Description

CROSS-REFERENCES TO RELATED APPLICATIONS This application is a continuation of International Application No. PCT/JP2022/010496 filed on Mar. 10, 2022, which claims priority to Japanese Application No. 2021-054840 filed on Mar. 29, 2021, the entire content of both of which is incorporated herein by reference. TECHNOLOGICAL FIELD The present disclosure generally relates to an adhesive material injection device. BACKGROUND DISCUSSION In the related art, there has been known a procedure of introducing various medical elongated bodies (for example, introducer sheaths) into a blood vessel through a puncture site formed in the blood vessel of a limb such as an arm of a patient and performing treatment and therapy on a lesion site. When such a procedure is performed, a surgeon performs hemostasis on the puncture site when removing the medical elongated body from the puncture site. As one of hemostasis methods, there is known a compression hemostasis method of applying a compressive force to the puncture site of the blood vessel or a subcutaneous tissue around the puncture site from a living body surface layer side of the patient. However, when the compression hemostasis method is adopted, blood vessel occlusion may occur when excessive compression, which means the compressive force is excessively large, is performed for a long time. Therefore, the surgeon is required to appropriately adjust the compressive force. Concerning such a technical problem, the following International Patent Application Publication No. WO00/030553 discloses a hemostatic device that enables non-compression hemostasis. The hemostatic device in International Patent Application Publication No. WO00/030553 includes a sheath insertable into a living body and a cartridge charged with a hemostasis agent held inside the sheath. In a procedure using the hemostatic device in International Patent Application Publication No. WO00/030553, the surgeon introduces a distal opening of the sheath to the periphery of the puncture site of the blood vessel and discharges the hemostasis agent through the distal opening. The surgeon can close the puncture site by disposing the hemostasis agent discharged from the sheath around the puncture site of the blood vessel. The above hemostatic device includes a stopper (locking member) that helps prevent a distal portion of the sheath from being inserted beyond a depth of the puncture site of the blood vessel. The stopper is mounted on an outer peripheral surface of the sheath, and when the sheath is inserted into the living body, the stopper comes into contact with the living body surface layer of the patient to limit an insertion length of the sheath. According to the above hemostatic device, the sheath can be prevented from being excessively inserted into the blood vessel beyond the depth of the puncture site of the blood vessel. However, when the above hemostatic device is used, the surgeon cannot grasp an accurate position of the puncture site of the blood vessel when starting the discharge of the hemostasis agent. Therefore, the surgeon needs to dispose the distal opening of the sheath at the puncture site of the blood vessel depending on a hand feeling. Therefore, in the procedure using the hemostatic device, it can be difficult to appropriately position the distal opening of the sheath with respect to the puncture site of the blood vessel. SUMMARY An adhesive material injection device is disclosed, which is capable of indwelling an adhesive material at an appropriate position with respect to a puncture site formed in a living body lumen. An adhesive material injection device according to the present disclosure includes: a tubular member including a plurality of lumens; and an adhesive material held in the lumen of the tubular member. The tubular member includes a first lumen extending between a first distal opening and a first proximal opening and a second lumen extending between a second distal opening and a second proximal opening at a position different from the first lumen. The first distal opening is located on a distal side relative to the second distal opening in a longitudinal direction of the tubular member. The adhesive material is held in the first lumen between the first distal opening and the first proximal opening. According to the present disclosure, the tubular member has the first distal opening and the second distal opening located on a proximal side of the first distal opening. The adhesive material is held in the first lumen extending between the first distal opening and the first proximal opening. Further, in the adhesive material injection device, the first distal opening through which the adhesive material can be discharged is located on the distal side relative to the second distal opening through which blood can flow in. A puncture foramen formed in a puncture site of a patient for introducing a medical elongated body is formed at an acute angle with respect to a blood vessel from a skin
