 112 respectively. Usually, the inflation device 113 is an air pump, and the exhaust device 114 is a solenoid valve or an air suction pump. The sensing element of the air pressure sensor 115 stretches into the air chamber 112, the pressurized bag 130 has an air bag 132, the air bag 132 communicates with the air chamber 112 through the air pipe 120, and the microprocessor 111 is electrically connected to the inflation device 113 and the exhaust device 114 respectively. With the air pressure sensor 115, the microprocessor 111 obtains the preset pressure set by the user, controls the inflator 113 to inflate the air chamber 112, the air pressure sensor 115 detects the air pressure of the air chamber 112 and transmits the detected air pressure signal to the microprocessor 111, when When the air pressure of the air chamber 112 reaches the preset pressure, the microprocessor 111 controls the inflation device 113 to stop inflating, and when the air pressure of the air chamber 112 is greater than the preset pressure, the microprocessor 111 controls the exhaust device 114 to deflate the air chamber 112.
上述输液加压器，微处理器111控制充气装置113对加压袋130的气囊132进行充气，加压袋130充气膨胀后挤压收容于加压袋130内部的输液袋20，从而加快输液袋20对人体40的输液流量，同时，气压传感器115实时检测气室112的气压，当气室112的气压达到预设压力时，微处理器111控制充气装置113停止充气，当气室112的气压大于预设压力时，微处理器111控制排气装置114对气室112放气，从而保持气囊132内气压的稳定，保证了输液流量的稳定。In the above-mentioned infusion pressurizer, the microprocessor 111 controls the inflator 113 to inflate the air bag 132 of the pressurized bag 130. After the pressurized bag 130 is inflated and inflated, it squeezes the infusion bag 20 contained in the pressurized bag 130, thereby speeding up the pressure of the infusion bag. 20 to the infusion flow rate of the human body 40. At the same time, the air pressure sensor 115 detects the air pressure of the air chamber 112 in real time. When the air pressure of the air chamber 112 reaches the preset pressure, the microprocessor 111 controls the inflator 113 to stop inflating. When the pressure is greater than the preset pressure, the microprocessor 111 controls the exhaust device 114 to deflate the air chamber 112, thereby maintaining the stability of the air pressure in the air bag 132 and ensuring the stability of the infusion flow.
在野外没有输液支架的情况下，本实用新型也可正常输液。可将该实用新型放置于担架上或固定在患者四肢上，再配上可自动排气的精密过滤输液器就可实施输液，由于输液是靠加压袋130挤压输液袋20，所以无需专人拿着输液袋20靠重力输液，大大减轻了医务人员的工作强度。Under the situation that there is no infusion stand in the field, the utility model can also be infused normally. The utility model can be placed on a stretcher or fixed on the patient's limbs, and the infusion can be implemented by adding a precision filter infusion set that can automatically exhaust. Since the infusion is squeezed by the pressurized bag 130, the infusion bag 20 is not required. Hold the infusion bag 20 and infuse by gravity, which greatly reduces the work intensity of the medical personnel.
在本实施例中，加压袋130还具有第一内膜、第二内膜、外膜与用于收容输液袋20的收容腔，第一内膜与第二内膜相对设置形成收容腔，第一内膜、第二内膜与外膜形成气囊132。加压袋130包围于输液袋20的外围，使输液袋20受压较均匀。In this embodiment, the pressurized bag 130 also has a first inner membrane, a second inner membrane, an outer membrane and a storage chamber for accommodating the infusion bag 20, the first inner membrane and the second inner membrane are oppositely arranged to form a storage chamber, The first intima, the second intima and the adventitia form a balloon 132 . The pressurized bag 130 surrounds the periphery of the infusion bag 20 so that the infusion bag 20 is compressed more evenly.
在本实施例中，输液加压器还包括橡胶球囊，橡胶球囊连通至气囊132、输气管120或气室112。在野外输液时，可能会遇上没电的情况。本实用新型提供了手动方式仍然可以正常输液。In this embodiment, the infusion pressurizer further includes a rubber balloon, which is connected to the air bag 132 , the air tube 120 or the air chamber 112 . During infusion in the field, there may be no electricity. The utility model provides that the manual mode can still infuse normally.
在本实施例中，输液加压器还包括热力贴，热力贴贴设于输液袋20上。在野外某些特殊的环境下，比如高热或高寒的情况下输液，我们需要对输液袋内的液体进行降温或加温。使用电源116来给输液袋加温或降温显然是不现实的。本实用新型采用化学或物理的办法实现这一要求。In this embodiment, the infusion pressurizer further includes a thermal patch, and the thermal patch is attached to the infusion bag 20 . In some special environments in the field, such as infusion in high fever or high cold, we need to cool down or warm up the liquid in the infusion bag. It is obviously unrealistic to use the power supply 116 to heat or cool down the infusion bag. The utility model realizes this requirement by means of chemistry or physics.
要求加温时，我们采用化学的方法在输液袋20两面贴上热力贴，撕去保护纸后即可给输液袋20加热。When heating is required, we use a chemical method to paste thermal stickers on both sides of the infusion bag 20, and the infusion bag 20 can be heated after the protective paper is torn off.
降温我们采用物理的办法，将输液袋放置于清洁的冷水或冰块中，以降低输液袋内药液的温度。这种化学或物理升降温的办法好处是，不需要耗费宝贵的电能，且操作简单易行，成本较低。由于是对输液袋外部常规的加温或降温，所以避免了外部环境对输液袋内部药液的污染，特别适合野外输液。输液完毕，微处理器111将控制排气装置排气，直到加压袋130内气压降为零为止。To cool down, we use physical methods to place the infusion bag in clean cold water or ice to reduce the temperature of the medicinal solution in the infusion bag. The advantage of this method of chemical or physical heating and cooling is that it does not need to consume precious electric energy, and the operation is simple and easy, and the cost is low. Due to the routine heating or cooling of the outside of the infusion bag, it avoids the external environment from polluting the medicinal liquid inside the infusion bag, and is especially suitable for field infusion. After the infusion is completed, the microprocessor 111 will control the exhaust device to exhaust the air until the air pressure in the pressurized bag 130 drops to zero.
本发明的电源116分动力电源和系统电源两部分。The power supply 116 of the present invention is divided into two parts, a power supply and a system power supply.
动力电源采用大容量，高效率的可充电电池，如锂电池，它是提供给气泵自动加压的动力源，可更换。动力电池充满电后，在1000毫升/小时的速度下，可连续输500毫升容量的输液袋40袋以上。The power source adopts a high-capacity, high-efficiency rechargeable battery, such as a lithium battery, which is a power source for the automatic pressurization of the air pump and can be replaced. After the power battery is fully charged, it can continuously infuse more than 40 infusion bags with a capacity of 500 ml at a speed of 1000 ml/hour.
系统电源同样采用大容量，高效率的可充电电池，如锂电池，它是控制及保持数据的能量源。电量不足时，可用外部电源适配器给予充电。仅供显示用时，充满电后可连续工作50小时以上。本产品在使用的过程中还具有待机，液路异常，气路异常，动力电池欠压，动力电池耗尽，系统电池欠压，系统电池耗尽等提示功能，以确保输液的安全。The system power also uses a large capacity, high efficiency rechargeable battery, such as a lithium battery, which is the energy source for controlling and maintaining data. When the power is insufficient, an external power adapter can be used to charge it. When it is only for display, it can work continuously for more than 50 hours after being fully charged. During the use of this product, there are also prompt functions such as standby, abnormal liquid circuit, abnormal gas circuit, power battery undervoltage, power battery exhaustion, system battery undervoltage, system battery exhaustion, etc., to ensure the safety of infusion.
以上所述实施例仅表达了本实用新型的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。因此，本实用新型专利的保护范围应以所附权利要求为准。The above-mentioned embodiments only express several implementations of the utility model, and the description thereof is relatively specific and detailed, but it should not be construed as limiting the patent scope of the utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
