Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the multifunctional visual hard mirror provided by the present invention is described in detail below with reference to the accompanying drawings.

Example one

As shown in fig. 1 and 2, the multifunctional visual hard mirror of the first embodiment comprises a mirror body 10, wherein the mirror body 10 is pre-sleeved with a tracheal tube and enters the trachea through the throat of a human body together with the tracheal tube. Specifically, before the multifunctional visual hard endoscope is used for tracheal intubation, the tracheal tube is sleeved on the endoscope body 10, then the endoscope body 10 and the tracheal tube are inserted into the throat part of a human body together, and finally the tracheal tube and the endoscope body enter the trachea together. In the process, the endoscope body 10 is equivalent to a guiding structure of a tracheal catheter, the tracheal catheter can move to the vicinity of a glottis (namely a tracheal opening) along with the endoscope body 10, and the whole endoscope body 10 is taken out after the tracheal catheter is smoothly fed into a trachea. The endoscope body 10 has good guidance for the endotracheal tube, and can accurately guide the endotracheal tube to the vicinity of the glottis (i.e., the trachea opening).

The lens body 10 includes a straight section 11 and a bent section 12 which forms an angle with the straight section 11 and is connected with the straight section in a smooth transition manner. Generally, the endoscope body 10 is made of hard materials, the length of the straight section 11 is larger than that of the bent section 12, the straight section 11 and the bent section 12 are in angle and smooth transition connection, and the structure can be more suitable for the throat part and the trachea part of a human body, so that the operation of trachea intubation by using a multifunctional visual hard endoscope is facilitated.

As shown in fig. 1 to 3, the multifunctional visual hard mirror further includes an image capturing device 20 and a display device 30. Image acquisition device 20 sets up on the terminal surface of kink 12, and display device 30 sets up in the one end that straight section 11 deviates from kink 12, and image acquisition device 20 is connected with display device 30 communication. The image capturing device 20 and the display device 30 may be in communication connection in a wired or wireless manner, preferably in a wired manner, so that signal transmission between the image capturing device 20 and the display device 30 can be ensured. Specifically, a through channel (not shown in the figure) may be disposed in the mirror body 10, a signal transmission element such as a coaxial line or a flexible circuit board is disposed in the through channel, and two ends of the signal transmission element are electrically connected to the image acquisition device 20 and the display device 30 respectively.

Further, as shown in fig. 2 to 5 and 7, a multi-functional channel 13 is disposed in the mirror body 10, and the multi-functional channel 13 has a first channel opening 131 and a second channel opening 132 in the extending direction thereof. Wherein the first passage opening 131 is located on the end face of the bending section 12. The second port 132 is selectively used to communicate with one of the oxygen supply tube 200 connected to the oxygen supply device and the gas sampling tube 300 connected to the gas monitoring device, and/or to insert the anesthetic delivery hose 40 connected to the local anesthetic supply device, from the side of the straight section 11.

That is, the multi-function channel 13 can realize the following three functions:

1) providing oxygen

During intubation of the trachea in the awake state, the primary task is to avoid hypoxia. When the second channel port 132 of the multifunctional channel 13 is communicated with the oxygen supply tube 200 connected with the oxygen supply device, oxygen in the oxygen supply device can sequentially enter the human airway through the first channel port 131 of the oxygen supply tube 200, the multifunctional channel 13 and the multifunctional channel 13, so that oxygen is supplied to the human body, oxygen is further conveyed in the process of trachea intubation, and oxygen deficiency is avoided.

2) Monitoring end-tidal carbon dioxide

When the trachea is intubated in a waking state, the main key point of the intubation for dealing with the difficult airway patients is to keep enough spontaneous breathing as far as possible, and the breathing condition (mainly including the breathing frequency and the breathing amplitude) can be reflected most intuitively through the monitoring of the end-expiratory carbon dioxide waveform. When the second channel port 132 of the multifunctional channel 13 is communicated with the gas sampling tube 300 connected with the gas monitoring device, carbon dioxide at the end of human body expiration sequentially passes through the first channel port 131 of the multifunctional channel 13, the multifunctional channel 13 and the gas sampling tube 300 to enter the gas monitoring device, so that the monitoring of the carbon dioxide is realized.

It should be noted that, in order to enhance the accuracy of carbon dioxide monitoring and prevent the pipeline from being blocked by the condensed water generated in the gas sampling tube 300 due to the moisture in the expired air of the human body, a moisture absorption filtering device may be provided in front of the gas sampling tube 300 or in the gas sampling tube 300.

3) Local anesthesia

After the anesthetic delivery hose 40 connected to the local anesthetic supply is inserted into the multi-functional tunnel 13 from the second tunnel opening 132 of the multi-functional tunnel 13, the length of the anesthetic delivery hose 40 extending out of the first tunnel opening 131 of the multi-functional tunnel 13 is adjusted according to the site to be locally anesthetized (e.g., the surface of a certain position of the nasal cavity, oral cavity, and throat region, or airway of the human body). Meanwhile, the endoscope body 10 can be moved to a proper position, so that the medicine outlet end of the anesthetic conveying hose 40 can reach a part needing local anesthesia, and anesthetic liquid medicine in the local anesthetic supply device is conveyed to the medicine outlet end of the anesthetic conveying hose 40 through the anesthetic conveying hose, so that local anesthesia is accurately performed.

It should be noted that the second port 132 of the multi-functional channel 13 may simultaneously communicate with the oxygen supply tube 200 and insert the anesthetic delivery hose 40, may simultaneously communicate with the gas sampling tube 300 and insert the anesthetic delivery hose 40, and may simultaneously communicate with the oxygen supply tube 200 and communicate with the gas sampling tube 300. That is, the multi-functional channel 13 can provide oxygen and local anesthesia simultaneously, can monitor end-tidal carbon dioxide and local anesthesia simultaneously, and can provide oxygen and monitor end-tidal carbon dioxide simultaneously.

Of course, in other embodiments, second port 132 of multi-functional channel 13 may not be in communication with oxygen supply tube 200 and gas sampling tube 300 simultaneously, i.e., not in communication with providing oxygen and monitoring end-tidal carbon dioxide simultaneously, thereby improving carbon dioxide monitoring accuracy.

As shown in fig. 3, in the multifunctional visual hard mirror according to the first embodiment, the image capturing device 20 includes a light source 21 and a camera 22, the camera 22 is used for capturing images, and the light source 21 is used for providing light for capturing by the camera 22. If the end face of the bending section 12 is divided into two symmetrical regions (e.g., two regions divided by a dotted line in fig. 3), the light source 21 and the camera 22 are located in one region, and the first passage port 131 is located in the other region, so that the light of the light source 21 can be prevented from being shielded by the anesthetic conveying hose 40 extending out of the first passage port 131, and the image capturing effect of the camera 22 can be ensured. Of course, in other embodiments not shown in the drawings, the positional relationship among the light source 21, the camera 22 and the first passage port 131 may be designed appropriately as needed.

As shown in fig. 1 and 2, in the first embodiment of the multifunctional hard visual mirror, the multifunctional hard visual mirror further includes a handle 50, and the straight section 11 and the display device 30 are respectively connected to both sides of the handle 50. The handle 50 is primarily for the operator to hold. The lens body 10 further comprises a lateral extension 14, wherein the lateral extension 14 is connected to the straight section 11 and protrudes out of the handle 50 along the lateral direction. Second port 132 is selectively in communication with one of oxygen supply tube 200 and gas sampling tube 300 via lateral extension 14 and/or into anesthetic delivery hose 40. The lateral extension 14 protrudes beyond the handle 50 in the lateral direction of the straight section 11, which further facilitates the handling at the lateral extension 14. Preferably, the lateral extension 14 extends obliquely upward, that is, the distance between the lateral extension 14 and the straight section 11 increases gradually from bottom to top.

As shown in fig. 2, 4, 5 and 7, in the multifunctional visual hard mirror according to the first embodiment, three extension channels are provided in the lateral extension section 14, and one end of each extension channel is communicated with the second channel opening 132. The other end of each extension channel forms a channel interface on the end face of the lateral extension 14. The three channel interfaces are independent. Wherein, the three channel interfaces are respectively used for being communicated with the oxygen supply pipe 200 through the oxygen supply joint structure 60, being communicated with the gas sampling pipe 300 through the sampling joint structure 70 and being placed into the anesthetic conveying hose 40.

Specifically, the three extension passages are an extension passage 15a, an extension passage 15b, and an extension passage 15c, respectively, an end of the extension passage 15a forms a passage interface 151a on an end surface of the lateral extension section 14, an end of the extension passage 15b forms a passage interface 151b on an end surface of the lateral extension section 14, and an end of the extension passage 15c forms a passage interface 151c on an end surface of the lateral extension section 14. The channel interfaces 151a, 151b, and 151c are independent of each other. Wherein, the channel interface 151a is used for communicating with the oxygen supply tube 200 through the oxygen supply joint structure 60, the channel interface 151b is used for communicating with the gas sampling tube 300 through the sampling joint structure 70, and the channel interface 151c is used for placing the anesthetic delivery hose 40.

The three extension channels are respectively used for realizing the functions of providing oxygen, monitoring end-expiratory carbon dioxide and local anesthesia, and are simple in structure and convenient to operate. It should be noted that, when the channel interface 151a is connected to the oxygen supply tube 200 through the oxygen supply joint structure 60, the channel interface 151a and the oxygen supply joint structure 60 and the oxygen supply tube 200 are connected in a sealing manner, so as to avoid oxygen leakage. When the channel interface 151b is communicated with the gas sampling tube 300 through the sampling joint structure 70, the channel interface 151b and the sampling joint structure 70 and the gas sampling tube 300 should be in sealing connection, so that the monitoring accuracy of the carbon dioxide is ensured. When the anesthetic delivery hose 40 is inserted into the extension passage 15c and the multi-functional passage 13 through the passage interface 151c, the anesthetic delivery hose 40 may not be sealed with the passage interface 151 c.

Further, as shown in fig. 4 and 5, in the multifunctional visual hard mirror of the first embodiment, the oxygen supply joint structure 60 includes an oxygen tube connection end 61 and a first interface connection end 62 which are connected to each other. The outer diameter of the oxygen tube connecting end 61 is adapted to the inner diameter of the oxygen supply tube 200, for example, the outer diameter of the oxygen tube connecting end 61 is the same as the inner diameter of the oxygen supply tube 200, or the outer diameter of the oxygen tube connecting end 61 is slightly smaller than the inner diameter of the oxygen supply tube 200, so that the oxygen tube connecting end and the oxygen supply tube are conveniently inserted. The outer diameter of the first interface connection end 62 is matched with the inner diameter of the corresponding channel interface (i.e. the channel interface 151a), for example, the outer diameter of the first interface connection end 62 is the same as the inner diameter of the channel interface 151a, or the outer diameter of the first interface connection end 62 is slightly smaller than the inner diameter of the channel interface 151a, so as to facilitate the insertion of the two.

Additionally, the sample fitting structure 70 includes a sample tube connection end 71 and a second interface connection end 72 that are connected to each other. The external diameter of sampling pipe connection end 71 and the internal diameter of gas sampling pipe 300 are adapted, for example, the external diameter of sampling pipe connection end 71 is the same as the internal diameter of gas sampling pipe 300, or the external diameter of sampling pipe connection end 71 is slightly less than the internal diameter of gas sampling pipe 300, thereby facilitating the insertion of the two. The outer diameter of the second interface connection end 72 is adapted to the inner diameter of the corresponding channel interface (i.e. the channel interface 151b), for example, the outer diameter of the second interface connection end 72 is the same as the inner diameter of the channel interface 151b, or the outer diameter of the second interface connection end 72 is slightly smaller than the inner diameter of the channel interface 151b, so that the two interfaces can be conveniently plugged.

As shown in fig. 6, in this embodiment, the three passage ports may be sealed by three sealing plugs, and each sealing plug may selectively block or avoid the corresponding passage port. In general, when the function corresponding to one of the port connectors is not required to be used, the port connector is sealed by a sealing plug. Similarly, when a function corresponding to a certain channel interface needs to be used, the sealing plug at the channel interface needs to be removed to avoid the channel interface.

It should be noted that two sealing plugs corresponding to two channel interfaces for communicating the oxygen supply tube 200 and the gas sampling tube 300 can simultaneously plug, or one sealing plug plugs the corresponding channel interface and the other sealing plug avoids the corresponding channel interface. That is, the two channel interfaces (channel interface 151a and channel interface 151b) for implementing the functions of providing oxygen and monitoring end-tidal carbon dioxide are not in an open state at the same time.

Specifically, as shown in fig. 6, the three sealing plugs are a sealing plug 80a, a sealing plug 80b, and a sealing plug 80c, respectively, the sealing plug 80a is used for sealing the passage interface 151a, the sealing plug 80b is used for sealing the passage interface 151b, and the sealing plug 80c is used for sealing the passage interface 151 c. Wherein the sealing plug 80a and the sealing plug 80b are connected by a flexible connecting strip. Since the passage connection 151a and the passage connection 151b cannot be opened at the same time, that is, at least one of the sealing plugs 80a and 80b should be in a state of blocking the respective passage connection. When one of the sealing plugs 80a and 80b blocks the corresponding passage connection, the sealing plug can be regarded as being fixed at the corresponding passage connection, while the other sealing plug can be connected with the sealing plug through a flexible connecting strip, thereby preventing the removed sealing plug from being lost. For example, in fig. 6 the sealing plug 80a is fixed at the respective passage interface and the sealing plug 80b is connected to the sealing plug 80a by a flexible connecting strip, thereby preventing the removal of the sealing plug 80 b. In addition, the sealing plug 80c is connected to the outer peripheral wall of the lateral extension 14 by a flexible connecting strip, which also prevents the sealing plug 80c from being lost after being removed.

It should be noted that, for more flexible and convenient use, the inner diameters of the three channel interfaces may be set to be the same, and at this time, the specific function corresponding to each channel interface is not limited, that is, the oxygen supply joint structure 60 and the oxygen supply tube 200 may be connected to any one of the three channel interfaces as required, and similarly, the sampling joint structure 70 and the gas sampling tube 300 may also be connected to any one of the three channel interfaces as required, and the anesthetic delivery hose 40 may also be placed into the corresponding extension channel from any one of the three channel interfaces as required.

As shown in fig. 7 and 8, in the multi-functional visual hard mirror according to the first embodiment, the anesthetic delivery hose 40 has an anesthetic injection end 41 (i.e., a medicine discharge end), and the anesthetic injection end 41 is generally an end of the anesthetic delivery hose 40 away from a local anesthetic supply device (e.g., a local anesthetic supply device capable of performing a high-pressure spray injection). The pipe wall of the anesthetic spraying end 41 is provided with a plurality of spraying holes 411, and the plurality of spraying holes 411 are uniformly distributed along the circumferential direction and the axial direction of the anesthetic conveying hose 40, so that anesthetic liquid medicine can be uniformly sprayed along all directions, and local anesthesia can be better performed. It should be noted that the specific arrangement of the plurality of injection holes 41 is not limited, as long as the plurality of injection holes 41 are uniformly distributed, for example, the plurality of injection holes 41 are divided into a plurality of rows along the axial direction of the anesthetic delivery hose 40, and the injection holes 41 in each adjacent two rows of injection holes 41 are axially aligned or staggered. In addition, the outer diameter of the anesthetic delivery hose 40 generally needs to be smaller than the inner diameters of the multi-functional channel 13 and the extension channel so that the anesthetic delivery hose 40 can be smoothly introduced.

Example two

As shown in fig. 9 and 10, the main difference between the multifunctional visual hard mirror of the second embodiment and the first embodiment is that two extension channels are arranged in the lateral extension section 14, and one end of each extension channel is communicated with the second channel opening 132. The other end of each extension channel forms a channel interface on the end face of the lateral extension 14. The two channel interfaces are independent of each other. Wherein, one passage interface is selectively used for communicating with the oxygen supply pipe 200 through the oxygen supply joint structure 60 or communicating with the gas sampling pipe 300 through the sampling joint structure 70, and the other passage interface is used for placing the anesthetic delivery hose 40.

Specifically, the two extension passages are an extension passage 15d and an extension passage 15e, respectively, an end of the extension passage 15d forms a passage interface 151d on the end face of the lateral extension section 14, and an end of the extension passage 15e forms a passage interface 151e on the end face of the lateral extension section 14. The channel interface 151d and the channel interface 151e are independent of each other. Wherein, the channel interface 151d is selectively used for communicating with the oxygen supply tube 200 through the oxygen supply joint structure 60 or communicating with the gas sampling tube 300 through the sampling joint structure 70, and the channel interface 151e is used for placing the anesthetic delivery hose 40.

In this embodiment, the passage ports 151d and 151e are sealed by sealing plugs 80d and 80e, respectively. The sealing plug 80d and the sealing plug 80e are respectively connected with the outer peripheral wall of the lateral extension section 14 through flexible connecting strips, so that the phenomenon that the sealing plug 80d and the sealing plug 80e are lost after being taken down can be prevented. The multifunctional visual hard mirror in the second embodiment is basically the same as the other structures and working principles of the first embodiment, and is not described herein again.

EXAMPLE III

As shown in fig. 11, the main difference between the multifunctional visual hard mirror of the third embodiment and the first embodiment is that a guiding cylinder 16 is disposed at a channel interface (e.g., channel interface 151c) for inserting the anesthetic delivery hose 40, the guiding cylinder 16 is disposed coaxially with the channel interface, and the inner diameter of the guiding cylinder 16 gradually increases from the channel interface to the channel interface. The guiding cylinder 16 is substantially in a bell mouth shape, and when the anesthetic delivery hose 40 is inserted from the channel interface, the guiding cylinder 16 can guide the anesthetic delivery hose 40, so as to smoothly guide the anesthetic delivery hose 40 to the corresponding extension channel (for example, the extension channel 15c) and the multifunctional channel 13. The multifunctional visual hard mirror in the third embodiment is basically the same as the other structures and working principles of the first embodiment, and is not described herein again.

It will be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the utility model, and these modifications and improvements are also considered to be within the scope of the utility model.
