Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a breathing mask used for digestive endoscopy under painless anesthesia. Background Art

[0002] Painless endoscopy usually refers to painless gastrointestinal endoscopy, which is to give the patient appropriate sedatives, hypnotics or narcotic analgesics during endoscopic examination to put the patient in a state of conscious sedation or light anesthesia. The patient is quiet during the operation and has no conscious discomfort. It can eliminate the pain during gastrointestinal endoscopy and avoid common adverse reactions such as coughing, nausea, vomiting, and increased blood pressure. It can ensure that the patient receives timely and necessary endoscopic examinations and treatments, and achieve early diagnosis and early treatment of gastrointestinal diseases.

[0003] The endoscopic examination breathing mask currently in use, such as patent number CN213100206U, named as an oxygen inhalation mask that can be used for endoscopic examination protection, includes a cover shell, an oxygen supply tube port, a catheter port, etc. The endoscopic examination port and the oxygen supply tube port are separately arranged, and the oxygen supply operation can be performed while intubation is performed, which effectively avoids the problem of hypoxia of patients during intubation.

[0004] However, the above-mentioned prior art still has the following deficiencies in clinical operation: first, after the patient wears the above-mentioned breathing mask, intravenous injection is used to anesthetize the patient, and the patient cannot be directly given painless anesthesia through the respiratory tract; second, when the patient is wearing the mask, as the operation time increases, the carbon dioxide concentration in the mask continues to increase, which can easily lead to carbon dioxide retention in the patient's body. Utility Model Content

[0005] In view of the defects existing in the above-mentioned prior art, the utility model proposes a breathing mask for gastrointestinal endoscopy under painless anesthesia, in which an oxygen supply device and an anesthesia machine are simultaneously connected to the delivery tube, so that the patient can inhale oxygen and anesthesia simultaneously, and the purification part in the cavity of the mask body can timely absorb the carbon dioxide exhaled by the patient to avoid carbon dioxide retention in the patient.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0009] The anesthesia oxygen supply part is connected to the end of the mask body close to the top of the patient's head and is used to deliver oxygen and anesthetic drugs to the patient;

[0010] The bottom of the mask body forms a cavity downwards, and a purification part is arranged in the cavity, through which the carbon dioxide exhaled by the patient is absorbed.

[0011] In order to achieve the above purpose, the purification part further includes an outer layer and an inner filler, the outer layer is arranged in the cavity and is circumferentially attached to the inner wall of the mask body, and the inner filler is evenly filled in the outer layer, and the inner filler is a carbon dioxide absorbent.

[0012] By adopting the above solution, further, a plurality of plug-in rods are arranged circumferentially on the outer ring of the outer layer, and each plug-in rod is plugged into a corresponding slot of the mask body.

[0013] A further preferred embodiment of the above technical solution is that the anesthesia oxygen supply part is a delivery tube detachably connected to the mask body.

[0014] Based on the above technical solution, further, the proximal end of the delivery tube is connected to the mask body, and the distal end thereof is provided with a first tube head and a second tube head in sequence from top to bottom, and both the first tube head and the second tube head are communicated with the interior of the delivery tube.

[0015] Based on the above technical solution, further, the first tube head is L-shaped, one end of which is connected to the delivery tube, and the other end is used to connect to the external oxygen tube.

[0016] The above technical solution of the utility model has the following beneficial effects:

[0017] 1. By setting up a purification part, the purification part is connected to the inner wall of the mask body, which includes an outer layer and an inner filler. The inner filler adopts a carbon dioxide absorbent, and the carbon dioxide exhaled by the patient into the cavity is absorbed by the inner filler, which effectively ensures the oxygen concentration in the inner cavity and reasonably avoids the phenomenon of carbon dioxide retention in the patient.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0029] At present, most of the breathing masks on the market are those for endoscopic examination mentioned in the background technology. When such breathing masks are actually used, patients cannot undergo painless anesthesia of the respiratory tract after wearing the breathing masks, and as the carbon dioxide concentration in the mask increases, it is very easy to cause carbon dioxide retention in the patient. In view of the above two defects, based on the convenience and safety of clinical operations, the applicant has combined calcium lime, which is commonly used in clinical practice to adsorb carbon dioxide, into the cavity of the mask, so as to timely adsorb and remove the carbon dioxide exhaled by the patient, and replace traditional intravenous anesthesia with respiratory anesthesia, effectively overcoming the actual problems in clinical applications and ensuring that patients can safely undergo digestive endoscopy under painless anesthesia. Example 1

[0030] Reference Figure 1-6The utility model provides a breathing mask for digestive endoscopy under painless anesthesia, which is disposable in clinical practice and includes a mask body 1 in an outward convex shape. The mask body 1 is made of conventional medical transparent silicone rubber material. An inflation tube 12 is connected to one side of the mask body 1, and air is inflated into the interior of the mask body 1 through the inflation tube 12. An endoscope inspection part 2 and an anesthesia oxygen supply part 3 are arranged on the top of the mask body 1. The endoscope inspection part 2 is located at the corresponding position of the patient's oral cavity. The detection end of the digestive endoscope is extended into the patient's digestive tract through the endoscope inspection part 2 for inspection. The anesthesia oxygen supply part 3 is connected to the end of the mask body 1 close to the top of the patient's head, and is used to deliver oxygen and anesthetic drugs to the patient. The bottom of the mask body 1 forms a cavity downward, and a purification part 4 is arranged in the cavity, and the carbon dioxide exhaled by the patient is absorbed by the purification part 4.

[0031] The top of the mask body 1 is also connected to a plurality of fixing posts 13, such as Figure 3 As shown, a plurality of fixing posts 13 are spaced around the endoscope inspection portion 2. In the present embodiment, four fixing posts 13 are provided. The fixing posts 13 are used to hang the two ends of the elastic band with holes wrapped around the patient's head, so as to seal and fasten the mask body 1 to the patient's facial mouth and nose area.

[0032] Specifically, the endoscopic inspection part 2 includes an extension tube 21 and a sealing cover 22. The extension tube 21 is integrally formed with the mask body 1, and the extension tube 21 forms an inspection channel to the inside of the mask body 1. The detection end of the digestive endoscope enters the patient's oral cavity through the inspection channel. The sealing cover 22 is installed at the tube mouth of the extension tube 21 in a closable manner, and the sealing cover 22 is connected to the outer wall of the extension tube 21 through a connecting strip on one side thereof.

[0033] like Figure 4-6 As shown, the purification part 4 includes an outer layer 41 and an inner filler 42. The outer layer 41 is arranged in the cavity, is in a ring shape and is made of the same material as the mask body 1. The outer layer 41 is connected to the mask body 1 and is circumferentially attached to the inner wall of the mask body 1. The inner filler 42 is evenly filled in the outer layer 41, and the carbon dioxide exhaled by the patient into the cavity is effectively absorbed by the inner filler 42.

[0034] More specifically, a plurality of plug-in rods 43 are arranged in the circumferential direction of the outer ring of the outer layer 41, and a plurality of slots 11 are provided on the inner wall of the mask body 1, such as Figure 5 As shown, in this embodiment, four plug-in rods 43 and four slots 11 are provided, and each plug-in rod 43 is installed in a corresponding slot 11, and a plurality of adsorption holes 44 are provided in the inner circumference of the outer layer 41;

[0035] The inner filler 42 uses a carbon dioxide absorbent, such as medical calcium lime, medical soda lime, etc. Preferably, the inner filler 42 of this embodiment uses medical calcium lime. This material can absorb the carbon dioxide exhaled by the patient very well, and will not react with existing commonly used anesthetics, and will not degrade volatile anesthetics. Usually, the digestive endoscopy examination time is about 10 minutes. A sufficient amount of inner filler 42 is loaded into the outer layer 41 to ensure that the carbon dioxide exhaled by the patient is fully absorbed by the inner filler 42 through the adsorption holes 44 while the patient wears the mask body 1, thereby ensuring the oxygen saturation inside the cavity. Example 2

[0036] On the basis of the above-mentioned embodiment 1, in order to solve the problem of respiratory anesthesia when the patient wears the mask body 1 to inhale oxygen, the following further improvements are made to the anesthesia oxygen supply part 3 of the present application.

[0037] like Figure 1 , Figure 7 As shown, the anesthesia oxygen supply part 3 is a delivery tube, which is detachably connected to the mask body 1, and the proximal end of the delivery tube is connected to the docking tube 14 on the mask body 1. The middle part of the delivery tube is configured as a corrugated tube to increase the flexibility of the direction adjustment of the delivery tube. The distal end of the delivery tube is provided with a first tube head 31 and a second tube head 32 from top to bottom, and the first tube head 31 and the second tube head 32 are both connected to the interior of the delivery tube. The first tube head 31 is L-shaped, one end of which is connected to the delivery tube, and the other end is connected to an external oxygen machine or a ventilator. The second tube head 32 is used to connect to an external anesthesia machine. The delivery tube can be used to safely and efficiently achieve oxygen inhalation and anesthesia for the patient simultaneously. Example 3

[0038] On the basis of the above-mentioned embodiments 1-2, a sampling port 15 for detecting the concentration of carbon dioxide is further provided on the mask body 1 (see Figure 3 , Figure 7 ), the sampling port 15 is located near the docking tube, which can dynamically monitor the carbon dioxide exhaled by the patient in the mask body 1 to further ensure the safety of the patient.

[0039] The utility model discloses a breathing mask for gastrointestinal endoscopy under painless anesthesia. In specific application: first, the mask body 1 is covered on the patient's face, nose and mouth, and is connected to the fixing column 13 after being adjusted appropriately by a perforated elastic band; then, an external oxygen machine or a ventilator is connected at the first tube head 31, and after the patient adapts to the mask oxygen inhalation, the anesthesia machine is connected at the second tube head 32, and the anesthetic drug enters the cavity of the mask body 1 through the delivery tube to perform painless anesthesia on the patient; after the anesthetic drug takes effect, the doctor opens the sealing cover 22, and extends the detection end of the gastrointestinal endoscope through the tube mouth of the extension tube 21 into the patient's oral cavity for inspection; after the inspection is completed, the detection end of the gastrointestinal endoscope is taken out, and the mask body 1 can be removed.

[0040] It should be clear that the above detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
