Hereinafter, an embodiment of the present invention will be described in accordance with its entire structure.

Example 1:

as shown in fig. 1-6, the combined sleeve for auxiliary gastroscope comprises a hose body 1 provided with an interlayer 10, a hard joint 17 and a first air bag 12, wherein the hard joint 17 comprises a first supporting section 15 and a second supporting section 11 which are communicated, one end of the second supporting section 11 away from the first supporting section 15 is communicated with the hose body 1, and a blocking plate 18 is arranged around the circumference of the second supporting section 11; one end of the first supporting section 15, which is far away from the first air bag 12, is a gastroscope inlet, the gastroscope inlet is covered with a film structure 16, the first air bag 12 is arranged around the hose main body 1, and a plurality of through holes and pipelines matched with the through holes are arranged between the first air bag 12 and the hard joint 17; an inflation pipeline 101 is further arranged in the interlayer 10, one end of the inflation pipeline 101 is communicated with the first airbag 12, and an esophageal bag inflation inlet 111 is arranged at the other end of the inflation pipeline 101. In this embodiment, the first air bag 12 is in a contracted state at first, and after the hose body 1 is inserted into the esophagus, the first air bag 12 is inflated to fill the gap between the esophagus and the hose body 1, and the esophagus is closed. Wherein, in order to facilitate the respiration of the patient, a plurality of through holes are arranged between the hard joint 17 and the first air bag 12, a pipeline matched with the through holes is arranged in the interlayer 10, and one end of the pipeline away from the through holes extends to the second supporting section 11. The through hole can send oxygen to the throat through the pipeline, improves the oxygen suppliment, also can suck back the palirrhea liquid or the sputum of accumulating of patient's throat, prevents the emergence of the scheduling problem of choking, throat spasm or mistake inhale, can monitor the carbon dioxide that breathes and produce simultaneously to judge patient's respiratory state.

Wherein, in order to prevent the hose body 1 and the gastroscope from being damaged due to occlusion of a patient, the hard joint 17 comprises a first support section 15 and a second support section 11. The second support section 11 together with the blocking plate 18 constitutes a bite head, the teeth of the patient being blocked by the blocking plate 18, biting into the end of the second support section 11 remote from the first support section 15. This design both protects the hose body 1 and prevents the hard joint 17 from penetrating too far into the patient's mouth.

In order to facilitate inflation, an inflation pipeline 101 is further disposed in the interlayer 10, one end of the inflation pipeline 101 is communicated with the first air bag 12, and an esophageal bag inflation inlet 111 is installed at the other end of the inflation pipeline 101.

Preferably, the through hole further comprises a sputum suction port 105, a liquid passing pipeline 104 is further arranged in the interlayer 10, one end of the liquid passing pipeline 104 is connected with the sputum suction port 105, and a sputum suction joint 114 is arranged at the other end of the liquid passing pipeline 104. The oxygen joint 112, the carbon dioxide joint 113 and the sputum suction joint 114 in the scheme are all standard interfaces, and the oxygen joint 112 is used for connecting oxygen supply equipment so as to supply oxygen to a patient; the carbon dioxide connector 113 is used for connecting carbon dioxide detection equipment and is used for detecting carbon dioxide exhaled by a patient and monitoring whether the patient breathes smoothly or not; the sputum aspirator 114 is used for connecting a sputum aspirator, and the sputum aspirator is used for aspirating the reflux liquid or the accumulated sputum of the throat of the patient after the hose body 1 is installed in place, so that the situations of choking, throat cramping, aspiration error and the like are prevented.

Preferably, the carbon dioxide joint 113 and the access point of the sputum suction joint 114 in this embodiment are located between the first support section 15 and the barrier plate 18, i.e. in a partial area of the second support section 11. And the oxygen connector 112 is located on the side wall of the first support section 15.

In order to avoid under-inflation caused by the escape of inflation air or carbon dioxide during gastroscopy, the rigid coupling 17 comprises a channel communicating with the hose body 1, one end of which channel covers a membrane structure 16 with an opening. The film structure 16 is used for blocking the gastroscope entrance when idle, and when in use, the film structure 16 is opened, the gastroscope passes through the space generated when the film structure 16 is opened and enters the hose body 1, and the film structure 16 is filled in the gap between the gastroscope and the hard joint 17, so that the overflow of air and carbon dioxide is reduced. Preferably, the opening of the membrane mechanism 16 is cross-shaped. The design enables the membrane structure 16 to be adapted to gastroscopes of different diameters, and the membrane structure 16 can be uniformly arranged in a gap between the hard joint 17 and the gastroscope when opened, so that tightness is ensured.

The first balloon 12 in this embodiment not only serves as a seal, but also serves to compress bleeding from the bleeding site in the esophagus. This design greatly reduces the risk of reflux in gastroscopy or therapy, especially under sedated or anesthetized conditions. In addition, for the patients diagnosed with bleeding of the fundus and the lower esophageal segment (such as bleeding of fundus-esophageal varices, etc.), or bleeding and even difficult bleeding during treatment of the fundus and the lower esophageal segment, the rubber hose 2 is introduced to play a role in compression hemostasis. The rubber hose 2 is sleeved in the hose body 1, a second air bag 21 is installed at one end of the rubber hose 2, a first interface 23 and a second interface 24 are installed at the other end of the rubber hose 2, a third air bag 22 is installed between the second air bag 21 and the first interface 23, a first ventilation pipe 25 is arranged between the first interface 23 and the second air bag 21, and a second ventilation pipe 26 is arranged between the second interface 24 and the third air bag 22. The diameter of the rubber hose 2 is far smaller than the aperture of the hose body 1, so that only the bottom end of the rubber hose 2, that is, the ends of the second air bag 21 and the third air bag 22, need to be sent into the esophagus and the stomach of a patient along the hose body 1 when in use. Wherein, the second air bag 21 is located in stomach, the third air bag 22 is located in the bottom of esophagus, both of them play the role of compressing the bottom of stomach, lower end of esophagus respectively, in addition the second air bag 21, the third air bag 22 play the role of preventing patient from flowing backward, inhaling by mistake. For special situations such as hemostasis by compression difficulty, can withdraw from the hose main part 1 the back, can carry out the trachea cannula operation of transoral, the rubber hose 2 can effectively prevent backward flow, the emergence of mistake suction in the trachea cannula in-process, does not hinder trachea cannula operation simultaneously.

Preferably, the length of the rubber hose 2 is longer than the length of the hose body 1. When the rubber hose 2 is used in combination with the hose body 1, the second bladder 21 and the third bladder 22 are both located outside the hose body 1, and the purpose is to prevent the hose body 1 from obstructing the inflation of the bladders. Wherein, the first air bag 12, the third air bag 22 and the second air bag 21 are distributed from top to bottom in sequence.

In this embodiment, the esophageal balloon inflation port 111 is connected to a balloon pressure detector for the purpose of detecting the pressure within the first balloon 12. When the air bag is inflated, the air bag pressure detector detects the pressure in the air bag, and when the pressure reaches a specified limit value, the inflation equipment stops inflating; after the air bag is fully inflated, the air bag is in a slowly deflating state, and when the pressure in the air bag is reduced to a specified value, the air inflation equipment inflates the air bag again.

In order to conform to the length of the esophagus of the Chinese patient, the length of the hose body 1 is about 22 cm-25 cm, the length of the hard joint 17 is about 1.5 cm-3 cm, the distance between the blocking plate 18 and the sputum suction opening 105 is about 8 cm-12 cm, the length of the first air bag 12 is about 4 cm-7 cm, the outer contour dimension of the first air bag 12 after expansion is 3.2 cm-3.6 cm, and the length of the second support section 11 is about 2 cm-3 cm. The length of the rubber hose 2 is 53-56 cm, the length of the third air bag 22 is 9-11 cm, the outer diameter of the third air bag 22 after expansion is 3.2-3.6 cm, and the outer diameter of the second air bag 21 after expansion is 4.5-5.5 cm.

In this solution, the rigid joint 17 (comprising the blocking plate 1) is of non-toxic rigid construction, the purpose of which is to prevent the problem of damage to the gastroscope caused by the patient's bite.

In summary, the scheme has the following advantages: first, the first balloon 12 not only plays a sealing role, but also can perform compression hemostasis on bleeding parts in the esophagus. Therefore, the device can be used for assisting Endoscopic Submucosal Dissection (ESD), endoscopic Retrograde Cholangiopancreatography (ERCP) and other gastroscopic operations; secondly, the hemostasis and treatment are carried out on patients with gastroesophageal hemorrhage, and the tracheal intubation is assisted in emergency situations, so that reflux and aspiration are prevented; third, can be used for hardening treatment (EVS) or ligation treatment (EVL) of endoscopic fundus-esophageal varices hemorrhage; fourth, can be used for gastroscopy or treatment of high reflux, mistake and induced draft patient.

Example 2:

the combination sleeve of example 1 can be reused, and requires special personnel to perform flushing, cleaning and disinfection. However, this is labor-intensive and for this purpose, a special cleaning device is required for the combined sleeve.

As shown in fig. 7-11, for this purpose, an auxiliary sleeve cleaning and disinfecting mechanism comprises a tank body 4 and a top cover 5, wherein a spraying mechanism 51 is installed at one end of the top cover 5 facing the tank body 4, a waste water collecting box 41 is installed at the bottom of the tank body 4, a cleaning tank 42 is installed between the spraying mechanism 51 and the waste water collecting box 41, a sewage pipeline 43 is installed between the cleaning tank 42 and the waste water collecting box 41, a plurality of ceramic pressing sheets 421 are installed at the bottom of the cleaning tank 42, and the ceramic pressing sheets 421 are uniformly arranged around the sewage pipeline 43. In use, the top cover 5 of the box body 4 is opened, the combined sleeves are coiled respectively and then placed in the washing tank 42, and the spraying mechanism 51 injects enzyme washing liquid into the washing tank 42 until the enzyme washing liquid is out of the combined sleeves. Then, the ceramic pressing sheet 421 is started, and the ultrasonic waves generated by the ceramic pressing sheet 421 drive the enzyme washing liquid in the washing tank 42 to vibrate, so that micro bubbles are generated in the enzyme washing liquid during vibration, and the micro bubbles impact the stains on the combined sleeve and take the stains away from the combined sleeve. After the completion of the enzyme washing, the enzyme washing liquid in the washing tank 42 is sent to the waste water collection tank 41 through the sewage pipe 43. After the enzyme washing liquid is discharged, the spraying mechanism 51 sprays clear water and alcohol into the washing tank 42 in sequence, and the above process is repeated to complete the washing of the combined sleeve.

Since the gastroscope is stained with the digestive juice, and the gastroscope is scraped with the hose body 1 when the gastroscope is taken out from the hose body 1, the digestive juice stained with the gastroscope is inevitably transferred into the hose body 1. However, the ultrasonic cleaning is only suitable for cleaning the outside of the pipe, and for convenience in cleaning the inside of the pipe, it is preferable that a first multi-way valve 44 is installed between the spray mechanism 51 and the cleaning tank 42, a plurality of storage tanks 45 are installed at the side wall of the cleaning tank 42, a liquid passing pipe 451 is installed between the storage tanks 45 and the first multi-way valve 44, and an inner pipe 46 is installed between the first multi-way valve 44 and the cleaning tank 42. The plurality of storage tanks 45 are respectively an enzyme washing liquid storage tank, a clear water storage tank and an alcohol storage tank, the liquid-passing pipeline 451 respectively sends the enzyme washing liquid, clear water and alcohol to the first multi-way valve 44, the first multi-way valve 44 is communicated with the inner-way pipeline 46, and the first multi-way valve 44 controls the enzyme washing liquid, clear water and alcohol to respectively enter the inner-way pipeline 46. Wherein the end of the inner communication tube 46 remote from the first multi-way valve 44 mates with the gastroscope inlet of the second support section 11, i.e. the gastroscope inlet is connected with the inner communication tube 46. The design ensures that enzyme washing liquid, clear water and alcohol can effectively wash the inside of the hose body 1.

In order to facilitate the free switching of the spray liquid by the spray mechanism 51, a second multi-way valve 47 is installed between the first multi-way valve 44 and the top cover 5, a liquid passing pipe 451 is also installed between the second multi-way valve 47 and the plurality of storage tanks 45, and a liquid discharging pipe 471 is installed between the second multi-way valve 47 and the spray mechanism 51. The design enables the second multi-way valve 47 to sequentially send the specified spraying liquid to the spraying mechanism 51 according to the setting, and the outer wall of the combined pipeline is cleaned.

The storage tank 45 in this embodiment is internally provided with a suction pump, the purpose of which is to power the flow of cleaning liquid.

Example 3:

in the embodiment 2, the cleaning of the inner part and the outer part of the combined sleeve is completed, and the cleaned combined pipeline needs to be stored after being dried. In order to avoid the need of taking out the combined sleeve from the machine for airing operation, the cleaning and sterilizing mechanism in the scheme integrates a drying function. As shown in fig. 9, for this purpose, a hot blast box 48 is mounted on the side wall of the box 4, exhaust pipes 481 are mounted between the hot blast box 48 and the first multi-way valve 44 and the second multi-way valve 47, and an exhaust port 482 is provided on the side of the box 4 away from the hot blast box 48. The function of the hot air box 48 is to generate dry hot air, then the dry hot air is sent to the first multi-way valve 44 and the second multi-way valve 47 through the exhaust pipeline 481, then the dry hot air is respectively dried inside and outside the combined pipeline through the spraying mechanism 51 and the inner communication pipeline 46, water vapor is carried away from the combined pipeline, and finally flowing air carrying the water vapor is discharged through the exhaust port 482.

The hot air box 48 is formed of a blower and a heating assembly, and since this technology is a well-known technology, it will not be described in detail.

Preferably, the end of the top cover 5 facing the box body 4 is also provided with an ultraviolet sterilizing lamp 52. The ultraviolet disinfection lamp 52 in the scheme has the functions that firstly, when the cleaning mechanism is idle, the cleaning mechanism is started to disinfect the inside of the cleaning mechanism uninterruptedly; and secondly, further sterilizing the combined pipeline.

The enzyme washing liquid in the scheme is prepared by compounding neutral proteolytic enzyme, lipase, amylase and other multienzymes, and is very suitable for cleaning a combined pipeline because of no corrosion and aging effects on various precise instruments and medical instruments. However, enzyme washes are sensitive to temperature, for example, in winter, due to low temperature of the enzyme wash itself and the environment, the efficiency of the enzyme wash is reduced, and the combined pipeline cannot be cleaned sufficiently. For this purpose, a heating wire 422 is provided on a sidewall of the washing tank 42, the heating wire 422 is provided around the washing tank 42, and a temperature detecting member (not shown in the drawing) is connected to the heating wire 422, and when it is detected that the temperature of the washing tank 42 is low, the heating wire 422 is started to heat the washing tank 42. When the temperature reaches the predetermined value, the heating wire 422 stops heating and is turned into a heat-retaining state.

Example 4:

in order to ensure that the shower mechanism 51 can sufficiently clean the outer wall of the combination pipe, this embodiment is modified on the basis of embodiment 1.

As shown in fig. 11, the spraying mechanism 51 includes a fixed housing 511 and a spraying disc 512, one end of the fixed housing 511 is connected with the top cover 5, one end of the spraying disc 512 facing the fixed housing 511 is provided with a connection section 5121, one end of the spraying disc 512 far from the fixed housing 511 is provided with a plurality of nozzles 5124, one end of the connection section 5121 far from the spraying disc 512 is rotatably connected with a liquid discharge pipe 471, and the connection section 5121 is rotatably connected with the fixed housing 511; the driving motor 5111 is installed in the fixing housing 511, a first gear 5112 is installed at the power output end of the driving motor 5111, a plurality of protruding structures 5122 are arranged on the side wall of the connecting section 5121, and the first gear 5112 is in meshed connection with the protruding structures 5122. The drain 471 is rotatably connected to one end of the connecting section 5121, and the connecting section 5121 is rotatably connected to the fixing case 511. The design makes driving motor 5111 can drive spray dish 512 rotation, and the impact force of the washing liquid that the pivoted spray dish 512 sprayed to the combination pipeline outer wall is stronger, therefore can further wash the combination pipeline outer wall.

Because the driving motor 5111 is installed at the position of the inner eccentric side wall of the fixed shell 511, the rotation space of the first gear 5112 is smaller due to the design, namely, if the first gear 5112 is larger, the first gear 5112 can not rotate, so that the first gear 5112 drives the protruding structure 5122 to rotate, a second gear 5113 is arranged between the connecting section 5121 and the first gear 5112, and the second gear 5113 is respectively connected with the first gear 5112 and the protruding structure 5122 in a meshed manner. This design allows the first gear 5112 to be reduced in volume, avoiding the inner wall of the fixed case 511 from obstructing the rotation of the first gear 5112.
