说明书附图中的附图标记包括：控制器1、支撑架2、截止阀3、医用导气管4、引流管5、负压吸取器6、出水清洗管7、流量控制阀8、水泵9、水管10、肠胃清洗液箱11、电磁加热器12、洗胃管13、挡片14、压力传感器15、摄像头16、透水孔131。The reference signs in the drawings of the description include: controller 1, support frame 2, stop valve 3, medical airway tube 4, drainage tube 5, negative pressure suction device 6, outlet water cleaning tube 7, flow control valve 8, water pump 9, Water pipe 10, gastrointestinal cleaning liquid tank 11, electromagnetic heater 12, gastric lavage tube 13, baffle 14, pressure sensor 15, camera 16, water permeable hole 131.
实施例基本如图1所示：一种内科用肠胃清洗装置，包括支撑架2、控制器1、肠胃清洗液箱11，控制器1与肠胃清洗液箱11均固定安装在支撑架2上，肠胃清洗液箱11底部设置有电磁加热器12。支撑架2上还设有水泵9，水泵9的入口与肠胃清洗液箱11通过水管10连通。支撑架2上还固定安装有负压吸取器6，负压吸取器6上设有引流管5。水泵9的出口处设有出水清洗管7，出水清洗管7与引流管5均连接有洗胃管13。如图1所示，洗胃管13的中部固定设有一挡片14，挡片14与洗胃管13的右侧形成一个封闭的腔体，出水清洗管7的端头与挡片14固定连接并与腔体相连通，引流管5的端头穿过挡片14和腔体、并同时延伸至洗胃管13的右端。洗胃管13的右侧壁上还设有透水孔131，透水孔131分别与腔体和洗胃管13的外部相通，即清洗液通过透水孔131进入到患者的胃中。洗胃管13的右端还设有摄像头16，摄像头16、负压吸取器6和水泵9分别与控制器1电连接。The embodiment is basically shown in Figure 1: an internal medicine gastrointestinal cleansing device, including a support frame 2, a controller 1, and a gastrointestinal cleansing liquid tank 11, the controller 1 and the gastrointestinal cleansing liquid tank 11 are fixedly installed on the support frame 2, An electromagnetic heater 12 is arranged at the bottom of the stomach cleaning solution tank 11 . The support frame 2 is also provided with a water pump 9 , and the inlet of the water pump 9 communicates with the stomach cleaning solution tank 11 through a water pipe 10 . A negative pressure absorber 6 is also fixedly installed on the support frame 2 , and a drainage tube 5 is arranged on the negative pressure absorber 6 . The outlet of the water pump 9 is provided with a water outlet cleaning pipe 7, and both the water outlet cleaning pipe 7 and the drainage pipe 5 are connected with a gastric lavage tube 13. As shown in Figure 1, the middle part of the gastric lavage tube 13 is fixedly provided with a baffle 14, the baffle 14 forms a closed cavity with the right side of the gastric lavage tube 13, and the end of the outlet cleaning pipe 7 is fixedly connected with the baffle 14 And communicate with the cavity, the end of the drainage tube 5 passes through the baffle 14 and the cavity, and extends to the right end of the gastric lavage tube 13 at the same time. The right side wall of the gastric lavage tube 13 is also provided with a permeable hole 131, and the permeable hole 131 communicates with the cavity and the outside of the gastric lavage tube 13 respectively, that is, the cleaning solution enters the patient's stomach through the permeable hole 131. The right end of gastric lavage tube 13 is also provided with camera 16, and camera 16, negative pressure absorber 6 and water pump 9 are electrically connected with controller 1 respectively.
本实施例在实施时，将洗胃管13深入患者的胃中，利用摄像头16查看患者胃里的情况，找到清洗的位置。水泵9将肠胃清洗液箱11内的清洗液通过水管10抽出、并由出水清洗管7将清洗液输送至洗胃管13的腔体内，腔体内的清洗液再次通过透水孔131进入到患者的胃中。负压吸取器6则通过引流管5的端头不断的将患者胃中的清洗液和清除物吸走，以完成对患者的肠胃清洗。由于引流管5的端头穿过洗胃管13的腔体，而出水清洗管7是将清洗液输送至腔体内，因此，患者的胃中会一直不断的有清洗液存积，这样引流管5的端头就能一直浸入到患者胃中的清洗液中，并使引流管5不会吸走患者胃中的空气，进而维持了患者胃中的空气压力稳定。When this embodiment is implemented, the gastric lavage tube 13 is inserted deep into the patient's stomach, and the camera 16 is used to check the situation in the patient's stomach to find the cleaning position. The water pump 9 extracts the cleaning solution in the stomach cleaning solution tank 11 through the water pipe 10, and the cleaning solution is delivered to the cavity of the gastric lavage tube 13 by the outlet cleaning tube 7, and the cleaning solution in the cavity enters the patient's body through the permeable hole 131 again. in the stomach. The negative pressure aspirator 6 continuously sucks away the cleaning liquid and clearing matter in the patient's stomach through the end of the drainage tube 5, so as to complete the cleaning of the patient's intestines and stomach. Since the end of the drainage tube 5 passes through the cavity of the gastric lavage tube 13, and the water outlet cleaning tube 7 transports the cleaning solution to the cavity, the patient's stomach will always have the cleaning solution accumulated, so that the drainage tube 5 can be immersed in the cleaning solution in the patient's stomach all the time, and the drainage tube 5 will not suck the air in the patient's stomach, thereby maintaining the stability of the air pressure in the patient's stomach.
如图1所示，为了进一步防止患者的胃中形成负压，洗胃管13上还设有一根医用导气管4，医用导气管4上设有一个用于控制医用导气管4通断的截止阀3。医用导气管4的一端与洗胃管13的腔体连通、另一端与洗胃管13的外部连通。当引流管5抽取到的清洗液和清除物不足以满足负压吸取器6的吸取流量时，打开截止阀3使医用导气管4通气，通过医用导气管4就可以向患者的胃中快速的补充外界空气压力，促使患者的胃中不会形成负压。而不适用医用导气管4时，只需要关闭截止阀3使得医用导气管4处于不透气的断开状态即可。As shown in Figure 1, in order to further prevent negative pressure from forming in the patient's stomach, a medical airway tube 4 is also provided on the gastric lavage tube 13, and a cut-off for controlling the on-off of the medical airway tube 4 is provided on the medical airway tube 4. valve 3. One end of the medical airway tube 4 communicates with the cavity of the gastric lavage tube 13 , and the other end communicates with the outside of the gastric lavage tube 13 . When the cleaning liquid and clearings extracted by the drainage tube 5 are not enough to meet the suction flow rate of the negative pressure suction device 6, the shut-off valve 3 is opened to ventilate the medical airway tube 4, and the medical airway tube 4 can be quickly injected into the stomach of the patient. Supplement the external air pressure so that negative pressure does not form in the patient's stomach. When the medical airway tube 4 is not applicable, it is only necessary to close the stop valve 3 so that the medical airway tube 4 is in an airtight disconnected state.
如图1所示，洗胃管13的腔体内还设有压力传感器15，压力传感器15与控制器1电连接。压力传感器15用于检测腔体内的空气压力，因为腔体与患者的肠胃通过透水孔131相连通，因此压力传感器15也同时用于检测患者胃中的空气压力。当患者胃中空气压力或者腔体内的空气压力增大或者减小超出预先设定的安全范围值时，则压力传感器15向控制器1发出电信号，由控制器1分别控制水泵9或者是负压吸取器6的启停以维持患者胃中的空气压力处于稳定的状态。As shown in FIG. 1 , a pressure sensor 15 is also provided in the cavity of the gastric lavage tube 13 , and the pressure sensor 15 is electrically connected to the controller 1 . The pressure sensor 15 is used to detect the air pressure in the cavity, because the cavity communicates with the patient's intestines and stomach through the water-permeable hole 131, so the pressure sensor 15 is also used to detect the air pressure in the patient's stomach. When the air pressure in the patient's stomach or the air pressure in the cavity increases or decreases beyond the preset safe range value, the pressure sensor 15 sends an electrical signal to the controller 1, and the controller 1 controls the water pump 9 or negative The start and stop of the pressure aspirator 6 is in a stable state to maintain the air pressure in the patient's stomach.
本优化的实施例中，出水清洗管7上还设有流量控制阀8。当患者感觉到胃中的清洗液过多时，可在不停止负压吸取器6的同时，通过调节流量控制阀8以调节出水清洗管7的清洗液的输出，减少向患者胃中输入清洗液的流量，进而减轻患者的不适。In this optimized embodiment, a flow control valve 8 is also provided on the outlet water cleaning pipe 7 . When the patient feels that there is too much cleaning fluid in the stomach, the flow control valve 8 can be adjusted to adjust the output of the cleaning fluid in the outlet cleaning pipe 7 without stopping the negative pressure suction device 6, so as to reduce the input of cleaning fluid into the patient's stomach flow, thereby reducing patient discomfort.
以上所述的仅是本实用新型的优化实施例，方案中公知的具体结构及特性等常识在此未作过多描述。应当指出，对于本领域的技术人员来说，在不脱离本实用新型结构的前提下，还可以作出若干变形和改进，这些也应该视为本实用新型的保护范围，这些都不会影响本实用新型实施的效果和专利的实用性。本申请要求的保护范围应当以其权利要求的内容为准，说明书中的具体实施方式等记载可以用于解释权利要求的内容。What is described above is only an optimized embodiment of the present utility model, and common knowledge such as specific structures and characteristics known in the scheme are not described too much here. It should be pointed out that for those skilled in the art, under the premise of not departing from the structure of the utility model, some deformations and improvements can also be made, and these should also be regarded as the protection scope of the utility model, and these will not affect the utility model.
